Study Details
Study Description
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.

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.

Men who are not randomized to a treatment arm including favipiravir (or another arm identified as having teratogenic potential through semen) will no longer need to adhere to this after randomization.
-

-
Body weight ≥45 kg.
-
Access to reliable video conference, telephone, direct/text messaging, or other device permitting real-time, reliable information transfer.
Exclusion Criteria:
-
Pregnant or lactating women.
-
Known hypersensitivity or specific contraindications to the use of any of the active drugs in the treatment arms, or similar compounds.
-

-
respiratory rate >24 breaths/min
-
SpO2 <95% in room air.
-
Resting pulse rate ≥120 beats/min.
-
High likelihood of hospitalization in the opinion of the attending clinician.
-
QTcF >470 msec for females, or >450 msec for males, at screening.
-
Serum potassium <3.5 mmol/L at screening.

-
Currently receiving, or recently received (within 30 days prior to randomization) treatment with any antimalarial drugs.
-

-
Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of drugs, or which may jeopardize the safety of the volunteer or the objectives of the study. The Investigator should make this determination in consideration of the volunteer's medical history.
