SUMMARY: The Food and Drug Administration (FDA) has determined the
regulatory review period for XARELTO and is publishing this notice of

and Trademarks, Department of Commerce, for the extension of a patent
which claims that human drug product.

Submit written petitions (two copies are required) and written comments

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 has approved for marketing the human drug product XARELTO
(rivaroxaban). XARELTO is indicated for the prophylaxis of deep vein
thrombosis, which may lead to pulmonary embolism in patients undergoing
knee or hip replacement surgery. Subsequent to this approval, the
Patent and Trademark Office received a patent term restoration
application for XARELTO (U.S. Patent No. 7,157,456) from Bayer Pharma
Aktiengesellschaft, 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 9, 2012, FDA advised the Patent and
Trademark Office that this human drug product had undergone a
regulatory review period and that the approval of XARELTO 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
XARELTO is 3,291 days. Of this time, 2,222 days occurred during the
testing phase of the regulatory review period, while 1,069 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: June 29, 2002. The applicant claims June 30, 2002, as the
date the investigational new drug application (IND) became effective.
However, FDA records indicate that the IND effective date was June 29,
2002, 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: July 28,
2008. FDA has verified the applicant's claim that the new drug
application (NDA) for XARELTO (NDA 22-406) was submitted on July 28,
2008.
3. The date the application was approved: July 1, 2011. FDA has
verified the applicant's claim that NDA 22-406 was approved on July 1,
2011.
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 applicant seeks 1,354 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 28, 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 25, 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.
Dated: May 21, 2014.
