ANDA新增生产场地的补充申请的PAS变更需要多久
QA注册申报

目前已经获批的产品已拿到ANDA,计划新增加另一个工厂进行代工生产,涉及生产场地的变化;

想了解下这类PAS变更在递交FDA的时候具体是如何操作的流程,每个环节预期需要多少时间,涉及现场检查的最快时间是多久?


想请社区的大神指点下!!感谢!!

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

FDA药品设施登记使用邓白氏码

FEI

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)。

您的意思是,场地新增有可能不是PAS么?这一点似乎与采纳答案不符,是否可以补充一下?

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.
