Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) has determined the regulatory review period for IXINITY and is publishing this notice of that determination as required by law. FDA has made the determination because of the submission of applications 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 biological product.
Anyone with knowledge that any of the dates as published (see the SUPPLEMENTARY INFORMATION section) are incorrect may submit either electronic or written comments and ask for a redetermination by January 30, 2017. 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 May 30, 2017. See “Petitions” in the SUPPLEMENTARY INFORMATION section for more information.

Start Supplemental 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 biological products, the testing phase begins when the exemption to permit the clinical investigations of the biological becomes effective and runs until the approval phase begins. The approval phase starts with the initial submission of an application to market the human biological product and continues until FDA grants permission to market the biological product. Although only a portion of a regulatory review period may count toward the actual amount of extension that the Director of the 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 biological 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 biologic product IXINITY (Coagulation Factor IX (recombinant)). IXINITY is indicated for control and prevention of bleeding episodes and for perioperative management, in adults and children ≥12 years of age with hemophilia B. Subsequent to this approval, the USPTO received patent term restoration applications for IXINITY (U.S. Patent Nos. 7,645,602 and 8,603,823) from the University of North Carolina at Chapel Hill, and the USPTO requested FDA's assistance in determining the patents' eligibility for patent term restoration. In a letter dated March 10, 2016, FDA advised the USPTO that this human biological product had undergone a regulatory review period and that the approval of IXINITY represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product's regulatory review period.
II. Determination of Regulatory Review Period
FDA has determined that the applicable regulatory review period for IXINITY is 2,437 days. Of this time, 1,318 days occurred during the testing phase of the regulatory review period, while 1,119 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 (21 U.S.C. 355(i)) became effective: August 28, 2008. FDA has verified the applicant's claim that the date the investigational new drug application became effective was on August 28, 2008.
2. The date the application was initially submitted with respect to the human biological product under section 351 of the Public Health Service Act (42 U.S.C. 262): April 6, 2012. The applicant claims April 5, 2012, as the date the biologics license application (BLA) for IXINITY (BLA 125426) was initially submitted. However, FDA records indicate that BLA 125426 was submitted on April 6, 2012.
3. The date the application was approved: April 29, 2015. FDA has verified the applicant's claim that BLA 125426 was approved on April 29, 2015.
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 applications for patent extension, this applicant seeks 1,526 days or 505 days of patent term extension.
Anyone with knowledge that any of the dates as published are incorrect may submit either electronic or written comments and ask for a redetermination (see DATES). 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. To meet its burden, the petition must be timely (see DATES) and 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.
Submit petitions electronically to https://www.regulations.gov at Docket No. FDA-2013-S-0610. Submit written petitions (two copies are required) to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
