[Docket No. FDA-2009-E-0416]
Determination of Regulatory Review Period for Purposes of Patent
Extension; IXIARO
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) has determined the
regulatory review period for IXIARO 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 (Public Law 98-417) and the Generic Animal Drug
and Patent Term Restoration Act (Public Law 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
IXIARO (Japanese Encephalitis Virus, Vaccine Inactivated, Adsorbed).
IXIARO is indicated for active immunization for the prevention of
disease caused by Japanese encephalitis virus in persons 17 years of
age and older. Subsequent to this approval, the Patent and Trademark
Office received a patent term restoration application for IXIARO (U.S.
Patent No. 6,309,650) from Chiel Jedang Corp. and Walter Reed Army
Institute of Research, and the Patent and Trademark Office requested
FDA's assistance in determining this patent's eligibility for patent
term restoration. In a letter dated February 17, 2010, FDA advised the
Patent and Trademark Office that this human biological product had
undergone a regulatory review period and that the approval of IXIARO
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
IXIARO is 3,461 days. Of this time, 2,994 days occurred during the
testing phase of the regulatory review period, while 467 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: October 10,
1999. The applicant claims October 9, 1999, as the date the
investigational new drug application (IND) became effective. However,
FDA records indicate that the IND effective date was October 10, 1999,
which was 30 days after FDA receipt of the IND.
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): December 20, 2007. FDA has verified the
applicant's claim that the biologics license application (BLA) for
IXIARO (BLA B125280/0) was initially submitted on December 20, 2007.
3. The date the application was approved: March 30, 2009. FDA has
verified the applicant's claim that BLA B125280/0 was approved on March
30, 2009.
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 1,588 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 November 8, 2010. 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 March 8, 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
[[Page 54889]]
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.
Dated: August 13, 2010.
