# AGENCY:

# SUMMARY:

                        The Food and Drug Administration (FDA) has determined the regulatory review period for ANGIOMAX 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                               ( print page 78715)                            Director of Patents and Trademarks, Department of Commerce, for the extension of a patent which claims that human drug product.

# SUPPLEMENTARY 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 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 approved for marketing the human drug product ANGIOMAX (bivalirudin). ANGIOMAX is indicated for use as an anticoagulant in patients with unstable angina undergoing percutaneous transluminal coronary angioplasty. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for ANGIOMAX (U.S. Patent No. 5,196,404) from The Medicines Company, and the Patent and Trademark Office requested FDA's assistance in determining this patent's eligibility for patent term restoration. In a letter dated September 6, 2001, FDA advised the Patent and Trademark Office that this human drug product had undergone a regulatory review period, that the approval of ANGIOMAX represented the first permitted commercial marketing or use of the product, and that the patent term restoration application was untimely within the meaning of 35 U.S.C. section 156(d)(1).

                    On August 3, 2010, in                     *The Medicines Company*                     v.                     *David Kappos et al.,*                     Civil Action No. 01:10-cv-286, the United States District Court for the Eastern District of Virginia, Alexandria Division, ordered the United States Patent and Trademark Office to consider The Medicines Company's patent term restoration application for ANGIOMAX to have been timely filed. 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 ANGIOMAX is 3,665 days. Of this time, 2,576 days occurred during the testing phase of the regulatory review period, while 1,089 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 5, 1990. The applicant claims November 2, 1990, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was December 5, 1990, 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 FD&C Act:*                     December 23, 1997. FDA has verified the applicant's claim that the new drug application (NDA) for ANGIOMAX (NDA 20-873) was submitted on December 23, 1997.                

                    3.                     *The date the application was approved:*                     December 15, 2000. FDA has verified the applicant's claim that NDA 20-873 was approved on December 15, 2000.                

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 1,773 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 February 14, 2011. 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 14, 2011. 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 petitions. It is only necessary to send one set of comments. It is no longer necessary to send three copies of mailed comments. However, if you submit a written petition, you must submit three copies of the petition. Identify comments with the docket number found in brackets in the heading of this document.                

Comments and petitions that have not been made publicly available on regulations.gov may be viewed in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
