美国FDA的“Post-approval Changes to Drug Substances”这份指南里规定“Where drug substance information is provided in a DMF, a letter(s) of authorization must be provided to allow the applicant to reference the DMF. Any addition, change, or deletion of information in the master file must be submitted to the master file in the form of an amendment. Further, the master file holder must notify each person authorized to reference the DMF of the nature of the changes, and should provide as much detail as is consistent with the confidentiality agreement between the master file holder and the authorized person, so that the authorized person can determine how to report the changes in the approved application. In turn, application holders must notify FDA of each change in each condition established in an approved application, excluding the variations already provided for in the application. |
