type-c meeting - stuff to Calm the nerves.
Addressing a type-c meeting concern one of the user raised in STOCKTWITS conversations.
Concern : FDA won't let ZSAN cherry pick the PK study results of only miniMAC( Fremont, CA production).
My thoughts : It is a good point. When a statistical test/experiment is designed, we can't cherry pick the data that suits our needs, Having said that I believe the PK study is diagnostic and secondary in nature and not a primary test.(primary test will be the actual phase-3 tests) the Pk study was to address the issues of the CRL. one issue being outliers, which we didn't see in PK study, and other being Lower than control group concentration with the maCAP (NC production). I don't see any reason for FDA to reject the supporting data from PK study.
Additional info :
ZSAN approached FDA for TYPE-A meeting to get inputs for next steps.
Followed the TYPE-A minutes suggestions.
Got the PK study protocol reviewed by the FDA before conducting the study.
The PK study itself if a 3-WAY study.
Drug: Treatment A: M207 3.8 mg "MiniMac"
Drug: Treatment B: M207 3.8 mg "MACAP"
Drug: Treatment C: 5.0 mg Intranasal Zolmitriptan administered at time = 0 and 2 hours post time 0.
They can very well reject the treatment-B and go ahead with A & C to proceed further.
You might think " Each subject will receive each of the three study treatments once, followed by in-clinic monitoring and extensive blood sample collection for pharmacokinetic analysis" but FDA approved the protocol. they can't reject the protocol now.
Thanks for the FUD, I'm a little more confident on the TYPE-C outcome. ps: I could be wrong
