Rubraquercus,
Yup, DSMB could arguably intervene. But my feeling here is that:
1) The trial is very short
2) The drug is safe (need less monitoring regarding safety, if at all).
3) This is a P2 trial with 75 patients only and the objective is to demonstrate benefit, therefore would be good to let it finalize un-tampered.
Actually, I think un-blinding the data before full enrollment is a mistake. We can wait a couple of weeks to give us good-powered results.
The question in my mind is what will happen when the resultant p-value is shown to be very low.
Will the FDA request a P3 trial with 100's of patients ??
Will the FDA say: in light of the urgency and extraordinary proof of benefit this is good enough. We will approve for use with "P4" follow up?
This is the question ...
