9 CFR Part 114
[Docket No. 04-064-1]
Viruses, Serums, Toxins, and Analogous Products; Expiration Date
Required for Serials and Subserials and Determination of Expiration
Date of Product
AGENCY: Animal and Plant Health Inspection Service, USDA.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: We are proposing to amend the Virus-Serum-Toxin Act
regulations to require licensees and permittees to confirm the proposed
expiration dating period of products by potency testing serials on
multiple occasions throughout the proposed dating period, rather than
only at release and at the approximate expiration date as is currently
required. We would require that those stability test data be submitted
to the Animal and Plant Health Inspection Service for review and
filing, and that the approval date be specified in a filed Outline of
Production. In addition, after a product is licensed and its dating
period confirmed, the licensee or permittee would have to submit a plan
to monitor the stability of the product and the suitability of its
dating period; that plan would have to include regular testing of
serials for potency during and at the end of dating. The proposed
changes would help clarify the distinction between specifying an
expiration date for an individual serial of a product and establishing
the appropriate expiration dating period for the product. The effect of
these proposed changes would be to establish a single uniform standard
for determining expiration dates for veterinary biological products.

SUPPLEMENTARY INFORMATION:
Background
The Virus-Serum-Toxin Act regulations in 9 CFR part 114,
``Production Requirements for Biological Products'' (referred to below
as the regulations), include requirements applicable to designating the
expiration date of a serial or subserial of veterinary biologics and
determining the expiration dating period (stability) for veterinary
biologics. Currently, Sec. 114.12 of the regulations requires each
serial or subserial of veterinary biological product prepared in a
licensed establishment to be given an expiration date determined in
accordance with the requirements prescribed in Sec. 114.13 of the
regulations. The regulations in Sec. 114.13 require the expiration
date described under Sec. 114.12 to be computed from the date of the
initiation of the potency test.
The expiration date of a product designates the end of the period
during which a biological product, when properly stored and handled,
can be expected, with reasonable certainty, to be efficacious. Thus,
the most precise determination of the expiration date occurs when the
product is tested at the end of its predicted shelf life. However, the
typical product may be released for distribution and sale before its
dating period is confirmed, which necessitates a mechanism for
predicting the product's shelf life. Prior to licensure, the stability
of each fraction of a product must be determined by methods acceptable
to Animal and Plant Health Inspection Service (APHIS). Typically, such
methods involve subjecting the product to extreme temperatures and
measuring its relative strength by conducting a potency test. Products
that pass the potency test are licensed with the provision that such
expiration dates must be confirmed by real-time testing as follows: For
products consisting of viable organisms each (prelicensing) serial
shall be tested for potency at release and at the approximate
expiration date until a statistically valid stability record has been
established; for nonviable biological products, each (prelicensing)
serial presented in support of licensure shall be tested for potency at
release and at or after the dating requested.
We are proposing to amend the title of Sec. 114.12 to read:
``Expiration date required for a serial.'' In addition, we propose to
amend this section by adding the wording ``computed from the date of
the initiation of the potency test'' and remove it from Sec. 114.13
where it is currently found. This change is intended to clarify the
fact that the expiration date of a serial, and not the dating period of
a product, is computed from the date of the initiation of the potency
test.
We are proposing to amend the title of Sec. 114.13 to read: ``
Determination of the expiration dating period of a product.'' This
change will show that it deals with a product's dating period rather
than the expiration date of a serial. The proposed revision of this
section would define a single uniform standard for determining the
dating period for all veterinary biologics; require the expiration
dating periods of a product to be confirmed by testing serials or
subserials on multiple occasions throughout their dating period in
place of the current requirement which only requires testing at the
beginning and end of the dating period in order to confirm stability;
require a report of the expiration dating period testing to be
submitted to APHIS for review and filing and the date of approval to be
specified in section VI of the filed Outline of Production; and after
the dating period has been approved, require that the stability of the
product and the suitability of the dating period be monitored by
regularly testing serials during and after their dating period.
APHIS is proposing these amendments because it has been shown that
the potency of most veterinary biologics degrades in a nonlinear
fashion, which could result in their potency reaching its lowest point
during the middle of the dating period rather than at the end. Testing
on only two occasions would be reasonable only if potency loss has a
strictly linear pattern, and this is usually not the case. Thus, APHIS
is proposing to evaluate a product's stability as a function of time by
requiring serials to be tested on multiple occasions when confirming
the dating period, and thereafter by monitoring stability on a regular
basis.
The proposed amendment would update and standardize testing to
establish/confirm the stability of veterinary biologics and improve the
reliability of expiration dating periods currently specified on the
labeling of veterinary biologics, thereby providing greater assurance
that the product, when properly stored and handled, will be
efficacious. We are therefore proposing to amend Sec. Sec. 114.12 and
114.13 as set forth below.
