My problem is that there are too many inconclusive trial. Someone makes a small trial without a control group, so the result is promising but difficult to interpret. Someone else makes a small trial without a control group, so the result is promising but difficult to interpret. Another person makes a small test without a control group, so the result is promising but difficult to interpret. ...

So after a few months, we only have promising inconclusive results.

Not that all the trials are different, so it is difficult to compare them. IIRC There was a recent trial with remdesivir without good results, but they only tried the drug in patients with strong symptoms. So people asked what happens if they use the drug in the beginning of the infection.
