Commerce, for the extension of patents which claims that human 
biological product.

DATES: Anyone with knowledge that any of the dates as published (see 
SUPPLEMENTARY INFORMATION) are incorrect may submit either electronic 
or written comments and ask for a redetermination by August 30, 2021. 
Furthermore, any interested person may petition FDA for a determination 
regarding whether the applicant for extension acted with due diligence 
during the regulatory review period by

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 human biological products, the 
testing phase begins when the exemption to permit the clinical 
investigations of the biological product becomes effective and runs 
until the approval phase begins. The approval phase starts with the 
initial submission of an application to market the human biological 
product and continues until FDA grants permission to market the 
biological 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 biological 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 biologic product POLIVY 
(polatuzumab vedotin-piiq). POLIVY is indicated in combination with 
bendamustine and a rituximab product for the treatment of adult 
patients with relapsed or refractory diffuse large B-cell lymphoma, not 
otherwise specified, after at least two prior therapies. Subsequent to 
this approval, the USPTO received patent term restoration applications 
for POLIVY (U.S. Patent Nos. 8,088,378; 8,545,850; and 8,691,531) from 
Genentech, Inc., and the USPTO requested FDA's assistance in 
determining this patents' eligibility for patent term restoration. In a 
letter dated May 8, 2020, FDA advised the USPTO that this human 
biological product had undergone a regulatory review period and that 
the approval of POLIVY represented the first permitted commercial 
marketing or use of the product. Thereafter, the USPTO

[[Page 34770]]

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 
POLIVY is 3,050 days. Of this time, 2,876 days occurred during the 
testing phase of the regulatory review period, while 174 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 (21 U.S.C. 355(i)) became effective: February 4, 
2011. FDA has verified the applicant's claims that the date the 
investigational new drug application became effective was on February 
4, 2011.
    2. The date the application was initially submitted with respect to 
the human biological product under section 351 of the Public Health 
Service Act (42 U.S.C. 262): December 19, 2018. FDA has verified the 
applicant's claim that the biologics license application (BLA) for 
POLIVY (BLA 761121) was initially submitted on December 19, 2018.
    3. The date the application was approved: June 10, 2019. FDA has 
verified the applicant's claim that BLA 761121 was approved on June 10, 
2019.
    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 1,032 days, 1,127 days, or 1,445 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 Sec.  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 Sec.  60.30, including but not limited to: Must be timely (see 
DATES), must be filed in accordance with Sec.  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.
    Submit petitions electronically to https://www.regulations.gov at 
Docket No. FDA-2013-S-0610. Submit written petitions (two copies are 
required) to the Dockets Management Staff (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
