Recruiting studies
- NCT06230458Recruiting
FeNO breath test to help diagnose asthma
This trial is testing whether a simple breath test called FeNO can help doctors diagnose asthma more accurately. It's for people who have symptoms that might be asthma, but haven't been diagnosed yet.
Rotterdam, South HollandAges 18 years+ - NCT05985330Recruiting
Study of FeNO as a marker for immunotherapy response in lung cancer
This trial is testing whether a simple breath test (FeNO) can predict how well immunotherapy works in people with advanced lung cancer who haven't had treatment before. It's for patients whose tumors have high PD-L1 levels and who will receive immunotherapy alone.
DijonAges 18 years+ - NCT06672952Recruiting
Citrus compound for exercise, blood flow, and stress in overweight adults
This study looks at whether a natural citrus compound called glucosyl-hesperidin (CitraPeak) can boost your exercise performance, improve blood flow, reduce stress, and sharpen thinking. Researchers want to see if it works differently for people who are moderately overweight or mildly obese.
Saint Charles, MissouriAges 18–50 - NCT06690801Recruiting
Nitric oxide breathing gas for children with lung failure
This trial tests whether adding a breathing gas called nitric oxide to standard care helps children with severe lung failure (ARDS) recover faster. It is for children on a breathing machine who still have low oxygen levels.
Los Angeles, CaliforniaAges birth–21 years - NCT06950294RecruitingEarly Phase 1
Inhaled nitric oxide for pneumonia patients on a ventilator
This study tests an inhaled gas (iNO300) given through your breathing tube to improve oxygen levels in critically ill patients with pneumonia. You may qualify if you are on a ventilator and have been diagnosed with pneumonia within the last 3 days.
Boston, MassachusettsAges 18 years+ - NCT07228026Recruiting
Device to Monitor Asthma by Measuring Nitric Oxide in Breath
This trial tests a handheld device that measures nitric oxide in your breath to see if it can help monitor asthma. You may qualify if you have uncontrolled asthma and can use the device at home.
Stockton, CaliforniaAges 5–100 - NCT07328035Recruiting
Asthma remission in adults with severe asthma
This study looks at whether adults with severe asthma in Thailand can reach a state where their asthma symptoms go away (remission). You may join if you have severe asthma and can do the required breathing tests.
Pathum ThaniAges 18 years+ - NCT07351916Recruiting
Asthma remission study for mild-to-moderate asthma
This study looks at whether adults with mild-to-moderate asthma can achieve remission. Remission means your asthma symptoms go away or become very well controlled. You will need to do breathing tests to take part.
Pathum Thani, Changwat Pathum ThaniAges 18 years+ - NCT07485231Recruiting
Nitric oxide and blood vessel function in women with PTSD
This study tests how well blood vessels work in women with PTSD by measuring nitric oxide levels. It may help understand why PTSD affects heart health and could lead to better treatments.
Minneapolis, MinnesotaAges 18–40 - NCT07614906Recruiting
Nitric Oxide Levels to Predict Blood Vessel Spasms After Brain Bleeding
This study examines whether a substance called nitric oxide in brain fluid can help doctors predict who will develop dangerous blood vessel tightening after a subarachnoid hemorrhage—a serious type of brain bleeding. The goal is to find an early warning sign so doctors can intervene faster.
Boston, MassachusettsAges 18 years+ - NCT06164639Enrolling by invitation
Biomarkers and causes of lung injury from reflux
This study looks at why some people on breathing tubes develop lung damage from stomach acid getting into the lungs. It may help find better ways to prevent or treat this injury.
ShanghaiAges 18–99 - NCT04903535Enrolling by invitation
Nitric oxide test using a skin measurement method
This study measures a substance called nitric oxide (related to blood vessel function) by checking how it changes in skin samples. It mainly needs volunteers who are not pregnant and can safely provide the required samples, to help researchers understand how well this measurement method works.
Indianapolis, IndianaAges 1 day–75 years - NCT06499844RecruitingEarly Phase 1
Tests to measure blood flow in skin
This study looks at how blood vessels in the skin widen in response to a natural chemical called nitric oxide. By testing healthy young adults, researchers hope to improve a simple skin test that could one day help detect early blood vessel problems.
Iowa City, IowaAges 18–30

Common questions
- Are there clinical trials for nitric oxide?
- Yes. Clin2 currently lists 37 recruiting nitric oxide studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a nitric oxide trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a nitric oxide trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
