MAPP on Alternative Compendia Standards
The CDER Office of Pharmaceutical Quality has issued a Manual of Policies and Procedures (MAPP), Acceptability of Standards from Alternative Compendia (BP/EP/JP), to clarify for reviewers the appropriate use of quality standards for excipients, drug substances, and drug products found in the British, European, and Japanese pharmacopeias. The standards are used during chemistry, manufacturing, and controls review of INDs and NDAs, the document says.
The MAPP is not intended to establish the three foreign compendia as official compendia in place of or in addition to the United States Pharmacopeia/National Formulary. And it is not intended to preclude any current efforts to establish a process for evaluation and regulatory acceptance of harmonized analytical procedures and/or acceptance criteria.
According to the MAPP, it “is reasonable to accept an applicant’s proposal to use a quality standard” from one of the three named foreign compendia as part of the application for an excipient, drug substance, or drug product in the drug application if the foreign compendium’s standard is equivalent to or better than the corresponding standard in the U.S. compendium. It says that equivalent standards have the same acceptance criteria and make use of analytical procedures based on similar principles. A standard can be considered better that a corresponding standard for several reasons, it says, including narrower ranges for acceptance criteria or superior performance of the analytical procedure.
