Message: Re: Apabetalone......a Calculated Risk

Perhaps the 9 positive DSMB reports can increase the odds of success, as Paladin suggested. Also, if a trial passes pre-specified interim analyses, such as futility analysis or sample size re-estimation analysis, then this may be interpreted as a positive and possibly increase the odds of success. However, Resverlogix opted to not perform the pre-specified futility analysis at 50% of events or the sample size re-estimation analysis at 75% of events.

I agree that the 9 positive DSMB reports are a plus and suggest, in my opinion, at the very least that: 1) apabetalone is not eliciting any unanticipated adverse events construed to be drug related; and 2) apabetalone is not increasing the risk for MACE. Since the interim futility and sample size re-estimation analyses were not performed, there is still a chance, in my opinion, that BETonMACE continues while apabetalone has no appreciable benefit. However, that is not my favored view based upon all of the clinical and pre-clinical evidence. By the way, the DSMB is not blinded.
