简要总结
This study is a two-arm, randomized, 2-phase study. Phase I will be double blinded clinical trial of the safety and efficacy of an antiseptic mouthwash solution on reducing SARS-CoV-2 load in COVID 19+ adult individuals. Phase II is designed as an open label trial, and all subjects will receive the active mouthwash.

- •Male or female, aged 18 years and older.
- •Clinical diagnosis of COVID-19 infection confirmed with a positive point of care test.
- •Confirmed diagnosis within 5 days of baseline visit (within 5 days of COVID-19 test) and at least one clinical COVID-19 symptom [*Signs and symptoms of COVID-19 present at illness onset vary, but over the course of the disease, most people will experience the following: fever or chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste of smell, sore throat, congestion or runny nose, nausea or vomiting and diarrhea.]

研究组 & 干预措施
Povidone-iodine 0.5% antiseptic mouth rinse
Subjects will be asked to rinse/gargle one time with 10 mL of Povidone-iodine 0.5% antiseptic mouth rinse for 30 seconds.
干预措施: Mouth rinse (Drug)
Placebo
Subjects will be asked to rinse/gargle one time with 10 mL of placebo mouth rinse for 30 seconds.
干预措施: Mouth rinse (Drug)
结局指标
主要结局
[PCR Saliva] Percent Change From Baseline Ct Viral Targets
时间窗: 60 minutes after intervention
The primary endpoint is the percentage reduction of SARS-Co-V-2 load in saliva at 60 minutes (post-intervention) compared to baseline between the PVP-I mouthwash versus the placebo mouthwash. For this outcome, Cycle Threshold is a proxy for SARS-Co-V-2 load. A positive percent change from baseline Cycle Threshold indicates a decrease from baseline SAR-Co-V2. \[Quick SARS-CoV-2 rRT-PCR Kit (Zymo Research, Cat. No. R3011)\].
次要结局
- [PCR Saliva] Percent Change From Baseline Cycle Threshold at 5 and 30 Minutes Post Intervention(5 and 30 minutes post-intervention)
