Altitude rehab for COPD: testing lung improvement
This study tests whether spending time at a moderate altitude (like a mountain resort) can help people with COPD breathe easier. It measures how open your airways are using a special test while you do a rehabilitation program.
Bishkek, KyrgyzstanAges 18 years+ - NCT07205523Recruiting
High-altitude blood study for stem cell transplant patients
This study observes how blood and stem cell transplants work for patients with blood diseases at high altitude. It aims to learn more to help future patients.
Xining, QinghaiAges Any age - NCT07216755Recruiting
Breathing training and nitrate for altitude exercise
This study tests whether breathing training and a natural nitrate supplement (from beets) can improve how well you exercise in conditions that simulate high altitude. You'll do cycling workouts while we measure your performance.
Daytona Beach, FloridaAges 18–40 - NCT07312227Recruiting
Pregnancy at high altitude study
This study follows pregnant women living at high altitude in Bolivia to understand how pregnancy differs from those at sea level. It may help improve care for mothers and babies in high-altitude regions.
Boston, MassachusettsAges 18–45 - NCT02391519Recruiting
Study how high altitude affects body energy signaling
This study compares how the body responds to high altitude around the time of a planned C-section, including a signal involved in energy use. It may help researchers understand why pregnancy and blood-vessel function can differ at higher elevations.
Aurora, ColoradoAges 18–45 - NCT07423988Recruiting
Sleep changes at high altitude for Pic du Midi staff
This study looks at how sleep quality changes when you work overnight at high altitude (2877m) at the Pic du Midi observatory, compared to sleeping at home. It helps understand the effects of high-altitude work on rest.
Toulouse, OuiAges 18–65 - NCT07431567Recruiting
How low oxygen affects heart function in healthy adults
This study tests how your heart’s right ventricle handles low oxygen (like at high altitude) in healthy adults. You will be exposed to a low-oxygen environment for a short time to see how your heart responds.
Zurich, Canton of ZurichAges 18–80 - NCT07431554Recruiting
Studying heart function in low oxygen after HAPE
This study looks at how the right side of the heart responds to low oxygen levels in people who have had high altitude pulmonary edema (HAPE) in the past. It will help researchers better understand right heart function.
ZurichAges 18–80 - NCT07431580Recruiting
How low oxygen affects heart function in asthma
This study tests how your heart's right ventricle adapts when you breathe lower-oxygen air (like at high altitude). If you have well-controlled asthma, researchers want to see if your heart handles the challenge differently.
Zurich, Canton of ZurichAges 18–80 - NCT06557928Enrolling by invitation
Study of body and mind changes in the Tibetan plateau
This study looks at how healthy people's bodies and minds adapt when they travel to the high-altitude Tibetan plateau. It aims to help understand the changes and find ways to support people working there.
BeijingAges 18–50 - NCT06133530Enrolling by invitation
Human milk sugars for gut health in Antarctica
This study tests whether natural sugars found in human milk (called HMOs) can improve gut health and the immune system. Researchers are looking for healthy adults who are willing to travel to Antarctica for the study.

Common questions
- Are there clinical trials for altitude?
- Yes. Clin2 currently lists 35 recruiting altitude 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 altitude 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 altitude 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.
