简要总结

The study aims to determine the safety and efficacy of povidone-iodine (PVP-I) containing nasal sprays as compared to isotonic saline nasal sprays in COVID-19 positive patients. The primary outcome measure is SARS-CoV-2 viral titers in the nasal cavity and nasopharynx. In vitro studies have shown PVP-I to be highly virucidal against the viruses which cause SARS and MERS. Additionally, clinical studies have shown PVP-I saline sprays to be well tolerated in human subjects. PVP-I oral rinses and sprays have been trialed as methods to reduce the incidence and symptoms of viruses which cause the "common cold."

研究组 & 干预措施

Povidone-Iodine 2%

Experimental

Participants will administer PVP-I 2% nasal spray for 5 days. Nasopharyngeal swabs will be taken on Day 1 at baseline, Day 1 at four hours post-first dose, and Day 5.

Participants will complete a daily symptom journal from Day 1 through Day 5.

干预措施: Povidone-Iodine 2% (Drug)

Povidone-Iodine 0.5%

Experimental

Participants will administer PVP-I 0.5% nasal spray for 5 days. Nasopharyngeal swabs will be taken on Day 1 at baseline, Day 1 at four hours post-first dose, and Day 5.

Participants will complete a daily symptom journal from Day 1 through Day 5

干预措施: Povidone-Iodine 0.5% (Drug)

Isotonic saline 0.9%

Placebo Comparator

Participants will administer two sprays of isotonic saline nasal spray for 5 days. Nasopharyngeal swabs will be taken on Day 1 at baseline, Day 1 at four hours post-first dose, and Day 5.

Participants will complete a daily symptom journal from Day 1 through Day 5.

干预措施: Isotonic saline 0.9% (Drug)

结局指标

主要结局

Mean Cycle Threshold (Ct) Values Through Day 3 as a Measure of Change in Viral Titers of SARS-CoV-2

时间窗: Day 1 (baseline), Day 1 (1 hour), Day 3

Nasopharyngeal swabs were obtained and quantitative reverse transcription-polymerase chain reaction (RT-PCR) testing was performed to determine the viral load in the nasopharynx. Cycle threshold (Ct) denotes how many PCR cycles are required before the SARS-CoV-2 viral RNA reached a detectable level. Higher Ct values correspond to lower viral copy numbers. For reference, Ct values of 20 correspond to \~2.12 x 106 viral copies per milliliter, while a Ct value of 40 is undetectable and is considered the lower limit of detection of this RT-PCR test for SARS-CoV-2.
