JUDGMENT AND REASONS
I.
Overview
[1]
In what is in the process of becoming a
veritable saga concerning its Apo-Omeprazole Magnesium Tablets [or Apo-Omeprazole],
the applicant is once again before this Court on a judicial review application,
presumably pursuant to section 18.1 of the Federal Courts Act (RSC,
1985, c F-7). The relief sought is concerned with the decision of the Minister
of Health [the Minister or the respondent] to cancel the reconsideration of
Apotex’s submission concerning a Notice of Compliance [NOC] in respect of Apotex’s
Apo-Omeprazole (omeprazole magnesium) Tablets and to treat its submission as
withdrawn. That is the decision of the Minister of November 16, 2015,
cancelling the reconsideration which the applicant wants squashed; the
applicant also seeks that the Minister continue to process its submission
without fettering her discretion “by insisting on
strict compliance with policies and guidelines which do not have force of law”.
The applicant seeks an alternative remedy:
•
to direct the Minister to submit its preferred
question to a reconsideration panel;
•
to direct that it be afforded two hours to argue
its case relative to its preferred question;
•
to direct that it be permitted to make
submissions to the Reconsideration Panel concerning “missed
opportunities” for dispute prevention and/or earlier resolution of the
dispute;
•
to direct the Minister’s delegates to be
prohibited from having ex parte discussions with the Reconsideration
Panel.
[2]
The applicant, Apotex Inc. [Apotex],
manufactures and distributes pharmaceutical products, primarily generic
versions of drugs that were first marketed by other manufacturers. All drug
manufacturers must obtain a NOC from the Minister of Health to sell new drug
products in Canada (section C.08.002(1) of the Food and Drug Regulations,
CRC, c 870 [Regulations]). A NOC can be obtained in several ways. In
this case, the mechanism for seeking a NOC for a generic version of an existing
approved drug is the “abbreviated new drug submission”
[or ANDS]. If the ANDS meets the requirements of the Food and Drugs Act [the
Act], RSC, 1985, c F-27 and the Food and Drug Regulations, the Minister
issues a NOC (para C.08.004(1)(a)).
[3]
One of the criteria that an ANDS must meet is
demonstrating that the drug is “bioequivalent”
to the existing drug, referred to as the “Canadian
reference product” [or CRP]. Bioequivalence is not defined in the Regulations,
but Health Canada has published guidelines on how companies can demonstrate
bioequivalence. For our purpose, it will suffice to refer to the notion of “bioequivalent” as described by Dr. Scott Appleton,
who testified by affidavit for the respondent. Dr. Appleton holds degrees in
pharmacology and toxicology, including a Doctorate (Ph. D.), as well as a
Post-Doctoral Fellowship from Tulane University. He described bioequivalence at
para 22 of his affidavit:
The generic drug
is considered to be bioequivalent to the CRP once it has been determined that
it can be expected to have the same systemic effects as the CRP when
administered to patients under the conditions specified in the labeling of the
"innovative drug".
[4]
Apotex originally filed an ANDS in 2000 for “Apo-Omeprazole” tablets, an anti-ulcer drug. That
submission was understood to be approved on March 7, 2003, given that the
examination of the submission had been completed but placed on patent hold. In
other words, the NOC would not issue until requirements of the Patented
Medicines (Notice of Compliance) Regulations (SOR/93-133) were met,
which, as I understand it, was on the expiration of a patent owned by
AstraZeneca Canada Inc. (Apotex Inc. v Canada (Health), 2012 FCA 322 [Apotex],
at para 4). Health Canada later revoked approval because the ANDS lacked a
study showing bioequivalence to the CRP when the drug is taken with a high
calorie/high fat meal. Eventually, in 2013, Apotex submitted a high calorie/high
fat study (OMEC03), but the Minister refused to issue a NOC because she was not
satisfied with the results of the study and the study design.
[5]
Apotex pursued a reconsideration process offered
by Health Canada, but the Minister ultimately refused reconsideration after the
parties could not agree on a proper question to put to an external expert
panel. Health Canada wanted to focus on bioequivalence and the only study,
actually conducted in 1998, offered to demonstrate bioequivalence under fed
conditions, the main reason why the approval given earlier had been revoked
through a “Notice of Non-Compliance Withdrawal Letter”
[or NONW] of February 9, 2009. In fact, the need to consider bioequivalence
under fat fed conditions goes back to December 2008 when the Minister advised
Apotex that its original examination was not completed in spite of the letter
of March 2003. I note that this initial ANDS, which did not include a fat fed study
resulted in the notice of Notice of Non-Compliance Withdrawal Letter on
February 9, 2009. The Minister denied a request for reconsideration on July 27,
2009. An ANDS was resubmitted in 2013. It is that process which started in 2013
that gives rise to this latest judicial review application.
[6]
The record at the time the decision was made to
refuse reconsideration, on November 16, 2015, shows that Apotex’s proposed
questions focused on whether Apo-Omeprazole was “safe
and effective” rather than “bioequivalent”.
During the hearing of this case, Apotex’s counsel suggested that the company
knew it had to show bioequivalence, but hesitated to use that term in proposing
reconsideration questions because it was concerned the Minister was fettering
her discretion by strictly applying the bioequivalence standards in the
guidelines. That was certainly not evident on the face of the exchanges, over a
number of weeks, between Apotex and the Minister’s agents. Rather, the evidence
points in the direction of Apotex seeking to circumvent the requirement to show
bioequivalence.
[7]
Apotex is asking the Court to quash the
Minister’s November 16, 2015, decision to cancel the reconsideration process.
The applicant argues that the Minister’s proposed question results from the
fettering of the Minister’s discretion and does not meet its legitimate
expectations. The respondent argues firmly that the question submitted by the
Minister does not signal any fettering of its discretion and the applicant
cannot validly expect that its question will prevail. Furthermore, the
respondent argues that the matter cannot be returned for the reconsideration to
take place on the basis that the question proposed by the Minister would be
reasonable. In the view of the respondent, that is an alternative that is not
possible since it is not a remedy sought by the applicant in its notice of
application of December 1, 2015.
[8]
For the reasons that follow, there is no
fettering of discretion and the legitimate expectations of the applicant are
not defeated.
II.
Legislative and policy framework
[9]
Setting out the legislative and policy framework
within which a manufacturer like Apotex obtains a NOC provides necessary
context for the facts. There are three key legislative and policy aspects to
this file: obtaining a NOC for an ANDS; meeting the “bioequivalence”
criterion; and the reconsideration process.
[10]
A NOC following an abbreviated new drug
submission is based on less information than would be the case for a completely
new drug, but the Canadian reference product and the drug for which compliance
is sought must be, inter alia, bioequivalent. The requirement for a drug
manufacturer to obtain a NOC before selling a new drug in Canada is set out
under subsection C.08.002(1) of the Regulations. That provision provides
that an ANDS, but also other types of submissions, must be “satisfactory” to the Minister for her to issue the
NOC:
C.08.002 (1) No person shall sell or
advertise a new drug unless
|
C.08.002 (1) Il est interdit de vendre ou d’annoncer une drogue nouvelle, à
moins que les conditions suivantes ne soient réunies :
|
(a) the manufacturer of the new drug
has filed with the Minister a new drug submission, an extraordinary use new
drug submission, an abbreviated new drug submission or an abbreviated
extraordinary use new drug submission relating to the new drug that is
satisfactory to the Minister;
|
a) le
fabricant de la drogue nouvelle a, relativement à celle-ci, déposé auprès du
ministre une présentation de drogue nouvelle, une présentation de drogue
nouvelle pour usage exceptionnel, une présentation abrégée de drogue nouvelle
ou une présentation abrégée de drogue nouvelle pour usage exceptionnel que
celui-ci juge acceptable;
|
(b) the Minister has issued, under
section C.08.004 or C.08.004.01, a notice of compliance to the manufacturer
of the new drug in respect of the submission; and
|
b) le
ministre a délivré au fabricant de la drogue nouvelle, en application des
articles C.08.004 ou C.08.004.01, un avis de conformité relativement à la
présentation;
|
(c) the notice of compliance in
respect of the submission has not been suspended under section C.08.006.
|
c) l’avis
de conformité relatif à la présentation n’a pas été suspendu aux termes de
l’article C.08.006.
|
(d) [Repealed, SOR/2014-158, s. 10]
|
d) [Abrogé,
DORS/2014-158, art. 10]
|
...
|
(…)
|
(2) A new drug submission shall
contain sufficient information and material to enable the Minister to assess
the safety and effectiveness of the new drug, including the following:
|
(2) La
présentation de drogue nouvelle doit contenir suffisamment de renseignements
et de matériel pour permettre au ministre d’évaluer l’innocuité et
l’efficacité de la drogue nouvelle, notamment :
|
…
|
(…)
|
It is clear that the ultimate purpose of the
Regulations is to establish the safety and effectiveness of a new drug
one wishes to sell or advertise in Canada. Not only does that transpire from
the Regulations, but the Supreme Court of Canada, in another case
involving omeprazole (but not omeprazole magnesium), commented that “(t)he FDA objective is to encourage bringing safe and
effective medicines to market to advance the nation’s health” (AstraZeneca
Canada Inc. v Canada (Minister of Health), 2006 SCC 49, [2006] 2 S.C.R. 560,
para 12).
[11]
If an innovator wishes to bring to market a new
drug, its submission must include, pursuant to C.08.002(1):
(g) detailed reports of the tests made to establish the safety of
the new drug for the purpose and under the conditions of use recommended;
(h) substantial evidence of the clinical effectiveness of the new
drug for the purpose and under the conditions recommended;
As Justice Layden-Stevenson noted in Reddy
Cheminor Inc.v Canada (Attorney General), 2003 FTC 542, 233 FTR 271, this
kind of information is typically voluminous; the evidence in that case
suggested that it could range from 100 to 300 volumes of data.
