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

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for BEPREVE 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 drug product.

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

FOR FURTHER INFORMATION CONTACT: Beverly Friedman, Office of Regulatory 
Policy, Food and Drug Administration, 10903 New Hampshire Ave., Bldg.

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 recently approved for marketing the human drug product BEPREVE 
(bepotastine besilate). BEPREVE is indicated for the treatment of 
itching associated with allergic conjunctivitis. Subsequent to this 
approval, the Patent and Trademark Office received a patent term 
restoration application for BEPREVE (U.S. Patent No. 6,780,877) from 
Ube Industries, Ltd., and the Patent and Trademark Office requested 
FDA's assistance in determining this patent's eligibility for patent 
term restoration. In a letter dated March 3, 2010, FDA advised the 
Patent and Trademark Office that this human drug product had undergone 
a regulatory review period and that the approval of BEPREVE 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 
BEPREVE is 964 days. Of this time, 663 days occurred during the testing 
phase of the regulatory review period, while 301 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: January 20, 2007. The applicant claims January 19, 2007, as 
the date the investigational new drug application (IND) became 
effective. However, FDA records indicate that the IND effective date 
was January 20, 2007, 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: November 
12, 2008. FDA has verified the applicant's claim that the new drug 
application (NDA) 22-288 was submitted on November 12, 2008.
    3. The date the application was approved: September 8, 2009. FDA 
has verified the applicant's claim that NDA 22-288 was approved on 
September 8, 2009.
    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, this applicant seeks 631 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 February 7, 2011. 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 June 7, 2011. 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 petitions. 
It is only necessary to send one set of comments. It is no longer 
necessary to send three copies of mailed comments. However, if you 
submit a written petition, you must submit three copies

of the petition. Identify comments with the docket number found in 
brackets in the heading of this document. Comments and petitions that 
have not been made publicly available on regulations.gov may be viewed 
in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday 
through Friday.
