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 VerDate Aug<31>2005 17:17 May 01, 2008 Jkt 214001 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 TEKTURNA (aliskiren hemifumarate). TEKTURNA is indicated for treatment of hypertension. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for TEKTURNA (U.S. Patent No. 5,559,111) from Novartis Corporation, and the Patent and Trademark Office requested FDA’s assistance in determining this patent’s eligibility for patent term restoration. In a letter dated November 21, 2007, FDA advised the Patent and Trademark Office that this human drug product had undergone a regulatory review period and that the approval of TEKTURNA represented the first permitted commercial marketing or use of the product. Shortly, 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 TEKTURNA is 2,023 days. Of this time, 1,637 days occurred during the testing phase of the regulatory review period, while 386 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: August 22, 2001. FDA has verified the applicant’s claim that the date the investigational new drug application became effective was on August 22, 2001. 2. The date the application was initially submitted with respect to the human drug product under section 505(b) of the act: February 13, 2006. FDA has verified the applicant’s claim that the new drug application (NDA) for TEKTURNA (NDA 21–985) was initially submitted on February 13, 2006. PO 00000 Frm 00085 Fmt 4703 Sfmt 4703 24295 3. The date the application was approved: March 5, 2007. FDA has verified the applicant’s claim that NDA 21–985 was approved on March 5, 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 2,022 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 July 1, 2008. 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 29, 2008. 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.

Policy, Food and Drug Administration, 10903 New Hampshire Ave., Bldg.

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 TEKTURNA 
(aliskiren hemifumarate). TEKTURNA is indicated for treatment of 
hypertension. Subsequent to this approval, the Patent and Trademark 
Office received a patent term restoration application for TEKTURNA 
(U.S. Patent No. 5,559,111) from Novartis Corporation, and the Patent 
and Trademark Office requested FDA's assistance in determining this 
patent's eligibility for patent term restoration. In a letter dated 
November 21, 2007, FDA advised the Patent and Trademark Office that 
this human drug product had undergone a regulatory review period and 
that the approval of TEKTURNA represented the first permitted 
commercial marketing or use of the product. Shortly, 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 
TEKTURNA is 2,023 days. Of this time, 1,637 days occurred during the 
testing phase of the regulatory review period, while 386 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: 
August 22, 2001. FDA has verified the applicant's claim that the date 
the investigational new drug application became effective was on August 
22, 2001.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the act: February 13, 
2006. FDA has verified the applicant's claim that the new drug 
application (NDA) for TEKTURNA (NDA 21-985) was initially submitted on 
February 13, 2006.
    3. The date the application was approved: March 5, 2007. FDA has 
verified the applicant's claim that NDA 21-985 was approved on March 5, 
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 2,022 days of 
patent term extension.
    Anyone with knowledge that any of the dates as published are

by July 1, 2008. Furthermore, any interested person may petition FDA

sess., pp. 41-42, 1984.) Petitions should be in the format specified in 
21 CFR 10.30.
