InnsbruckAges 40 years+ - NCT03949400Recruiting
Exercise therapy and a soft knee brace for knee arthritis
This study tests whether an exercise program plus education, along with a soft brace, helps improve symptoms and function in adults with knee osteoarthritis. It may help people who have knee pain by combining movement training with daily support.
Aalborg, NothernAges 18 years+ - NCT04088682Recruiting

Beijing, Beijing MunicipalityAges 18 years+ - NCT04209244Recruiting
Fish oil for cholesterol and side effects in ALL patients
This trial studies whether fish oil can improve cholesterol levels and reduce side effects in children and young adults with acute lymphoblastic leukemia (ALL) who are in lower-risk groups. If you fit the risk category, you may be asked to add fish oil as part of the study to see if it helps your lab results and well-being.
AalborgAges 1–45 - NCT04330456Recruiting
Radiation plus surgery for first soft tissue sarcoma
This trial studies a treatment plan for newly diagnosed soft tissue sarcoma that combines precisely targeted radiation before surgery and conformal radiation after surgery. It may help by improving tumor control while allowing the surgeon to remove the tumor safely.
Saint PetersburgAges 18–75 - NCT04541862Recruiting
ICU patient information database for adults
This trial collects and studies health information from people who are critically ill and admitted to an intensive care unit. It may help doctors learn how to better care for ICU patients in the future.
TaipeiAges 20 years+ - NCT04538859Recruiting
Study of causes of flare-ups and death in bronchiectasis
This study looks at what factors are linked to flare-ups and serious outcomes in people with non–cystic fibrosis bronchiectasis. You may be followed because your lung scans and recent stability help researchers understand what predicts worsening.
Hong Kong, Please SelectAges 18 years+ - NCT04665674Recruiting
Study of adults with pulmonary Langerhans cell histiocytosis
This study follows adults with a specific lung condition to better understand how it behaves over time. If you have the right diagnosis, joining could help researchers learn what to expect and how to manage it.
ParisAges 18 years+ - NCT04875819RecruitingPhase 4
HIV vaccine safety check for meningitis and pneumonia shots
This trial studies how safe and how well the body’s immune system responds to meningococcal and pneumococcal vaccines in adults living with HIV. It may help confirm these vaccines work properly and are safe for people on HIV treatment.
HvidovreAges 18 years+ - NCT03869619Recruiting
Real-life data study for adults with recent lymphoma
This study collects “real-world” health information about adults whose lymphoma was diagnosed within the last 6 months. It aims to better understand lymphoma types and how patients do over time, using data from everyday care rather than testing a new drug.
ArrasAges 18 years+ - NCT03335644Recruiting
Internet-based health study for people 15 and older
This study gathers health information through an online program. It may help researchers understand how diet and lifestyle affect health over time.
Bobigny, Seine Saint DenisAges 15 years+ - NCT05025098RecruitingPhase 2
Targeted treatment versus standard care for older blood cancer patients
This Phase 2 trial compares a “precision” treatment plan with standard therapy for older adults with AML or MDS. It aims to improve outcomes while using treatments that may be better suited for people who cannot have intensive chemotherapy.
LørenskogAges 60 years+ - NCT05043571RecruitingPhase 1
CAR T-cell therapy for relapsed T-cell leukemia
This early-phase trial tests a lab-made immune cell treatment (CAR T-cells) aimed at T-cell leukemia that has come back or did not respond. It may help by targeting leukemia cells with a specific marker (CD7), especially in patients who failed standard treatment.
SingaporeAges 6 months–65 years - NCT03094429RecruitingPhase 2/Phase 3
Testing NaBen add-on to clozapine for tough schizophrenia symptoms
This trial tests whether adding NaBen (a supplement-like medicine) to clozapine can improve “residual” symptoms in adults with difficult-to-treat schizophrenia. The study also checks safety and the best dose, using a placebo (inactive pill) for comparison.
Pasadena, CaliforniaAges 18–55 - NCT05047133RecruitingPhase 2/Phase 3
Early TXA treatment for adult hip fracture surgery
This study tests whether giving a blood-clot-reducing medicine (TXA) early after an adult hip fracture helps reduce bleeding and related problems around surgery. It may help some patients getting operative fixation by improving safety during recovery.
Grand Blanc, MichiganAges 18 years+ - NCT04179929Recruiting
