NCT04347954

Brief Summary

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."

Outcome Measures

Primary Outcomes (1)

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

    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.

    Day 1 (baseline), Day 1 (1 hour), Day 3

Secondary Outcomes (10)

  • Count of Participants Experiencing Adverse Events of Interest After Nasal Sprays

    Assessed on days 3 and 5

  • Count of Participants Experiencing Fevers as a Measure of Frequency of Symptoms Related to SARS-CoV-2

    Assessed on days 3 and 5

  • Count of Participants Experiencing Chills as a Measure of Frequency of Symptoms Related to SARS-CoV-2

    Assessed on days 3 and 5

  • Count of Participants Experiencing Fatigue as a Measure of Frequency of Symptoms Related to SARS-CoV-2

    Assessed on days 3 and 5

  • Count of Participants Experiencing Loss of Sense of Smell as a Measure of Frequency of Symptoms Related to SARS-CoV-2

    Assessed on days 3 and 5

  • +5 more secondary outcomes

Study Arms (3)

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.

Drug: Povidone-Iodine 2%

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

Drug: Povidone-Iodine 0.5%

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.

Drug: Isotonic saline 0.9%

Interventions

Two sprays to each nare of PVP-I 2% via nasal spray bottle, four times a day

Povidone-Iodine 2%

Two sprays to each nare of PVP-I 0.5% via nasal spray bottle, four times a day

Povidone-Iodine 0.5%

Two sprays to each nare of isotonic saline (0.9% NaCl) via nasal spray bottle, four times a day

Isotonic saline 0.9%
