# SUMMARY:

The Food and Drug Administration (FDA) is announcing the availability of a draft guidance for industry entitled “ANDAs: Impurities in Drug Products; Chemistry, Manufacturing, and Controls Information.” This draft guidance provides recommendations on what chemistry, manufacturing, and controls information sponsors should include regarding reporting, identification, qualification, and setting acceptance criteria for impurities that are classified as degradation products in drug products when submitting an abbreviated new drug application (ANDA) or supplement to support changes in drug substance synthesis or process, formulation of the drug product, the manufacturing process, or components of the container/closure system.

# DATES:

Submit written or electronic comments on the draft guidance by November 28, 2005. 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                        Submit written requests for single copies of the draft guidance to the Division of Drug Information (HFD-240), Center for Drug Evaluation and Research, Food and Drug Administration, 5600 Fishers Lane, Rockville, MD 20857.

# SUPPLEMENTARY INFORMATION:

## I. Background

                    In the                     **Federal Register**                     of January 5, 1999 (64 FR 516), FDA published the draft guidance for industry on “ANDAs: Impurities in Drug Products.” The draft guidance provided recommendations for including information in ANDAs and ANDA supplements about the reporting, identification, qualification of, and setting acceptance criteria for degradation products in drug products that are manufactured from drug substances produced by chemical synthesis.                

FDA is announcing the availability of a revised draft guidance for industry entitled “ANDAs: Impurities in Drug Products,” which revises the January 5, 1999, draft guidance. The draft guidance is being revised to update information on listing of degradation products, setting acceptance criteria, and qualifying degradation products in conformance with our current thinking and the revision of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) guidance for industry on “Q3B(R) Impurities in New Drug Products,” published in November 2003. The draft guidance is also being revised to remove sections of the guidance containing recommendations that are no longer needed because they are addressed in the more recent Q3B(R).

This draft guidance contains information collection provisions that 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 collection of information in this draft guidance was approved under OMB Control No. 0910-0001.

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 these topics. 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

                    Interested persons may submit to the Division of Dockets Management (see                     **ADDRESSES**                    ) written or electronic comments regarding this document. Submit a single copy of electronic comments or two paper copies of any mailed comments, except that individuals may submit one paper copy. Comments are to be identified with the docket number found in brackets in the heading of this document. Received comments may be seen in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
