CAR-T cell therapy for relapsed B-cell blood cancers
This trial tests a special type of immune therapy called CD19-BAFF CAR-T cells for people whose B-cell acute lymphoblastic leukemia or B-cell non-Hodgkin lymphoma has come back or not responded to standard treatment. The therapy uses your own modified immune cells to target and kill cancer cells.

Walking and balance tests for people with hemophilia
This study checks if two simple walking and balance tests are reliable for people with hemophilia who have had joint bleeds. It may help doctors better track joint health and function.
VanAges 18–65 - NCT07851363Recruiting
Spinal fluid test for tracking brain lymphoma
This study uses a simple spinal fluid test (liquid biopsy) to find and track how primary CNS lymphoma responds to treatment. The goal is to help doctors plan your care with fewer invasive procedures.
Beijing, Beijing MunicipalityAges 18–75 - NCT07851493Recruiting
Exercise assessment before chemotherapy for multiple myeloma
This study looks at how exercise affects the body before you start chemotherapy for multiple myeloma. It aims to understand your fitness level to help tailor treatment support.
Munich, BavariaAges 18–99 - NCT06299553Recruiting
Study of tafasitamab with lenalidomide for relapsed DLBCL patients
This study looks at how well a combination of two drugs, tafasitamab and lenalidomide, works for people with a type of lymphoma (DLBCL) that has come back or hasn't responded to treatment. After the combination, patients continue with tafasitamab alone. This is for patients who cannot have a stem cell transplant.
MilanAges 18 years+ - NCT05326919Recruiting
Study biobank for people newly diagnosed with certain blood cancers
This study follows people who are newly diagnosed (and haven’t been fully treated yet) with specific leukemia or related blood disorders to help researchers learn which treatments may work best. It may help by connecting you to a larger “precision medicine” patient group for future research.
BobignyAges Any age - NCT05580861RecruitingPhase 1/Phase 2
Sulfasalazine for newly diagnosed AML in older adults on chemo
This Phase 1/2 trial studies whether sulfasalazine, added to intensive chemotherapy, can help older adults with newly diagnosed acute myeloid leukemia (AML). It aims to improve treatment effectiveness and track leukemia “leftover cells” in some participants.
AmiensAges 60 years+ - NCT05310591RecruitingPhase 1/Phase 2
Study anti-PD1 treatment with Kymriah re-dosing for leukemia
This Phase 1/2 trial studies giving an anti-PD1 antibody (like pembrolizumab or nivolumab) along with a second Kymriah (tisagenlecleucel) infusion in children and young adults whose B-cell leukemia is coming back or their Kymriah effect has faded. It may help the new immune treatment work better after the first Kymriah.
BordeauxAges 1–25 - NCT04905810RecruitingPhase 2
Azacitidine or decitabine plus venetoclax for AML after prior failure
This trial studies whether adding venetoclax to either azacitidine or decitabine can treat acute myeloid leukemia (AML) when earlier “hypomethylating” treatment has stopped working. You might be a candidate if you’ve already tried azacitidine or decitabine for a related blood condition and it failed, and you meet the health-safety limits.
