Are you an asthmatic interested in taking part in a clinical trial that could help reduce asthma during a cold?
We are trialling an exciting new nasal spray, which has been developed to reduce cold symptoms. We want to see if it helps reduce asthma symptoms during a cold.
The nasal spray contains the natural and safe product carrageenan, which is a seaweed extract. This extract has been used since the 1950s as a food additive in products such as ice cream. Recently, researchers found that carrageenan spray may reduce the severity of cold symptoms in adults. Carrageenan is thought to work by preventing the cold virus from attaching itself to the lining of the nose. We are trying to find out if applying it as soon as you get a cold can reduce asthma in adults when used together with your usual medications.
The study involves:
- Taking a nasal spray 4 times a day for 10 days, starting the first day of cold symptoms, for up to 2 colds.
- The nasal spray contains either a carrageenan and saline solution, or a saline solution only. You would be randomly assigned one of the two sprays.
- An initial visit of 40 minutes with researchers, followed by up to 3 short visits (15 minutes each), depending on how many colds you have during the 16 week study period. The visits can be either at your home or at the Wellington School of Medicine, Newtown.
- Completing a questionnaire about your respiratory health.
- Filling out a cold symptom diary and asthma control questionnaire (ACQ) when you have a cold.
- Taking your own peak flow readings each day you have a cold.
- Taking a swab of your nose to check for cold viruses (optional).
- Have an allergy test (skin prick test) to find out what environmental allergens you might be allergic to (optional).
