A Proposed Rule by the Animal and Plant Health Inspection Service on 04/28/2005
Docket No. 04-064-1
List of Subjects in 9 CFR Part 114
https://www.federalregister.gov/d/05-8516 https://www.federalregister.gov/d/05-8516
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.

Please state that your comment refers to Docket No. 04-064-1.
Dr. Albert P. Morgan, Chief of Operational Support, Center for Veterinary Biologics, Licensing and Policy Start Printed Page 21986Development, VS, APHIS, 4700 River Road Unit 148, Riverdale, MD 20737-1231; (301) 734-8245.
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, § 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 § 114.13 of the regulations. The regulations in § 114.13 require the expiration date described under § 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 § 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 § 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 § 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 §§ 114.12 and 114.13 as set forth below.
This proposed rule would amend the Virus-Serum-Toxin Act regulations in §§ 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 Start Printed Page 21987have a significant economic impact on a substantial number of small entities.
Accordingly, we propose to amend 9 CFR part 114 as follows:
1. The authority citation for part 114 would continue to read as follows:
2. Section 114.12 would be revised to read as follows:
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:
(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.
