I. Background

FDA is announcing the availability of a draft document entitled “Guidance for Reviewers: Potency Limits for Standardized Dust Mite and Grass Allergen Vaccines: A Revised Protocol” dated January, 2000.

Issues addressed in the guidance document, include but are not limited to, the following: (1) Diagnostic Equivalence, (2) therapeutic 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.

This draft guidance document represents the agency's current thinking with regard to the potency limits for standardized dust mite and grass allergen vaccines.

The document is intended to provide information and does not set forth requirements.
