Eligibility
Inclusion criteria
* Patients consider that they are in an early stage of common cold with symptoms of no more than 48 hours duration * Symptom score of equal or more than 1 for for at least one of the symptoms sore throat, runny nose and blocked nose on a 0-3 verbal rating scale * Total symptom score of equal or less 9 for symptoms headache, muscle ache, chilliness, sore throat, blocked nose, runny nose, cough, and sneezing measured on a 0-3 verbal rating scale * Patients agree to refrain from taking any products intended to prevent, intervene in, or treat cough/colds/flu, starting at study entry and continuing through day 10 (e.g. those containing zinc, Echinacea); use of a daily multivitamin is allowed.
Exclusion criteria
* Known hypersensitivity or are allergic to any component of the test device * Clinically significant cardiovascular, endocrinological, neurological, respiratory, gastrointestinal disease or history or any current disease that is considered by the investigator as a reason for exclusion e.g. current allergic rhinitis, chronic obstructive pulmonary disease * Severe nasal septum deviation or other condition that could cause nasal obstruction such as the presence of nasal polyps. * History of nasal or sinus surgery that in the opinion of the investigator may influence symptom scores * Taking any prescribed medication other than for contraception, that is considered by the investigator as a reason for exclusion e.g. systemic steroids, intranasal medicines, antibiotics * Common cold or flu like symptoms for more than 48 hours. * Recent (within the previous 2 days) intake of a common cold medicine that in the opinion of the investigator may influence symptom scores (analgesics, nasal decongestants, cough medicines) * Current smoker (more than 10 cigarettes a day)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total Symptom Score (TSS) Over Days 2 to 4 (TSS2-4) | Days 2, 3 and 4 | The total symptom score (TSS) is the sum of the 8 single common cold symptom scores consisting of 3 systemic (headache, muscle ache and chilliness) and 5 local (sore throat, blocked nose, runny nose, cough and sneezing) symptoms. Each common cold symptom was scored on a 4-point ordinal scale: * 0 = symptom not present * 1 = mild symptom (I can feel it but it has not disturbed or irritated me) * 2 = moderate symptom (symptom has disturbed and irritated me some of the time) * 3 = severe symptom (symptom has disturbed and irritated me most of the time) The mean over days 2 to 4 (TSS2-4) was calculated as (TSS2 + TSS3 + TSS4)/3 where TSS2, TSS3 and TSS4 are the total symptom scores calculated for days 2, 3 and 4 respectively. TSS2-4 ranges from 0 (no symptoms) to 24 (severe symptoms). |

Outcome results
Total Symptom Score (TSS) Over Days 2 to 4 (TSS2-4)
The total symptom score (TSS) is the sum of the 8 single common cold symptom scores consisting of 3 systemic (headache, muscle ache and chilliness) and 5 local (sore throat, blocked nose, runny nose, cough and sneezing) symptoms. Each common cold symptom was scored on a 4-point ordinal scale: * 0 = symptom not present * 1 = mild symptom (I can feel it but it has not disturbed or irritated me) * 2 = moderate symptom (symptom has disturbed and irritated me some of the time) * 3 = severe symptom (symptom has disturbed and irritated me most of the time) The mean over days 2 to 4 (TSS2-4) was calculated as (TSS2 + TSS3 + TSS4)/3 where TSS2, TSS3 and TSS4 are the total symptom scores calculated for days 2, 3 and 4 respectively. TSS2-4 ranges from 0 (no symptoms) to 24 (severe symptoms).
Time frame: Days 2, 3 and 4
Population: Full analysis set (FAS) which included all randomised patients who used at least one dose of trial treatment, who provided a baseline total symptom score (TSS) as well as any post-treatment data for the primary endpoint.