[12]
There is fortunately a less expensive route that
is made available in appropriate cases: the abbreviated new drug submission [or
ANDS]. If a manufacturer wishes to copy a marketed drug, as opposed to bringing
to market a completely new drug, it may avoid providing voluminous detailed
reports and data demonstrating the required safety and effectiveness. The Regulations
allow for a comparison with the Canadian reference product, a term defined
in the Regulations in the following fashion:
C.08.001.1 For the purposes of this
Division,
|
C.08.001.1 Les définitions qui suivent s’appliquent au présent titre.
|
Canadian reference product means
|
produit de référence canadien Selon le cas :
|
(a) a drug in respect of which a
notice of compliance is issued under section C.08.004 or C.08.004.01 and
which is marketed in Canada by the innovator of the drug,
|
a) une
drogue à l’égard de laquelle un avis de conformité a été délivré en
application des articles C.08.004 ou C.08.004.01 et qui est commercialisée au
Canada par son innovateur;
|
(b) a drug, acceptable to the
Minister, that can be used for the purpose of demonstrating bioequivalence
on the basis of pharmaceutical and, where applicable, bioavailability
characteristics, where a drug in respect of which a notice of compliance has
been issued under section C.08.004 or C.08.004.01 cannot be used for that
purpose because it is no longer marketed in Canada, or
|
b) une
drogue jugée acceptable par le ministre et qui peut être utilisée
pour la détermination de la bioéquivalence d’après les caractéristiques
pharmaceutiques et, le cas échéant, les caractéristiques en matière de
biodisponibilité, lorsqu’une drogue pour laquelle un avis de conformité a été
délivré en application des articles C.08.004 ou C.08.004.01 ne peut être
utilisée à cette fin parce qu’elle n’est plus commercialisée au Canada;
|
(c) a drug, acceptable to the
Minister, that can be used for the purpose of demonstrating bioequivalence on
the basis of pharmaceutical and, where applicable, bioavailability
characteristics, in comparison to a drug referred to in paragraph (a); (produit de référence canadien)
|
c) une
drogue jugée acceptable par le ministre qui peut être utilisée pour la
détermination de la bioéquivalence d’après les caractéristiques
pharmaceutiques et, le cas échéant, les caractéristiques en matière de
biodisponibilité, par comparaison à une drogue visée à l’alinéa a). (Canadian
reference product)
|
[my emphasis]
[13]
The brand name drug (it is typically the case)
marketed by the innovator is copied, and the “generic
drug” will receive a NOC as long as it satisfies the conditions
prescribed by the Regulations. It is C.08.002.1 that is particularly
relevant. I reproduce it in its entirety in view of its importance in this case:
C.08.002.1 (1) A manufacturer of a new drug may file an abbreviated new drug
submission or an abbreviated extraordinary use new drug submission for
the new drug where, in comparison with a Canadian reference product,
|
C.08.002.1 (1)
Le fabricant d’une
drogue nouvelle peut déposer à l’égard de celle-ci une présentation
abrégée de drogue nouvelle ou une présentation abrégée de drogue nouvelle
pour usage exceptionnel si, par comparaison à un produit de référence
canadien :
|
(a) the new drug is the pharmaceutical
equivalent of the Canadian reference product;
|
a) la
drogue nouvelle est un équivalent pharmaceutique du produit de
référence canadien;
|
(b) the new drug is bioequivalent
with the Canadian reference product, based on the pharmaceutical and, where
the Minister considers it necessary, bioavailability characteristics;
|
b) elle
est bioéquivalente au produit de référence canadien d’après les
caractéristiques pharmaceutiques et, si le ministre l’estime nécessaire,
d’après les caractéristiques en matière de biodisponibilité;
|
(c) the route of administration
of the new drug is the same as that of the Canadian reference product; and
|
c) la voie
d’administration de la drogue nouvelle est identique à celle du produit
de référence canadien;
|
(d) the conditions of use for
the new drug fall within the conditions of use for the Canadian reference
product.
|
d) les conditions
thérapeutiques relatives à la drogue nouvelle figurent parmi celles qui
s’appliquent au produit de référence canadien.
|
(2) An abbreviated new drug submission
or an abbreviated extraordinary use new drug submission shall contain
sufficient information and material to enable the Minister to assess the
safety and effectiveness of the new drug, including the following:
|
(2) La

|
(4) For the purposes of this section,
in the case of an abbreviated new drug submission, a new drug for
extraordinary use in respect of which a notice of compliance has been issued
under section C.08.004.01 is not a Canadian reference product.
|
(4)
Pour l’application du présent article, dans le cas d’une présentation abrégée

[my emphasis]

[je souligne]

[14]
The scheme of the Regulations appears to
be relatively straight forward. The goal is to have safe and effective
medicines; in order to achieve that goal the manufacturer may bring an ANDS if
the conditions are met, one of which being that the new drug is bioequivalent
with the Canadian reference product. As I read para C.08.002.1(1) and (2), this
is not a discretionary option. The goal is for medicines to be safe and
effective, and the way to get there passes through section C.08.002.1, which
includes bioequivalence. As I read the Regulations, those requirements
cannot be circumvented.
[15]
The Minister must therefore consider the
bioequivalence between the Canadian reference product and the new drug in its
generic version. If the generic product is bioequivalent to the reference
product, which has already been approved, then it should be acceptable despite
not providing “detailed reports of the tests made to
establish the safety of the new drug for the purpose and under the conditions
of use recommended” and “substantial evidence of
the clinical effectiveness of the new drug for the purpose and under the
conditions of use recommended” (para C.08.002 (2)(g) and (h)), which
undeniably constitutes a heavy burden. But bioequivalent it must be.
[16]
The quid pro quo is that the ANDS does
not include the voluminous information described at C.08.002(2)(g) and (h) as
seen at C.08.002.1(2)(a)(i). If the requirements of C.08.002.1 are
satisfied by a generic manufacturer, it will not have to present the extensive
evidence that was required of the innovator. Pursuant to subsection
C.08.004(1), the Minister must issue a NOC if the ANDS complies with subsection
C.08.002.1 as set out above. The NOC that would be issued in those
circumstances “shall constitute a declaration of
equivalence for that new drug” (C.08.004(4)).
[17]
The ANDS is submitted to the Therapeutic
Products Directorate [or TPD] at Health Canada. It is naturally the Minister of
Health who has the authority to issue the NOC; this authority is typically
delegated to the Director General of the TPD.
III.
Context
[18]
It is helpful to put this case in its broader
context before considering further the mechanism of “reconsideration”
that is the subject of the challenge in this case.
[19]
The NOC sought by Apotex in the early 2000’s had
received a positive reception from Health Canada. On March 7, 2003, Health Canada
wrote to Apotex to confirm that the examination of the ANDS for Apo-Omeprazole
(Omeprazole magnesium) was completed. It is not disputed that this signalled a
positive examination, but the final determination could not be communicated in
view of the fact that there was a patent in place.
[20]
On December 5, 2008, Apotex was advised that its
ANDS was not “approvable at this time”. The
reason for the position change was that the earlier decision was based on the
ingestion of the tablet in circumstances where the person was fasting (OMEC14)
and where the meal was low in fat and calories (OMEC13 and OMEC16). It appears
that with greater experience with this kind of medication, Health Canada came
to the realization that submissions had to include the full spectrum, from
fasted to standard fed conditions. That includes not only low fat/low calorie
meals, but also high fat meals. Thus, the satisfaction of the bioequivalence
requirement needed evidence under both fasted and standard fed conditions,
which the ANDS did not provide.
[21]
The letter went on to request that Apotex submit
a high fat fed pharmacokinetic study, or a high fat fed pharmacodynamics study
in patients or any other scientific rationale with data that would support
evidence of bioequivalence. Given the delay in reaching a negative conclusion,
Health Canada offered its assistance in discussing an appropriate study design
and committed to quickly consider the evidence in the context of the entirety
of the submission and to perform an expeditious review in order to decide on
the disposition of the submission.
[22]
Two things appeared to be very clear. Health
Canada was insisting on bioequivalence and evidence of bioequivalence had to be
under both fasted and high fat fed conditions. We now know that Apotex never produced
satisfactory evidence of bioequivalence under high fat fed conditions in its
initial ANDS.
[23]
Non-compliance was found by the Minister and
reconsideration was denied. Apotex challenged on judicial review more than a
year later. Apotex sought to argue before this Court that it was entitled to
its NOC because it claimed that it had acquired a vested right. In Apotex
Inc. v Canada (Health), 2011 FC 1308; 400 FTR 28, my colleague Justice
Robert Barnes reported that following the December 5, 2008, letter, the
Minister issued a notice of non-compliance withdrawal letter for Apo-Omeprazole
Tablets. A request for reconsideration of the decision to issue the Notice of
Non-Compliance was also denied, this time on July 28, 2009. The Challenge to
the three “decisions” was brought on August 26,
2010. Apotex had argued that the “decisions”
were “unlawful, unreasonable, unfair, discriminatory,
illogical, scientifically untenable and biased” (para 14). Barnes J.
concluded that the application was out of time. Nevertheless, my colleague
considered if Apotex had a vested right in view of the March 7, letter. If
there is a vested right to a NOC, arguably there may be an entitlement to bring
judicial review at any time to enforce the vested right. He concluded:
[33] It seems
quite obvious to me that until a NOC is issued, a proponent enjoys no vested
interest in a favourable outcome at least with respect to issues that properly
fall within the Minister’s lawful discretion (ie. pertaining to public safety
and efficacy). There is no legal significance attaching to an application for
a NOC that has been placed on patent hold. The Minister is fully entitled to
revisit scientific issues at any point in the process up to the actual issuance
of a NOC. It is only at that point that the Minister’s examination is
completed in accordance with C.08.004 of the Food and Drug Regulations,
RSC 1985, c F-27.
[24]
Apotex appealed (2012 FCA 322; 443 NR 291). The
Federal Court of Appeal agreed with the Federal Court that Apotex’s application
was out of time. Furthermore, the Court rejected the argument that the Minister
is compelled to issue a NOC once Apotex was notified that the submission was
satisfactory, at the time, for the purpose of the Regulations. The
purpose of the Act and the Regulations being to bring safe and effective
medicines to market, the Court of Appeal found that it would be absurd to “construe the Regulations in such a way that the Minister
could be compelled to issue a NOC even if she was not satisfied that the drug
in question is safe and effective” (para 30). Moreover, the Court of
Appeal did not accept that Apotex had a legitimate expectation that the NOC
would be issued once the patent hold was over: the legitimate expectation
doctrine does not confer substantive rights of the nature sought.
[25]
As can be seen, the Federal Court of Appeal was
insistent that the safety and effectiveness of the drug was the governing
principle. The Minister was entitled to come to the conclusion that more was
needed in order to be satisfied of the safety and effectiveness. That in effect
was the long and short of it. The concerns about safety and efficacy were found
to be bona fide:
[44] Before
leaving this point, I have considered Apotex’ submission that it was “unfair
and arbitrary” for the Minister’s officials to prefer the negative result of a
2008 review of its submission over the positive result obtained in 2002 when,
it alleges, there had been no material change in circumstances. I have also
considered its argument that the conduct of the Minister’s officials gives rise
to a reasonable apprehension of bias.
[45] Apotex’ evidence on these points was
addressed by the Minister.
[46] On the
whole of the evidence I find that Apotex has failed to establish that the
Minister’s safety and efficacy concerns were not bona fide. The evidence
is consistent with there being significant uncertainty within the Therapeutic
Products Directorate of Health Canada about the appropriate bioequivalence
requirements to be applied to proton pump inhibitors. Such scientific
uncertainty does not detract from the bona fides of the Minister’s
safety and efficacy concerns.
[26]
While Health Canada was steadfast that
bioequivalence had to be established on the full spectrum (from fasting to high
fat fed meals) in order to be satisfied that the drug is bioequivalent, and
thus was safe and effective, it was also willing to assist in creating a study
that could prove to be appropriate. It stated plainly that any other scientific
rationale with data that would support evidence of bioequivalence would be
received. The data thus produced would be reviewed expeditiously. Obviously,
nothing happened and OMEC03 was not produced. A Notice of Non-Compliance
Withdrawal Letter with respect to that first submission was issued and, as
noted by Barnes J., reconsideration was denied on July 27, 2009. It took more
than a year to apply to this Court on judicial review, which was found to be
fatal in and of itself. Moreover, the two federal courts commented on the
ability of the Minister to seek more information to ascertain bioequivalence.
[27]
Finally, on February 4, 2013, Apotex refiled its
ANDS; this time it included the 1998 fed study with a high fat meal, the OMEC03
study, after it sought to offer a study that was found to be inadequate. It was
not successful and notice of non-compliance was issued on November 28, 2013.
