Stage 1:
1. A healthy adult (18-55 years old)
2. Exhibit as no clinically relevant abnormalities as determined by past medical history, physical examination, vital signs, and laboratory tests at Screening.
3. Female subjects of childbearing potential must have a confirmed negative pregnancy test at the start of the study (Screening and Day -1) and also agree to abstain from sexual intercourse or use a highly effective method of birth control for the duration of the study and for 90 days after last dose of study drug, as determined by the investigator. Female participants of non-childbearing potential, defined as surgically sterilized (hysterectomy, bilateral oophorectomy or tubal ligation) or clinically documented to be postmenopausal.
4. Male subjects must agree to abstain from sexual intercourse or use a highly effective method of birth control with partners of childbearing potential for the duration of the study and for 90 days after last dose of study drug.
Stage 2:
1. Adult (18-65) participants who have a cold or are coming down with a cold
2. Report at least two of the following cold symptoms – sneezing, runny nose, nasal congestion, or sore throat – and have a total Jackson score of at least 6 points. Jackson scores are simple sums of severity ratings (0 = absent, 1 = mild, 2 = moderate, 3 = severe).
3. Have had cold symptoms for at least 24 hours at the time they commence treatment.
4. Access to a smartphone or tablet.
5. Female subjects of childbearing potential must have a confirmed negative pregnancy test at the start of the study (Screening and Day -1) and also agree to abstain from sexual intercourse or use a highly effective method of birth control for the duration of the study and for 90 days after last dose of study drug, as determined by the investigator. Female participants of nonchildbearing potential, defined as surgically sterilized (hysterectomy, bilateral oophorectomy or tubal ligation) or clinically documented to be postmenopausal.
6. Male subjects must agree to abstain from sexual intercourse or use a highly effective method of birth control with partners of childbearing potential for the duration of the study and for 90 days after last dose of study drug.

4. Is considered too unwell based on global medical assessment
5. Self-reporting of normally very mild cold symptoms with a common cold, including duration of illness of < 48 hours
6. Previous diagnoses of nasal polyps or any ear, nose and throat pathology deemed by the Principal Investigator or delegate to affect assessment of the investigational product

- Primary Outcome Measures
Name Time Method Stage 1 Outcome. <br>Measurement of systemic iodine exposure after Nasodine treatment and again after a 5 day course of treatment.[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.];Stage 2:<br>Measurement of cold symptom severity over a 5-day treatment period calculated from the daily WURSS-21 scores for each subject.[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. ]
