  • 1.  Retest Date Extension Notification for API

    Posted 18-Mar-2014 17:08
    What type of notification is required For an API Retest Extension: 
        Is it required to have a CBE-30 prior to implementation
            OR
        Does this fall under the usual minor category for notification to the FDA?

    Thank you in advance for all your insights and time.

    Kelsey,

    Your question is timely, please reference the Guidance for Industry CMC Postapproval Manufacturing Changes to be documented in Annual Reports, Section 7 Miscellaneous Changes 7.1 Page 11, "Extension of the drug substance retest dating period or drug product expiration dating period based on REAL-TIME stability data from pilot-scale or larger/commercial-scale batches following an APPROVED stability protocol. The Guidance was issued March 2014. 

    Note the caveats, REAL-TIME stability data and APPROVED stability protocol. Hopefully your API plan included an extension of the retest dating period in a stability protocol such that you can use the annual reporting process, if not I would have a discussion with your division on the appropriate pathway to have a new stability protocol reviewed and the mechanism to submit the new data and revise the retest expiry. 

    Regards,

    Dar

    Dear Kelsey:

    I agree with Dar's recommendation and as she noted, ensure you meet the caveats. Good luck.