[28]
In the end, the various chapters in this
particular episode boil down to this. Apotex was on its way to approval for its
Apo-Omeprazole Tablets on March 7, 2003, on the basis of studies that did not
include high fat/high calorie meals. However, the regulator concluded on
December 5, 2008, that approval could not be given because bioequivalence was
not demonstrated: evidence of bioequivalence under both fasted and standard fed
conditions was found to be necessary. Instead of providing the evidence of
bioequivalence, Apotex chose to challenge the decision arguing that rights had
vested; it was unsuccessful before this Court and the Federal Court of Appeal.
Apotex ultimately submitted its 15-year old OMEC03 study as its only study
meant to satisfy the concerns about bioequivalence.
[29]
The Notice of Non-Compliance of November 28,
2013, is explicit that not only the standards to determine bioequivalence
between Apotex’s new drug and the Canadian reference product under high fat fed
conditions were not met, but equally important Health Canada complained that
the test meal (760 calories instead of the required 1000) was not a standard
high calorie/high fat meal; indeed, the sampling protocol was not adequate, the
study was not adequately powered and three enteric-coated tablets were
administered instead of only one. The letter offers precise guidance concerning
what would be required in the design and implantation of a new study. There was
no new study and there has not been a new one.
IV.
Reconsideration
[30]
Instead of devising a new study with a view to
satisfy Health Canada’s requirement that there be bioequivalence under high
fat/high calorie fed meal or challenging the refusal on judicial review, Apotex
chose to seek “reconsideration”.
[31]
As the document “Guidance
for Industry – Reconsideration of Final Decisions Issued for Human Drug
Submissions” states, Health Canada has put in place a policy the
purpose of which is to resolve drug submission-related disputes; it applies to
ANDS.
[32]
If the Minister issues a notice of
non-compliance withdrawal for a drug submission, the sponsor can request a
reconsideration process described in a policy document.
[33]
The Guiding Principles for Dispute Resolution
require staff to “resolve disputes in a fair and timely
manner, using the most appropriate dispute resolution mechanism.” The
principles are fairness, accountability, and accessibility. The reconsideration
process is a formal dispute resolution mechanism and is intended to be used
when informal dispute resolution mechanisms have failed.
[34]
The sponsor files the request for
reconsideration and the Office of Science recommends to the Director General of
the Therapeutic Products Directorate a process to be followed to address the
reconsideration request, which could include referring the issues to an
external panel, reviewing the issues within the Office of Science, or a
combination.
[35]
The Director General decides what process to
follow and informs the sponsor. Here, the matter was to be handled by a
reconsideration panel. Its composition is determined by the sponsor (Apotex)
and by the affected Directorate (Therapeutic Products Directorate) each
recommending a panel member with the Director General appointing the panel’s
chair.
[36]
The more difficult issue may well be the
determination of the parameters, or mandate, of the Reconsideration Panel. In
this case, Apotex and the Director General were incapable to reach an agreement
on the question to be posed to the Panel, which led to the cancellation of the process
on November 16, 2015. That constitutes the only decision which is the subject
of the judicial review.
[37]
The Reconsideration Policy does not detail how
the sponsor and Health Canada are to agree on the question put to the
Reconsideration Panel. The Policy simply states that “the
Office [of Science] will work with the sponsor and the review bureau/centre to
draft specific questions to be posed” to the Scientific Advisory
Committee or the Panel. However, the Policy provides clear indications of the
type of issues that could go to a reconsideration panel. Thus, the Policy lists
examples of issues that are generally appropriate for referral to an external
panel:
- interpretation
of available data;
- disagreement
in applied methodology; and
- relative weights given to data
impacting on the risk/benefit assessment of the submission information.
The Policy also indicates what issues are
generally inappropriate for referral to an external panel:
- submission
of false information;
- allegations of bias;
- matters
in which regulatory policy/guidance or procedures are the dominant concern; and
- an
issue on which the Directorate has available recent external independent expert
opinion.
[38]
Obviously, the Policy contemplates issues of a
technical nature. Matters of regulatory policy or procedure are not
contemplated. Furthermore, the Policy is focused on discrete issues to be
brought before the Panel whose role is purely advisory:
The roles and
responsibilities of the Panel, and the process for obtaining its advice
will be the same as for the SAC outlined in Section 5.3.1(a). Consistent with
its advisory role, the Panel will not be asked to make a decision on the
submission; rather, advice will be solicited through one or more direct
questions related to the specific outstanding issue(s) identified.
[my
emphasis]
(Policy, 5.1.3(b) Reconsideration Panel)
[39]
I fail to see how that process can be understood
to suggest that it constitutes, for all intents and purpose, an appeal of
sorts. It is rather a process put in place to address discrete issues of a
technical nature where the Director General of the Therapeutic Products
Directorate plays a central role. She appoints the panel chair; she will receive
the advice of a panel; she will make the reconsideration decision. The Panel
members have expertise relevant to the resolution of the matter raised, not on
matters of regulatory guidance or procedure. Issues around data, methodology
and weight to be given to data impacting on the risk/benefit assessment are
apposite. Are not matters in which regulatory policy or procedures are the
dominant concern.
[40]
In a sense, the Director General is not wrong to
say that it is her process: she makes the final reconsideration decision and
the advice is for her. She may also refuse a reconsideration filed for
decisions that are not eligible. Indeed, her role is defined in the following
fashion in the Policy:
The Director
General of TPD or BGTD or his/her designate is responsible for:
• refusing Reconsiderations filed for decisions that are not
eligible;
• deciding whether to consider information filed in the
Request of Reconsideration;
• deciding on the process for the disposition of the Request
for Reconsideration;
• deciding on the use and membership of the Scientific
Advisory Committee or Reconsideration Panel (if applicable); and
• making the Reconsideration decision.
(Policy, 4. Roles and Responsibilities)
Obviously, a director general who would not
be acting in good faith or would display bias, for instance, may well attract scrutiny
on judicial review despite the high degree of discretion reposed in her.
Fairness commands no less. But there is no such allegation here.
[41]
I have not found any indication suggesting that
the sponsor has an unhampered ability to raise whatever issue it sees fit. In
fact, it is quite the opposite. Issues that may be ripe for reconsideration
appear rather to be of a particular ilk. That may well be why the Policy
requires that the Drug Submission sponsor work with the Office of Science in
the Therapeutic Products Directorate to draft questions to be posed to the
Reconsideration Panel. Contrary to what Apotex asserted, the reconsideration
process is not adversarial with the Panel as a judge of the matter raised by a
sponsor. It is rather a process where experts in a field will provide advice to
a Director General on discrete issues that have been identified in questions
agreed to by the sponsor and Office of Science of the TPD. It is a way to avoid
disputes: as stated in the Policy, “(i)f, at any time
during the Reconsideration process, the sponsor files a Notice of Application
to the Federal Court to resolve the matter, the Directorate will terminate the
Reconsideration process”. That reconsideration process resulted in an
impasse in this case. While Apotex insisted that the question to be posed to
the Reconsideration Panel had to turn on whether its new drug is safe and
effective, the Therapeutic Products Directorate was of the view that the focus
of the question had to be on bioequivalence.
V.
The reconsideration process: the Question
[42]
Apo-Omeprazole belongs to a class of drugs
termed “proton pump inhibitors” or “PPIs”. PPIs inhibit gastric acid production to
address problems such as ulcers. PPIs are unstable in acidic conditions;
therefore, they are made with an enteric coating for protection in the stomach
so they can pass into the intestine where they are absorbed into the body. The
Canadian reference product for the Apo-Omeprazole ANDS is “Losec”, which has no restrictions on what food it can
be taken with.
[43]
The Notice of Non-compliance of November 28,
2013, was based on the conclusion that the new drug did not comply with section
C.08.002.1 of the Regulations, which requires that the new drug be
bioequivalent with the Canadian reference product. The letter of November 2013
states:
In order to
demonstrate the safety and effectiveness of Apo-Omeprazole (omeprazole
magnesium) delayed release tablets, there is a requirement to demonstrate
bioequivalence with the Canadian reference product under both fasting and high
fat fed conditions. […]
The standards to determine bioequivalence
under single dose high fat fed conditions…were not met by Study OMEC03.
Furthermore, there were numerous design
issues with the study including: the test meal was not a standard high calorie,
high fat meal; the sampling protocol was not adequate to define the drug
concentration-time profiles; the study was not adequately powered; and three
enteric coated tablets were administered when only one was required, likely
contributing to the multiple peak concentration-time profiles that were seen.
The decision to recommend a Notice of
Non-Compliance for this submission was based on the totality of the data that
has been provided…
In order to demonstrate the safety and
efficacy of your product, please provide data from an appropriately designed
and executed comparative bioavailability study conducted under high fat, high
calorie fed conditions…
[44]
The NON also lists comments that should be taken
into consideration by the applicant before designing and implementing a new
study, including using a standard high calorie, high fat meal of 1000 calories
with 50% or 500-600 calories derived from fat (2 eggs fried in butter, 2 strips
of bacon, 2 slices of toast with butter, 120 grams of hash browns, 240
millilitres of whole milk). The test meal in OMEC03 was 760 calories, with 53%
(405 calories) derived from fat.
[45]
That set the stage for what was to follow.
Apotex responded to the NON in January 2014 stating that the submitted studies
were sufficient to establish the safety and effectiveness of the product. I
note that Apotex relies on the safety and effectiveness of its product while
the Minister speaks of the requirement to establish bioequivalence. There is a
difference. The company did not submit a new study. Apotex’s response to the
NON’s primary objection that OMEC03 did not meet the standards to determine
bioequivalence was three-fold:
•
TPD approved the earlier version of the ANDS for
the same drug in 2003 and accepted the low fat “fed”
study submitted at that time;
•
TPD’s approval of other PPI products shows there
is no therapeutic relevance to TPD’s alleged deficiencies with the OMEC03
study; and
•
Since numerous omeprazole and omeprazole
magnesium products that are not bioequivalent to each other have all been approved
by TPD and are interchangeable, strictly meeting the standards in the 2012
bioequivalence guidelines with respect to one CRP is not relevant to safety,
effectiveness, or interchangeability.
[46]
Fundamentally, the Minister required
bioequivalence because the law requires it, while Apotex wanted its new drug to
be found safe and effective in spite of a lack of evidence that there was
bioequivalence when the tablet is used on a high fat/high calorie meal. Apotex
seemed to argue that it should have received the NOC on the basis of the 2003
studies, that OMEC03 is good enough, and that it is discriminated against
because other products have not been given de same level of scrutiny.
[47]
The Notice of Non-compliance Withdrawal letter
of July 28, 2014, made essentially the same points as the notice of
non-compliance:
The high fat study
OMEC03 that was submitted under Control Number 162270 to satisfy the criterion
of demonstrating bioequivalence under high fat/high calorie fed conditions,
failed to meet bioequivalence criteria as the 90% confidence interval of the
relative mean AUCt is outside of the acceptance range of 80-125%. Furthermore,
the results of the study were not meaningful due to poor study design and no
useful information could be obtained in regard to the performance of the
enteric coat of the delayed release tablet under high fat/high calorie fed
conditions.
