L-citrulline supplement for overweight adults with later-onset asthma
Part of Hormones & metabolism, Immune system & allergy, Lungs & breathing clinical trials.
This Phase 2 trial tests whether adding L-citrulline can improve asthma control in overweight adults whose asthma started later in life. It compares your asthma symptoms and lung testing results to see if the supplement helps when asthma is already being treated.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have a doctor-confirmed diagnosis of asthma
- Your asthma numbers at the study start must be fairly preserved (FEV1 at least 50% of predicted), and you must be able to do breathing tests reliably
- Your body mass index (BMI) must be 30 or higher
- You must be using asthma controller medicine regularly for at least 1 month (such as inhaled steroids, or combinations like inhaled steroid plus a long-acting bronchodilator; biologics are allowed)
- You should not be a recent smoker (10 pack-years or less, and no smoking in the last 3 months)
- You must not have had certain recent asthma flare-ups, steroid bursts, or infections, and you must not have conditions that block study participation (like kidney failure or untreated sleep apnea)

This Phase 2 study tests anti-inflammatory lipid mediators in people with asthma. You may be eligible if your asthma is not well controlled despite regular inhaler use and you meet the specific lung function and health criteria.
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.
