[Docket No. FDA-2007-E-0164]
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

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.
