Determination of Regulatory Review Period for Purposes of Patent 
Extension; BRILINTA

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for BRILINTA and is publishing this notice of 
that determination as required by law. FDA has made the determination 
because of the submission of applications to the Director of Patents 
and Trademarks, Department of Commerce, for the extension of a patent 
which claims that human drug product.

ADDRESSES: Submit electronic comments to http://www.regulations.gov. 
Submit written petitions (two copies are required) and written comments 
to the Division of Dockets Management (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

Spring, MD 20993-0002, 301-796-7900.

SUPPLEMENTARY INFORMATION: 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 Patents and 
Trademarks 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 BRILINTA 
(ticagrelor). BRILINTA is indicated to reduce the rate of thrombotic 
cardiovascular events in patients with acute coronary syndrome. 
Subsequent to this approval, the Patent and Trademark Office received 
patent term restoration applications for BRILINTA (U.S. Patent Nos. 
6,525,060; 6,251,910; 7,250,419; and 7,265,124) from AstraZeneca UK 
Limited, and the Patent and Trademark Office requested FDA's assistance 
in determining this patent's eligibility for patent term restoration. 
In a letter dated

[[Page 24445]]

August 7, 2012, FDA advised the Patent and Trademark Office that this 
human drug product had undergone a regulatory review period and that 
the approval of BRILINTA represented the first permitted commercial 
marketing or use of the product. Thereafter, the Patent and Trademark 
Office requested that FDA determine the product's regulatory review 
period.
    FDA has determined that the applicable regulatory review period for 
BRILINTA is 2,976 days. Of this time, 2,364 days occurred during the 
testing phase of the regulatory review period, while 612 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 (the FD&C Act) (21 U.S.C. 355(i)) became 
effective: May 29, 2003. FDA has verified the applicant's claim that 
the date the investigational new drug application became effective was 
on May 29, 2003.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the FD&C Act: November 
16, 2009. FDA has verified the applicant's claim that the new drug 
application (NDA) for BRILINTA (NDA 22-433) was submitted on November 
16, 2009.
    3. The date the application was approved: July 20, 2011. FDA has 
verified the applicant's claim that NDA 22-433 was approved on July 20, 
2011.
    This determination of the regulatory review period establishes the 
maximum potential length of a patent extension. However, the Patent and 
Trademark Office applies several statutory limitations in its 
calculations of the actual period for patent extension. In its 
applications for patent extension, this applicant seeks 1,014 days, 
1,032 days, or 1,794 days of patent term extension.
    Anyone with knowledge that any of the dates as published are 
incorrect may submit to the Division of Dockets Management (see 
ADDRESSES) either electronic or written comments and ask for a 
redetermination by June 30, 2014. Furthermore, any interested person 
may petition FDA for a determination regarding whether the applicant 
for extension acted with due diligence during the regulatory review 
period by October 27, 2014. To meet its burden, the petition must 
contain sufficient facts to merit an FDA investigation. (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.
    Interested persons may submit to the Division of Dockets Management 
(see ADDRESSES) electronic or written comments and written or 
electronic petitions. It is only necessary to send one set of comments. 
Identify comments with the docket number found in brackets in the 
heading of this document. If you submit a written petition, two copies 
are required. A petition submitted electronically must be submitted to 
http://www.regulations.gov, Docket No. FDA-2013-S-0610.
    Comments and petitions that have not been made publicly available 
on http://www.regulations.gov may be viewed in the Division of Dockets 
Management between 9 a.m. and 4 p.m., Monday through Friday.

    Dated: April 24, 2014.

Assistant Commissioner for Policy.
