AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice.

SUMMARY:

The Food and Drug Administration (FDA) is announcing the availability of a draft guidance for industry entitled “Assay Development for Immunogenicity Testing of Therapeutic Proteins.” The draft guidance provides recommendations to facilitate industry's development of immune assays for assessment of the immunogenicity of therapeutic proteins during clinical trials.

DATES:

Submit written or electronic comments on the draft guidance by February 2, 2010. General comments on agency guidance documents are welcome at any time.

ADDRESSES:

Submit written requests for single copies of the draft guidance to the Division of Drug Information, Center for Drug Evaluation and Research, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 51, rm. 2201, Silver Spring, MD 20993-0002; Office of Communication, Outreach, and Development (HFM-40), Center for Biologics Evaluation and Research, Food and Drug Administration, 1401 Rockville Pike, Rockville, MD 20852-1448. Send one self-addressed adhesive label to assist that office in processing your requests. Submit written comments on the draft guidance to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852.

SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Assay Development for Immunogenicity Testing of Therapeutic Proteins.” This guidance was created by a working group that consisted of staff from the Center for Drug Evaluation and Research (CDER) and the Center for Biologics Evaluation and Research (CBER). Because clinicians rely on the observed immunogenicity rates listed in the “Immunogenicity” section of drug labeling, development of validated, sensitive immune assays is critical to patient care. This guidance discusses immunogenicity testing during drug product development and provides recommendations on assay development, clinical aspects of assay validation, assay validation, assay testing implementation, and other aspects of immunogenicity testing.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the agency's current thinking on the development of immune assays for assessment of the immunogenicity of therapeutic proteins during clinical trials. 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.

II. Comments
