[Docket No. 92D-0039]
Animal Drug Manufacturing; Revised Guideline; Availability
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is announcing the
availability of the revised four-part guideline entitled, ``Animal Drug
Manufacturing Guidelines, 1994'' prepared by the Center for Veterinary
Medicine (CVM). These guidelines describe the data and information for
the manufacturing portions of abbreviated new animal drug applications,
new animal drug applications, and supplements for pharmaceutical dosage
forms.
DATES: Written comments on these guidelines may be submitted at any
time.
ADDRESSES: Submit written requests for single copies of the revised
guidelines entitled, ``Animal Drug Manufacturing Guidelines, 1994: I.
Pilot Batch Manufacture, II. Tentative Expiration Dates, III.
Manufacturing Sites, and IV. New Animal Drug Substance Sources'' to the
Communications and Education Branch (HFV-12), Center for Veterinary
Medicine, Food and Drug Administration, 7500 Standish Pl., Rockville,
MD 20855, 301-594-1755. Send two self-addressed adhesive labels to
assist that office in processing your requests. Submit written comments
on the revised guidelines to the Dockets Management Branch (HFA-305),
Food and Drug Administration, rm. 1-23, 12420 Parklawn Dr., Rockville,
MD 20857. Requests and comments should be identified with the docket
number found in brackets in the heading of this document. A copy of the
revised guidelines and received comments may be seen at the Dockets
Management Branch between 9 a.m. and 4 p.m., Monday through Friday.
FOR FURTHER INFORMATION CONTACT: William G. Marnane, Center for
Veterinary Medicine (HFV-143), Food and Drug Administration, 7500
Standish Pl., Rockville, MD 20855, 301-594-0678.
SUPPLEMENTARY INFORMATION: The Food and Drug Administration (FDA) is
announcing the availability of the revised four-part guideline
entitled, ``Animal Drug Manufacturing Guidelines, 1994: I. Pilot Batch
Manufacture, II. Tentative Expiration Dates, III. Manufacturing Sites,
and IV. New Animal Drug Substance Sources'' prepared by CVM. These
guidelines are intended to be used by both pioneer and generic
manufacturers of veterinary drug products so that they are informed of
the type of information that FDA believes will provide an acceptable
submission to support the manufacturing requirements for new animal
drug applications, abbreviated new animal drug applications, and
supplemental applications for pharmaceutical dosage forms. In the
Federal Register of August 21, 1992 (57 FR 37979), FDA issued a notice
of availability of the four CVM guidelines entitled, ``Animal Drug
Manufacturing Guidelines, 1992.'' Comments by the public were requested
to be submitted at any time so that future revisions of the guidelines
could be developed in consideration of the remarks.
The agency received three comments on the 1992 guidelines. The
comments came from two drug manufacturers and one trade association.
The 1992 guidelines have been revised as a result of these comments and
from internal discussions within CVM.
Many editorial comments were made about all four guidelines. The
editorial comments were adopted in the revised guidelines when the
agency deemed that they were appropriate and provided clarification.
Technical comments about ``Guideline I. Pilot Batch Manufacture''
focused on the CVM recommendations for the size of the test batch and
the type of equipment or production facility that is appropriate for
manufacturing test lots. A suggestion was made to allow bridging data
in cases where the recommendations for batch size, production facility,
equipment, and standard operating procedures are not practicable.
Technical comments about ``Guideline II. Tentative Expiration Dates''
centered on a clarification of the definition of exaggerated storage
conditions for different dosage forms and the application of expiration
dating to all manufacturing sites for one drug product. Technical
comments about ``Guideline III. Manufacturing Sites'' included
criticisms of the definitions of the different types of manufacturing
sites, the option for the agency to request bioequivalence data, and
the appropriate location of sterile process validation data in the drug
application. Technical comments about ``Guideline IV. New Animal Drug
Substance Sources'' were made regarding the definitions of primary and
alternate sources of the new animal drug substance, test batch and
stability data for supplemental applications, and bioequivalence data
requirements for mastitis products. All of these comments were
considered in the revision of the manufacturing guidelines.
One of the most significant changes to the 1992 guidelines is to
allow bridging data to be submitted when the recommendations for batch
size, production facility, equipment, and standard operating procedures
for pilot [[Page 13161]] batches are not practicable. The sponsor may
create an alternative plan to that recommended in order to compare the
bioavailability and stability characteristics of the test and
production batch. Another major change to the guidelines is the
provision of an alternate means by which sponsors may meet the
supplemental application recommendations for alternate manufacturing
sites and alternate sources of bulk drug substance when multiple NADA's
and ANADA's are affected. The sponsor may request that pilot batches of
representative drug products within the same dosage form class be
manufactured instead of producing pilot batches of all affected drug
products.
These ``Animal Drug Manufacturing Guidelines, 1994'' are not
intended to be individual stand-alone documents. Much of the
information presented in one guideline may be equally important to the
correct interpretation of the other guidelines. Therefore, all four
guidelines are being issued concurrently.
Guidelines state procedures or practices that may be useful to the
persons to whom they are directed, but are not legal requirements. The
agency is in the process of revising Secs. 10.85(d) and 10.90(b) (21
CFR 10.85(d) and 10.90(b)). Therefore, these guidelines are not being
issued under authority of present Secs. 10.85(d) and 10.90(b). A person
may follow the guideline or may choose to follow alternate procedures
or practices. If a person chooses to use alternate procedures or
practices, that person may wish to discuss the matter further with the
agency to prevent an expenditure of money and effort on activities that
may later be determined to be unacceptable to FDA. A guideline does not
bind the agency, and it does not create or confer any rights,
privileges, or benefits for or on any person. When a guideline states a
requirement imposed by statute or regulation, however, the requirement
is law and its force and effect are not changed in any way by virtue of
its inclusion in the guideline.
Interested persons may, at any time, submit to the Dockets
Management Branch (address above) written comments on the guideline.
Two copies of any comments 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. The guideline
and received comments are available for public examination in the
Dockets Management Branch between 9 a.m. and 4 p.m., Monday through
Friday.
Received comments will be considered to determine if further
revision of the guideline is necessary.
Dated: March 6, 1995.

Deputy Commissioner for Policy.
