Houston, TexasAges 21 years+ - NCT05062707Recruiting
Study of early aging in young people during cancer treatment
This study looks at how “early aging” changes show up during treatment in young adults with cancer. It may help doctors better understand health effects during curative therapy and improve care for people your age.
GroningenAges 18–39 - NCT05064176Recruiting
Reconstructive lymph surgery plus usual care for lymphoedema
This study tests whether adding a reconstructive lymph surgery to standard lymphoedema care improves symptoms and function. It may help people with moderate lymphoedema who have already tried therapy for several months.
GhentAges 18 years+ - NCT05066412RecruitingPhase 1
Preventing relapse after a half-matched transplant with modified donor cells
This early-phase study tests whether giving donor immune cells (DLI) that have been “depleted” of a specific marker (CD45RA) can lower the chance of the leukemia/lymphoma coming back after a half-matched stem cell transplant. It’s meant to be preventive, not treatment for an active relapse.
Geneva, Canton of GenevaAges 18 years+ - NCT05070845RecruitingPhase 2
Study drug for immune thrombocytopenia with low platelets
This Phase 2 study tests how safe and effective PF-06835375 is for people with primary immune thrombocytopenia (ITP), a condition where platelet counts are too low. It may help reduce bleeding risk by improving platelet levels, depending on the results.
Greenville, North CarolinaAges 18–70 - NCT05074355RecruitingPhase 2
Venetoclax plus azacitidine for advanced MPN without BCR-ABL
This trial tests whether venetoclax together with azacitidine can shrink and control advanced blood cancers caused by myeloproliferative neoplasms (MPN) that do not have the BCR-ABL gene. It may help people whose disease has moved into an accelerated or blast phase when standard options haven’t yet included blast-reducing treatment.
Toronto, OntarioAges 18 years+ - NCT05079282RecruitingPhase 1
Study drug for relapsed or treatment-resistant T-cell lymphoma
This early-phase (Phase 1) study tests ONO-4685 in adults whose T-cell lymphoma has come back or did not respond to treatment. It aims to find a safe dose and see whether it can shrink lymphoma in people with limited options.
Birmingham, AlabamaAges 18 years+ - NCT05089227RecruitingPhase 2
Long-term apixaban to prevent clots in autoimmune hemolytic anemia
This Phase 2 trial tests whether taking long-term apixaban (a blood thinner) can prevent venous blood clots in people with autoimmune hemolytic anemia (AIHA). It may help reduce the risk of dangerous clotting events if you meet safety and risk criteria.
DijonAges 18 years+ - NCT05091372RecruitingPhase 2
Maintenance treatment after transplant for newly diagnosed myeloma
This trial tests whether using belantamab mafodotin plus lenalidomide as long-term maintenance after an autologous stem cell transplant can keep multiple myeloma under control, guided by minimal residual disease (MRD). MRD is a very small amount of disease that may remain after transplant, and the study helps see if treating those patients better improves outcomes.
Houston, TexasAges 18 years+ - NCT05093153Recruiting
Registry for adults with IgM blood protein conditions
This study is a registry that collects information about adults with certain IgM-related blood conditions. It may help doctors better understand these illnesses and improve future care.
Mérida, BadajozAges 18 years+ - NCT05093335RecruitingEarly Phase 1
PET scan test for CXCR4 in many relapsed cancers
This early study tests a new PET scan tracer (a radioactive imaging agent) that may light up a cell marker called CXCR4 in certain blood and solid tumor cancers. It may help doctors see where cancers are and how much CXCR4 they have, which could guide future treatments.
New York, New YorkAges 18 years+ - NCT05099874Recruiting
Computer training to improve attention in sickle cell disease
This trial tests whether a computer-based “attention control” training program can improve attention and daily functioning in children with sickle cell disease. To join, you must meet certain criteria and also pass an initial attention screening test during the study.
