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 biological 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 VerDate Sep<11>2014 20:05 Jun 18, 2025 Jkt 265001 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, ZILBRYSQ (zilucoplan) indicated for the treatment of generalized myasthenia gravis in adult patients who are antiacetylcholine receptor antibody positive. Subsequent to this approval, the USPTO received a patent term restoration application for ZILBRYSQ (U.S. Patent No./Nos. 10,106,579; 10,208,089; 10,562,934; 10,835,574) from UCB Inc. on behalf of Ra Pharmaceuticals, Inc. and the USPTO requested FDA’s assistance in determining the patent’s eligibility for patent term restoration. In a letter dated April 17, 2024, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of ZILBRYSQ 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 ZILBRYSQ is 2,477 days. Of this time, 2,064 days occurred during the testing phase of the regulatory review period, while 413 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: January 6, 2017. The applicant claims September 29, 2017, as the date the investigational new drug application (IND) became effective. However, FDA’s records indicate that the effective date was January 6, 2017, which was the first date after receipt of an earlier IND that the investigational studies could proceed. 2. The date the application was initially submitted with respect to the human drug product under section 505 of the FD&C Act: August 31, 2022. FDA has verified the applicant’s claim that the new drug application (NDA) for ZILBRYSQ (NDA 216834) was initially submitted on August 31, 2022. 3. The date the application was approved: October 17, 2023. FDA has PO 00000 Frm 00055 Fmt 4703 Sfmt 4703 verified the applicant’s claim that NDA 216834 was approved on October 17, 2023. 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 739 days or 858 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 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:

    This determination of the regulatory review period establishes the 
maximum potential length of a patent extension. However, the USPTO

this applicant seeks 137 days or 179 days of patent term extension.
