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

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

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

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 biological products, the 
testing phase begins when the exemption to permit the clinical 
investigations of the biological 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 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 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 NULOJIX 
(belatacept). NULOJIX is indicated for prophylaxis of organ rejection 
in adult patients receiving a kidney transplant and is used in 
combination with basiliximab induction, mycophenolate mofetil, and 
corticosteroids. Subsequent to this approval, the Patent and Trademark 
Office received a patent term restoration application for NULOJIX (U.S. 
Patent No. 7,094,874) from Bristol-Myers Squibb Company, and the Patent 
and Trademark Office requested FDA's assistance in determining this 
patent's eligibility for patent term restoration. In a letter dated 
July 10, 2012, FDA advised the Patent and Trademark Office that this 
human biological product had undergone a regulatory review period and 
that the approval of NULOJIX 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 
NULOJIX is 4,479 days. Of this time, 3,764 days occurred during the 
testing phase of the regulatory review period, while 715 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 (21 U.S.C. 355(i)) became effective: March 13, 
1999. FDA has verified the applicant's claim that the date the 
investigational new drug application became effective was on March 13, 
1999.
    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): July 1, 2009. The applicant claims June 
30, 2009, as the date the biologics license application (BLA) for 
NULOJIX (BLA 125288) was initially submitted. However, FDA records 
indicate that BLA 125288 was submitted on July 1, 2009.
    3. The date the application was approved: June 15, 2011. FDA has 
verified the applicant's claim that BLA 125288 was approved on June 15, 
2011.
    This determination of the regulatory review period establishes the 
maximum potential length of a patent extension. However, the U.S. 
Patent and Trademark Office applies several statutory limitations in 
its calculations of the actual period for patent extension. In its 
application for patent extension,

[[Page 18037]]

this applicant seeks 789 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 May 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 September 29, 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: March 25, 2014.
