Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention is an aqueous buffered solution of povidone-iodine (PVP-I) or matching placebo contained in a 30 mL bottle closed with a traditional nasal spray pump.
This 2 stage study consists of:
Stage 1: An open-label Phase 1 study in ten (10) healthy volunteers at a single site to investigate safety and iodine adsorption. Participants will receive a total of 21 doses, over 6 days; 4 times on Days 1,2,3,4,5 and 1 time on the morning of Day 6. 1 dose consists of 8 x 140µL pump actuation's (4 into each nostril). Each dose will be administered in approximately 4 hour intervals.
Stage 2: a two site, randomised, double-blind, placebo-controlled safety and efficacy study in 258 participants exhibiting the common cold. Participants will receive a total of 21 doses, over 5-6 days; the time that a participant is dosed on Day 1 will determine how many doses per day will be required. 1 dose consists of 8 x 140µL pump actuation's (4 into each nostril). Each dose will be administered in approximately 4 hour intervals.
The adherence of dosing in both stages will be monitored by the return of the used product and via diary entries in a dosing diary in Stage 1, and via a webapp diary in Stage 2.
Intervention code [1] 301753 0
Treatment: Drugs
Comparator / control treatment
The placebo is a solution without povidone-iodine, containing BP and USP approved inactive excipient's, coloured with a TGA approved dye to mimic the colour of the active product, closed in a 30 mL bottle with a traditional nasal spray pump.
Control group
Placebo

Outcomes
Primary outcome [1] 306622 0
Stage 1 Outcome.
Measurement of systemic iodine exposure after Nasodine treatment and again after a 5 day course of treatment.
Timepoint [1] 306622 0
Blood samples taken before and after the first and last dose administration are to be analysed for serum iodine. Urine collected before and after the first and last dose administration are to be analysed for urine iodine. T3, T4 and TSH will be measured before treatment and after 35 days to determine any significant change in thyroid function.
Primary outcome [2] 306656 0
Stage 2:
Measurement of cold symptom severity over a 5-day treatment period calculated from the daily WURSS-21 scores for each subject.
Timepoint [2] 306656 0
Partiicpants will record cold symptoms, using daily WURSS-21 questionnaires, in an electronic diary from which the difference between Nasodine and placebo participant responses can be assessed. This will be assessed at enrollment on Day 1 and daily up to and including Day 14.
Secondary outcome [1] 349042 0
Assessment of the safety and tolerability of multiple doses of Nasodine over 5 days using the proposed treatment regimen.
Examples of known/possible adverse events include; shortness of breath, itching, red skin rash, lip swelling, throat swelling, possible thyroid dysfunction, changes in voice, and local nasal discomfort and irritation.
Timepoint [1] 349042 0
Adverse events, vital signs and blood test results will be assessed for determination of general tolerability. Vital signs, nasal examinations and adverse events will be collated for determination of safety.
Adverse events will be assessed from dosing (Day 1) until the end of study visit (EOS) on Day 35 for both stages. AE probes will be performed while participants are in house on Day-1, Day 1, Day 6 and Day 35 for Stage 1.
AE probes will be performed while participants are in house on Day-1, Day 1, Day 6, Day 14 and Day 35 for Stage 2. Subjects will also be probed for AEs daily on the webapp application from Day 1 through to Day 14.
Vital signs will be assessed at screening, Day -1, Day 1, Day 6 and at the EOS visit on Day 35 in Stage 1.
Vital Signs will be assessed on Visit 1 (screening/Day 1), Day 6, Day 14 and the EOS visit on Day 35 for Stage 2.
Blood tests (Haematology and Serum Chemistry) will be performed at screening, Day 1, Day 6 and at the EOS on day 35 for Stage 1.
Blood tests (Haematology and Serum Chemistry) will be performed at Visit 1, Day 6 and at the EOS on Day 35 for Stage 2.
Nasal examinations will be performed at Screening, Day -1, Day 1, Day 6 and at the EOS on Day 35 for Stage 1.
Nasal examinations will be performed at Screening, Visit 1, Day 6, Day 14 and at the EOS on Day 35 for Stage 2.
