In the Anavex 2b/3 Alzheimer's trial, were placebo patients typically allowed to continue taking their standard of care medication? I think I recall that in previous Anavex AD trials, placebo patients continued to take Donepezil(?). In the remdesivir clinical trial placebo patients received the stand of care and the odds ratio was used to compare remdesivir patients with standard of care placebo patients. Of course, that was the plan in remdesivir from the start of the trial and the trial participants numbered over 1,000. Therefore, the remdesivir trial may not be a valid comparison.
