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).
