[Docket No. FDA-2008-E-0308]

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

AGENCY:  Food and Drug Administration, HHS.

ACTION:  Notice.

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

SUMMARY:  The Food and Drug Administration (FDA) has determined the 
regulatory review period for ENDEAVOR 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 medical device.

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 http://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 medical devices, the testing 
phase begins with a clinical investigation of the device and runs until 
the approval phase begins. The approval phase starts with the initial 
submission of an application to market the device and continues until 
permission to market the device is granted. 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 (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 medical device will include 
all of the testing phase and approval phase as specified in 35 U.S.C. 
156(g)(3)(B).
    FDA recently approved for marketing the medical device, ENDEAVOR 
(Zotarolimus-Eluting Coronary Stent System). ENDEAVOR is indicated for 
improving coronary luminal diameter in patients with ischemic heart 
disease due to de novo lesions of length <=27 millimeters (mm) in 
native coronary arteries with reference vessel diameters of >=2.5 mm to 
<=3.5 mm. Subsequent to this approval, the Patent and Trademark Office 
received a patent term restoration application for ENDEAVOR (U.S. 
Patent No. 5,624,411) from Medtronic, Inc., and the Patent and 
Trademark Office requested FDA's assistance in determining this 
patent's eligibility for patent term restoration. In a letter dated 
June 19, 2008, FDA advised the Patent and Trademark Office that this 
medical device had undergone a regulatory review period and that the 
approval of ENDEAVOR 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 
ENDEAVOR is 1,507 days. Of this time, 1,068 days occurred during the 
testing phase of the regulatory review period, while 439 days occurred 
during the approval phase. These periods of time were derived from the 
following dates:
    1. The date an exemption under section 520(g) of the Federal Food, 
Drug, and Cosmetic Act (the act) (21 U.S.C. 360j(g)) involving this 
device became effective: December 19, 2003. FDA has verified the 
applicant's claim that the date the investigational device exemption 
(IDE) required under section 520(g) of the act for human tests to begin 
became effective was December 19, 2003.
    2. The date an application was initially submitted with respect to 
the device under section 515 of the Federal Food, Drug, and Cosmetic 
Act (21 U.S.C. 360e): November 20, 2006. The applicant claims November 
16, 2006, as the date the premarket approval application (PMA) for 
ENDEAVOR (PMA P060033) was initially submitted. However, FDA records 
indicate that PMA P060033 was submitted on November 20, 2006.
    3. The date the application was approved: February 1, 2008. FDA has 
verified the applicant's claim that PMA P060033 was approved on 
February 1, 2008.
    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 954 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 4, 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 August 31, 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.

    Dated: February 17, 2009.
