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 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 BREYANZI
(lisocabtagene maraleucel). BREYANZI
[[Page 26322]]
is indicated for treatment of adult patients with large B-cell lymphoma
(LBCL), including diffuse large B-cell lymphoma (DLBCL) not otherwise
specified (including DLBCL arising from indolent lymphoma), high-grade
B-cell lymphoma, primary mediastinal large B-cell lymphoma, and
follicular lymphoma grade 3B, who have:
[cir] Refractory disease to first-line chemoimmunotherapy or
relapse within 12 months of first-line chemoimmunotherapy; or
[cir] Refractory disease to first-line chemoimmunotherapy or
relapse after first-line chemoimmunotherapy and are not eligible for
hematopoietic stem cell transplantation (HSCT) due to comorbidities or
age; or
[cir] Relapsed or refractory disease after two or more lines of
systemic therapy.
Subsequent to this approval, the USPTO received a patent term
restoration application for BREYANZI (U.S. Patent No. 10,736,918 and
10,780,118 and 10,780,118) from Juno Therapeutics, Inc. (agent for Fred
Hutchinson Cancer Research Center and Seattle Children's Hospital), and
the USPTO requested FDA's assistance in determining the patents'
eligibility for patent term restoration. In a letter dated April 3,
2024, FDA advised the USPTO that this human biological product had
undergone a regulatory review period and that the approval of BREYANZI
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
BREYANZI is 2,607 days. Of this time, 2,191 days occurred during the
testing phase of the regulatory review period, while 416 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: December
19, 2013. FDA has verified the applicant's claim that the date the
investigational new drug application became effective was on December
19, 2013.
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 18, 2019. FDA has verified the
applicant's claim that the biologics license application (BLA) for
BREYANZI (BLA 125714) was initially submitted on December 18, 2019.
3. The date the application was approved: February 5, 2021. FDA has
verified the applicant's claim that BLA 125714 was approved on February
5, 2021.
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 137 days or 179 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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> 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.
