Blood thinner drugs vs aspirin to prevent clot problems
This trial compares apixaban or rivaroxaban (blood thinners) against aspirin to prevent future clot-related complications in people with certain bone marrow diseases (PV, ET, or pre-PMF) that have a specific JAK2 mutation. It may help lower the risk of clots, but it also carefully considers bleeding risk.
AngersAges 18 years+ - NCT05257018RecruitingPhase 2
Chemo plus medicine in the spine to prevent lymphoma brain relapse
This Phase 2 study tests whether adding intrathecal methotrexate (a cancer drug delivered into the spinal fluid) to standard chemo can lower the risk of diffuse large B-cell lymphoma (DLBCL) coming back in the brain or spinal fluid. It is for people with higher-than-usual risk of central nervous system (CNS) relapse.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05201534Recruiting
Math and thinking skills training for school-age children
This trial studies interventions to improve math and cognitive (thinking) skills in elementary school children. It includes both children with math learning difficulties and typically developing children, using tests and MRI brain scans for those who can participate.
Palo Alto, CaliforniaAges 6–12 - NCT05229432Recruiting
Oatmeal meal test to study stomach movement in eosinophilic gastritis
This study looks at how your stomach moves (gastric motility) in people with eosinophilic gastritis, using a special oatmeal meal. The goal is to better understand stomach function and how it may relate to symptoms.
Chicago, IllinoisAges 18–59 - NCT05219110Recruiting
More fluids for children sick with toxin E. coli
This study looks at whether giving extra (hyper) fluids early helps children with a high-risk E. coli stomach infection. The goal is to improve outcomes by supporting the kidneys during the illness.
Birmingham, AlabamaAges 9 months–21 years - NCT05208307RecruitingPhase 2
Belantamab with pomalidomide and dexamethasone after high-risk myeloma transplant
This Phase 2 study tests a treatment combination (belantamab mafodotin, pomalidomide, and dexamethasone) for high-risk multiple myeloma after an autologous stem cell transplant. It aims to improve disease control in people who have certain genetic features or aggressive disease behavior.
Atlanta, GeorgiaAges 18 years+ - NCT05245656RecruitingPhase 2
Rituximab plus chemo plans for older mantle cell lymphoma
This Phase 2 trial studies whether an “extra chemo” schedule (adding cytarabine) can work better than a standard rituximab-bendamustine plan in older people with mantle cell lymphoma. It compares two treatment sequences to see which one helps patients live longer and respond better with acceptable safety.
Seoul, Gangnam-GuAges 60 years+ - NCT00398177Recruiting
Study blood and tissue changes in lymphoma and Hodgkin’s
This study looks at samples of tissue removed during routine procedures to better understand Hodgkin’s disease and non-Hodgkin’s lymphoma. It may help researchers learn more about what these cancers look like in tissue.
Stanford, CaliforniaAges 18 years+ - NCT01629017Recruiting
Long-term follow-up after a stem cell transplant
This study looks at the long-term health effects of hematopoietic (blood-forming) stem cell transplants. It may help doctors better understand and manage late side effects for children and teens after transplant.
Stanford, CaliforniaAges Up to 18 years - NCT01521741Recruiting
Breast cancer lymphedema screening to detect early swelling
This trial looks at whether scheduled measurements can spot early swelling (lymphedema) in people with breast cancer. It may help find problems sooner so treatment or prevention steps can start earlier.
Boston, MassachusettsAges 18 years+ - NCT05180097RecruitingPhase 2
Immunotherapy with stem cell transplant for relapsed Hodgkin lymphoma
This Phase 2 trial tests whether pembrolizumab plus brentuximab works better than standard chemotherapy followed by an autologous stem cell transplant for people whose classic Hodgkin lymphoma has come back or did not respond. It may help by improving cancer control before and around stem cell transplant and by comparing outcomes between the two treatment approaches.
Concord, New South WalesAges 18 years+ - NCT05170412Recruiting
Diet habits study for adults with sickle cell disease
This study asks adults with sickle cell disease about what they eat and their eating routines. The goal is to understand diet patterns in sickle cell and how they may relate to health, which could help future care and guidance.
Bethesda, MarylandAges 18–120 - NCT05170399RecruitingPhase 4
Testing how cancer vaccines work in B-cell blood cancers
This study measures how well certain vaccines stimulate the immune system in people with B-cell blood cancers such as CLL and different types of lymphoma or Waldenström macroglobulinemia. It may help doctors better predict who will benefit most from vaccination and improve vaccine planning for these conditions.
Bethesda, MarylandAges 18–90 - NCT05189925RecruitingPhase 1
Correcting a missing immune enzyme using an mRNA cell therapy
This early-phase trial tests whether an mRNA-based treatment can correct a key immune problem in people with chronic granulomatous disease (CGD). It may help your immune cells work better against infections, but this is mainly to check safety and early signs of benefit.
Bethesda, MarylandAges 18–75 - NCT05139017RecruitingPhase 2/Phase 3
Test drug Zilovertamab vedotin with standard care for lymphoma
This trial studies zilovertamab vedotin added to standard chemotherapy for people with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). It may help by targeting lymphoma cells and improving how well standard treatment works after prior treatments have failed.
Glendale, ArizonaAges 18 years+ - NCT05160584Recruiting
Real-world treatment study for relapsed or refractory myeloma