A study conducted under high fat/high
calorie fed conditions that, at a minimum, produces reliable evidence is
required to demonstrate the performance of Apo-Omeprazole (omeprazole
magnesium) delayed release tablets relative to the CRP. This study will provide
necessary evidence of the safety and efficacy of the test product under the
extremes of the conditions of use that will be realized in patients. This
requirement has been met by all other generic Proton Pump Inhibitor (PPI)
products that are approved in Canada. The requirement to demonstrate
bioequivalence to the CRP in a high fat/high calorie fed study has been
established through industry and scientific experts as evidenced by the
findings of the Expert Advisory Committee on Bioavailability and Bioequivalence
(EAC-BB, now the Scientific Advisory Committee-BB or SAC-BB) and is furthermore
an internationally accepted practice.
[48]
The battle lines were drawn. In June 2015,
Apotex submitted its Request for Reconsideration package, which says that the contentious
issue is whether the entire submission, including all of the bioavailability
study data, the nature of the therapy, the approval of other products and other
factors sufficed to establish the safety and efficacy of Apo-Omeprazole. Health
Canada’s Bureau of Pharmaceutical Sciences, on the other hand, sought to focus
the question for the Reconsideration Panel on bioequivalence, and specifically
whether OMEC03 provided reliable evidence of bioequivalence under fed
conditions. What followed is an exchange of correspondence about suggested
questions that never even attempted to bridge the divide. I have underlined the
essential ingredient of each question.
[49]
On September 18, 2015, both parties submitted
their proposed questions for the panel:
•
Apotex proposal: Based on all available
information, including the approval of other PPI’s, does the submitted
information reasonably suffice for a conclusion that Apo-Omeprazole Tablets are
safe and effective and thus also entitled to an NOC?
•
Bureau proposal: Does the data from study OMEC03
suffice to demonstrate the relative performance of Apo-Omeprazole (omeprazole
magnesium) tablets under high fat/high calorie fed conditions to the Canadian
reference product in order to make a regulatory determination of
bioequivalence?
[50]
The Office of Science reviewed both drafts and
prepared the following question:
Have
Apo-Omeprazole (omeprazole magnesium) enteric coated tablets been demonstrated
to be bioequivalent to the Canadian reference product, under fed
conditions?
[51]
On October 5, 2015, Duane Terrill from Apotex
wrote to Health Canada rejecting the proposed question from the Office of
Science:
The question that
we submitted is whether or not the submitted information suffices for a
conclusion that the product is safe and effective. This is clearly
the one and only relevant question.
Your proposed question is whether or not the
product has “been demonstrated to be bioequivalent to the Canadian reference
product, under fed conditions?”
That question is ambiguous. The answer
depends on the definition of “bioequivalent under fed conditions”. The question
can be interpreted as presuming that it is mandatory to fully meet, with a high
fat meal, the criteria in the latest version of the guideline. If that
presumption is made, the question becomes pointless, as we do not dispute that
the answer would be “no” based on that interpretation of the question.
There was nothing ambiguous in the suggested
question posed by Health Canada and, in the context, it is certainly not more
ambiguous than whether or not the product is safe and effective. The question
simply asks if Apotex’s product is bioequivalent under fed conditions. That
leaves much room for the Reconsideration Panel to opine on the central notion
of bioequivalence under fed conditions. There needed to be bioequivalence and,
in the view of the Minister, there was the requirement that it also be under
fed conditions at least since December 2008. As a matter of fact, Health Canada
staff responded on October 9, 2015, indicating that they were not going to
change the question because “bioequivalence is one of
the four pre-conditions in order to obtain an ANDS.” I would have
thought that C.08.002.1 makes the requirement of bioequivalence amply clear. That
would be the essential rationale for Health Canada to refuse questions where
the issue would be to seek advice on whether the new drug is safe and effective
in spite of the fact that the high fat/high calorie test failed.
[52]
Mr. Terrill responded on October 13, 2015, with
an amended question:
Does the available
information, including the submitted bioequivalence studies, reasonably suffice
to conclude that Apo-Omeprazole tablets are safe and effective?
[53]
In that email of October 13, 2015, Mr. Terrill
would tend to demonstrate that Apotex was sticking to its contention that the
Reconsideration Panel had to review the product for its safety and
effectiveness, whether there is bioequivalence or not:
With respect to (a), the issue highlighted
in our Request for Consideration is NOT whether or not Apotex submitted a
bioequivalence study with a high fat meal meeting the confidence criteria in
the guideline. We do not deny that same was not done, so whether or not it was
done cannot be what is at issue. The issue raised is whether or not, despite
our not having provided such a study, the available information suffices to
adequately demonstrate safety and effectiveness, to at least the same extent as
other approved products.
The Director General has agreed that our
Request for Reconsideration will go to a panel. It follows that the question
cannot be whether or not we submitted a study fully meeting the purported
criteria (we agree that we did not). But must be whether or not what was
submitted nevertheless reasonably suffices to demonstrate safety and
effectiveness.
[underlined
in the original]
I note that in that same email, Mr. Terrill
introduces the notion of meeting criteria in the guideline:
1. As we explained, your proposed
question is unacceptable by reason of being ambiguous, in that “bioequivalence”
must be established in the fed state specifically, and presumably also to meet
criteria in a guideline. If the Panel interprets the question in that way, the
Panel’s work would be improperly constrained.
Mr. Terrill speaks of “presumably”. His speculation is not supported by any
evidence that I could find on this record. In the exchanges, the respondent has
been consistent that her position has been, and still is, that bioequivalence
is that which is referred to in the Regulations, nothing else. Strict
adherence to criteria has never been a requirement. Mr. Terrill’s presumption
is not based on the evidence I have been able to review.
[54]
The Director General responded with a letter to
Apotex on October 27, 2015 (the Reconsideration Panel members are copied on the
letter; the Reconsideration Panel was to meet on October 30, 2015), explaining
why she could not agree with Apotex’s latest proposed question. She said that
the only scientific issue in the NONW letter was “whether
the results of the high-fat study provide accurate estimates of AUCt and Cmax
relative to the Canadian reference product.” She added that it is not
the panel’s role to interpret regulations or recommend a product’s approval,
but rather to review the scientific issues upon which a negative decision on
the drug submission was issued. She proposed yet another question:
Do the results
from study OMEC03 provide reliable evidence of the bioavailability characteristics
of Apo-omeprazole delayed release tablets in order to assess safety and
effectiveness through bioequivalence with the Canadian reference product as
required in C.08.002.1(2) of the Food and Drug Regulations?
[55]
On October 28, 2015, Mr. Terrill again rejected
Health Canada’s proposed question, arguing that such a narrowing of the issue
constituted fettering of discretion in that it premised the review on the need
for a high fat meal meeting confidence criteria in the bioequivalence
guidelines. Mr. Terrill also asked that the panel be permitted to identify
missed opportunities for early dispute resolution and that Apotex be given 2
hours to present to the panel instead of the allotted 45 minutes.
[56]
It is not easy to understand how referring
directly to the provision in the Regulations which calls for “sufficient information and material to enable the Minister
to assess the safety and effectiveness of the new drug” constitutes a
fettering of discretion. Nevertheless, that is the position advanced.
[57]
On November 6, 2015, the Director General wrote
back to Apotex proposing another version of the question that allowed for
consideration of the entire submission. She stated that if this approach was
unacceptable, she would consider the reconsideration request withdrawn and
declare the NONW final. Her final proposed question was:
Do the results
from study OMEC03, examined as part of the totality of evidence contained in
this Abbreviated New Drug Submission, provide reliable evidence of the
bioavailability characteristics of Apo-omeprazole delayed release tablets in
order to assess safety and effectiveness through bioequivalence with the
Canadian reference product as required in C.08.002.1(2) of the Food and Drug
Regulations? Why or why not?
Again, the reference to subsection
C.08.002.1(2) must be concerning the requirement that the ANDS addresses the
requirement of bioequivalence. Two days later, Apotex reiterated the same
position.
[58]
Hence, on November 16, 2015, the Director
General wrote to Apotex that it was cancelling the reconsideration and
finalizing the NONW that had been issued on July 28, 2014. The relevant part of
the decision states:
You disagree with
the question I have proposed for the reconsideration panel, and despite my
comment that I am prepared to be somewhat flexible, you did not provide an
alternative. The question that I have posed in the November 6, 2015 letter is
not a fettering of my discretion as you claim, but is an approach in line with
assessing whether the regulatory requirement C.08.002.1(2) of the Food and Drug
Regulations has been met.
You also continue to request that the scope
of the panel be expanded to deal with your objections to the process itself,
which I take to mean going back to revisit your company’s previous submissions.
This is not the purpose of a reconsideration. A reconsideration panel is put
together to provide expert analysis and advice on a scientific question, and
not to address information or issues that were not expressed in the negative
decision letter.
Since we remain at an impasse, and as I
indicated in my letter of November 6, 2015, the reconsideration of this
submission, control number 162270 is cancelled and the Notice of
Non-Compliance-Withdrawal issued on July 28, 2014 is now final.
[59]
That is the “decision”
that Apotex would want to see judicially reviewed.
VI.
Issues and analysis
[60]
The applicant challenges the decision made by
the Director General to cancel the reconsideration of Apotex’s submission in
respect of its Omeprazole Magnesium Tablets. The AND submission is treated as
withdrawn. It is not disputed that the Director General is the Minister of
Health’s delegate for the purpose of the decision made.
[61]
As shown in the preceding section, Apotex argued
that the reconsideration exercise ought to be about whether or not its new drug
is safe and effective; the Minister contends that the manufacturer of a new
drug, according to section C.08.002.1 of the Regulations, may file an
AND submission that compares the Canadian reference product, such that the new
drug is bioequivalent, based on the pharmaceutical and, when the Minister
considers it necessary, bioavailability characteristics.
A.
Arguments
[62]
Fundamentally, Apotex’s argument is that the
Minister fettered her discretion in deciding that the reconsideration exercise
had to focus on bioequivalence instead of allowing it to establish safety and
efficacy (memorandum of fact and law, paras 3, 5, 24, 39, 47, 48, 53). The
whole focus of Apotex has been, both in its evidence and in its memorandum of
fact and law, that it would rather argue its case on the basis that its new
drug is safe and effective, thus avoiding as much as possible the
bioequivalence step. Although it met requirements under low fat/low calorie
meals and the absorption of its tablets on an empty stomach, its 1998 study
using a high fat/high calorie meal was only submitted fifteen years later,
after a trip to the Federal Courts to argue unsuccessfully that it had gained a
vested right to a NOC without evidence about a fat fed meal. The applicant has
conceded in its memorandum of fact and law that “in
relation to the “fed” study, the criteria were not met by its ANDS”
(para 56). Apotex’s solution was to avoid the high fat/high calorie meal to
show the Reconsideration Panel that its new drug is safe and effective.
[63]
While not pointing to anything in the evidence
to support the argument, Mr. Terrill, for Apotex, claims that the Minister also
fettered her discretion in insisting that the question be about strict
compliance with the bioequivalence criteria that are found in the guidelines.
[64]
The applicant includes in its “fettering” argument that other products that would
not meet strict compliance with bioequivalence were approved in the past.
[65]
Apotex also offered an argument about its
legitimate expectations being defeated: the Minister had created expectations
that she would follow a procedure that included working with a sponsor to draft
the questions to be posed to the Reconsideration Panel that would address the
issues in dispute. The applicant seems to go as far as suggesting that the
issues it raised are to go to the Reconsideration Panel (memorandum of fact and
law, para 90). Such was its expectation.
