it seems that some EU countries are now asking for a substantial amendment for shelf-life extension even if the IMPD includes under “P.8 Stability” the proposed text explaining the non-substantial shelf-life extension plan.
- List item
Could you please confirm if you experience the same?
See example of IMPD text that is added to not require notification of a substantial amendment as long as the following criteria are met:
- All stability data must meet applicable specifications (Section P.5.1) for tests in the
stability protocol for long-term storage conditions.
- An evaluation of long-term stability data show all test parameters remaining within
applicable specifications upon extension to a new shelf life.
- Stability data for GMP lots drug product are currently being generated at long-term storage conditions and at accelerated storage conditions. These clinical lots will continue to be monitored throughout the course of the clinical study.
- Dating extensions based on available real time data and acceptable accelerated data will
not exceed 12 months plus the available real time data.
Thanks in advance for your feedback.
Wish you All a great day !
