True, or people can see that since there are 4 arms to the trial, that A alone gives outcome X, A+R gives X, R alone gives 0, and 0 alone gives 0. Therefore R=0, as you noted so nicely.

In other words, this trial will show that adding remdesivir gives no benefit to aviptadil alone, and remdesivir alone is worthless in late stage Covid.

Lenzilumab, aviptadil, barcitinib and other drugs all now have/had government funding with them running large trials as part of ACTIV/ACTT. Why shouldn't CYDY/LL get in on the free trial game too?

Fauci is convinced that Covid treatment should pair an antiviral with an immunomodulator, and R is the only/best antiviral they have (molnupavir, neutralizing antibodies, and a few other drugs are also antiviral), so that's why they are testing A with R.