[66]
The Minister denies that discretion was fettered
in any way. She followed the Regulations that control in the circumstances.
[67]
These Regulations provide for a more
expeditious pathway when a manufacturer wishes to copy a drug that has already
received a NOC. Detailed reports of the tests made to establish the safety of
the new drug are not required; nor is there the necessity of substantial
evidence of clinical effectiveness of that new drug. That has been already
established with respect to the Canadian reference product.
[68]
However, the Regulations have some
requirements for the new drug to compare with the Canadian reference product.
In order to compare, to be able to use the expeditious pathway, the AND
submission filed deals with:
•
the new drug is the pharmaceutical equivalent;
•
the new drug is bioequivalent;
•
the route of administration of the new drug is
the same;
•
the conditions of use fall within those for the
Canadian reference product.
As the Minister points out,
C.08.002.1(2)(c)(i) states unequivocally that the ANDS “shall
contain sufficient information and material to unable the Minister to assess
the safety and effectiveness of the new drug, including the following … (c)
evidence from the comparative studies conducted in connection with the
submission that the new drug is … (i) the pharmaceutical equivalent of the
Canadian reference product.” It is the presence of pharmaceutical
equivalence and bioequivalence to the Canadian reference product that allows
for the extrapolation to the generic drug of the safety and effectiveness already
demonstrated by the Canadian reference product through detailed reports to
establish the safety and substantial evidence of the clinical effectiveness.
[69]
It is at the price of satisfying the prescribed
conditions, including pharmaceutical equivalence and bioequivalence, but
without having to present “detailed reports” and
“substantial evidence”, that the NOC will issue.
[70]
The Minister says that the guidelines published
by Health Canada (Conduct and Analysis of Comparative Bioavailability Studies
and Comparative Bioavailability Standards: Formulations Used for Systemic, May
2012) are purely for the assistance of the industry. They have been created
following consultations with the industry and they are explicit that they are
guidance documents. Alternate approaches are possible. They provide:
Guidance documents
are meant to provide assistance to industry and health care professionals on
how to comply with governing statutes and regulations. Guidance documents also
provide assistance to staff on how Health Canada mandates and objectives should
be implemented in a manner that is fair, consistent and effective.
Guidance documents
are administrative documents not having the force of law and, as such, allow
for flexibility in approach. Alternate approaches to the principles and
practices described in this document may be acceptable provided they are
supported by adequate justification. Alternate approaches should be discussed
in advance with the relevant program area to avoid the possible finding that
applicable statutory or regulatory requirements have not been met.
[71]
The Minister asserts that the ANDS does not
comply with the requirements of C.08.002.1 of the Regulations: the
evidence was simply not sufficient to establish that the new drug is
bioequivalent. It is not only that the standards to determine bioequivalence
were not met; there were also numerous design issues with the study “such that no useful information could be obtained in regard
to the performance of the enteric-coat of the Apo-Omeprazole delayed release
tablet under high fat fed conditions”, in the words of Dr. Scott Appleton
of the Bureau of Pharmaceutical Sciences, in the TPD, in his comprehensive
report of July 23, 2014. The Notice of Non-Compliance Withdrawal Letter
followed shortly thereafter (July 28, 2014). With such deficient data, it was
insufficient to meet the requirement for bioequivalence.
[72]
The need for a high fat/high calorie meal, which
emerged after the initial acceptance of Apotex’s submission with such study in
2003, after gaining experience with similar products, was explained by Dr.
Appleton:
The rationale for
testing or challenging an enteric coated tablet with food is that a meal delays
the emptying of the stomach’s contents into the small intestine (gastric
emptying). The rate of gastric emptying of any meal can be predicted by its
volume and nutrient density. Nutrient density is sensed mainly in the small
intestine where receptors feed information (nervous and endocrine signals) back
to the stomach to delay emptying by altering the patterns of gastric motility.
The presence of fat in the small intestine is the most potent inhibitor of
gastric emptying.
Therefore, a key
element of the design of a fed bioequivalence study is the selection of the
meal that will be given to volunteers prior to administration of the test and
reference products. It is clear that the type of meal that is administered to
volunteers in a fed bioequivalence study can greatly affect the outcome and the
utility of the study as follows:
A meal that is high in fat and
calories will provide maximal evidence as to how the enteric coating of a
delayed release tablet will behave when exposed to an acidic environment for an
extended period of time as it would be in the stomach of a patient who took the
product after a large meal.
Additionally, it has been suggested
that the pH of the stomach may not be uniform after a meal and the enteric coated
tablet could be exposed to regions of higher PH which could break down the
coating, resulting in the premature release of the drug.
A high fat meal may result in the
tablet becoming coated in fat or a fatty emulsion resulting from the meal,
which can affect the release of the drug from the tablet.
A meal that is low in fat and in
calories will not challenge the enteric coat of the tablet to the same extent
that a high fat/high calorie meal will.
Although it is referred to as one of the
“extremes” of the conditions under which a tablet might be taken (the fasting
state being the other “extreme”), a standard high fat/high calorie meal is a
meal that one would reasonably expect that a person might have for breakfast (e.g.
2 eggs fried in butter, 2 strips of bacon, 2 slices of toast with butter, 120
grams of hash browns and 240 millilitres of whole milk).
A fed bioequivalence study in which a high
fat/high calorie meal (>50% of calories from fat, as shown above) is
administered will serve (in conjunction with the required bioequivalence study
under fasting conditions) to maximally challenge the enteric coat of the
enteric coated tablet. In doing so, it will provide confidence that the enteric
coated product will perform in a manner similar to the CRP under all of the
conditions of use (that is in the range of fed states from fasted to high
fat/high calorie fed).
[73]
What is more, the Notice of Non-Compliance
Withdrawal Letter of July 28, 2014 provides the explanation for the conclusion
reached and confirms that all generic Proton Pump Inhibitors approved have met
the requirement:
The high fat study
OMEC03 that was submitted under Control Number 162270 to satisfy the criterion
of demonstrating bioequivalence under high fat/high calorie fed conditions,
failed to meet bioequivalence criteria as the 90% confidence interval of the
relative mean AUCt is outside of the acceptance range of 80-125%. Furthermore,
the results of the study were not meaningful due to poor study design and no
useful information could be obtained in regard to the performance of the
enteric coat of the delayed release tablet under high fat/high calories fed
conditions.
A study conducted under
high fat/high calorie fed conditions that, at a minimum, produces reliable evidence
is required to demonstrate the performance of Apo-Omeprazole (omeprazole
magnesium) delayed release tablets relative to the CRP [Canadian reference product].
This study will provide necessary evidence of the safety and efficacy of the
test product under the extremes of the conditions of use that will be realized
in patients. This requirement has been met by all other generic Proton Pump
Inhibitor (PRI) products that are approved in Canada. The requirement to
demonstrate bioequivalence to the CRP in a high fat/high calorie fed study has
been established through industry and scientific experts as evidenced by the
findings of the Expert Advisory Committee on Bioavailability and Bioequivalence
(EAC-BB, now the Scientific Advisory Committee-BB or SAC-BB) and is furthermore
an internationally accepted practice.
[74]
As for the reconsideration process, the
Minister’s position is that bioequivalence is a regulatory pre-condition.
Accordingly, the question to a reconsideration panel in this case would have to
be whether the study submitted could provide reliable evidence to assess bioequivalence,
as must be done under C.08.002.1(1) and (2) of the Regulations. The
Minister did not ask whether the applicant had complied with the guidelines;
rather the issue put in the proposed questions relates to the presence of
reliable evidence to satisfy the bioequivalence with the Canadian reference
product. In effect, the Minister insisted that the decision on safety and
effectiveness passes through bioequivalence while Apotex sought to circumvent
the requirement. The position is encapsulated in the following passage from the
last attempt made by the Director General at explaining the position:
From Health
Canada’s perspective, the only issue under dispute for this submission is what
was outlined in the Notice of Non-Compliance – Withdrawal (NON-W) letter of
July 28, 2014, and reiterated in my letter of October 27, 2015 – namely, the
interpretations of the results from study OMEC03 and integration of these
results with the other results you have submitted for this product. As such,
while I am prepared to be flexible with the framing of the question, in order
to satisfy the regulatory requirement for this abbreviated new drug submission,
the question must lead the Panel to make a recommendation on whether study
OMEC03 substantiates bioequivalence of your product with the Canadian Reference
Product.
….
Generic drugs, which are reviewed through an
Abbreviated New Drug Submission, must establish bioequivalence with the
Canadian Reference Product. It is through establishing bioequivalence that a
generic drug demonstrates safety and effectiveness. While a drug may be deemed
to be safe and effective, it cannot be assumed to also be bioequivalent. The
latter characteristic is essential for the Minister to grant a Notice of
Compliance (NOC) through the ANDS pathway for a generic drug. Health Canada’s
Guidance Document related to generic drug submissions were drawn up in
consultation with industry to establish a consistent and predictable interpretation
of the Regulations, and are being followed in this submission.
….
Based on the rationale I have provided in my
letter of October 27, 2015 and in this correspondence, I am prepared to
reconvene an external Reconsideration Panel to deliberate on the following
question:
Do the results from study OMEC03,
examined as part of the totality of evidence contained in this Abbreviated New
Drug Submission, provide reliable evidence of the bioavailability
characteristics of Apo-omeprazole delayed release tablets in order to assess
safety and effectiveness through bioequivalence with the Canadian Reference
Product as required in C.08.002.1 (2) of the Food and Drug Regulations?
Why or why not?
[75]
This last proposed question is also rejected by
Apotex.
B.
Issues and standard of review
[76]
The parties substantially agree on the issues
that need to be addressed:
(1)
The Minister suggests that the issue of
fettering her discretion is: Did the Minister fetter her discretion by
insisting that the question asked of the Reconsideration Panel address
bioequivalence? Apotex speaks in terms of fettering the discretion by
mechanically applying the bioequivalence criteria as an absolute requirement; and
(2)
The Minister puts forth that the legitimate
expectation issue is: Did Apotex have legitimate expectations to be allowed to
seek a reconsideration process? Apotex is slightly more precise by qualifying
the legitimate expectation as disallowing a reconsideration process which deals
with the issues put forward by Apotex.
[77]
There was no substantive discussion by the
parties of the standard of review applicable to the issues to be determined.
The Minister states that procedural fairness issues carry a standard of
correctness; that is not a novel proposition (Mission Institution v Khela,
2014 SCC 24, [2014] 1 S.C.R. 502, at para 79). She relies on the standard of
reasonableness with respect to issues of fact, discretion and policy. In fact,
the presumption goes further in that the Supreme Court has ruled regularly
since Alberta (Information and Privacy Commissioner) v Alberta Teachers’
Association, 2011 SCC 61, [2011] 3 S.C.R. 654 that “the
interpretation by the tribunal of “its own statute or statutes closely
connected to its function, with which it will have particular familiarity”
should be presumed to be a question of statutory interpretation subject to
deference on judicial review” (para 34).
[78]
If reasonableness is the appropriate standard of
review, the reviewing court will show deference and intervention will be
warranted only if the outcome does not fit within a range of acceptable,
possible outcomes, in recognition that these kinds of questions do not lend
themselves to one specific or particular result. The Court may disagree with
the decision, yet that disagreement does not lead to the decision being unreasonable.
