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 Fusilev (levoleucovorin calcium), a folate analog. Levoleucovorin rescue is indicated after high-dose methotrexate therapy in osteosarcoma and is also indicated to diminish the toxicity and counteract the effects of impaired methotrexate elimination and/or inadvertent overdosage of folic acid antagonists. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for Fusilev (U.S. Patent No. 6,500,829) from the University of Strathclyde, and the Patent and Trademark Office requested FDA’s assistance in determining this patent’s eligibility for patent term restoration and that FDA determine the product’s regulatory review period. In a letter dated June 1, 2011, FDA advised the Patent and Trademark Office that this PO 00000 Frm 00032 Fmt 4703 Sfmt 4703 36927 human drug product had undergone a regulatory review period and that the approval of Fusilev represented the first permitted commercial marketing or use of the product. FDA has determined that the applicable regulatory review period for Fusilev is 6,993 days. Of this time, 703 days occurred during the testing phase of the regulatory review period, while 6,290 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 15, 1989. The applicant claims December 15, 1988, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was January 15, 1989, which was 30 days after FDA receipt of the IND. 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 18, 1990. The applicant claims December 14, 1990, as the date the new drug application (NDA) for FUSILEV (NDA 20–140) was initially submitted. However, FDA records indicate that NDA 20–140 was submitted on December 18, 1990. 3. The date the application was approved: March 7, 2008. FDA has verified the applicant’s claim that NDA 20–140 was approved on March 7, 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 797 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 22, 2011. 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 20, 2011. 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 E:\FR\FM\23JNN1.SGM 23JNN1 36928 Federal Register / Vol. 76, No. 121 / Thursday, June 23, 2011 / Notices ADDRESSES) electronic or written comments and written petitions.

FDA recently approved for marketing the human drug product BROVANA (arformoterol tartrate). BROVANA is indicated for the long term, twice daily (morning and evening) maintenance treatment of bronchoconstriction in patients with chronic obstructive pulmonary disease, including chronic bronchitis and emphysema. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for BROVANA (U.S. Patent No. 6,589,508) from Sepracor Inc. (now Sunovion Pharmaceuticals, Inc.), and the Patent and Trademark Office requested FDA’s assistance in determining this patent’s eligibility for patent term restoration and that FDA determine the product’s regulatory review period. In a letter dated June 1, 2011, FDA advised the Patent and Trademark Office that this human drug product had undergone a regulatory review period and that the approval of BROVANA represented the first permitted commercial marketing or use of the product.

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 Fusilev 
(levoleucovorin calcium), a folate analog. Levoleucovorin rescue is 
indicated after high-dose methotrexate therapy in osteosarcoma and is 
also indicated to diminish the toxicity and counteract the effects of 
impaired methotrexate elimination and/or inadvertent overdosage of 
folic acid antagonists. Subsequent to this approval, the Patent and 
Trademark Office received a patent term restoration application for 
Fusilev (U.S. Patent No. 6,500,829) from the University of Strathclyde, 
and the Patent and Trademark Office requested FDA's assistance in 
determining this patent's eligibility for patent term restoration and 
that FDA determine the product's regulatory review period. In a letter 
dated June 1, 2011, FDA advised the Patent and Trademark Office that 
this human drug product had undergone a regulatory review period and 
that the approval of Fusilev represented the first permitted commercial 
marketing or use of the product.
    FDA has determined that the applicable regulatory review period for 
Fusilev is 6,993 days. Of this time, 703 days occurred during the 
testing phase of the regulatory review period, while 6,290 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 15, 1989. The applicant claims December 15, 1988, as 
the date the investigational new drug application (IND) became 
effective. However, FDA records indicate that the IND effective date 
was January 15, 1989, which was 30 days after FDA receipt of the IND.
    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 
18, 1990. The applicant claims December 14, 1990, as the date the new 
drug application (NDA) for FUSILEV (NDA 20-140) was initially 
submitted. However, FDA records indicate that NDA 20-140 was submitted 
on December 18, 1990.
    3. The date the application was approved: March 7, 2008. FDA has 
verified the applicant's claim that NDA 20-140 was approved on March 7, 
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 797 days of 
patent term extension.
    Anyone with knowledge that any of the dates as published are
