A Randomized Trial of Ivermectin-Doxycycline and Hydroxychloroquine-Azithromycin therapy on COVID19 patients
Small 116 patient RCT comparing ivermectin+doxycycline and HCQ+AZ, not showing a significant difference in time to PCR negative or symptom resolution. Time to symptomatic recovery was 5.93 days for ivermectin+doxycycline vs. 6.99 days for HCQ+AZ. Given the long half-life of HCQ and the lack of a loading dose, it may take several days for HCQ to reach therapeutic levels. 10% of HCQ+AZ patients were lost to followup (2x ivermectin+doxycycline). There is no comparison with a control group.
