一般情况下,起始物料和中间体不会在药典中收录。如果检测中涉及到HPLC、GC方法,就应该进行全验证。递交过 ...
目前来看,美国DMF完整性审查确实不需要起始物料的验证这部分材料,至少在每年欧盟公布的top 10 缺陷,没有提到少了起始物料验证这部分内容。应该是不需要的。
欧盟GUIDELINE ON THE CHEMISTRY OF NEW ACTIVE SUBSTANCES:This guideline replaces Note for Guidance on Chemistry of New Active Substance CPMP/QWP/130/96. It has been revised to change the location of the definition of active substance starting material from S.2.2 to S.2.3, as agreed in ICH CTD-Q-IWG.
Starting materials should be fully characterized to ascertain suitability for intended use
and complete specifications should be provided, including an impurities profile. The
possibility that impurities present in a starting material may be carried through the
synthesis/process unchanged or as derivatives should be discussed and should therefore,
if relevant, be controlled in the starting material by appropriate acceptance criteria with
suitably validated methods.
主要是这部分怎么把控的问题,看起来至少一个技术要求,不是申报材料必须、 |
