Policy on 180-Day Marketing Exclusivity for Drugs Marketed Under
Abbreviated New Drug Applications; Clarification
AGENCY: Food and Drug Administration, HHS.
ACTION: Clarification.
-----------------------------------------------------------------------
SUMMARY: The Center for Drug Evaluation and Research (CDER) of the Food
and Drug Administration (FDA) is publishing this document to clarify
the status of its practices governing 180 days of marketing exclusivity
for generic drugs and the approval of abbreviated new drug applications
(ANDA's) subject to patent litigation. This document is being published
due to recent court decisions interpreting provisions of the Drug Price
Competition and Patent Term Restoration Act of 1984 (Pub. L. 98-417)
(the 1984 amendments).

SUPPLEMENTARY INFORMATION:
I. Background
The 1984 amendments included a provision, codified under section
505(j)(4)(B)(iv) of the Federal Food, Drug, and Cosmetic Act (the act)
(21 U.S.C. 355(j)(4)(B)(iv)), granting 180 days of marketing
exclusivity to the first applicant to submit an ANDA containing a
challenge to a listed patent. Regulations interpreting this provision
were proposed in 1989 (54 FR 28872, July 10, 1989), and made final in
1994 (59 FR 50338, October 3, 1994). These regulations are codified
under Sec. 314.107(c) (21 CFR 314.107(c)).
The regulations state that for a generic drug to qualify for 180
days of marketing exclusivity, the first ANDA applicant submitting a
certification under section 505(j)(2)(A)(vii)(IV) of the act (paragraph
IV certification) to the listed patent must, in addition to submitting
the certification, be sued for patent infringement and successfully
defend that suit (Sec. 314.107(c)). This interpretation has been the
subject of legal action in Inwood Laboratories, Inc. v. Young, 723 F.
Supp. 1523 (D.D.C. 1989), vacated as moot, 43 Fed.3d 712 (D.C.Cir.
1989); Mova Pharmaceutical Corp. v. Shalala, 955 F. Supp. 128 (D.D.C.
1997), and Granutec, Inc. et al. v. Shalala et al., No. 5:97-CV-485-
BO(1)(E.D.N.C. July 3, 1997). Both the Inwood and Mova courts held that
180 days of marketing exclusivity should be granted to the first ANDA
applicant who files a paragraph IV certification, regardless of whether
the applicant is subsequently sued for patent infringement. The Mova
decision has been appealed to the U.S. Court of Appeals for the
District of Columbia Circuit.
Following the Mova decision, in June 1997, the Office of Generic
Drugs notified applicants with ANDA's for ranitidine hydrochloride
(HCl) that the agency would acquiesce to the court's holding in Mova,
pending an appellate decision. The agency determined that temporarily
acquiescing to the court's holding in Mova would promote administrative
uniformity in the application of section 505(j)(4)(B)(iv) of the act
and would prevent forum shopping among disappointed ANDA applicants.
Subsequently, the U.S. District Court for the Eastern District of North
Carolina addressed the validity of Sec. 314.107(c) in Granutec v.
Shalala, and, in a holding contrary to the earlier Mova decision,
ordered FDA to follow its regulations in approving ANDA's for
ranitidine HCl. The Granutec decision was stayed and is on expedited
appeal to the U.S. Court of Appeals for the 4th Circuit.
Because the uncertain state of the law makes it difficult for the
industry to make business plans and other arrangements, CDER wishes to
clarify its policy with respect to these exclusivity issues, pending
their final resolution by the courts.
II. 180-Day Marketing Exclusivity
It is the agency's position that, given the uncertainty created by
the conflict among the courts, the most reasonable policy is to apply
the 180-day exclusivity provisions of the statute as set forth in
Sec. 314.107(c) to all ANDA's to which the regulation would, on its
face, apply, whether they were submitted before or after the Mova
decision. The only ANDA's to which the agency applied the Mova
analysis, other than those ANDA's directly involved in the Mova
litigation, were those for ranitidine HCl.
The regulations in Sec. 314.107(c) were issued through notice and
comment rulemaking with the active participation of the pharmaceutical
industry and consumer groups. They are the product of careful
consideration by the agency of the complex factors at issue in granting
a period of exclusivity to generic drug applicants and in ensuring that
the statute is implemented in a manner most consistent with its
original purpose. These regulations will be applied until such time as
the appellate courts complete their analyses of the agency's
interpretation.
III. Approval of ANDA's After Judgment in the District Courts
The agency does not intend to acquiesce to the court's decision in
Torpharm v. Shalala, Civil Action No. 97-1925 (JR) (D.D.C. Sept. 15,
1997), in which the court, finding that the term ``the court'' in
section 505(j)(4)(B)(iii) of the act means district court, ordered FDA
to approve an ANDA after the applicant had prevailed in patent
infringement litigation in the district court, but before either the
appeal was resolved or the 30-month stay had lapsed. The U.S. Court of
Appeals for the District of Columbia has granted the appeal of Torpharm
an expedited review. While Torpharm is pending on appeal, FDA will
continue to interpret the statute as described in Sec. 314.107(e),
which defines ``the court'' as ``the court that enters final judgment
from which no appeal can be or has been taken.''
