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

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for TEFLARO 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 patents 
which claim 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 TEFLARO 
(ceftaroline fosamil). TEFLARO is indicated for the treatment of the 
following infections caused by designated susceptible bacteria: Acute 
bacterial skin and skin structure infections; and community-acquired 
bacterial pneumonia. Subsequent to this approval, the Patent and 
Trademark Office received patent term restoration applications for 
TEFLARO (U.S. Patent Nos. 6,417,175 and 6,906,055) from Takeda 
Pharmaceutical Company Limited, and the Patent and Trademark Office 
requested FDA's assistance in determining the patents' eligibility for 
patent term restoration. In a letter dated June 8, 2011, FDA advised 
the Patent and Trademark Office that this human drug product had 
undergone a regulatory review period and that the approval of TEFLARO 
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 
TEFLARO is 2,118 days. Of this time, 1,814 days occurred during the 
testing phase of the regulatory review period, while 304 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 12, 2005. FDA has verified the applicant's claim 
that the date the investigational new drug application became effective 
was on January 12, 2005.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the FD&C Act: December 
30, 2009. FDA has verified the applicant's claim that the new drug 
application (NDA) for TEFLARO (NDA 200-327) was submitted on December 
30, 2009.
    3. The date the application was approved: October 29, 2010. FDA has 
verified the applicant's claim that NDA 200-327 was approved on October 
29, 2010.
    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 
applications for patent extension, this applicant seeks 1,049 days or 
1,211 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 5, 2012. 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 3, 2012. 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. 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.
