TRIAL DESCRIPTION
Public title FBP-007_Nasodine for Elimination of COVID-19 Shedding study “NASO-ELOCS”
Official scientific title Reduction of nasal shedding of SARS-CoV-2 in COVID-19 positive patients by the use of Nasodine® (povidone-iodine 0.5%) Nasal Spray.
Brief summary describing the background and objectives of the trial The study is a double-blinded, randomised, controlled Phase 2 study. Enrolled subjects will be randomised 2:1 to Nasodine treatment or placebo (Control) by household. The primary aim of the trial will be to show that frequent Nasodine application (every 2 waking hours, up to eight-times-daily) over 3 days leads to a reduction in nasal shedding from culture-positive COVID-19 patients, as measured by the reduction (versus baseline) in log10 of TCID50 titres on Days 2-4 compared with placebo. Secondary objectives will be to determine if the treatment leads to: (a) people clearing the virus from their nasal passages more quickly based on culture; (b) reduction in the time to a negative RAT (rapid antigen test) test; (c) overall elimination of SARS-CoV-2 from the upper respiratory tract within 5 days, based on a combined throat/nasal swab; and (d) a beneficial impact on symptoms.

STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person allocating the participants to the intervention arms Masking If masking / blinding was used
Parallel: different groups receive different interventions at same time during study Randomised Stratified allocation where factors such as age, gender, center, or previous treatment are used in the stratification Allocation was determined by the holder of the sequence who is situated off site Masking/blinding used Care giver/Provider,Outcome Assessors,Participants
INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group FBP007 a total dose of 1.12 mL based on 4 sprays per nostril applied every 2 hours for a total of 20 doses over 3 days Nasodine Nasal Spray, containing povidone-iodine 0.5%, plus excipients and buffers, in a nasal spray bottle nominally holding 25 mL and with a nasal spray pump designed to deliver 0.14 mL per actuation, for a total dose of 1.12 mL based on 4 sprays per nostril 100
Control Group FBP007 4 sprays per nostril applied every 2 hours for a total of 20 doses over 3 days The purpose of placebo control is to determine the pure pharmacological effect of the drug and perform reliable assessments by distinguishing AEs caused by drugs from those caused by natural progression of disease or other causes[2]. In addition, using placebo enables randomization and blinding process and minimizes the bias in subject management and data analysis. 50 Placebo

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome (1) Impact on viral shedding after 20 doses of Nasodine over 3 days (IITi): The use of Nasodine every 2 hours for 20 doses will be assessed by the comparison of the quantity of culturable (infectious) virus before treatment with the amount of culturable virus after initiating the treatment regimen. Mid-turbinate swabs will be collected before the first treatment and again on days 2 and 3 between treatments and again on day 4 when treatment has been concluded. Quantitative culture will be performed via TCID50 assay using Vero cells and a half log10 dilution series in triplicate. Plates will be scored by microscopic inspection and expressed as TCID50/mL. The least square mean (average) of the TCID50/ML for each subject will be calculated and the percent reduction from baseline determined. The average reduction for the Nasodine population will be compared against the placebo population. The result will be expressed as the increase in log reduction in the Nasodine population over the placebo population. Mid-turbinate swabs will be collected before the first treatment and again on days 2 and 3 between treatments and again on day 4 when treatment has been concluded.
Secondary Outcome (1) URT clearance (IITi): Nose and throat swabs will be collected on day 5 and be combined and cultured to determine the presence of culturable (infectious) virus for each subject. The proportion of subjects shedding infectious virus in the Nasodine population will be compared against the proportion of subjects shedding infectious virus in the placebo population. The result will be expressed as the improvement of Nasodine against placebo: Day 5
Secondary Outcome (2) Symptom severity on Day 3 (ITT): Subjects will be asked a series of questions by study staff to ascertain the severity of their symptoms. An outline of the questions is presented in Appendix 1. Subjects will be surveyed on Day 1 prior to commencing treatment and again on Day 3 when the study staff visit the subject’s residence. (we need a protocol of data analysis here) Day 3
Secondary Outcome (3) Symptom severity on Day 4 (ITT): Subjects will be asked a series of questions by study staff to ascertain the severity of their symptoms. An outline of the questions is presented in Appendix 1. Subjects will be surveyed on Day 1 prior to commencing treatment and again on Day 4 when the study staff visit the subject’s residence. (we need a protocol of data analysis here) Day 4
Secondary Outcome (4) Symptom severity on Day 5 (ITT): Subjects will be asked a series of questions by study staff to ascertain the severity of their symptoms. An outline of the questions is presented in Appendix 1. Subjects will be surveyed on Day 1 prior to commencing treatment and again on Day 5 when the study staff visit the subject’s residence. (we need a protocol of data analysis here) Day 5
Secondary Outcome (5) Time to cessation of shedding (ITT): RAT negative: Subjects will undergo a RAT using an anterior nasal swab each day from Day 1 to Day 5. The average duration to cessation of shedding will be calculated for both the Nasodine and placebo populations and the difference in days between the groups reported: Reduction in time to cessation = average Nasodine duration – average placebo duration Day 1 to Day 5