The reviewing court will be concerned with justification, transparency and
intelligibility within the decision-making process in its search of
reasonableness (Dunsmuir v New Brunswick, 2008 SCC 9, [2008] 1 S.C.R. 190,
para 47).
[79]
That however does not answer what standard
applies in our case. As for the legitimate expectation doctrine, it seems to
proceed from the very notion of procedural fairness (Baker v Canada
(Minister of Citizenship and Immigration), [1999] 2 S.C.R. 817 [Baker]).
It is one of the participatory rights that are deserving of protection as a
matter of fairness. To the extent there is some legitimate expectation, the
standard of review will be correctness.
[80]
In the case of a tribunal or Minister that
fetters the discretion conferred by law, there is binding authority (Stemijon
Investments Ltd. v Canada (Attorney General), 2011 FCA 299) that “(a) decision that is the product of a fettered discretion
must per se be unreasonable” (para 24). That is because a
discretion of a certain scope cannot be abridged without, in effect, rewriting
the law.
[81]
Unfortunately for Apotex, it did not make a
convincing case that the Minister fettered her discretion or that there were
legitimate expectations which were not met. I begin with the latter.
(1)
Legitimate expectations
[82]
The doctrine of legitimate expectations is
procedural in nature. The following passage taken from Judicial Review of
Administrative Action in Canada, ((loose leaf), Thomson Reuters Canada, updated
August 2012) was cited with approval by the Supreme Court in Agraira v
Canada (Public Safety and Emergency Preparedness), 2013 SCC 36, [2013] 2
SCR 559 [Agraira] at para 95:
The distinguishing
characteristic of a legitimate expectation is that it arises from some conduct
of the decision-maker, or some other relevant actor. Thus, a legitimate
expectation may result from an official practice or assurance that certain
procedures will be followed as part of the decision-making process, or that a
positive decision can be anticipated. As well, the existence of administrative
rules of procedure, or a procedure on which the agency had voluntarily embarked
in a particular instance, may give rise to a legitimate expectation that such
procedures will be followed. Of course, the practice or conduct said to give
rise to the reasonable expectation must be clear, unambiguous and unqualified.
[83]
In Canada v Mavi, 2011 SCC 30, [2011] 2
SCR 504, the Supreme Court defined the doctrine as follows:
[68] Where a
government official makes representations within the scope of his or her
authority to an individual about an administrative process that the government
will follow, and the representations said to give rise to the legitimate
expectations are clear, unambiguous and unqualified, the government may be held
to its word, provided the representations are procedural in nature and do not
conflict with the decision maker’s statutory duty. Proof of reliance is not a
requisite. See Mount Sinai Hospital Center, at paras. 29-30; Moreau-Bérubé
v. New Brunswick (Judicial Council), 2002 SCC 11, [2002] 1 S.C.R. 249, at
para. 78; and C.U.P.E. v. Ontario (Minister of Labour), 2003 SCC 29,
[2003] 1 S.C.R. 539, at para. 131. It will be a breach of the duty of fairness
for the decision maker to fail in a substantial way to live up to its undertaking:
Brown and Evans, at pp. 7-25 and 7-26.
[84]
However, the doctrine of legitimate expectations
does not create substantive rights; the applicant cannot succeed on the merits,
except perhaps if the conduct of officials is such that there is a legitimate
expectation that the discretion will be exercised in favour of the applicant.
In Agraira, one reads at para 97:
[97] An
important limit on the doctrine of legitimate expectations is that it cannot
give rise to substantive rights (Baker, at para. 26; Reference re
Canada Assistance Plan (B.C.), [1991] 2 S.C.R. 525, at p. 557). In other
words, “[w]here the conditions for its application are satisfied, the Court may
[only] grant appropriate procedural remedies to respond to the
‘legitimate’ expectation” (C.U.P.E. v. Ontario (Minister of Labour),
2003 SCC 29, [2003] 1 S.C.R. 539, at para. 131 (emphasis added)).
[85]
I have looked long and hard to find evidence of
legitimate expectations being violated here. Apotex’s position is predicated on
its expected right to submit its issue, as it wants framed, as if this
reconsideration process was an appeal of some sort. It is not so much a process
that Apotex claims to be entitled to as the right to ask its question. At
paragraph 90 of its memorandum of fact and law, on reads that “(t)he Reconsideration Policy contemplates a process where
the External Panel opines on the issues raised by the manufacturer in
the request for reconsideration” [my emphasis]. The Reconsideration
Policy does no such thing.
[86]
In the case at hand, it is clear that the
fundamental difference between the parties is that Apotex did not want to be
confronted to a question the focus of which would be the bioequivalence of its
product compared to the Canadian reference product. It is noteworthy that the
only high fat meal study offered in 2013 was a study that was on the shelves
since 1998. It was not presented when the applicant made its ANDS resulting in
a decision in March 2003. Instead of submitting it once it was determined that
the submission cannot be successful in December 2008 without a fat fed study,
Apotex challenged the decision on the basis that it had vested rights to the
decision of 2003 when there was no such study. To no avail in this Court and
the Court of Appeal, where the Court commented that it would “be an absurd result to construe the Regulations in such a
way that the Minister could be compelled to issue a NOC even if she was not
satisfied that the drug in question is safe and effective” (Apotex,
para 30). Indeed, the reasons given for requiring a study with a high fat meal
are compelling.
[87]
After the unsuccessful trip to the federal
courts, Apotex still did not present its 1998 study; instead it submitted a
comparative bioavailability study that was conducted with a different test
product (Apo-Omeprazole tablets (omeprazole base)). That study did not provide
any useful information concerning the new drug (Apo-Omeprazole (omeprazole
magnesium)), according to the affidavit of Dr. Appleton. Apotex presented its
1998 study only when it refiled its ANDS in 2013 in order to satisfy the
requirement of bioequivalence where the new drug is consumed with a high fat
meal. As already indicated, the study failed, including because the study had
poor study design.
[88]
As a result, Apotex argues that it can get a
reconsideration panel, irrespective of the failure on bioequivalence, to opine
on the safety and effectiveness of the new drug by asking the Panel a question
whose focus is on the safety and effectiveness of its drug, thus avoiding
bioequivalence. There is nothing that I can find in the Reconsideration of
Final Decisions Issued for Human Drug Submissions that could lend itself to the
contention that it can support the legitimate expectation that Apotex can treat
the reconsideration process as its appeal on any issue, including the issue of
the safety and effectiveness of a new drug, using the short cut that is the
abbreviated new drug submission. The policy does not allow to circumvent the
requirement for bioequivalence found in the Regulations. The types of
issues that can be referred are rather interpretation of available data,
methodology and relative weight given to data. The list is most probably not
exhaustive, but it signals what can appropriately be brought before such a
panel. As I read the questions proposed by the respondent, they fall squarely
within those parameters dealing with bioequivalence. These questions were
categorically rejected by Apotex which decided early on that its best chance
was in bringing its case, as if it was an appeal, before the Reconsideration
Panel on the basis that its new drug satisfies the ultimate test that a drug
must be safe and effective. That cannot be a legitimate expectation about
procedure or practice that is clear, unambiguous and unqualified.
[89]
A fair reading of the Policy leads to the
conclusion that it applies to disputes stemming from a notice of non-compliance
withdrawal letter. That letter of July 28, 2014 is solely concerned with the
bioequivalence of Apotex’s product falling short on the basis of the submitted
study (OMEC03). As Apotex acknowledges at paragraph 26 of its memorandum of
fact and law, the reconsideration is geared towards the scientific disagreement
in the case of a rejected submission. Disputes on scientific issues may be
addressed by a panel having the appropriate expertise; the panel can provide a
useful opinion to the Director General who will decide in the end.
[90]
The legitimate expectation is concerned with
Apotex being given a fair opportunity to draft a question which would address
one issue eligible to be brought before a reconsideration panel: specific
outstanding issues are to be identified and the panel members will be selected
for their expertise relevant to the resolution of the matter. The
Reconsideration Panel is not the regulator. The Court finds that Apotex was
given a better than fair opportunity to draft, in consultation with the Office
of Science, a question that would be eligible.
[91]
The difference between the parties became
unshakeable when it became apparent that each party wished for the question to
deal with different issues. It is not that Apotex was not given the
opportunity. The opportunity was there, but the two ships were sailing in the
fog in different directions. The Director General eventually refused
reconsideration, as she is entitled to under the Policy (section 4). There was
a fair opportunity given. As I will try to show in the next section, if there
was any discretion, it was concerning how bioequivalence can be demonstrated,
not whether or not the new product is safe and effective; there cannot have
been a legitimate expectation about safety and effectiveness and have Apotex’s
question accepted for the referral to the Reconsideration Panel’s
consideration. Not only what is invoked by Apotex is not a practice that is
clear, unambiguous and unqualified, but it calls for a particular outcome on
the merits.
(2)
Fettering of discretion
[92]
There is fettering of discretion where the
decision-maker confines the exercise of discretion by refusing to consider
factors that are legally relevant. Guidelines are useful. I suspect
manufacturers would clamour for indications as to what the administration would
consider to be bioequivalent, given that “bioequivalence”
is not defined in the Regulations. As the Supreme Court put it in Kanthasamy
v Canada (Citizenship and Immigration), 2015 SCC 61, [2015] 3 S.C.R. 909,
following in the footsteps of Baker and Agraira:
[32] There is
no doubt, as this Court has recognized, that the Guidelines are useful in
indicating what constitutes a reasonable interpretation of a given provision of
the Immigration and Refugee Protection Act: Agraira, at para. 85.
But as the Guidelines themselves acknowledge, they are “not legally binding”
and are “not intended to be either exhaustive or restrictive”: Inland
Processing, s. 5. Officers can, in other words, consider the Guidelines in
the exercise of their s. 25(1) discretion, but should turn “[their] mind[s] to
the specific circumstances of the case”: Donald J. M. Brown and The Honourable
John M. Evans with the assistance of Christine E. Deacon, Judicial Review of
Administrative Action in Canada (loose-leaf), at p. 12-45. They should not
fetter their discretion by treating these informal Guidelines as if they were
mandatory requirements that limit the equitable humanitarian and compassionate
discretion granted by s. 25(1): see Maple Lodge Farms Ltd. v. Canada,
[1982] 2 S.C.R. 2, at p. 5; Ha v. Canada (Minister of Citizenship and
Immigration), [2004] 3 F.C.R. 195 (C.A.), at para. 71.
[93]
In the context of section 25 of the Immigration
and Refugee Protection Act (SC 2001, c 27), which allows the responsible
minister to grant an exemption from any applicable criteria or obligations of
the Act if justified by humanitarian and compassionate considerations, the Baker
Court found that “(t)he guidelines show what the
Minister considers a humanitarian and compassionate decision, and they are of
great assistance to the Court in determining whether the reasons of officer
Lorenz are supportable” (para 72). Guidelines are obviously not to be
discarded. Brown and Evans have written in their Judicial Review of
Administrative Action in Canada:
12:4421 Accordingly, a
decision-maker must be prepared to entertain and consider representations that
are designed to show not only that, properly interpreted, a rule or policy does
not cover the facts of a particular matter, but also that even if it does, an
exception should be made in light of the facts of the particular case. Thus, to
treat a policy as binding prior to its application may be seen as being premature.
