[Docket No. FDA-2010-E-0400]
Determination of Regulatory Review Period for Purposes of Patent
Extension; VPRIV
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) has determined the
regulatory review period for VPRIV 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 human drug product.
ADDRESSES: Submit electronic comments to http://www.regulations.gov.
Submit written petitions along with three copies and written comments
to the Division of Dockets Management (HFA-305), Food and Drug
Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852.
FOR FURTHER INFORMATION CONTACT: Beverly Friedman, Office of Regulatory

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 recently approved for marketing the human drug product VPRIV
(velaglucerase alfa). VPRIV is indicated for long-term enzyme
replacement therapy for pediatric and adult patients with type 1
Gaucher Disease. Subsequent to this approval, the Patent and Trademark
Office received a patent term restoration application for VPRIV (U.S.
Patent No. 7,138,262) from Shire Human Genetic Therapies, Inc., 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 30, 2010, FDA advised the Patent and Trademark Office
that this human drug product had undergone a regulatory review period
and that the approval of VPRIV 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
VPRIV is 2,221 days. Of this time, 2,041 days occurred during the
testing phase of the regulatory review period, while 180 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: January 30, 2004. The applicant claims May 20, 2004, as the
date the investigational new drug application (IND) became effective.
However, FDA records indicate that the IND effective date was January
30, 2004, 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: August 31,
2009. FDA has verified the applicant's claim that the new drug
application (NDA) for VPRIV (NDA 22-575) was initially submitted on
August 31, 2009.
3. The date the application was approved: February 26, 2010. FDA
has verified the applicant's claim that NDA 22-575 was approved on
February 26, 2010.
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 687 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 May 20, 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 September 19, 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 http://www.regulations.gov may be viewed in the Division of Dockets
Management between 9 a.m. and 4 p.m., Monday through Friday.
