It seemed to me that the poster wanted to know if the recruit was told which treatment they would receive Brilacidin or placebo), not whether they were told that they would receive one or the other....they obviously would learn that when they applied to enter the trial.
But, they are told that they'll receive a placebo or B.
Expend a modicum of effort and read up on double-blind clinical trials and you will discover your error pretty readily. There's no gray area on the matter.