Washington D.C., District of ColumbiaAges 8–16 - NCT05099471RecruitingPhase 2
Venetoclax plus rituximab for Waldenström’s macroglobulinemia
This Phase 2 study tests whether the combination of venetoclax and rituximab works better for Waldenström’s macroglobulinemia (WM) than expected from standard approaches. It is for adults with WM who have symptoms or organ/health problems caused by the disease.
BielefeldAges 18 years+ - NCT05100056Recruiting
Brentuximab for adults with Hodgkin’s lymphoma after stem cell plans
This study looks at how well brentuximab vedotin works for adults with Hodgkin’s lymphoma who have either already had, or are being considered for, stem cell transplant. It may help people who are receiving a specific treatment plan to control the lymphoma after transplant planning.
Wroclaw, DolnoslskieAges 18 years+ - NCT05101551RecruitingPhase 1
Talazoparib with chemotherapy for relapsed childhood AML
This Phase 1 study tests whether talazoparib combined with chemotherapy is safe and potentially effective for children and young adults whose leukemia has come back or did not respond. It focuses on finding the best way to give the treatment and watching for side effects.
Phoenix, ArizonaAges Up to 21 years - NCT05104736RecruitingPhase 2
PT-112 for thymus gland tumors after prior chemotherapy
This trial studies PT-112, a new treatment, in people with thymoma or thymic carcinoma that has grown despite at least one prior platinum chemotherapy treatment. It may help shrink tumors or slow disease progression, especially when surgery is not possible.
Bethesda, MarylandAges 18–120 - NCT05105152RecruitingPhase 1
CAR T cell therapy for kids with CD33 AML that came back
This Phase 1 study tests a type of lab-made immune cell therapy (CAR T cells) made from your T cells to treat AML that has relapsed or not responded, as long as the cancer shows a marker called CD33. The goal is to see if the treatment is safe and can help control AML after it returns or resists standard therapy.
Seattle, WashingtonAges Up to 30 years - NCT05107674RecruitingPhase 1
Early drug study for advanced cancers that have limited options
This Phase 1 study tests NX-1607 in adults with advanced cancers that are hard to treat with standard care. It focuses on safety and early signs of how well the drug may work in specific cancer types.
Duarte, CaliforniaAges 18 years+ - NCT05108519Recruiting
Study of side effects and response to anti-VEGF treatments
This study looks at the side effects (complications) and how well people respond when they receive anti-VEGF cancer medicines. It may help doctors better manage treatment and understand who benefits most.
Houston, TexasAges Any age - NCT05112614Recruiting
Study links gut bacteria to cancer treatment response
This study looks at how the bacteria in your gut change during cancer treatment (and during some blood stem cell transplants). It may help researchers understand why some people respond differently and guide better future treatment.
Scottsdale, ArizonaAges 18–99 - NCT05123365RecruitingPhase 1/Phase 2
Testing a dose of N-acetylcysteine for certain blood cancers
This Phase 1/2 study tests what dose of N-acetylcysteine (NAC) is safe and potentially helpful for people with essential thrombocythemia, polycythemia vera, or myelofibrosis. It focuses on people who still have symptoms and meet blood and health requirements so researchers can monitor side effects and symptom changes.
Irvine, CaliforniaAges 18 years+ - NCT05124288Recruiting
Study immune changes after AML relapse after bone marrow transplant
This study looks at how the immune system changes when acute myeloid leukemia (AML) comes back after a donor stem cell transplant. It may help researchers create more personalized treatment plans and future guidelines for how to care for people in this situation.
Milan, MilanoAges 18 years+ - NCT05126849RecruitingPhase 2
Stem cell transplant using half-matched donor and cyclophosphamide
This trial tests a stem cell transplant option for children or young adults with severe aplastic anemia that did not respond to prior immune-suppressing treatment. It uses a “half-matched” donor and gives post-transplant cyclophosphamide to help the donor cells work and reduce certain immune reactions.