Executive Order 12866 and Regulatory Flexibility Act
This proposed rule has been reviewed under Executive Order 12866.
The rule has been determined to be not significant for the purposes of
Executive Order 12866 and, therefore, has not been reviewed by the
Office of Management and Budget.
This proposed rule would amend the Virus-Serum-Toxin Act
regulations in Sec. Sec. 114.12 and 114.13 concerning expiration dates
and the determination of the stability of veterinary biologics to:
Change the title of the sections; require veterinary biologics
licensees and permittees to evaluate the stability of veterinary
biologics as a function of time by testing serials for potency
throughout and after their proposed dating period beginning at the date
of final formulation; require that the expiration dating period be
determined by testing serials for potency on multiple occasions
throughout and after the proposed dating period; require that a report
of the results of the testing to confirm expiration dating be submitted
to APHIS for review and filing and that the date of approval be
specified in the filed Outline of Production; and require monitoring of
the stability of the product and the suitability of the dating period.
The overall effect of these proposed amendments would be to establish a
single uniform standard for confirming the expiration dating period of
veterinary biologics.
This proposed rule would affect all licensed manufacturers of
veterinary biologics. Currently, there are approximately 152 veterinary
biologics manufacturers, including permittees. According to the
standards of the Small Business Administration, most veterinary
biologics establishments are small entities. We believe that this
proposed rule would not have a significant effect on small entities
because all veterinary biologics manufacturers are currently required
to confirm the expiration dating of the products that they produce and
to submit a report to APHIS for review and filing. In addition, the
proposed requirements to test serials on multiple occasions when
confirming expiration dating and to require post-licensing stability
monitoring are not expected to have a significant effect, as most
veterinary biologics manufacturers routinely test and monitor the
stability of products throughout their dating period.
Under these circumstances, the Administrator of the Animal and
Plant Health Inspection Service has determined that this action would
not
[[Page 21987]]
have a significant economic impact on a substantial number of small
entities.
Executive Order 12372
This program/activity is listed in the category of Federal Domestic
Assistance under No. 10.025 and is subject to Executive Order 12372,
which requires intergovernmental consultation with State and local
officials. (See 7 CFR part 3015, subpart V.)
Executive Order 12988
This proposed rule has been reviewed under Executive Order 12988,
Civil Justice Reform. It is not intended to have retroactive effect.
This rule would not preempt any State or local laws, regulations, or
policies unless they present an irreconcilable conflict with this rule.
The Virus-Serum-Toxin Act does not provide administrative procedures
which must be exhausted prior to a judicial challenge to the provisions
of this rule.
Paperwork Reduction Act
This proposed rule contains no new information collection or
recordkeeping requirements under the Paperwork Reduction Act of 1995
(44 U.S.C. 3501 et seq.).
List of Subjects in 9 CFR Part 114
Animal biologics, Reporting and recordkeeping requirements.
Accordingly, we propose to amend 9 CFR part 114 as follows:
PART 114--PRODUCTION REQUIREMENTS FOR BIOLOGICAL PRODUCTS
1. The authority citation for part 114 would continue to read as
follows:
Authority: 21 U.S.C. 151-159; 7 CFR 2.22, 2.80, and 371.4.
2. Section 114.12 would be revised to read as follows:
Sec. 114.12 Expiration date required for a serial.
Unless otherwise provided for in a Standard Requirement or filed
Outline of Production, each serial or subserial of biological product
prepared in a licensed establishment must be given an expiration date
computed from the date of the initiation of the first potency test. A
licensed biological product shall be considered worthless under the
Virus-Serum-Toxin Act subsequent to the expiration date appearing on
the label.
3. Section 114.13 would be revised to read as follows:
Sec. 114.13 Determination of the expiration dating period of a
product.
(a) An expiration dating period shall be assigned to each product.
When tested at any time during the dating period, the potency of the
product must not be less than the minimum specified in the filed
Outline of Production.
(b) Prior to licensure, a proposed expiration dating period for the
product should be determined by assessing the stability of each of its
fractions by methods acceptable to Animal and Plant Health Inspection
Service. The proposed dating period must be confirmed by testing the
serials for potency on multiple occasions throughout the proposed
dating period beginning at the date of final formulation specified in
the filed Outline of Production. A report of the study should be
submitted to Animal and Plant Health Inspection Service for review and
filing and the date of approval should be specified in section VI of
the filed Outline of Production.
(c) After the product is licensed and its dating period confirmed,
the licensee or permittee must submit a plan to monitor the stability
of the product and the suitability of its dating period that includes
regularly testing serials for potency during and at the end of dating.
(d) Subsequent changes in the dating period for a product may be
granted, based on the submission of a study to support a revision of
the Outline of Production.
Done in Washington, DC, this 22nd day of April 2005.
