Determination of Regulatory Review Period for Purposes of Patent Extension; INREBIC, 59397-59399 [2021-23388]

Download as PDF Federal Register / Vol. 86, No. 205 / Wednesday, October 27, 2021 / Notices Generally, registered blood establishments are inspected on a biennial basis by the Agency. There are approximately 1,900 registered blood establishments that manufacture blood and blood components for transfusion, all located in the United States, except a small number of United States military blood establishments that are located internationally in order to provide blood and blood components to United States military personnel onsite when needed. The supply chains for blood and blood components for transfusion are wellestablished and well-understood based on the nature of the products; namely, blood is collected from human donors via venipuncture, separated into components (if applicable), and stored at specified temperatures and under the complete control of each blood establishment. Additionally, supply chains for blood and blood components for transfusion are controlled and secure from initial donation to final product delivery to the transfusion site and, generally, do not involve wholesale distributors, brokers, or other intermediaries. Further, many registered blood establishments voluntarily submit the amount of blood and blood components for transfusion manufactured as part of the Health and Human Services National Blood Collection and Utilization Survey (NBCUS), which, historically, has a high response rate.1 lotter on DSK11XQN23PROD with NOTICES1 2. Cell and Gene Therapy Products, Where One Lot Treats a Single Patient In accordance with section 510(j)(3)(B) of the FD&C Act, FDA is proposing to exempt cell and gene therapy products, where one lot treats a single patient, from the reporting requirements under section 510(j)(3)(A) of the FD&C Act. In light of FDA’s existing visibility into the supply chain for this category of products, requiring registrants to report annually under section 510(j)(3)(A) of the FD&C Act on the amount of such products manufactured, prepared, propagated, compounded, or processed for commercial distribution, is not needed to enhance the Agency’s ability to identify, prevent, and mitigate possible shortages. As such, FDA has determined that applying the reporting requirements under section 510(j)(3)(A) of the FD&C Act to this category of biological products is not necessary to protect the public health. 1 See https://doi.org/10.1111/trf.16449. The response rate for the 2019 NBCUS was 94 percent for community-based blood collection facilities and 84 percent for hospital-based blood collection facilities. VerDate Sep<11>2014 16:47 Oct 26, 2021 Jkt 256001 Manufacturers of cell and gene therapy products, where one lot treats a single patient, maintain a highly controlled and secure supply chain from initial request for treatment of a patient to final product delivery to the site where the treatment occurs. This is because, due to the nature of these products, manufacturers implement strict chain of identity procedures to track products through the manufacturing process, to make sure the correct product gets to the correct patient. Additionally, the supply chains for these products are well-established and well-understood from information described in the biologics license application (BLA), and generally do not involve wholesale distributors, brokers, or other intermediaries. Additionally, pursuant to § 600.81 (21 CFR 600.81), the Agency generally receives lot distribution reports every 6 months from BLA holders. Specifically, reports submitted to the Agency under § 600.81 include, among other information, the fill lot numbers for the total number of dosage units of each strength or potency distributed, the label lot number (if different from fill lot number), the number of doses in fill lot/ label lot, and the date of release of fill lot/label lot for distribution. For this category of biological products, since one lot treats a single patient, the lot distribution reports submitted to the Agency under § 600.81 represent the amount of product manufactured for commercial distribution, and additional reporting of such information under section 510(j)(3)(A) of the FD&C Act would be redundant. III. Paperwork Reduction Act of 1995 This proposed order contains information collection provisions that are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501–3521). Information collection associated with section 510(j)(3) of the FD&C Act, requiring each person who registers with FDA with regard to a drug to report annually to FDA on the amount of each listed drug that was manufactured, prepared, propagated, compounded, or processed by such person for commercial distribution, is approved under OMB control number 0910–0045. If finalized, we believe the order will reduce burden associated with the approved information collection by exempting these biological product categories from such reporting requirements. We invite comment on our assumptions. PO 00000 Frm 00038 Fmt 4703 Sfmt 4703 59397 IV. Proposed Effective Date FDA proposes that any final order based on this proposed order become effective 30 days after its date of publication in the Federal Register. Dated: October 21, 2021.

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 PO 00000 Frm 00039 Fmt 4703 Sfmt 4703 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, INREBIC (fedratinib), indicated for the treatment of adult patients with intermediate-2 or high-risk primary or secondary (postpolycythemia vera or post-essential thrombocythemia) myelofibrosis. Subsequent to this approval, the USPTO received patent term restoration applications for INREBIC (U.S. Patent Nos. 7,528,143; 7,825,246; and 8,138,199) from Impact Biomedicines, Inc., and the USPTO requested FDA’s assistance in determining the patents’ eligibility for patent term restoration. In a letter dated January 4, 2021, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of INREBIC 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 INREBIC is 4,285 days. Of this time, 4,059 days occurred during the testing phase of the regulatory review period, while 226 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: November 24, 2007. FDA has verified the applicant’s claims that the date the investigational new drug application became effective was on November 24, 2007. E:\FR\FM\27OCN1.SGM 27OCN1 Federal Register / Vol. 86, No. 205 / Wednesday, October 27, 2021 / Notices 2. The date the application was initially submitted with respect to the human drug product under section 505 of the FD&C Act: January 3, 2019. FDA has verified the applicant’s claims that the new drug application (NDA) for INREBIC (NDA 212327) was initially submitted on January 3, 2019. 3. The date the application was approved: August 16, 2019. FDA has verified the applicant’s claims that NDA 212327 was approved on August 16, 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 1,271 days, 1,523 days or 1,796 days of patent term extension. III. Petitions lotter on DSK11XQN23PROD with NOTICES1 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.

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, INREBIC 
(fedratinib), indicated for the treatment of adult patients with 
intermediate-2 or high-risk primary or secondary (post-polycythemia 
vera or post-essential thrombocythemia) myelofibrosis. Subsequent to 
this approval, the USPTO received patent term restoration applications 
for INREBIC (U.S. Patent Nos. 7,528,143; 7,825,246; and 8,138,199) from 
Impact Biomedicines, Inc., and the USPTO requested FDA's assistance in 
determining the patents' eligibility for patent term restoration. In a 
letter dated January 4, 2021, FDA advised the USPTO that this human 
drug product had undergone a regulatory review period and that the 
approval of INREBIC 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 
INREBIC is 4,285 days. Of this time, 4,059 days occurred during the 
testing phase of the regulatory review period, while 226 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: 
November 24, 2007. FDA has verified the applicant's claims that the 
date the investigational new drug application became effective was on 
November 24, 2007.

[[Page 59399]]

    2. The date the application was initially submitted with respect to 
the human drug product under section 505 of the FD&C Act: January 3, 
2019. FDA has verified the applicant's claims that the new drug 
application (NDA) for INREBIC (NDA 212327) was initially submitted on 
January 3, 2019.
    3. The date the application was approved: August 16, 2019. FDA has 
verified the applicant's claims that NDA 212327 was approved on August 
16, 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 1,271 days, 1,523 days or 1,796 days of patent 
term extension.

III. Petitions
