To Evaluate the Safety and Efficacy of TQ Formula in Covid-19 Participants

This is a randomized (1:1), double-blind, placebo-controlled phase 2 study to assess safety and efficacy of Total TQ Formula (3 g daily dose of Nigella Sativa Oil) capsules versus placebo in treating patients who have tested positive for novel Coronavirus 2019 (Covid-19) in the outpatient setting.

Patients will be treated at a dose of 500 mg, 3 capsules, two times a day for 14 days from date of randomization. Quantitative viral load as measured by RT-PCR will be evaluated at baseline and on days 7 and 14. Covid-19 symptoms will be measured throughout the study using Modified FLU-PRO Plus.

Study Population: Up to 60 participants will be randomized 1:1 to receive either TQ Formula Capsules + Standard of Care (SOC) or placebo +SOC

Phase: Phase II

Approximately 2-4 centers in the United States
