Recruiting studies
- NCT05769140Recruiting
Study how high altitude affects heart and breathing measures
This study looks at how exposure to high altitude changes measurements related to your heart and breathing. It may help scientists better understand health effects of altitude so they can improve safety and care.
Courmayeur, AostaAges 18 years+ - NCT07118462RecruitingPhase 4
Acetazolamide, high altitude, and plasma volume study
This trial tests how acetazolamide affects your body's fluid levels at high altitude. It might help understand if the drug can prevent altitude sickness.
BishkekAges 18–44 - NCT07536477Recruiting
High-flow oxygen versus standard oxygen for altitude lung swelling
This trial tests whether high-flow oxygen (delivered through a special nasal tube) works better than standard oxygen therapy for a condition called high-altitude pulmonary edema (HAPE)—fluid buildup in the lungs caused by rapid ascent to high altitude. The study aims to see which approach helps patients breathe better and recover faster.
Xigazê, TibetAges 18 years+ - NCT07014501Recruiting
Stroke recovery and trach tube removal at different altitudes
This trial studies how well stroke patients with a breathing tube (tracheostomy) can have it removed. It looks at genes and blood oxygen levels, and compares patients at different altitudes to find the best timing for removal.
Kunming, YunnanAges 18–75 - NCT06152744Recruiting
Testing ECMO lung function at high altitude
This study looks at how well the ECMO machine works in high-altitude areas. It tests the oxygen exchange in the machine to help improve care for patients at high elevations.
Beijing, Beijing MunicipalityAges 18–70 - NCT07193771Recruiting
Altitude and Outcomes in Children with ARDS
This study looks at how elevation (altitude) affects the recovery of children with a serious lung condition called ARDS who are on a breathing machine in the intensive care unit.
Sucre, Chuquisaca DepartmentAges 1 month–18 years - NCT07063732Recruiting
Ketone drink, high altitude, and brain blood flow during exercise
This trial tests whether a ketone monoester supplement affects brain blood flow and exercise performance at high altitude. It may help us understand how to support brain function during altitude exposure.
Bishop, CaliforniaAges 18–35 - NCT06852924Recruiting
Inhaled nitric oxide for HAPE treatment trial
This trial tests if inhaled nitric oxide helps people with high-altitude pulmonary edema (fluid in the lungs from high altitude). It may offer a new treatment option for those with mild to moderate symptoms.
Lhasa, TibetAges 18–65 - NCT07612956Recruiting
High-altitude training effects on teenage rowers' performance
This study tests whether training at high altitude for 4 weeks helps teenage male rowers improve their sport performance, fitness, and heart and lung health. Researchers will measure changes in body composition, rowing ability, and how well your heart and lungs work.
Macao, MacaoAges 12–19 - NCT07142590Recruiting
Iron needs in people living at high altitude
This study measures how much iron your body absorbs and loses if you live at high altitude. It helps researchers understand iron requirements for people in this environment, using a new testing technique.
Zurich, Canton of ZurichAges 18–45 - NCT07755384Recruiting
Stomach and throat exam study at high altitude
This study looks at what doctors see in the upper digestive tract (stomach and food pipe) of people living at high altitude, using a sedated endoscopy (a camera tube down the throat while you sleep). It helps understand how high altitude affects the digestive system.
Yushu, QinghaiAges 18 years+ - NCT06686693RecruitingPhase 4
IV iron and exercise at high altitude
This study tests whether giving iron through a vein helps you perform better at high altitude. It may help you if you are a healthy adult who exercises regularly.
Natick, MassachusettsAges 18–40 - 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 - 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 - 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.
ErfurtAges 18–65 - NCT06596083Recruiting
Ketone supplement and altitude training study
This study tests whether drinking a ketone supplement helps your body adapt better during a 5-week altitude training program. You would live at high altitude but train at low altitude.
Leuven, Vlaams-BrabantAges 18–35

Common questions
- Are there clinical trials for high altitude?
- Yes. Clin2 currently lists 19 recruiting high 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 high 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 high 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.
