SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft document entitled 
``Guidance for Industry: Potency Tests for Cellular and Gene Therapy 
Products'' dated October 2008. The draft guidance document provides 
manufacturers of CGT products with recommendations for developing tests 
to measure potency. The recommendations are intended to clarify the 
potency information needed to support an IND or a BLA. Because potency 
measurements are designed specifically for a particular product, the 
guidance does not make recommendations regarding specific types of 
potency assays, nor does it propose criteria for product release.
    The draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent FDA's current thinking on this topic. 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 requirement of the applicable statutes 
and regulations.

II. Paperwork Reduction Act of 1995

    The draft guidance refers to previously approved collections of 
information found in FDA regulations. These collections of information 
are subject to review by the Office of Management and Budget (OMB) 
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The 
collections of information in 21 CFR part 211 has been approved under 
0910-0139, expiration date September 20, 2008; the collections of 
information in 21 CFR part 312 has been approved under 0910-0014, 
expiration date May 31, 2009; the collections of information in 21 CFR 
part 601 has been approved under 0910-0338, expiration date June 30, 
2010.

III. Comments

    The draft guidance is being distributed for comment purposes only 
and is not intended for implementation
