AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is announcing the 
availability of a guidance document entitled ``Guidance for Reviewers: 
Potency Limits for Standardized Dust Mite and Grass Allergen Vaccines: 
A Revised Protocol'' dated October 2000. The guidance document provides 
information on the revised release limits to be used by the Center for 
Biologics Evaluation and Research (CBER) for its evaluation of 
standardized dust mite and grass allergen vaccines submitted to CBER 
for lot release. The establishment of suitable potency limits for 
standardized allergen vaccines submitted to CBER for lot release is 
necessary to help ensure the safety, purity, and potency of these 
products. The guidance document announced in this notice finalizes the 
draft guidance entitled ``Guidance for Reviewers: Potency Limits for 
Standardized Dust Mite and Grass Allergen Vaccines: A Revised 
Protocol'' that was announced in the Federal Register on February 15, 
2000.

DATES: Submit written comments at any time.

ADDRESSES: Submit written requests for single copies of ``Guidance for 
Reviewers: Potency Limits for Standardized Dust Mite and Grass Allergen 
Vaccines: A Revised Protocol'' dated November 2000 to the Office of

I. Background

    FDA is announcing the availability of a guidance document entitled 
``Guidance for Reviewers: Potency Limits for Standardized Dust Mite and 
Grass Allergen Vaccines: A Revised Protocol'' November July 2000. The 
guidance document provides information to FDA reviewers regarding 
broader relative potency limits for CBER evaluation of standardized 
dust mite and grass allergen vaccines submitted to CBER for lot 
release. Issues addressed in the guidance document include, but are not 
limited to, the following: (1) Diagnostic equivalence, (2) theraputic 
equivalence, (3) safety equivalence, (4) lot-to-lot variation in 
allergen vaccine potency, and (5) current and broadened CBER release 
limits for standardized dust mite and grass allergen vaccines submitted 
to CBER for lot release. The guidance document announced in this notice 
finalizes the draft guidance entitled, ``Guidance for Reviewers: 
Potency Limits for Standardized Dust Mite and Grass Allergen Vaccines: 
A Revised Protocol'' that was announced in the Federal Register on 
February 15, 2000 (65 FR 7557).
    This guidance document represents the agency's current thinking 
with regard to the potency limits for standardized dust mite and grass 
allergen vaccines. It does not create or confer any rights for or on 
any person and does not operate to bind FDA or the public. An 
alternative approach may be used if such approach satisfies the 
requirements of the applicable statutes and regulations. As with other 
guidance documents, FDA does not intend this document to be all-
inclusive and cautions that not all information may be applicable to 
all situations. The document is intended to provide information and 
does not set forth requirements.

II. Comments

    Interested persons may submit to the Dockets Management Branch 
(address above) written comments regarding this guidance document. Two 
copies of any comments are to be submitted, except individuals may 
submit one copy. Comments should be identified with the docket number 
found in the brackets in the heading of this document. A copy of the 
document and received comments are available for public examination in
