Brief Summary:
This exploratory study is a randomized, single center, open label study of four different experimental treatment arms versus standard of care for the treatment of SARS-CoV-2 infection in symptomatic outpatients with mild disease at the time of enrollment.

Condition or disease Intervention/treatment Phase
COVID-19 Other: Standard of care (Paracetamol) Drug: Artesunate-amodiaquine Drug: Pyronaridine-artesunate Drug: Favipiravir plus Nitazoxanide Drug: Sofosbuvir/daclatasvir Phase 2

Detailed Description:
This phase 2, exploratory study will be an adaptive, randomized, open label, trial for treatment of individuals in an outpatient settings with mild SARS-CoV-2 infection. The primary outcome is focused on the evaluation of efficacy of the proposed experimental drugs in reducing upper respiratory viral shedding, defined as viral clearance (i.e., negative swab) on Day 7. Key secondary outcomes focus on other measures of viral shedding, safety evaluation, progression to LRTI (defined by resting blood oxygen saturation level [SpO2] <93% sustained for two readings two hours apart and presence of subjective dyspnoea or cough), disease severity, clinical resolution rate, and cumulative incidence of hospitalization or mortality at Day 28.
