Interventions	Details of intervention Type and dose: ivermectin 0.2 mg/kg to 0.4 mg/kg, no details on frequency scheme Route of administration: oral Treatment details of control group Placebo, azithromycin, hydroxychloroquine are named in the protocol as comparatory, but unclear design of study arms Concomitant therapy: unclear
Outcomes	Primary study outcome Efficacy will be measured by comparing clinical cure, microbiology, need for hospital admission due to clinical or analytical, blood gas, radiological deterioration, or a combination of these for each arm. Relevant review outcomes planned To assess the clinical cure rate after 2 weeks of treatment To evaluate the microbiological cure rate 72 h after treatment To analyze adverse events to treatment Additional study outcomes To analyze the improvement in clinical parameters (symptoms and physical examination) To assess the failure rate and admission requirements for disease progression To analyze the factors of weak or poor response to ivermectin
