Determination of Regulatory Review Period for Purposes of Patent Extension; XERMELO, 67296-67298 [2018-28218]

Download as PDF amozie on DSK3GDR082PROD with NOTICES1 67296 Federal Register / Vol. 83, No. 248 / Friday, December 28, 2018 / Notices 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 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, RYDAPT (midostaurin). RYDAPT is indicated for treatment of adult patients with: • Newly diagnosed acute myeloid leukemia (AML) that is FLT3 mutationpositive as detected by an FDAapproved test, in combination with standard cytarabine and daunorubicin induction and cytarabine consolidation. (Limitations of Use: RYDAPT is not indicated as a single-agent induction therapy for the treatment of patients with AML.) • Aggressive systemic mastocytosis, systemic mastocytosis with associated hematological neoplasm, or mast cell leukemia. Subsequent to this approval, the USPTO received patent term restoration applications for RYDAPT (U.S. Patent Nos. 7,973,031; 8,222,244; and 8,575,146) from Novartis AG and DanaFarber Cancer Institute Inc., and the USPTO requested FDA’s assistance in determining the patent’s eligibility for patent term restoration. In a letter dated January 9, 2018, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of RYDAPT represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product’s regulatory review period. VerDate Sep<11>2014 18:13 Dec 27, 2018 Jkt 247001 II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for RYDAPT is 6,737 days. Of this time, 6,494 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: November 19, 1998. The applicants claim October 19, 1988, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was on November 19, 1998, 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(b) of the FD&C Act: August 29, 2016. FDA has verified the applicants’ claims that the new drug application (NDA) for RYDAPT (NDA 207997) was initially submitted on August 29, 2016. 3. The date the application was approved: April 28, 2017. FDA has verified the applicants’ claims that NDA 207997 was approved on April 28, 2017. 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, these applicants seek 147 days, 994 days, and 1,183 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.

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 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, XERMELO 
(telotristat ethyl hippurate). XERMELO is indicated for treatment of 
carcinoid syndrome diarrhea in combination with somatostatin analog 
(SSA) therapy in adults inadequately controlled by SSA therapy. 
Subsequent to this approval, the USPTO received a patent term 
restoration application for XERMELO (U.S. Patent No. 7,709,493) from 
Lexicon Pharmaceuticals, Inc., and the USPTO requested FDA's assistance 
in determining the patent's eligibility for patent term restoration. In 
a letter dated January 9, 2018, FDA advised the USPTO that this human 
drug product had undergone a regulatory review period and that the 
approval of XERMELO 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 
XERMELO is 3,329 days. Of this time, 2,993 days occurred during the 
testing phase of the regulatory review period, while 336 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 20, 2008. FDA has verified the applicant's claim that the date 
the investigational new drug application became effective was on 
January 20, 2008.

[[Page 67298]]

    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the FD&C Act: March 30, 
2016. FDA has verified the applicant's claim that the new drug 
application (NDA) for XERMELO (NDA 208794) was initially submitted on 
March 30, 2016.
    3. The date the application was approved: February 28, 2017. FDA 
has verified the applicant's claim that NDA 208794 was approved on 
February 28, 2017.
    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 1,175 days of patent term extension.

III. Petitions
