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+ - 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 - NCT05067595RecruitingPhase 1
Fecal transplant and fiber for gut graft-versus-host disease
This study tests whether a fecal microbiota transplant (a procedure that puts healthy donor bacteria into your gut) combined with a dietary fiber supplement can help treat gut graft-versus-host disease, a common complication after a stem cell transplant. It may help reduce diarrhea and other gut symptoms.
Seattle, WashingtonAges 18 years+ - NCT05098613RecruitingPhase 1
Testing a new immune cell therapy for relapsed B-cell lymphoma
This trial is testing a new treatment called CD19x22 CAR T cells for people with certain types of B-cell lymphoma that have come back or not responded to other treatments. The therapy uses your own immune cells, which are modified in a lab to better attack the cancer.
Aurora, ColoradoAges 16 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+ - 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+ - NCT05110742RecruitingPhase 1/Phase 2
CD5-targeting NK cell therapy for blood cancers
This trial tests a new kind of immune cell therapy (NK cells) that are made to attack cancer cells carrying the CD5 marker. You will have a short course of chemotherapy before the infusion to help the cells work. It is for people with certain blood cancers that have not responded to standard treatments.
Houston, TexasAges 18 years+ - NCT05135351Recruiting
Prebiotics to help your gut health after cancer cell treatment
This trial tests whether taking prebiotics (food for helpful gut bacteria) can improve gut microbiome diversity after your own cancer-cell treatment, like autologous stem cell transplant or CAR-T. It may help your gut ecosystem recover during and after therapy.
Omaha, NebraskaAges 19 years+ - NCT05082519RecruitingPhase 2
Calorie restriction and exercise to improve leukemia treatment in young patients
This study tests whether a special diet (calorie restriction) and increased physical activity can make chemotherapy work better for young people with B-ALL. Participants will follow a monitored diet and exercise plan during their first month of treatment.
Los Angeles, CaliforniaAges 7–25 - NCT05130138Recruiting
Medication review for drug interactions in chronic myeloid leukemia
This study looks at how your current leukemia medicines and herbal or plant-based products may interact, and how that could affect outcomes in chronic myeloid leukemia. It may help doctors better understand which drug combinations are safest and most effective.
Saint-EtienneAges 18 years+ - 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+ - NCT05092451RecruitingPhase 1/Phase 2
CD70-targeting NK cell therapy for blood cancer relapse
This study tests an immune therapy made from cord blood “NK cells” that are engineered to attack cells with a marker called CD70. It’s given after chemotherapy that reduces your blood and immune system, aiming to treat relapse or refractory (not responding) blood cancers.
