Study drugs for certain FLT3-mutated blood cancers that have returned
This trial tests a combination of three medicines—azacitidine, venetoclax, and gilteritinib—in people with specific gene changes (FLT3 mutations) in leukemia and related bone marrow diseases that have come back or are hard to treat. The goal is to see if this drug combination can control the disease and improve outcomes.
Houston, TexasAges 18 years+ - NCT04195633RecruitingPhase 2
Haploidentical donor stem cell transplant to treat blood cancers
This Phase 2 trial tests whether a specific stem cell transplant method (from a related “half-matched” donor) plus conditioning chemo and radiation can improve outcomes for several blood cancers. It may help people whose cancer is in remission but still considered high risk, or those who have had limited response after prior treatment.
Seattle, WashingtonAges 6 months+ - NCT04375631RecruitingPhase 1
Study of chemo plus donor stem cell transplant for blood cancers
This Phase 1 trial tests a specific chemotherapy plan followed by a reduced-intensity donor stem cell transplant for people with relapsed or treatment-resistant acute myeloid leukemia (AML), certain myelodysplastic syndromes (MDS), or chronic myelomonocytic leukemia (CMML). It may help by using donor stem cells to rebuild the bone marrow after intensive cancer treatment, in people who are not responding well to standard therapies.
Seattle, WashingtonAges 18 years+ - NCT04774393RecruitingPhase 1/Phase 2
Study for AML after it returns or resists treatment
This Phase 1/2 trial tests a combination of medicines (decitabine/cedazuridine, venetoclax, and ivosidenib or enasidenib) in people with acute myeloid leukemia (AML) that has come back or hasn’t responded. It may help control the leukemia by targeting cancer cells and specific genetic changes in the leukemia.
Houston, TexasAges 18 years+ - NCT04797767RecruitingPhase 1/Phase 2
Venetoclax plus CLAG-M for high-risk AML
This trial studies venetoclax combined with CLAG-M chemotherapy to treat adults with high-risk acute myeloid leukemia (AML) or related high-grade blood cancers. It aims to improve control of the disease, especially in people whose AML is considered high risk.
Seattle, WashingtonAges 18 years+ - NCT04892277RecruitingPhase 1
CD19 CAR-T for adults with hard-to-treat B-cell cancers
This Phase 1 trial tests a lab-made immune therapy (CD19 CAR-T) for adults whose B-cell cancers have come back or did not respond to treatment. It may help your immune system better recognize and attack cancer cells, but it is early research, so benefits and risks are still being defined.
Rochester, MinnesotaAges 18 years+ - NCT05418088RecruitingPhase 1
CAR T-cell therapy for hard-to-treat B-cell cancers
This Phase 1 study tests lab-made immune cells (CAR T-cells) that target CD19, CD20, and/or CD22 in people with certain relapsed or refractory B-cell cancers. It may help by attacking cancer cells that still carry these targets, but eligibility is very specific and includes prior treatments and health/lab requirements.
Columbus, OhioAges 2 years+ - NCT05672147RecruitingPhase 1
CD33 CAR T cells for hard-to-treat AML
This Phase 1 study tests a personalized immune-cell treatment (CD33 CAR T cells) for adults with AML that has returned or did not respond to treatment. It aims to see how safe the therapy is and how well it works for AML cells that carry the CD33 marker.
Duarte, CaliforniaAges 18 years+ - NCT05705570RecruitingPhase 1
CAR-T for CD19-positive relapsed or resistant blood cancers
