Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) has determined the regulatory review period for ELVITEGRAVIR (as a component of STRIBILD) 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 the U.S. Patent and Trademark Office (USPTO), Department of Commerce, for the extension of a patent which claims that human drug product.

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 USPTO 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 has approved for marketing the human drug product ELVITEGRAVIR (as a component of STRIBILD (cobicistat/emtricitabine/ELVITEGRAVIR/tenofovir disoproxil fumarate)). STRIBILD is indicated as a complete regimen for the treatment of HIV-1 infection in adults who are antiretroviral treatment-naive. Subsequent to this approval, the USPTO received a patent term restoration application for ELVITEGRAVIR (as a component of STRIBILD) (U.S. Patent No. 7,176,220) from Japan Tobacco Inc., and the USPTO requested FDA's assistance in determining this patent's eligibility for patent term restoration. In a letter dated July 10, 2013, FDA advised the USPTO that this human drug product had undergone a regulatory review period and that the approval of STRIBILD represented the first permitted commercial marketing or use of the ELVITEGRAVIR product. Thereafter, the USPTO requested that FDA determine the product's regulatory review period.
FDA has determined that the applicable regulatory review period for ELVITEGRAVIR (as a component of STRIBILD) is 2,666 days. Of this time, 2,360 days occurred during the testing phase of the regulatory review period, while 306 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: May 12, 2005. The applicant claims May 18, 2005, as the date the investigational new drug application (IND) for ELVITEGRAVIR became effective. However, FDA records indicate that the IND effective date was May 12, 2005, which was the date the IND sponsor was notified that clinical trials may proceed.
2. The date the application was initially submitted with respect to the human drug product under section 505(b) of the FD&C Act: October 27, 2011. The applicant claims October 26, 2011, as the date the new drug application (NDA) for STRIBILD (NDA 203-100) was initially submitted. However, FDA records indicate that NDA 203-100 was submitted on October 27, 2011.
3. The date the application was approved: August 27, 2012. FDA has verified the applicant's claim that NDA 203-100 was approved on August 27, 2012.
This determination of the regulatory review period establishes the maximum potential length of a patent extension. However, the USPTO applies several statutory limitations in its calculations of the actual period for patent extension. In its application for patent extension, this applicant seeks 1,021 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 June 12, 2015. 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 13, 2015. 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 ADDRESSES) electronic or written comments and written or electronic Start Printed Page 19672petitions. It is only necessary to send one set of comments. Identify comments with the docket number found in brackets in the heading of this document. If you submit a written petition, two copies are required. A petition submitted electronically must be submitted to http://www.regulations.gov, Docket No. FDA-2013-S-0610. Comments and petitions that have not been made publicly available on http://www.regulations.gov may be viewed in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
