A Nasal Spray With Glucose Oxidase as a Treatment of Common Cold
|Common Cold||Device: Glucose oxidase+5%glucose Device: Saline+5%glucose||Phase 2|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||A Double Blinded Clinical Study Aiming to Shorten an Episode of Common Cold When the Treatment is Started at the Onset of an Episode of Common Cold|
- Reducing Symptoms of a Common Cold [ Time Frame: One week ]
Using the Wisconsin Upper Respiratory Symptom Score (WURSS-21)it is possible to assess if a nasal spray containing glucose oxidase and glucose would be able to reduce symptoms of a common Cold.
WURSS 21 is a validated tool of calculating the degree of common Cold symptoms. It consists of 21 questions (20 questions are possible to evaluate) which are graded from 0 to 7 (worst degree of symptoms). These 20 questions (sum of all symptoms) are evaluated every day, Min value is thus 0 and max value/person/day is 140. It is thus possible to calculate the mean value of sum of symptoms for each day in the both groups.

Placebo Comparator: Saline+glucose nasal spray
A nasal spray with isotone saline + 5% glucose, dosing one puff 5 times daily in each nostril at the first treatment day and thereafter trice daily for a total of one week
Isotonic saline + 5% glucose in a bag-on-valve nasal spray device
Active Comparator: Nasal spray with glucose oxidase+glucose
A nasal spray with 200U/ml of glucose oxidase + 5% glucose. Treatment starts with 5 puffs in each nostril at the first day, and thereafter trhee times daily for a total treatment time of one week.
Device: Glucose oxidase+5%glucose
A hydrogen peroxide producing enzyme
Persons working in a military unit in Boden and persons connected to the Department of Sports Medicine in Umeå were invited to participate in this study. Only persons older than 18 years was included in the study. The persons included received one bottle of study medicine, a home protocol (WURSS 21) and a viral sampling kit. Whenever the included persons were sure that they had received an episode of common cold they were told to perform a viral sampling from the nose, fill in the protocol and start to use the nasal spray several times daily for one week. The treatment was either a) a saline solution with 5% glucose or b) a saline solution with 200U/ml of glucose oxidase and 5%glucose (active treatment group). The combination of glucose oxidase and glucose produces an acid environment, imitating the effect of the normal nasal flora and Human Rhinoviruses are sensitive to an acid environment. After one week of treatment and daily records of the WURSS 21 protocol the persons returned the spray bottles (Bag-on-Valve), the virus vials and the protocols.
A total of 146 persons were included in the study and 98 persons returned protocols.
