Determination of Regulatory Review Period for Purposes of Patent Extension; XIIDRA, 7733-7735 [2023-02452]

Download as PDF Federal Register / Vol. 88, No. 24 / Monday, February 6, 2023 / Notices moderately to severely active rheumatoid arthritis who have had an inadequate response to one or more tumor necrosis factor antagonist therapies. Subsequent to this approval, the USPTO received a patent term restoration application for OLUMIANT (U.S. Patent No. 8,158,616) from Eli Lilly and Co., and the USPTO requested FDA’s assistance in determining the patent’s eligibility for patent term restoration. In a letter dated June 21, 2019, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of OLUMIANT represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product’s regulatory review period. DDrumheller on DSK120RN23PROD with NOTICES II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for OLUMIANT is 3,649 days. Of this time, 2,781 days occurred during the testing phase of the regulatory review period, while 868 days occurred during the approval phase. These periods of time were derived from the following dates: 1. The date an exemption under section 505(i) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 355(i)) became effective: June 5, 2008. FDA has verified the applicant’s claim that the date the investigational new drug application became effective was on June 5, 2008. 2. The date the application was initially submitted with respect to the human drug product under section 505 of the FD&C Act: January 15, 2016. FDA has verified the applicant’s claim that the new drug application (NDA) for OLUMIANT (NDA 207924) was initially submitted on January 15, 2016. 3. The date the application was approved: May 31, 2018. FDA has verified the applicant’s claim that NDA 207924 was approved on May 31, 2018. This determination of the regulatory review period establishes the maximum potential length of a patent extension. However, the USPTO applies several statutory limitations in its calculations of the actual period for patent extension. In its application for patent extension, this applicant seeks 723 days of patent term extension. III. Petitions Anyone with knowledge that any of the dates as published are incorrect may submit either electronic or written comments and, under 21 CFR 60.24, ask for a redetermination (see DATES). Furthermore, as specified in § 60.30 (21 CFR 60.30), any interested person may VerDate Sep<11>2014 18:51 Feb 03, 2023 Jkt 259001 petition FDA for a determination regarding whether the applicant for extension acted with due diligence during the regulatory review period.

SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 18:51 Feb 03, 2023 Jkt 259001 I. Background The Drug Price Competition and Patent Term Restoration Act of 1984 (Pub. L. 98–417) and the Generic Animal Drug and Patent Term Restoration Act (Pub. L. 100–670) generally provide that a patent may be extended for a period of up to 5 years so long as the patented item (human drug or biologic product, animal drug product, medical device, food additive, or color additive) was subject to regulatory review by FDA before the item was marketed. Under these acts, a product’s regulatory review period forms the basis for determining the amount of extension an applicant may receive. A regulatory review period consists of two periods of time: a testing phase and an approval phase. For human drug products, the testing phase begins when the exemption to permit the clinical investigations of the drug becomes effective and runs until the approval phase begins. The approval phase starts with the initial submission of an application to market the human drug product and continues until FDA grants permission to market the drug product. Although only a portion of a regulatory review period may count toward the actual amount of extension that the Director of USPTO may award (for example, half the testing phase must be subtracted as well as any time that may have occurred before the patent was issued), FDA’s determination of the length of a regulatory review period for a human drug product will include all of the testing phase and approval phase as specified in 35 U.S.C. 156(g)(1)(B). FDA has approved for marketing the human drug product, XIIDRA (lifitegrast) indicated for treatment of the signs and symptoms of dry eye disease. Subsequent to this approval, the USPTO received patent term restoration applications for XIIDRA (U.S. Patent Nos.: 7,314,938; 7,790,743; 8,084,047; 8,168,655; 8,592,450) from SARcode Bioscience Inc. and the USPTO requested FDA’s assistance in determining the patents’ eligibility for patent term restoration. In a letter dated May 13, 2019, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of XIIDRA represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product’s regulatory review period. PO 00000 Frm 00061 Fmt 4703 Sfmt 4703 II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for XIIDRA is 2,883 days. Of this time, 2,380 days occurred during the testing phase of the regulatory review period, while 503 days occurred during the approval phase. These periods of time were derived from the following dates: 1. The date an exemption under section 505(i) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 355(i)) became effective: August 21, 2008.

FDA has verified the applicant’s claim that the new drug application (NDA) for XIIDRA (NDA 208073) was initially submitted on February 25, 2015. 3. The date the application was approved: July 11, 2016. FDA has verified the applicant’s claim that NDA 208073 was approved on July 11, 2016. This determination of the regulatory review period establishes the maximum potential length of a patent extension. However, the USPTO applies several statutory limitations in its calculations of the actual period for patent extension. In its applications for patent extension, this applicant seeks 1,693 days, 1,319 days, 1,081 days, 1,018 days or 731 days of patent term extension. III.

SUPPLEMENTARY INFORMATION:

I. Background

The Drug Price Competition and Patent Term Restoration Act of 1984
(Pub. L. 98-417) and the Generic Animal Drug and Patent Term
Restoration Act (Pub. L. 100-670) generally provide that a patent may
be extended for a period of up to 5 years so long as the patented item
(human drug or biologic product, animal drug product, medical device,
food additive, or color additive) was subject to regulatory review by
FDA before the item was marketed. Under these acts, a product's
regulatory review period forms the basis for determining the amount of
extension an applicant may receive.
A regulatory review period consists of two periods of time: a
testing phase and an approval phase. For human drug products, the
testing phase begins when the exemption to permit the clinical
investigations of the drug becomes effective and runs until the
approval phase begins. The approval phase starts with the initial
submission of an application to market the human drug product and
continues until FDA grants permission to market the drug product.
Although only a portion of a regulatory review period may count toward
the actual amount of extension that the Director of USPTO may award
(for example, half the testing phase must be subtracted as well as any
time that may have occurred before the patent was issued), FDA's
determination of the length of a regulatory review period for a human
drug product will include all of the testing phase and approval phase
as specified in 35 U.S.C. 156(g)(1)(B).
FDA has approved for marketing the human drug product, XIIDRA
(lifitegrast) indicated for treatment of the signs and symptoms of dry
eye disease. Subsequent to this approval, the USPTO received patent
term restoration applications for XIIDRA (U.S. Patent Nos.: 7,314,938;
7,790,743; 8,084,047; 8,168,655; 8,592,450) from SARcode Bioscience
Inc. and the USPTO requested FDA's assistance in determining the
patents' eligibility for patent term restoration. In a letter dated May
13, 2019, FDA advised the USPTO that this human drug product had
undergone a regulatory review period and that the approval of XIIDRA
represented the first permitted commercial marketing or use of the
product. Thereafter, the USPTO requested that FDA determine the
product's regulatory review period.

II. Determination of Regulatory Review Period

FDA has determined that the applicable regulatory review period for
XIIDRA is 2,883 days. Of this time, 2,380 days occurred during the
testing phase of the regulatory review period, while 503 days occurred
during the approval phase. These periods of time were derived from the
following dates:
1. The date an exemption under section 505(i) of the Federal Food,
Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 355(i)) became effective:
August 21, 2008. FDA has verified the applicant's claim that the date
the investigational new drug application became effective was on August
21, 2008.
2. The date the application was initially submitted with respect to
the human drug product under section 505 of the FD&C Act: February 25,
2015. FDA has verified the applicant's claim that the new drug

731 days of patent term extension.
