Federal Register / Vol. 72, No. 60 / Thursday, March 29, 2007 / Notices
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 drug
products, the testing phase begins when
the exemption to permit the clinical
investigations of the human drug
product 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 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 VAPRISOL
(conivaptan hydrochloride). VAPRISOL
is indicated for treatment of euvolemic
hyponatremia in hospitalized patients.
Subsequent to this approval, the Patent
and Trademark Office received a patent
term restoration application for
VAPRISOL (U.S. Patent No. 5,723,606)
from Astellas Pharma, 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
5, 2006, FDA advised the Patent and
Trademark Office that this human drug
product had undergone a regulatory
review period and that the approval of
VAPRISOL 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
VAPRISOL is 2,796 days. Of this time,

2,096 days occurred during the testing
phase of the regulatory review period,
while 700 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 act) (21 U.S.C.
355(i)) became effective: May 6, 1998.
FDA has verified the applicant’s claim
that the date the Investigational New
Drug application became effective was
on May 6, 1998.
2. The date the application was
initially submitted with respect to the
human drug product under section
505(b) of the act: January 30, 2004. FDA
has verified the applicant’s claim that
the new drug application (NDA) for
VAPRISOL (NDA 21–697) was initially
submitted on January 30, 2004.
3. The date the application was
approved: December 29, 2005. FDA has
verified the applicant’s claim that NDA
21–697 was approved on December 29,
2005.
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 1,745 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) written or
electronic comments and ask for a
redetermination by May 29, 2007.
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 25, 2007. 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.
Comments and petitions should be
submitted to the Division of Dockets
Management. Three copies of any
mailed information are to be submitted,
except that individuals may submit one
copy. Comments are to be identified
with the docket number found in
brackets in the heading of this
document. Comments and petitions may
be seen in the Division of Dockets
Management between 9 a.m. and 4 p.m.,
Monday through Friday.

SUPPLEMENTARY INFORMATION:
I. Background
The Animal Feed Safety System
(AFSS) is FDA’s program for animal
feed aimed at protecting human and
animal health by ensuring animal feed
is safe. It covers the entire spectrum of
agency activities from preapproval of
food additives and drugs for use in feed,
to establishing limits for feed
contaminants, providing education and
training, conducting inspections, and
taking enforcement actions for ensuring
compliance with agency regulations.
The AFSS includes oversight of all feed
ingredients and mixed feed at all stages
of manufacture, production, distribution
and use, whether at commercial or noncommercial establishments.
During the past several years, FDA
has been considering changes that need
to be made to the AFSS to ensure that
it is comprehensive, preventive and
VerDate Aug<31>2005

Jkt 211001
risk-based. As part of this effort, the
agency is developing a model for
ranking the relative risks to human and
animal health from contaminants in
animal feed. An effective model will
permit the agency to systematically
distinguish among feed hazards based
on the relative risks they pose to
animals or humans. Such a model will
consider the risks of hazards present in
incoming materials or feed ingredients
and will also consider how activities at
feed manufacturing, storage,
distribution, and transportation
facilities may modify such risks. For the
purpose of the AFSS, FDA defines a
feed hazard as a biological, chemical, or
physical agent in, or condition of, feed
with the potential to cause an adverse
health effect in animals or humans.
Previously, FDA held three public
meetings to discuss the AFSS. The first
two meetings were held on September
23 and 24, 2003, in Herndon, VA and
on April 5 and 6, 2005, in Omaha, NE.
These public meetings included active
participation by consumers, animal feed
processors, animal producers, and State
and other Federal government agencies.
Following the meetings, we placed a
number of documents in FDA’s docket
for the AFSS project (see docket number
found in brackets in the heading of this
document). These documents included
transcripts of the meetings, summaries
of break-out discussion groups,
presentations of invited speakers and
meeting summaries. We also placed in
FDA’s docket a number of other
documents relating to the AFSS,
including a framework for the AFSS that
lists the principal components of the
AFSS and the gaps the agency has
identified which are being addressed by
the agency team working on the AFSS
project. These documents provided
general background material on the
AFSS for the third public meeting that
was held on September 12, 2006, in
Rockville, MD.
The September 2006 meeting was the
first of several planned by FDA to
discuss aspects of the AFSS relative risk
ranking model during the model’s
development by the agency. In this
model, information about the health
consequences posed by the hazardous
contaminants will be combined with
information about exposures to the
contaminants in animal feed. At the
September 2006 meeting, the agency
presented its current thinking on the
development of a health consequences
scoring system to represent the animal
and human health consequences
associated with the feed contaminants.
The meeting also afforded the
opportunity for attendees and agency
presenters to have an open discussion
PO 00000
Frm 00055
Fmt 4703
Sfmt 4703

concerning the health consequences
approach being considered by the
agency. The presentations and the
transcript of the meeting have been
added to the AFSS docket.
At the May 22, 2007, meeting, which
will be held in Gaithersburg, MD, FDA
will continue its discussions on the
development of the AFSS relative risk
ranking model by focusing on the
exposure component of the model. The
exposure scoring system under
development intends to address the
presence of contaminants in source
materials for feed ingredients and those
factors in manufacturing and/or
processing that may affect the levels of
contaminants in final feed formulations.
At the May 2007 meeting, the agency
will use the production of swine feed as
an example exposure scenario to
illustrate its approach to exposure
assessment.
At one or more subsequent meetings,
the agency will present information
about how health consequences and
exposure are combined to determine the
relative risks of contaminants in animal
feed and various aspects of the relative
risk model developed by the agency.
II. Meeting
We are holding the public meeting in
an effort to gather further information
from you, our stakeholders, on changes
to the AFSS that will help minimize
risks to animal and human health
associated with animal feed. Prior to the
public meeting, FDA will place a
document entitled ‘‘Exposure Scoring
for Feed Contaminants—A Swine Feed
Example’’ in the docket found in
brackets in the heading of this notice.
The document will summarize the
agency’s methods for determining
exposures to physical, chemical, and
microbiological contaminants that may
be present in swine feed. Details of
these methods will be discussed at the
meeting. A draft agenda for the meeting
will also be placed in the docket prior
to the meeting.
