RegisterApproved Pilot and Failed Pivotal Study [Study Assessment]
Dear Lucas
As per my experience, this is a clear case of Scale-up gone bad (assuming that the Pilot was sone on Lab batch and Pivotal was done on Exhibit batches)
First attempt should be to do some proper in vitro studies to find out the differences between both the batches and then to take a call.
For better understanding could you confirm
a) BCS class of drug (impact of PSD)
b) type of formulation (IR /ER)
c) pH solubility and degradation profile
d) Variations in DT/dissolution observed for both the batches?
e) Any changes in pilot and pivotal study sites?
Regards
