Determination of Regulatory Review Period for Purposes of Patent 
Extension; Xience Prime Ll Everolimus Eluting Coronary Stent System

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for Xience Prime Ll Everolimus Eluting 
Coronary Stent System 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 the U.S. 
Patent and Trademark Office (USPTO), Department of Commerce, for the 
extension of a patent which claims that medical device.

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 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 USPTO 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 has approved for marketing the medical device Xience Prime Ll 
Everolimus Eluting Coronary Stent System. Xience Prime Ll Everolimus 
Eluting Coronary Stent System is indicated for improving coronary 
luminal diameter in patients with symptomatic heart disease due to de 
novo native coronary artery lesions (length <= 32 millimeters (mm)) 
with reference vessel diameters of >=2.25 mm to <= 4.25 mm. Subsequent 
to this approval, the USPTO received a patent term restoration 
application for Xience Prime Ll Everolimus Eluting Coronary Stent 
System (U.S. Patent No. 5,514,154) from Abbott Cardiovascular Systems 
Inc., and the USPTO requested FDA's assistance in determining this 
patent's eligibility for patent term restoration. In a letter dated 
March 4, 2013, FDA advised the USPTO that this medical device had 
undergone a regulatory review period and that the approval of Xience 
Prime Ll Everolimus Eluting Coronary Stent System represented the first 
permitted commercial marketing or use of the product. Thereafter, the 
USPTO requested that the FDA determine the product's regulatory review 
period.
    FDA has determined that the applicable regulatory review period for 
Xience Prime Ll Everolimus Eluting Coronary Stent System is 890 days. 
Of this time, 694 days occurred during the testing phase of the 
regulatory review period, while 196 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 FD&C Act) (21 U.S.C. 360j(g)) involving 
this device became effective: May 27, 2009. FDA has verified the 
applicant's claim that the date the investigational device exemption 
(IDE) required under section 520(g) of the FD&C Act for human tests to 
begin became effective May 27, 2009.
    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): April 20, 2011. The applicant claims October 28, 
2010, as the date the premarket approval application (PMA) for Xience 
Prime Ll Everolimus Eluting Coronary Stent System (PMA P110019) was 
initially submitted. However, FDA records indicate that PMA P110019 was 
submitted in full on April 20, 2011.
    3. The date the application was approved: November 1, 2011. FDA has 
verified the applicant's claim that PMA P110019 was approved on 
November 1, 2011.
    This determination of the regulatory review period establishes the 
maximum potential length of a patent extension. However, the USPTO 
applies several statutory limitations in its calculations of the actual 
period for patent extension. In its application for patent extension, 
this applicant seeks 630 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 August 11, 2014. 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 December 8, 2014. 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 or 
electronic petitions. It is only necessary to send one set of comments. 
Identify comments with the docket number found in brackets in the 
heading of this document. If you submit a written petition, two copies 
are required. A petition submitted electronically must be submitted to 
http://www.regulations.gov, Docket No. FDA-2013-S-0610. Comments and 
petitions that have not been made publicly available on http://www.regulations.gov may be viewed in the Division of Dockets Management 
between 9 a.m. and 4 p.m., Monday through Friday.
