Nasal spray for asthma symptoms from colds
Part of Immune system & allergy, Lungs & breathing clinical trials.
This trial tests if an investigational nasal spray (ETH47) can reduce asthma symptoms triggered by a common cold virus (rhinovirus). You will be exposed to the virus in a safe setting to see if the spray helps control your asthma.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.

- You test negative for the specific cold virus used in the study (RV-A16).

This trial tests an experimental medicine called RIG-101 in healthy adults and adults with asthma. The goal is to see if it can safely prevent or reduce asthma worsening after exposure to a common cold virus (rhinovirus).
This study looks at how the common cold virus affects people with COPD to find new treatments. If you have moderate COPD and your symptoms flare up when you catch a cold, you may be able to help.
This trial tests a nasal spray, INNA-051, that may help your nose and airways fight off viruses that cause respiratory infections like colds and flu. It is for healthy adults aged 18-45 who are around many people and may be exposed to germs.
This trial tests a new nasal spray (AD17002) for people with moderate to severe eosinophilic asthma, a type of asthma with high eosinophil blood cells. The spray is self-administered at home, and the study aims to see if it is safe and helps control asthma.
This study looks at how well a nasal spray called RHINOSEDAL works for people whose nose suddenly gets blocked, such as from a cold, allergies, or sinus trouble. It aims to see if the spray helps relieve the blockage within 48 hours of it starting.
This Phase 2 study tests a “viral” treatment meant to reprogram the lining of your nose to reduce allergy-like immune responses. It is testing whether this approach is safe and can help people with cat allergy (with or without asthma) or compare against healthy people.
