Traditional Chinese medicine plus inhalers for cough variant asthma
Part of Immune system & allergy, Lungs & breathing clinical trials.
This study tests whether adding a traditional Chinese medicine (Liqin Zhike Formula) to standard inhaler treatment (ICS/LABA) helps people with cough variant asthma. It may improve cough control and overall outcomes.
Summary written for real people, not researchers, by Clin2.

This study looks at how asthma affects people in China and tries to find patterns that might help predict which treatments work best. If you have asthma and are between 18 and 75, you may be able to join.
This trial tests a new inhaled medication called LQ036 to see if it can help people whose asthma is not well controlled with their current inhalers. Participants must have had at least one severe asthma flare-up in the last year and show signs of airway inflammation.
This trial tests whether a Traditional Chinese Medicine technique called moxibustion can help reduce asthma attacks and improve control. If you have asthma that is not well managed, this treatment might offer an additional option to ease your symptoms.
This study tests a new three-part asthma inhaler (CHF 5993) in people whose asthma isn't well-controlled even though they're already using two standard asthma medicines together. The goal is to see if adding this new medicine helps control asthma better.
This study tests an investigational drug (called JNJ-95597528) taken as a pill, to see if it can reduce asthma attacks and improve control in people with moderate to severe asthma that isn't well controlled by current inhalers. It may be a new option to help reduce airway inflammation and improve your breathing.
This study is following people with asthma to learn how traditional Chinese medicine might help manage the condition. It is an observational study, so you will not receive a new treatment, but your health will be tracked over time.
