Determination of Regulatory Review Period for Purposes of Patent Extension; GALLIPRANT, 4214-4216 [2018-01640]

Download as PDF 4214 Federal Register / Vol. 83, No. 20 / Tuesday, January 30, 2018 / Notices daltland on DSKBBV9HB2PROD with NOTICES 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 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 ZEPATIER (grazoprevir; elbasvir). ZEPATIER is indicated with or without ribavirin for treatment of chronic hepatitis C virus genotypes 1 or 4 infection in adults. Subsequent to this approval, the USPTO received a patent term restoration application for ZEPATIER (U.S. Patent No. 7,973,040) from Merck Sharp & Dohme Corp. and MSD Italia s.r.l., and the USPTO requested FDA’s assistance in determining this patent’s eligibility for patent term restoration. In a letter dated November 10, 2016, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of ZEPATIER represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product’s regulatory review period. VerDate Sep<11>2014 18:18 Jan 29, 2018 Jkt 244001 II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for ZEPATIER is 1,865 days. Of this time, 1,619 days occurred during the testing phase of the regulatory review period, while 246 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: December 22, 2010. FDA has verified the applicant’s claim that the date the investigational new drug application became effective was on December 22, 2010. 2. The date the application was initially submitted with respect to the human drug product under section 505(b) of the FD&C Act: May 28, 2015. FDA has verified the applicant’s claim that the new drug application (NDA) for ZEPATIER (NDA 208–261) was initially submitted on May 28, 2015. 3. The date the application was approved: January 28, 2016. FDA has verified the applicant’s claim that NDA 208–261 was approved on January 28, 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 application for patent extension, this applicant seeks 188 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 petition FDA for a determination regarding whether the applicant for extension acted with due diligence during the regulatory review period. To meet its burden, the petition must comply with all the requirements of § 60.30, including but not limited to: Must be timely (see DATES), must be filed in accordance with § 10.20, must contain sufficient facts to merit an FDA investigation, and must certify that a true and complete copy of the petition has been served upon the patent applicant. (See H. Rept. 857, part 1, 98th Cong., 2d sess., pp. 41–42, 1984.) Petitions should be in the format specified in 21 CFR 10.30.

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 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 animal drug products, the 
testing phase begins on the earlier date when either a major 
environmental effects test was initiated for the drug or when an 
exemption under section 512(j) of the Federal Food, Drug, and Cosmetic 
Act (the FD&C Act) (21 U.S.C. 360b(j)) became effective and runs until 
the approval phase begins. The approval phase starts with the initial 
submission of an application to market the animal 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 an animal 
drug product will include all of the testing phase and approval phase 
as specified in 35 U.S.C. 156(g)(4)(B).
    FDA has approved for marketing the animal drug product GALLIPRANT 
(grapiprant). GALLIPRANT is indicated for the control of pain and 
inflammation associated with osteoarthritis in dogs. Subsequent to this 
approval, the USPTO received a patent term restoration application for 
GALLIPRANT (U.S. Patent No. 7,960,407) from AskAt Inc., and the USPTO 
requested FDA's assistance in determining this patent's eligibility for 
patent term restoration. In a letter dated September 26, 2016, FDA 
advised the USPTO that this animal drug product had undergone a 
regulatory review period and that the approval of GALLIPRANT 
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 
GALLIPRANT is 1,688 days. Of this time, 1,636 days occurred during the 
testing phase of the regulatory review period, while 52 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 (the FD&C Act) (21 U.S.C. 355(i)) became 
effective: August 8, 2011. The applicant claims July 7, 2009, as the 
date the investigational new animal drug application (INAD) became 
effective. However, FDA records indicate that the INAD effective date

[[Page 4216]]

was August 8, 2011, which was the date a major health or environmental 
effects test was begun.
    2. The date the application was initially submitted with respect to 
the animal drug product under section 512 of the FD&C Act (21 U.S.C. 
360b): January 29, 2016. The applicant claims January 25, 2016, as the 
date the new animal drug application (NADA) for GALLIPRANT (NADA 141-
455) was initially submitted. However, FDA records indicate that NADA 
141-455 was submitted on January 29, 2016.
    3. The date the application was approved: March 20, 2016. The 
applicant claims that NADA 141-455 was approved on March 21, 2016, 
however, FDA records indicate that NADA 141-455 was approved on Sunday, 
March 20, 2016.
    This determination of the regulatory review period establishes the
