[Docket No. FDA-2012-E-0162]
Determination of Regulatory Review Period for Purposes of Patent
Extension; LAVIV
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) has determined the
regulatory review period for LAVIV 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 biological 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
Policy, Food and Drug Administration, 10903 New Hampshire Ave., Bldg.

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 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 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 biological 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 biologic product
LAVIV (azficel-T). LAVIV is an autologous cellular product indicated
for improvement of moderate to severe
[[Page 13686]]
nasolabial fold wrinkles in adults. Subsequent to this approval, the
Patent and Trademark Office received a patent term restoration
application for LAVIV (U.S. Patent No. 5,591,444) from Fibrocell
Technologies, 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 August 10, 2012, FDA advised the Patent
and Trademark Office that this human biological product had undergone a
regulatory review period and that the approval of LAVIV 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
LAVIV is 3,338 days. Of this time, 2,500 days occurred during the
testing phase of the regulatory review period, while 838 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: May 3,
2002. FDA has verified the applicant's claim that the date the
investigational new drug application became effective was on May 3,
2002.
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): March 6, 2009. FDA has verified the
applicant's claim that the biologics license application (BLA) for
LAVIV (BLA 125348) was initially submitted on March 6, 2009.
3. The date the application was approved: June 21, 2011. FDA has
verified the applicant's claim that BLA 125348 was approved on June 21,
2011.
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 5 years 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 April 29, 2013. 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 August 27, 2013. 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. 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.
Dated: February 15, 2013.