…
Moreover, a policy that is so
detailed and definitive that it is replete with exceptions, is apt to be
regarded as an exercise of a legislative power that the agency does not
possess.
Nevertheless, valid guidelines and
policies can be considered in the exercise of discretion, provided that the
decision-maker puts his or her mind to the specific circumstances of the case.
Indeed, a court may refer to guidelines issued to those entrusted with the
exercise of discretion as an indication of the factors to be considered by the
decision-maker and, perhaps, their relative weight, when reviewing a
discretionary decision for unreasonableness.
[94]
It is not completely clear what discretion is
alleged to have been fettered by the respondent in the questions that were
proposed. According to its factum, the Minister would have fettered her
discretion by mechanically applying the bioequivalence criteria as an absolute
requirement. I must say that I have not found anything of the sort in any of
the questions offered by the Minister. It is not accurate to state that the
questions proposed by the respondent invited the Reconsideration Panel to treat
bioequivalence criteria as mandatory. There is simply no evidence to give an
air of reality to the contention that the Minister was bent on restricting the
Reconsideration Panel to strict adherence to the guidelines. With all due
respect, I have not found any persuasive evidence to that effect. Quite the
opposite. The only issue that is before this Court is the decision of the
Director General on November 16, 2015, to cancel the reconsideration sought by
Apotex. The reason for the cancellation is the disagreement expressed by Apotex
with all the proposed questions offered by the respondent including the last
one presented on November 6. I reproduce it again for ease of reference:
Do the results
from study OMEC03, examined as part of the totality of evidence contained in
this Abbreviated New Drug Submission, provide reliable evidence of the
bioavailability characteristics of Apo-omeprazole delayed release tablets in
order to assess safety and effectiveness through bioequivalence with the
Canadian reference product as required in C.08.002.1(2) of the Food and Drug
Regulations? Why or why not?
[95]
The reason for the need to discuss bioequivalence
is given in that same letter. It is because, “in order
to satisfy the regulatory requirement for this abbreviated new drug submission,
the question must lead the Panel to make a recommendation on whether Study
OMEC03 substantiates bioequivalence of your product with the Canadian Reference
Product.” Clearly, the Director General is referring to C.08.002.1 which
requires as part of the sufficient information and material evidence from
comparative studies about bioequivalence. In other words, it is not possible to
circumvent the Regulations; when the pathway is an ANDS, the generic
drug must establish bioequivalence with the Canadian reference product. The
scheme of the Regulations is such that “(i)t is
through establishing bioequivalence that a generic drug demonstrates safety and
effectiveness”, says the Director General. In my view, she is correct.
C.08.004(1) is unequivocal that “the Minister shall,
after completing an examination of … [an] abbreviated new drug submission … (a)
if that submission … complies with section … C.08.002.1 … issue a notice of
compliance”. The predicate to the issuance of a NOC is the compliance
with C.08.002.1 which itself calls for evidence of bioequivalence. That
question, and all other proposals before, never refers, directly or indirectly,
to the guidelines, let alone criteria. It merely posits that the question to
the Panel cannot avoid bioequivalence being at the heart of it, not that the
drug is safe and effective.
[96]
The Federal Court of Appeal is also of that
view. In Apotex Inc. v Canada (Health), 2011 FCA 86, 419 NR 300, the
Court found:
[7] We
agree with the Minister that all of the arguments of Apotex on this appeal are
based on the incorrect premise that it was open to the Minister to assess the
safety and efficacy of Apo-ASA without requiring proof of bioequivalence
between Apo-ASA and Bayer-ASA.
[8] Pursuant
to subparagraph C.08.002.1(2)(c)(ii) of the Food and Drug Regulations,
the Minister cannot issue a notice of compliance for Apo-ASA on the basis of
an abbreviated new drug submission naming Bayer-ASA as the Canadian
reference product unless bioequivalence is demonstrated between Apo-ASA and
Bayer-ASA. That is because a notice of compliance for a new product based
on an abbreviated new drug submission is intended to recognize that the new
product and the reference product are the same in certain material respects,
including bioequivalence. In other words, even if a proposed new product
is safe and effective, it cannot be approved through an abbreviated new drug
submission if it is not bioequivalent to the reference product.
[my emphasis]
In view of such binding authority, how can
it be validly argued that the Minister fetters her discretion when she does
precisely what the Regulations require of her and focuses the question
on bioequivalence instead of safety and effectiveness?
[97]
The purpose of the reconsideration in this case
is to ask a panel of experts to consider whether the only fat fed study offered
by the applicant, together with the totality of the evidence contained in the
AND submission, provides evidence of bioavailabity, as required by law. There
is no evidence that the Panel is to be confined to the guidelines. The
guidelines do not profess to have the force of law and the respondent has
acknowledged that they are not to be treated as law.
[98]
The applicant seems to be content to repeat that
there was insistence on strict compliance with the bioequivalence criteria.
There is no evidence that has been presented. Even an internal communication
raised by the applicant does not rise to the level. It is in fact innocuous.
But even if that were the case, that would not turn questions to be put to a
panel of independent scientific experts into instructions to follow strictly
guidelines which provide specifically that alternate approaches are acceptable
and that they are administrative in nature without force of law. This looks
very much like a straw man.
[99]
If the fettering is rather that the Minister had
to agree to a question, the focus of which is the demonstration of the safety
and effectiveness of the drug, that fettering can only be if the Minister had
that discretion. She does not. She could not agree with a question requiring
the Reconsideration Panel to opine on safety and effectiveness. That opinion
would have been of no use.
[100] The guideline documents feature prominently that they do not
constitute law. In fact, the exchange of proposed questions demonstrates that
although there was an absolute need to demonstrate bioequivalence because of
regulatory constraints, the requirements for how the bioequivalence was to be
demonstrated were not cast in stone. The last proposed question, on November 6,
2015, is an illuminating illustration that the Reconsideration Panel would be
asked to opine if the only study offered by Apotex, together with the totality
of the evidence, provides reliable evidence concerning bioequivalence. Apotex
repeated numerous times that it had the “perception”
that the guidelines were treated as law. It takes more than a “perception” to claim that discretion was fettered in
spite of the clear, unambiguous text of questions. The truth of the matter is
that the exchange of proposed questions showed that Apotex wished to avoid
bioequivalence altogether while the Minister felt constrained by the Regulations.
[101] The respondent is right to point to numerous statements found in the
Comparative Bioavailability Studies to illustrate the available flexibility:
1.2 The recommendations included in this
guidance respecting study design and conduct, validation of bioanalytical
methodology and statistical analysis of data should be followed in order to
ensure compliance with the regulations.
1.4 In the absence of an adequate methodology for bioavailability
testing, alternative approaches such as pharmacodynamics studies can be used.
In some instances, equivalence may have to be determined by clinical trials
with therapeutic end-points.
2.1 A rationale should be provided to justify which bioequivalence
standards will be applied. Scientific justification should be provided for any
deviation from the guidance set out in this document….Sponsors are encouraged
to consult with Health Canada, in advance of the study, if deviations are
substantial.
2.4.3.2 The meal used in a comparative bioavailability study conducted under
fed conditions should allow maximal perturbation of systemic bioavailability of
the drug from the drug product. This is generally a high-fat, high-calorie
meal. Thus, the default meal, for comparative bioavailability studies under fed
conditions, should be a high-fat, high-calorie meal…. Use of a meal other than
a high-fat, high-calorie meal should only occur under exceptional circumstances
and should be scientifically justified, a priori, by the submission sponsor.
Alternative approaches when scientifically justified
or deviations are expressly permitted. None of these have actually been
suggested in this case. That includes why it was appropriate to have high
fat/high calorie studies for this type of product. As was explained by Dr.
Appleton in his affidavit evidence, a low fat/low calorie meal does not
challenge the tablet’s enteric coat to the same extent as the high fat/high
calorie meal does. On the other hand, the high fat/high calorie meal provides
the best evidence concerning how that enteric coat behaves. For instance, this
kind of meal may coat the tablet in fat of fatty emulsion which can affect the
release of the drug. Hence, the fed study with high fat/high calorie meal at
one end, and the absorption of the new drug in fasting conditions, challenge the
enteric coating maximally.
[102] The Minister did not fetter her discretion in examining whether
there was bioequivalence between the new drug and the Canadian reference
product in her effort to articulate an appropriate question for the
Reconsideration Panel. Given that bioequivalence is required, the very wording
of the proposed questions, and especially the last question, was demonstrative
of the flexibility already noted in the guidelines documents.
[103] As indicated earlier, the ANDS pathway allows for compliance to be
found in spite of the fact that the assessment of safety and effectiveness
would otherwise require detailed reports of tests made to establish the safety
of the new drug and substantial evidence of the clinical effectiveness of the
new drug (C.08.002.1(2) and (a)(i) and C.08.002 (2)(a) and (h)). The proxy to
get to safety and effectiveness of a new drug through an ANDS is to “piggy-back” on the Canadian reference product which
has gone through the rigour of presenting “detailed
reports of tests” and “substantial evidence”.
But the Regulations require in those circumstances that there be
bioequivalence.
[104] Thus, the Minister cannot fetter a discretion she does not have. She
cannot abandon bioequivalence. A reconsideration exercise that would exclude bioequivalence
in favour of safety and effectiveness, as argued for by Apotex, would be
outside of the framework of the Regulations.
[105] At the hearing, Apotex seemed to adjust its position to now contend
that it knew it needed to show bioequivalence, but did not use that term in any
of its proposed questions because it feared Health Canada equated “bioequivalence” with the criteria set in the
bioequivalence guidelines and, therefore, the question’s outcome would be
pre-determined. One is hard pressed to find any support for that new
contention. There was never any attempt by Apotex to clarify. On the contrary,
from iteration to iteration, Apotex remained adamant that it wanted to show
that its drug was safe and effective because, in the words of Mr. Terrill, “(t)he issue raised is whether or not, despite our not having
provided such a study, the available information suffices to adequately
demonstrate safety and effectiveness, to at least the same extent as other
approved products.” If bioequivalence was part of the equation, Apotex
was hiding it very well.
[106] I was tempted to treat the explanation as inadmissible evidence, as
not being before the Director General when she took her decision on November
16, 2015. Instead, I have considered the “explanation”
and rejected it.
[107] I do not accept that the reference to safety and effectiveness was
used as a misnomer for bioequivalence by Apotex. As Apotex put it in its
factum, its questions have all along been variations on “Does the available information including the submitted bioequivalence
studies, reasonably suffice to conclude that Apo-Omeprazole tablets are safe
and effective?” It knows the difference between the two notions. The
evidence is rather that “safe and effective” was
used in contradistinction to “bioequivalent”. In
essence, the debate has been “safety and effectiveness”
versus “bioequivalence”. This was not only
during the debate on an appropriate question, but also throughout the official
documentation, including the notice of application before this Court, the
request for reconsideration itself and even the memorandum of fact and law.
