Study drugs for blood-vessel Behçet’s to reduce inflammation
This Phase 2 trial tests tocilizumab and tofacitinib to see if they can better control vascular (blood-vessel) Behçet’s syndrome. It may help by lowering inflammation and reducing complications from aneurysms in the aorta or peripheral arteries.
Beijing, Beijing MunicipalityAges 18–65 - NCT05849389RecruitingPhase 2
Vosoritide for taller growth in girls with Turner syndrome
This Phase 2 study tests vosoritide to help children with Turner syndrome grow taller before puberty. You may be able to join if your child is pre-pubertal, has short height for age, and either has not tried growth hormone or has not responded well to it.
Washington D.C., District of ColumbiaAges 3–11 - NCT05857891Recruiting
Erythropoietin to help clear lung fluid in ARDS
This trial tests whether erythropoietin (EPO), a medicine that affects red blood cell production, can help clear extra fluid from the lungs in people with acute respiratory distress syndrome (ARDS). If it works, it could improve breathing and reduce lung fluid buildup during critical illness.
Wenzhou, ZhejiangAges 18 years+ - NCT05865600Recruiting
PET/CT guided planning for treatment in chronic coronary disease
This trial uses a heart scan (PET/CT) to better estimate blood flow in people with long-term coronary artery disease. It aims to help doctors choose the best treatment strategy and decide who may need more invasive testing or procedures.
Herning, Central JutlandAges 18 years+ - NCT05889559Recruiting
Testing a fluid drainage method to detect leg pressure problems
This study looks at a special drainage measurement (“tissue ultrafiltration”) to better detect and treat acute compartment syndrome, a dangerous increase in pressure in the leg after major injury. It may help doctors identify who needs urgent treatment and improve outcomes after severe leg fractures or crush injuries.
Baltimore, MarylandAges 18–60 - NCT05890599Recruiting
Yoga or health education for ongoing fatigue after COVID
This trial studies whether a yoga program (compared with health education) can reduce persistent tiredness after COVID-19. It may help if your fatigue has lasted at least 12 weeks and you think it started with COVID.
StuttgartAges 18–65 - NCT05902416Recruiting
Testing haplo transplant for older adults with leukemia or MDS
This study looks at using a “half-matched” stem cell transplant (haploidentical transplant) in adults around your age with acute leukemia or MDS. It may help people who cannot find a fully matched donor, but are still eligible for this type of transplant.
