Background 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 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 KEVZARA (sarilumab). KEVZARA is indicated for treatment of adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response or intolerance to one or more disease-modifying antirheumatic drugs. Subsequent to this approval, the USPTO received patent term restoration applications for KEVZARA (U.S. Patent Nos. 7,582,298 and 8,568,721) from Regeneron Pharmaceuticals, Inc., and the USPTO requested FDA’s assistance in determining the patents’ eligibility for patent term restoration. In a letter dated February 6, 2018 (revised), FDA advised the USPTO that this human biological product had undergone a regulatory review period and that the approval of KEVZARA represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product’s regulatory review period. 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 II. Determination of Regulatory Review Period FDA has determined that the applicable regulatory review period for KEVZARA is 3,478 days. Of this time, 2,907 days occurred during the testing phase of the regulatory review period, while 571 days occurred during the Dockets Management Staff between 9 a.m. and 4 p.m., Monday through Friday. • Confidential Submissions—To submit a comment with confidential information that you do not wish to be made publicly available, submit your comments only as a written/paper submission.

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 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 KEVZARA
(sarilumab). KEVZARA is indicated for treatment of adult patients with
moderately to severely active rheumatoid arthritis who have had an
inadequate response or intolerance to one or more disease-modifying
antirheumatic drugs. Subsequent to this approval, the USPTO received
patent term restoration applications for KEVZARA (U.S. Patent Nos.
7,582,298 and 8,568,721) from Regeneron Pharmaceuticals, Inc., and the
USPTO requested FDA's assistance in determining the patents'
eligibility for patent term restoration. In a letter dated February 6,
2018 (revised), FDA advised the USPTO that this human biological
product had undergone a regulatory review period and that the approval
of KEVZARA 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
KEVZARA is 3,478 days. Of this time, 2,907 days occurred during the
testing phase of the regulatory review period, while 571 days occurred
during the

[[Page 61645]]

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 (21 U.S.C. 355(i)) became effective: November
15, 2007. FDA has verified the applicant's claim that the date the
investigational new drug application became effective was on November
15, 2007.
2. The date the application was initially submitted with respect to
the human biological product under section 351 of the Public Health
Service Act (42 U.S.C. 262): October 30, 2015. FDA has verified the
applicant's claim that the biologics license application (BLA) for
KEVZARA (BLA 761037) was initially submitted on October 30, 2015.
3. The date the application was approved: May 22, 2017. FDA has
verified the applicant's claim that BLA 761037 was approved on May 22,
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,
this applicant seeks 1,234 or 937 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,