[108] Given that the last question offered by the Minister focused on
bioequivalence, as it had to, contrary to what was argued by Apotex, there is
no basis to argue that the question is unreasonable. It was legitimate for the
Minister to require fat fed studies to establish bioequivalence and Apotex
chose to rely on its 15-years old study. The only such study is OMEC03 that
Apotex wished to exclude from questions. That question of November 6, 2015, is
eminently reasonable. The essential components of the question are
bioequivalence and the only fat fed study, to be examined with the totality of
the evidence in this ANDS, with a view to determining bioequivalence, not in
respect of the guidelines, but in respect of the Regulations. This
surely satisfies the requirements of reasonableness. Evidently, that does not
constitute the question the applicant wants answered, whatever its reasons. But
the applicant is not entitled to ask its question as its question would be
outside the scope of the Regulations. It would be absurd if the
applicant had to be allowed, as part of a reconsideration process, to raise
issues which cannot be considered, that is that its drug is safe and effective.
Only bioequivalence can do. To put it bluntly, the applicant did not have a
legitimate expectation that was defeated, the Minister did fetter her
discretion by insisting on the focus to be on bioequivalence and the question
is reasonable with its focus on bioequivalence including fat fed conditions. At
any rate, strictly speaking, the reasonableness of the question is not squarely
before the Court as the applicant framed its case in terms of legitimate
expectations and fettering of discretion in its notice of application.
[109] Apotex referred to other products which were approved without
strictly meeting the bioequivalence criteria of the guidelines. The Minister
argues that they met bioequivalence requirements. Even if they did not, it
seems to me that these examples would tend to show that the respondent does not
treat the guidelines with rigidity, thus fettering her discretion. They
obviously show deviations.
[110] Furthermore, both in his report of July 23, 2014, and in his
affidavit in this case, Dr. Appleton explained what actually took place in
these cases. There is no common measure between these cases and the
Apo-Omeprazole tablets.
[111] As for the Apo-Pantrozole, it was necessary to demonstrate
bioequivalence under fasting and fed conditions. The four bioavailability
studies covered fasting and low fat fed; however, Dr. Appleton reports a
pharmacodynamics study in high fat fed conditions comparing the new drug to a
Canadian reference product and included data from subjects who had taken the
drug following a high fat meal. It was approved.
[112] The Apo-Lanzoprazole is limited to administration of the drug before
a meal, in a fasted state. Nevertheless, a high fat fed study was asked for and
provided: it did not meet the bioequivalence acceptance criteria. However, the
high fat fed study confirmed that the new drug performed at least as well as
the Canadian reference product. Based on the totality of the data, the
reconsideration panel recommended that it was sufficient to consider the new
drug to be bioequivalent to the Canadian reference product. It is noteworthy
that this tends to show that reconsideration panels work in their examination
of what constitutes sufficient scientific evidence to demonstrate
bioequivalence.
[113] In the case of Apo-Omeprazole (omeprazole base) capsules, there was
a bioavailability study under fasting conditions and one under high fat fed
conditions. The high fat fed study did not meet the criteria. Apotex submitted
two more high fat fed bioavailability studies, but using as a comparator
reference products that are not Canadian; however, the Canadian reference
product, which was not marketed anymore, met the applicable standards for
bioequivalence with the non-Canadian reference product. The new drug was
approved. Dr. Appleton, in his report of July 23, 2014, wrote that “(t)he Cmax of 127% for the fed study with the CRP was just
outside the acceptance limit for Cmax (80-125%); this in combination with the
study with US Prilosec that passed acceptance criteria was judged to be
acceptable for granting a declaration of bioequivalence with the CRP.”
[114] For the sake of completeness, I reproduce the evidence of Dr.
Appleton concerning a fourth product, that of AstraZeneca’s omeprazole
magnesium enteric tablets. However, the pathway chosen was not the ANDS, but
rather the Supplemental New Drug Submissions [SNDS]:
41. Prior
to the approval of AstraZeneca Canada Inc.’s (“AstraZeneca”) Losec (omeprazole
magnesium) enteric tablets, AstraZeneca marketed an omeprazole capsule
formulation. In its submission for approval of Losec (omeprazole magnesium)
enteric-coated tablets, AstraZeneca submitted a study under high-fat fed
conditions. Other studies were provided to support Losec tablets. They were
approved in 1995 on the totality of the data submitted as SNDS. Since their
approval, more experience has been gained.
42. As
explained during a meeting between Health Canada officials and representatives
of Apotex on April 14, 2015, approval for a SNDS involves satisfying the
Minister of the safety and efficacy of the drug. A bioequivalence study between
Losec’s omeprazole capsules and omeprazole magnesium enteric-coated tablets was
not required under the FDR. Attached and marked as Exhibit “D” is
a copy of the Record of Decision Apo-Omeprazole Discussion Meeting on April 14,
2015. It is explicitly stated in the Product Monograph that Losec capsules are
not bioequivalent to the tablets. The approval of the tablets was based on a
number of studies and not the bioequivalence study alone.
[115] This evidence is of no assistance to Apotex if it seeks to show
fettering of discretion. It seems to show, on the contrary, that the Minister
shows flexibility in her application of the bioequivalence requirement in cases
of abbreviated new drug submissions. It also shows that bioequivalence is at
the center of an ANDS. It even indicates that the applicant has supplemented in
the past studies that were deficient on that front in order to obtain approval.
Nothing of the sort was done in this case. In fact, it would appear that the
applicant did not have much confidence in the one study that saw the light of
day fifteen years after its conclusion. Apotex chose to challenge in court the
need for high fat/high calorie evidence, by claiming vested rights in a
decision where there was no such evidence, and then offered a study which could
not be considered before putting forth OMEC03. Once offered as evidence, it
sought to circumvent the bioequivalence requirement by seeking to “appeal” to a Reconsideration Panel that its product
is safe and effective.
[116] I would therefore conclude that there is in this case no evidence of
fettering of discretion as to the application of the bioequivalence
requirement. The evidence is rather to the contrary as the other products reviewed
in Dr. Appleton’s evidence tend to prove. The Minister has to consider
bioequivalence, as per the Food and Drug Regulations, and she would be
acting outside the Regulations if she agreed to circumvent
bioequivalence in the reconsideration of the matter. As for her application of
bioequivalence, there is no evidence that the guidelines had taken the force of
law and were to be treated without the required flexibility. I have found no
evidence that other scientifically sound approaches or deviations were
forbidden or that Apotex wanted to rely on other scientifically sound
approaches to establish bioequivalence. That may very well be because, all
along, the applicant wanted an opinion on something other than the
bioequivalence of its drug: it wanted to establish before the Panel that its
drug is safe and effective. That was not possible because, as the Federal Court
of Appeal said in Apotex (2011 FCA 86), “even if
a proposed new product is safe and effective, it cannot be approved through an
abbreviated new drug submission if it is not bioequivalent to the reference
product” (para 8).
[117] Lastly, the applicant’s reliance on Apotex Inc. v Canada (Health),
2013 FC 1217, a decision rendered by my colleague, Justice Catherine Kane,
concerning a different new drug, Apo-Telmisartan, deserves some comments.
[118] This decision is in my view of no assistance to the applicant. The
issue on which the applicant was successful was the interpretation given by the
Minister to the term “identical medicinal ingredient”,
at the screening stage, a term found in the definition of “pharmaceutical equivalent” at C.08.001.1 of the Regulations.
The Court also found that the Minister’s position was inconsistent. This is of
no assistance to the applicant: this is not an interpretation of statute case
and the Minister has not been inconsistent. There is not in this case a
different interpretation given to the Regulations based on different
circumstances or chemical composition of the drug.
[119] Similarly, the issue that the Reconsideration Panel was cancelled
because the question must focus on bioequivalence with the Canadian reference product
and not on whether or not the new drug is safe and effective has no kinship
with the comments made in the Telmisartan case. Certainly, a question submitted
to a reconsideration panel that would avoid a key issue could prove to be
problematic. But that is not the case here. The proposed questions do not avert
the real or key issue. In the case at bar, it was not appropriate for the
Minister to consider any further a question to be put to the Reconsideration
Panel that is outside the scope of what can be put before a Panel, that is
whether or not a proposed new drug was safe and effective, instead of whether
bioequivalence is present.
[120] Counsel for the applicant, submitted, in extremis, that if
the Minister were willing to consider bioequivalence without fat fed studies,
the question would have been acceptable. Of course. That would take the matter
back to 2003 when the Minister was willing to accept bioequivalence without a
high fat study. That was then. This is not the case since the decision of
December 2008. I see no merit in that submission. Neither the NOC nor the
Notice of Non-Compliance Withdrawal Letter is challenged.
VII.
Conclusion
[121] Apotex’s case is predicated on its assertion, repeated numerous
times but never demonstrated, that the reconsideration would be limited to the
bioequivalence in the guidelines and/or bioequivalence criteria. Guidelines are
useful in helping make a determination that the interpretation of a term like “bioequivalence”, which is not defined in the Regulations,
is reasonable, but the guidelines cannot be given the force of law: they were
not. The issue put to the Reconsideration Panel had to turn on the notion of
bioequivalence. There is no evidence that the questions, as proposed, would
signal that the Reconsideration Panel would have to adhere to the strict
compliance to the guidelines. The only reference to bioequivalence is always in
relation to the Regulations, never the guidelines. As the last question
offered to Apotex continued to show, a panel of experts was to be asked to
opine if the study involving fat fed meals presented by Apotex to satisfy the
requirements of bioequivalence, together with the totality of the evidence, provides
reliable evidence of bioavailability characteristics in order to assess safety
and effectiveness through the bioequivalence with the Canadian reference product.
Apotex was not satisfied and chose to challenge before this Court. It failed.
[122] As permitted by the Reconsideration Policy, the Director General can
refuse reconsideration for decisions that are not eligible. It was clear in
this case that Apotex would not budge and that left little choice but to cancel
reconsideration.
[123] The applicant sought a number of remedies: quashing the November 16,
2015 decision to cancel the reconsideration, but directing the Minister to
continue the process without fettering her decision by insisting on strict
compliance with policies and guidelines. The question favoured by the applicant
ought to be put to the Panel, with its focus on the safety and effectiveness of
the new drug. Counsel for the applicant also suggested at the hearing that the
Court may be minded to simply return the matter to the Reconsideration Panel on
the basis of the last question offered by the Director General on November 6,
2015.
[124] It seems to me that that last-ditch effort on the part of the
applicant to salvage something should not succeed as it would require, as a
matter of law, that the Court quash the decision of November 16, 2015 which
very specifically concluded that “since we remain at an
impasse, and as I indicated in my letter of November 6, 2015, the
reconsideration of this submission, control number 162270 is cancelled, and the
Notice of Non-Compliance – Withdrawal issued on July 28, 2014 is now final”.
Without quashing the decision under review, there would be no way to send the
matter back on the basis of the very question rejected by Apotex. There is no
reason to quash that decision as there was no fettering of discretion and
legitimate expectations were met. As I have pointed out, the last question,
which was rejected by the applicant in spite of being warned that “(i)f your company does not agree or accept this approach, I
will consider your reconsideration request withdrawn and will declare the NON-W
final”, was rejected because it spoke in terms of bioequivalence and fat
fed studies. There was no fettering of discretion in a question that is
reasonable in the focus put on bioequivalence.
[125] The judicial review application is accordingly dismissed, with costs
in favour of the respondent. The parties were in agreement that the costs
should be assessed in accordance with Rule 407 of the Federal Courts Rules (SOR/98-106).
