          - [Docket No. 2002E-0156]

# AGENCY:

Food and Drug Administration, HHS.

# ACTION:

Notice.

# SUMMARY:

The Food and Drug Administration (FDA) has determined the regulatory review period for GALILEO INTRAVASCULAR RADIOTHERAPY 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 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.fda.gov/​dockets/​ecomments*.

# 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, GALILEO INTRAVASCULAR RADIOTHERAPY SYSTEM. GALILEO INTRAVASCULAR RADIOTHERAPY SYSTEM is indicated to deliver beta radiation to the site of successful percutaneous coronary intervention (PCI) for the treatment of in-stent restenosis in native coronary arteries with discrete lesions ≤ 47 millimeters (mm) in a reference vessel diameter 2.4 mm to 3.7 mm. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for GALILEO INTRAVASCULAR RADIOTHERAPY SYSTEM (U.S. Patent No. 5,199,939) from Guidant 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 October 31, 2002, FDA advised the Patent and Trademark Office that this medical device had undergone a regulatory review period and that the approval of GALILEO INTRAVASCULAR RADIOTHERAPY SYSTEM 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 GALILEO INTRAVASCULAR RADIOTHERAPY SYSTEM is 1,523 days. Of this time, 1,203 days occurred during the testing phase of the regulatory review period, while 320 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*: September 3, 1997. 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 September 3, 1997.                

                    2.                     *The date the application was initially submitted with respect to the device under section 515 of the act (21 U.S.C. 360e)*: December 18, 2000. The applicant claims March 13, 2000, as the date the premarket approval application (PMA) for GALILEO INTRAVASCULAR RADIOTHERAPY SYSTEM (PMA P000052) was initially submitted. However, FDA records indicate that PMA P000052 was completely submitted on December 18, 2000.                

                    3.                     *The date the application was approved*: November 2, 2001. FDA has verified the applicant's claim that PMA P000052 was approved on November 2, 2001.                

                    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.                           ( print page 28499)                        In its application for patent extension, this applicant seeks 1,062 days of patent term extension.                

                    Anyone with knowledge that any of the dates as published is incorrect may submit to the Division of Dockets Management (see                     **ADDRESSES**                    ) written or electronic comments and ask for a redetermination by July 20, 2007. 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 November 19, 2007. 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: May 7, 2007.
