I don't see how the SOC could work against Brilacidin in the trial. B attracts the virus and kills it, it should not attract the SOC IMO so the SOC becomes a sideline body, not an active body in the trial, at least in relation to Brilacidin molecules.
We know Rems.... didn't work against B in the in vitro investigation but seemed to have some synergy effect with it.
Expect the same for fav.... but that is only an opinion.
