Design outcomes

Primary

MeasureTime frame
The proportion of patients with mild/moderate COVID-19 whose clinical condition worsened measured using SpO2 < 90 % (severe clinical COVID-19) from baseline up to days 7 and 14 from randomization

Secondary

MeasureTime frame
1. SARS-CoV2 viral load measured using PCR on days 7 and 14 of randomisation 2. EKG tracing (prolongation of the QTc interval), results of creatinine, ALAT, ASAT, hemoglobin, WBC and Platelets measured using standard medical laboratory methods at baseline and on the 7th and 14th day

Countries

Congo, Democratic Republic
