Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention is an aqueous buffered solution of 0.5% povidone-iodine (PVP-I) contained in a 30 mL bottle closed with a traditional nasal spray pump.
Subjects will receive a single dose to their nasal passages, administered by the investigator.
The amount a subject receives consists of 8 x 140µL pump actuations (4 into each nostril), being 1.12 mL total volume.

Outcomes
Primary outcome [1] 325853 0
The titres of viable virus in mid-turbinate swab samples will be assessed by inoculation of Vero cells in tissue culture and measurement of viral RNA copies at 96 hours after inoculation. RT- PCR will be used to measure the number of RNA copies in serial dilution cell culture after 96 hours. The difference in growth between the baseline cell cultures and the Nasodine swabs taken post-treatment will be the measurable treatment effect. Specifically, the primary endpoint (EP) will be the reduction in growth between the baseline swab and the growth from the first swab taken 5 minutes after the Nasodine dose, (both assessed in cell culture after 96 hours).
Timepoint [1] 325853 0
The primary end point is the growth measured from the swab at 5 minutes after Nasodine dosing compared to the growth from the baseline swab.
Secondary outcome [1] 390547 0
Ongoing viral inactivation or viral recovery will be assessed by the collection of mid-turbinate swabs 60 minutes after the Nasodine treatment. The titre of viable virus in these mid-turbinate swab samples will be compared with the titre measured in the baseline samples and those collected 5 minutes after Nasodine treatment.
Timepoint [1] 390547 0
Secondary endpoint is the difference in titre between swabs collected before Nasodine treatment and those collected 60 minutes after treatment.

Summary
Brief summary
The primary purpose of this pilot study is to provide an indication that the in vitro disinfectant activity seen against the SARS-CoV-2 virus translates to disinfection of the nasal cavity in vivo of COVID-19 patients in South Africa.
Other objectives include collecting data to guide follow-on clinical studies and to provide insights as to mode of action. Overall, the study will provide important insights into the potential role for a PVP-I nasal spray in managing the risk of infection by the virus.
