关于无菌产品批次量调整与变更等级、验证的依据
QA

1. 产品投料量变更范围与变更等级的关系是否有依据?产品投料量变更范围与是否需要进行工艺验证是否有依据?如我们现在规定投料量在20%以内调整属于微小变更,不需要进行工艺验证(不区分合成产品和无菌产品);CEP指南中规定,除无菌产品外的批次量变更,10倍或1/10以内的属于微小变更,是否有其他依据?

2. 无菌产品投料量变更,法规允许多大范围是不需要经过预先批准的?是否有依据?

谢谢!

FDA Guidance for Industry Changes to an Approved NDA or ANDA

该指南第7

Major Changes (prior Approval Supplement)

Changes that may affect drug product sterility assurance including, where appropriate, process changes for sterile drug substances and sterile packaging components.

Changes to aseptic processing methods, including scale, that extend the total processing, including bulk storage time, by more than 50 percent beyond the validated limits in the approved application.
