建议:
1,首先确认新增生产场地的情况,是否是新工厂,比如是否有DUNS、FEI号,如无,需根据相应法规申请DUNS、FEI号;
2,其次根据PAS变更要求,开展产品的验证生产并进行稳定性考察,3个月数据提交FDA。
根据FDA要求,PAS的GDUFA目标日期取决于PAS是否需要检查。如果PAS不需要检查,目标日期是从提交之日起4或6个月;但如果PAS需要检查,则目标日期为自提交之日起8个月或10个月。
3、根据FDA的GDUFA目标,通常此类变更的审批周期为10个月,期间可能发出核查要求。
4、如FDA现场检查通过,预期2-3个月内回复EIR报告。
依据:
Guidance for Industry1 ANDA Submissions – Prior Approval Supplements Under GDUFA ANDA提交—GDUFA下的补充申请
思考:
目前受疫情影响,FDA检查时间不可控,需要考虑评估作为产品风险点。
1. 首先确定新增的生产场地的情况,该场地是否有相应的类型产品的FDA的现场检查历史,以及检查历史情况。
2. 如果该场地有过同类型的产品的良好的历史检查情况,这个变更可以归为CBE30. 应该并不会涉及到现场检查。
3. 如果该场地该类型的产品从未被FDA检查过,或者有不好的检查历史,那么这个变更会归为PAS。并且按照FDA的PAI检查指南,以下情况是会建议进行现场检查:
• Establishment is named for the first time
• First application filed by applicant
• New dosage form than previously approved at the product
• Substantially different or novel manufacturing process/design than previously
approved
• Concerns about firm’s quality systems
• Questions about the firm’s capability of manufacturing quality products
• Scale-up concerns
• Product specific concerns
• NME, NTI, first generic?
• Time since last inspection?
(源自October 2019 Pharmaceutical Quality Symposium D1S07 PPT)
因此如果是这种情况下的新增场地,大概率是需要进行批准前检查,那么标准审评时间就是10个月。
4. 根据PAI检查指南,在就接收到NDA/ANDA后的60天内,相关办公室就会启动对场地的评估,如果确实需要进行PAI检查,会安排时间进行检查,并在GDUFA II的目标时间前完成(也就是10个月)。
根据FDA 2004年4月发布的工业指南changes to an approved NDA or ANDA Section VI manufacturing site,
对普通制剂新增生产场地,有2种情况是属于PAS
1.A move to a different manufacturing site, except one used to manufacture or process a drug substance intermediate, when the new manufacturing site has never been inspected by FDA for the type of operation that is being moved or the move results in a restart at the new manufacturing site of a type of operation that has been discontinued for more than two years.
2.A move to a different manufacturing site, except one used to manufacture or process a drug substance intermediate, when the new manufacturing site does not have a satisfactory CGMP inspection for the type of operation being moved.
如果不是属于上述情况,可以归为CBE30
a. A move to a different manufacturing site for the manufacture or processing of any drug product, in-process material, or drug substance that is not otherwise provided for in this guidance.
