Funny that you would have that question. I just looked in to ask the same question because of the line ..........."The DSMB reviewed available study data and noted that no safety or efficacy concerns were identified". When the DSMB says there are no efficacy concerns does that mean the drug is working to one degree or another? To me, as a lay person, that is what that statement, wrt efficacy, says. I wonder what that statement means??
