Determination of Regulatory Review Period for Purposes of Patent 
Extension; ALTABAX OINTMENT

AGENCY:  Food and Drug Administration, HHS.

ACTION:  Notice.

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

SUMMARY:  The Food and Drug Administration (FDA) has determined the 
regulatory review period for ALTABAX OINTMENT 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 written comments and petitions to the Division of 
Dockets Management (HFA-305), Food and Drug Administration, 5630 
Fishers Lane, rm. 1061, Rockville, MD 20852. Submit electronic comments 
to https://www.regulations.gov.

FOR FURTHER INFORMATION CONTACT:  Beverly Friedman, Office of 
Regulatory Policy, Food and Drug Administration, 10903 New Hampshire 
Ave., Bldg. 51, rm. 6222, Silver Spring, MD 20993-0002, 301-796-3602.

SUPPLEMENTARY INFORMATION: The Drug Price Competition and Patent Term 
Restoration Act of 1984 (Public Law 98-417) and the Generic Animal Drug 
and Patent Term Restoration Act (Public Law 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 human drug 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 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 ALTABAX 
OINTMENT (retapamulin). ALTABAX OINTMENT is indicated for the topical 
treatment of impetigo due to Staphylococcus aureus (methicillin-
susceptible isolates only) or Streptococcus pyogenes in patients aged 9 
months or older. Subsequent to this approval, the Patent and Trademark 
Office received a patent term restoration application for ALTABAX 
OINTMENT (U.S. Patent No. RE39,128E) from SmithKline Beecham P.L.C., 
and SmithKline Beecham Corp., and the Patent and Trademark Office 
requested FDA's assistance in determining this patent's eligibility for 
patent term restoration. In a letter dated April 28, 2008, FDA advised 
the Patent and Trademark Office that this human drug product had 
undergone a regulatory review period and that the approval of ALTABAX 
OINTMENT 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 
ALTABAX OINTMENT is 1,602 days. Of this time, 1,297 days occurred 
during the testing phase of the regulatory review period, while 305 
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 act) (21 U.S.C. 355(i)) became effective: 
November 24, 2002. FDA has verified the applicant's claim that the date 
the investigational new drug application became effective was on 
November 24, 2002.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the act: June 12, 2006. 
FDA has verified the applicant's claim that the new drug application 
(NDA) for ALTABAX OINTMENT (NDA 22-055) was initially submitted on June 
12, 2006.
    3. The date the application was approved: April 12, 2007. FDA has 
verified the applicant's claim that NDA 22-055 was approved on April 
12, 2007.
    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 833 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) written or electronic comments and ask for a redetermination 
by May 8, 2009. 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 8, 
2009. 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.
    Comments and petitions should be submitted to the Division of 
Dockets Management. Three copies of any mailed information are to be 
submitted, except that individuals may submit one copy. Comments are to 
be identified with the docket number found in brackets in the heading 
of this document. Comments and petitions may be seen in the Division of 
Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
