FOR FURTHER INFORMATION CONTACT: Beverly Friedman, Office of Regulatory Policy (HFD–7), Food and Drug Administration, 5600 Fishers Lane, Rockville, MD 20857, 301–594–2041. 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 REVLIMID (lenalidomide). REVLIMID is indicated for treatment of patients with transfusion-dependent anemia due to Low- or Intermediate-1-risk myelodysplastic syndromes associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for REVLIMID (U.S. Patent No. 5,635,517) from Celgene Corp., and the Patent and Trademark Office requested FDA’s assistance in determining this patent’s VerDate Aug<31>2005 15:30 Mar 23, 2007 Jkt 211001 eligibility for patent term restoration. In a letter dated June 14, 2006, FDA advised the Patent and Trademark Office that this human drug product had undergone a regulatory review period and that the approval of REVLIMID 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 REVLIMID is 2,069 days. Of this time, 1,804 days occurred during the testing phase of the regulatory review period, while 265 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: April 30, 2000. The applicant claims May 1, 2000, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was April 30, 2000, 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 act: April 7, 2005. FDA has verified the applicant’s claim that the new drug application (NDA) for REVLIMID (NDA 21–880) was initially submitted on April 7, 2005. 3. The date the application was approved: December 27, 2005. FDA has verified the applicant’s claim that NDA 21–880 was approved on December 27, 2005. 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 1,166 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 25, 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 September 24, 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., PO 00000 Frm 00048 Fmt 4703 Sfmt 4703 14119 pp. 41–42, 1984.) Petitions should be in the format specified in 21 CFR 10.30.

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 animal drug products, the 
testing phase begins on the earlier date when either a major 
environmental effects test was initiated for the drug or when an 
exemption under section 512(j) of the Federal Food, Drug, and Cosmetic 
Act (21 U.S.C. 360b(j)) became effective and runs until the approval 
phase begins. The approval phase starts with the initial submission of 
an application to market the animal 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 animal 
drug product will include all of the testing phase and approval phase 
as specified in 35 U.S.C. 156(g)(4)(B).
    FDA approved for marketing the animal drug product PREVICOX 
(firocoxib). PREVICOX is indicated for control of pain and inflammation 
associated with osteoarthritis in dogs. Subsequent to this approval, 
the Patent and Trademark Office received a patent term restoration 
application for PREVICOX (U.S. Patent No. 5,981,576) from Merck Frosst 
Canada & Co., 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 14, 2006, FDA advised the Patent 
and Trademark Office that this animal drug product had undergone a 
regulatory review period and that the approval of PREVICOX 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 
PREVICOX is 2,216 days. Of this time, 2,118 days occurred during the 
testing phase of the regulatory review period, while 98 days occurred 
during the approval phase. These periods of time were derived from the 
following dates:
    1. The date an exemption under section 512(j) of the Federal Food, 
Drug, and Cosmetic Act (the act) (21 U.S.C. 360b(j)) involving this 
animal drug product became effective: June 29, 1998. FDA has verified 
the applicant's claim that the date the investigational new animal drug 
application (INAD) became effective was on June 29, 1998.
    2. The date the application was initially submitted with respect to 
the animal drug product under section 512(b) of the act: April 15, 
2004. FDA has verified the applicant's claim that the new animal drug 
Application (NADA) for PREVICOX (NADA 141-230) was initially submitted 
on April 15, 2004.
    3. The date the application was approved: July 21, 2004. FDA has 
verified the applicant's claim that NADA 141-230 was approved on July 
21, 2004.
    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 650 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 25, 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 September 24, 
2007. To meet its burden, the petition must contain sufficient facts to

be identified with the docket number found in brackets in the heading
