Determination of Regulatory Review Period for Purposes of Patent 
Extension; STRATTERA

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for STRATTERA 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 
that claims that human drug product.

ADDRESSES: Submit written comments and petitions to the Division of 
Dockets Management (HFA-305), Food and Drug Administration, 5630

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 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 
STRATTERA (atomoxetine hydrochloride). STRATTERA is indicated for the 
treatment of attention-deficit/hyperactivity disorder. Subsequent to 
this approval, the Patent and Trademark Office received a patent term 
restoration application for STRATTERA (U.S. Patent No. 5,658,590,) from 
Eli Lilly & 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 July 16, 2003, FDA advised the Patent 
and Trademark Office that this human drug product had undergone a 
regulatory review period and that the approval of STRATTERA 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 
STRATTERA is 7,718 days. Of this time, 7,307 days occurred during the 
testing phase of the regulatory review period, while 411 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: 
October 11, 1981. FDA has verified the applicant's claim that the date 
the investigational new drug application became effective was on 
October 11, 1981.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the act: October 12, 
2001. FDA has verified the applicant's claim that the new drug 
application (NDA) for STRATTERA (NDA 21-411) was initially submitted on 
October 12, 2001.
    3. The date the application was approved: November 26, 2002. FDA 
has verified the applicant's claim that NDA 21-411 was approved on 
November 26, 2002.
    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 685 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 comments and ask for a redetermination by February 
2, 2004. 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 June 1, 2004. 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.
