I think CI has a legit point. The study will have three phases: Screening Period, Treatment Period, and Follow-Up Period. So the study period itself seems to be more than 28 days. Outcomes measures are not reported to Cytodyn, SAE's are. SAE's are reported during the study as they occur for safety monitoring purposes. So any SAE that occurs during the study would be reported to Cytodyn and it seems that NP so far has received 87 reports of SAE that resulted in deaths.
That's just my understanding of the trial process, not an expert by any means.
