I haven't noticed many stating positive results related to Chloroquine, but one did come out this week.  I'm not in position to judge its quality:  https://www.medrxiv.org/content/10.1101/...20057539v1  "none of patients treated with chloroquine developed severe pneumonia, though without significance (difference, 12.0%; 95% CI, -3.5% to 30.0%) by propensity score matching."

That report also did indicate that those with hypertension using ACE Inhibitors & ARB therapies had better outcomes than thosse that used other drugs.
