Study of ZnAg Liquid Solution to Treat COVID-19 Symptomatic Participants

Covid19 Clinical Trial

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of the Efficacy and Safety of ZnAg Liquid Solution to Treat COVID-19 in Acutely Symptomatic Non-Hospitalized Participants

Status Completed

Clinical Trial Summary

This is a multi-site, randomized, double-blind, placebo-controlled study assessing the efficacy and safety of ZnAg liquid solution in symptomatic participants with acute COVID-19 that are not hospitalized at the time of enrollment.

Clinical Trial Description

This is a multi-site, randomized, double-blind, placebo-controlled study assessing the efficacy and safety of ZnAg liquid solution in symptomatic participants with acute COVID-19 (PCR documented SARS-CoV-2 infection) that are not hospitalized at the time of enrollment (e.g., present to an emergency room without being admitted to the hospital or diagnosed in an outpatient clinic setting). Participants must have presented with two or more symptoms of acute COVID-19 (within 96 hours prior to the Baseline visit) self-reported as moderate or severe at the Baseline visit, including fever, myalgia, fatigue, chest tightness, chills, cough, diarrhea, gastrointestinal distress, headache, sore throat, congestion or runny nose, ageusia, anosmia, nausea, tingling or numbness in the extremities, or shortness of breath. SARS-CoV-2 infection must be confirmed by polymerase chain reaction (PCR) testing within 96 hours prior to the Baseline visit. Participants who meet all inclusion criteria and none of the exclusion criteria and who formally consent to participate will be randomized 1:1:2 to receive ZnAg (low dose) : ZnAg (high dose) placebo in a double-blind fashion in addition to standard supportive care. Within the active treatment arm, participants will be randomized to receive either low or high dose ZnAg. - Active treatment with 60 ml low-dose ZnAg (Zn 6 ug/ml and Ag 10 ug/ml; equivalent to 0.6 mg Ag, 0.36 mg Zn), po q12 hours or; - Active treatment with 60 ml high-dose ZnAg (Zn 12 ug/ml and Ag 20 ug/ml; equivalent to 1.2 mg Ag, 0.72 mg Zn), po q12 hours; - 60 ml matching placebo, po q12 hours Participants who become clinically unstable during the course of the study (e.g., requiring high-flow supplemental oxygen or mechanical ventilatory support) per the judgement of the site investigator will be admitted to a hospital and their clinical status (e.g., vital status, hospitalization status, respiratory status, COVID-19 ordinal scale) will continue to be tracked per protocol. ;
