SUPPLEMENTARY INFORMATION: khammond on DSKJM1Z7X2PROD 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 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 VerDate Sep<11>2014 16:50 Dec 07, 2023 Jkt 262001 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 Nuzyra Tablets (NDA 209816) (omadacycline). Nuzyra Tablets (NDA 209816) is indicated for the treatment of adult patients with the following infections caused by susceptible microorganisms: • Community-acquired bacterial pneumonia, and • Acute bacterial skin and skin structure infections. Subsequent to this approval, the USPTO received a patent term restoration application for Nuzyra Tablets (NDA 209816) (U.S. Patent No. 9,265,740) from Paratek Pharmaceuticals, Inc., and the USPTO requested FDA’s assistance in determining the patent’s eligibility for patent term restoration. In a letter dated December 23, 2019, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of Nuzyra Tablets (NDA 209816) and Nuzyra Injection (NDA 209817) represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the products’ regulatory review period. II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for Nuzyra Tablets (NDA 209816) is 4,361 days. Of this time, 4,118 days occurred during the testing phase of the regulatory review period, while 243 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: October 26, 2006. The applicant claims September 26, 2006, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was PO 00000 Frm 00067 Fmt 4703 Sfmt 4703 October 26, 2006, which was 30 days after FDA receipt of the IND. 2. The date the application was initially submitted with respect to the human drug product under section 505 of the FD&C Act: February 2, 2018. FDA has verified the applicant’s claim that the NDA for Nuzyra Tablets (NDA 209816) was initially submitted on February 2, 2018. 3. The date the application was approved: October 2, 2018. FDA has verified the applicant’s claim that NDA 209816 was approved on October 2, 2018. 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 597 days of patent term extension. Note: We have determined that the regulatory review period for the human drug product, Nuzyra, approved under NDA 209816 is the same as the regulatory review period determined for the human drug product, Nuzyra, approved under NDA 209817. 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 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 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 Nuzyra 
Tablets (NDA 209816) (omadacycline). Nuzyra Tablets (NDA 209816) is 
indicated for the treatment of adult patients with the following 
infections caused by susceptible microorganisms:
     Community-acquired bacterial pneumonia, and
     Acute bacterial skin and skin structure infections.
    Subsequent to this approval, the USPTO received a patent term 
restoration application for Nuzyra Tablets (NDA 209816) (U.S. Patent 
No. 9,265,740) from Paratek Pharmaceuticals, Inc., and the USPTO 
requested FDA's assistance in determining the patent's eligibility for 
patent term restoration. In a letter dated December 23, 2019, FDA 
advised the USPTO that this human drug product had undergone a 
regulatory review period and that the approval of Nuzyra Tablets (NDA 
209816) and Nuzyra Injection (NDA 209817) represented the first 
permitted commercial marketing or use of the product. Thereafter, the 
USPTO requested that FDA determine the products' regulatory review 
period.

II. Determination of Regulatory Review Period

    FDA has determined that the applicable regulatory review period for 
Nuzyra Tablets (NDA 209816) is 4,361 days. Of this time, 4,118 days 
occurred during the testing phase of the regulatory review period, 
while 243 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: 
October 26, 2006. The applicant claims September 26, 2006, as the date 
the investigational new drug application (IND) became effective. 
However, FDA records indicate that the IND effective date was October 
26, 2006, which was 30 days after FDA receipt of the IND.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505 of the FD&C Act: February 2, 
2018. FDA has verified the applicant's claim that the NDA for Nuzyra 
Tablets (NDA 209816) was initially submitted on February 2, 2018.
    3. The date the application was approved: October 2, 2018. FDA has 
verified the applicant's claim that NDA 209816 was approved on October 
2, 2018.
    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 597 days of patent term extension.

    Note:  We have determined that the regulatory review period for 
the human drug product, Nuzyra, approved under NDA 209816 is the 
same as the regulatory review period determined for the human drug 
product, Nuzyra, approved under NDA 209817.

III. Petitions

    Anyone with knowledge that any of the dates as published are
