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
[[Page 17584]]
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, TEGSEDI
(inotersen sodium) indicated for treatment of the polyneuropathy of
hereditary transthyretin-mediated amyloidosis in adults. Subsequent to
this approval, the USPTO received patent term restoration applications
for TEGSEDI (U.S. Patent Nos. 8,101,743; 9,061,044; 9,399,774) from
Ionis Pharmaceuticals, Inc. and the USPTO requested FDA's assistance in
determining the patents' eligibility for patent term restoration. In,
letters dated October 29, 2019, and November 29, 2019, FDA advised the
USPTO that this human drug product had undergone a regulatory review
period and that the approval of TEGSEDI 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
TEGSEDI is 2,158 days. Of this time, 1,824 days occurred during the
testing phase of the regulatory review period, while 334 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 9, 2012. FDA has verified the applicant's claim that the date
the investigational new drug application became effective was on
November 9, 2012.
2. The date the application was initially submitted with respect to
the human drug product under section 505 of the FD&C Act: November 6,
2017. FDA has verified the applicant's claim that the new drug
application (NDA) for TEGSEDI (NDA 211172) was initially submitted on
November 6, 2017.
3. The date the application was approved: October 5, 2018. FDA has
verified the applicant's claim that NDA 211172 was approved on October
5, 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 applications for patent extension,
this applicant seeks 526 days or 1,246 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 https://www.regulations.gov at
Docket Nos. 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.
Dated: March 17, 2023.
