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 - NCT05054257RecruitingPhase 1
CAR T19 for hard-to-treat blood cancers that have CD19
This Phase 1 study tests CAR T cells designed to attack cancer cells that carry a marker called CD19. It’s for adults with certain relapsed or treatment-resistant B-cell leukemias (ALL) or lymphomas (NHL) where other treatments may not have worked.
PragueAges 18–80 - 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 - NCT05190471RecruitingPhase 1
Study drug for adults with AML that did not respond or returned
This Phase 1 study tests BP1002 in adults with acute myeloid leukemia (AML) that is refractory (not responding) or relapsed (coming back). It’s early-stage, aiming to find a safe dose and see if the treatment can help people with limited options.
La Jolla, CaliforniaAges 18 years+ - NCT05211570RecruitingPhase 1/Phase 2
Study drug AB8939 for AML after prior treatments
This Phase 1/2 study tests AB8939 in people with acute myeloid leukemia (AML) whose disease has come back or did not respond to earlier treatment. It may help researchers find a safe dose and learn whether the treatment can control the leukemia.
Houston, TexasAges 18 years+ - NCT05237258Recruiting
Compare palliative care approaches for people with high-risk AML
This study tests a specialized (targeted) palliative care program versus usual oncology care for people hospitalized with high-risk acute myeloid leukemia (AML). The goal is to see if this palliative approach improves comfort, support, and care planning during intensive treatment.
