各位好,在看FDA在04/24/2023-05/09/2023检查无锡药明生物后,发给药明的483中,有一条缺陷项是关于DS条件放行后用于DP生产的。我们的产品目前在临床阶段,因为配合临床的进度,DS均为在条件放行后即用于DP生产,最终DP放行前完成DS的完全放行,然后DP再完成最终放行。大家怎么理解这一条缺陷呢?有没有相关法规对这个问题作出规定呢?
1. The Quality Unit oversight is deficient. Specifically,
a. Not all (b)(4) drug substance (DS) batches are withheld from use until the lots have been fully released by the Quality Unit. Specifically, multiple (b)(4) DS batches have been partially released and manufactured into drug product (DP) batches prior to obtaining unprocessed bulk (UPB) sample results and all DS release testing results, and completing all document and data reviews by the Quality Unit.
