Small early terminated very late stage (86% on oxygen, 44% enrolled in the ICU) RCT comparing HCQ vs. AZ, not finding a significant difference between the two treatments. There is no comparison with a control group. HCQ patients not in the ICU at enrollment (slightly earlier treatment) did better, OR 0.95 vs. 1.13.
HCQ dosage is relatively low:
Dose in first 24 hours - 1g (compare to Boulware et al. 2g)
Dose in 5 days - 2.4g (compare to Boulware et al. 3.8g)
