FDA is announcing the availability of a document entitled “Guidance for Industry: Potency Tests for Cellular and Gene Therapy Products” dated January 2011. The guidance document provides manufacturers of cellular and gene therapy 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 acceptance criteria for product release.
In the Federal Register of October 9, 2008 (73 FR 59635), FDA announced the availability of the draft guidance of the same title. FDA received several comments on the draft guidance and those comments were considered as the guidance was finalized. A summary of changes includes the addition of text related to adjuvant testing and modification of assay parameters for validation studies. In addition, editorial and formatting changes were made to improve clarity. The guidance announced in this notice finalizes the draft guidance dated October 2008.
The guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents 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 requirements of the applicable statutes and regulations.
