This final guidance is intended to assist original applicants and holders of approved new drug applications (NDAs), abbreviated new drug applications (ANDAs), and biologics license applications (BLAs) with implementing a chemistry, manufacturing, and controls (CMC) postapproval change through the use of a comparability protocol (CP). A CP is a comprehensive, prospectively written plan for assessing the effect of a proposed postapproval CMC change(s) on the identity, strength, quality, purity, and potency of a drug product, including a biological product (i.e., product), as these factors may relate to the safety or effectiveness of the product (i.e., product quality).
