I'm not sure what happened to all those promised chloroquine double-blind trials. Lately I mostly read arguments from doctors on the front lines that they're liking the results of using chloroquine rather early in a case, though they're unsure whether it's helpful when delayed until symptoms are severe. Unfortunately, this may not mean much except that a patient sample consisting of people who aren't yet very sick are going to do pretty well for the most part no matter what treatment they get, because only a small minority of patients draw the black bean and get horrifically sick. You really need careful studies to tease out slight gains in the rate of patients who avoid getting much more ill depending on whether they receive a particular early treatment. This is how we get widespread stories that melatonin, vitamin C, zinc, etc., are working great, because lots of people took them and didn't die. Nevertheless, I'd still ask my doctor for immediate chloroquine and a Z-pack if I tested positive or showed symptoms, and would cheerfully take the treatment if he prescribed it, because it shows promise of helping and seems to have an awfully small downside.
Meanwhile, there's perhaps a little good news for the much smaller subset of patients who did draw the black bean and are now seriously ill:
Remdesivir appears to help quite a bit, though it's definitely no magic cure. Unfortunately the recent good-news study was conducted by Remdesivir's manufacturer, so we have to take it with a grain of salt.
