SUPPLEMENTARY INFORMATION:

I. Background

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 animal drug products, the
testing phase begins on the earlier date when either a major
environmental effects test was initiated for the drug or when an
exemption under section 512(j) of the Federal Food, Drug, and Cosmetic
Act (FD&C Act) (21

[[Page 6034]]

U.S.C. 360b(j)) became effective and runs until the approval phase
begins. The approval phase starts with the initial submission of an
application to market the animal 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 USPTO 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 an animal drug product will
include all of the testing phase and approval phase as specified in 35
U.S.C. 156(g)(4)(B).
FDA has approved for marketing the animal drug product BRAVECTO
(fluralaner). BRAVECTO is indicated for treatment and control of flea
infestations (Ctenocephalides felis), and the treatment and control of
tick infestations (Ixodes scapularis (black legged tick), Dermacentor
variabilis (American dog tick), and Rhipicephalus sanguineus (brown dog
tick)) for 12 weeks in dogs and puppies 6 months of age and older, and
weighing 4.4 pounds or greater. It is also indicated for the treatment
and control of Amblyomma americanum (lone star tick) infestations for 8
weeks in dogs and puppies 6 months of age and older and weighing 4.4
pounds or greater. Subsequent to this approval, the USPTO received a
patent term restoration application for BRAVECTO (U.S. Patent No.
7,662,972) from Nissan Chemical Industries, Ltd., and the USPTO
requested FDA's assistance in determining this patent's eligibility for
patent term restoration. In a letter dated October 19, 2015, FDA
advised the USPTO that this animal drug product had undergone a
regulatory review period and that the approval of BRAVECTO represented
the first permitted commercial marketing or use of the product.
Thereafter, the USPTO requested that FDA determine the product's
regulatory review period.

II. Determination of Regulatory Review Period

FDA has determined that the applicable regulatory review period for
BRAVECTO is 1,017 days. Of this time, 979 days occurred during the
testing phase of the regulatory review period, while 38 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 FD&C Act (21
U.S.C. 355(i)) became effective: August 4, 2011. The applicant claims
February 19, 2010, as the date the investigational new animal drug
application (INAD) became effective. However, FDA records indicate that
the INAD effective date was August 4, 2011, which was the date a major
health or environmental effects test was begun or the date on which the
Agency acknowledged the filing of a notice of claimed investigational
exemption for a new animal drug, whichever was earlier.
2. The date the application was initially submitted with respect to
the animal drug product under section 512 of the FD&C Act: April 8,
2014. FDA has verified the applicant's claim that the new animal drug
application (NADA) for BRAVECTO (NADA 141-426) was submitted on April
8, 2014.
3. The date the application was approved: May 15, 2014. FDA has
verified the applicant's claim that NADA 141-426 was approved on May
15, 2014.
This determination of the regulatory review period establishes the
maximum potential length of a patent extension. However, the USPTO
applies several statutory limitations in its calculations of the actual
period for patent extension. In its application for patent extension,
this applicant seeks 792 days of patent term extension.

III. Petitions

Anyone with knowledge that any of the dates as published are
incorrect may submit either electronic or written comments and, under
21 CFR 60.24, ask for a redetermination (see DATES). Furthermore, as
specified in Sec. 60.30 (21 CFR 60.30), any interested person may
petition FDA for a determination regarding whether the applicant for
extension acted with due diligence during the regulatory review period.
To meet its burden, the petition must comply with all the requirements
of Sec. 60.30, including but not limited to: Must be timely (see
DATES), must be filed in accordance with Sec. 10.20, must contain
sufficient facts to merit an FDA investigation, and must certify that a
true and complete copy of the petition has been served upon the patent
applicant. (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.
Submit petitions electronically to https://www.regulations.gov at
Docket No. FDA-2013-S-0610. Submit written petitions (two copies are
required) to the Dockets Management Staff (HFA-305), Food and Drug
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
