Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) has determined the regulatory review period for PALLADIA 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 which claims that animal drug product.

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 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 (the FD&C 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 an 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 has approved for marketing the animal drug product PALLADIA (toceranib phosphate). PALLADIA is indicated for the treatment of Patnaik grade II or III, recurrent, cutaneous mast cell tumors with or without regional lymph node involvement in dogs. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for PALLADIA (U.S. Patent No. 6,573,293) from Sugen, Inc., and Pharmacia & Upjohn Company LLC, and the Patent and Trademark Office requested FDA's assistance in determining this patent's eligibility for patent term restoration. In a letter dated May 3, 2011, FDA advised the Patent and Trademark Office that this animal drug product had undergone a regulatory review period and that the approval of PALLADIA represented the first permitted commercial marketing or use of the product. Thereafter, the Patent and Trademark Office requested that the FDA determine the product's regulatory review period.
FDA has determined that the applicable regulatory review period for PALLADIA is 2,711 days. Of this time, 2,681 days occurred during the testing phase of the regulatory review period, while 30 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: December 21, 2001. The applicant claims November 23, 2001, as the date the investigational new animal drug application (INAD) became effective. However, Food and Drug Administration (FDA) records indicate that the INAD effective date was December 21, 2001, which was the received date of the first submission that includes a study with substantial data (submission of a major health test) or the first submission containing a Notice of Claimed Investigational Exemption.
2. The date the application was initially submitted with respect to the animal drug product under section 512 of the FD&C Act (21 U.S.C. 360b): April 23, 2009. The applicant claims April 22, 2009, as the date the new animal drug application (NADA) for Palladia (NADA 141-295) was initially submitted. However, FDA records indicate that NADA 141-295 was submitted on April 23, 2009.
3. The date the application was approved: May 22, 2009. FDA has verified the applicant's claim that NADA 141-295 was approved on May 22, 2009.
This determination of the regulatory review period establishes the maximum potential length of a patent extension. However, the 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 Start Printed Page 27880applicant seeks 827 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 July 14, 2014. 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 November 12, 2014. 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 petitions. 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.
