Enasidenib plus azacitidine for IDH2-mutated AML
This trial studies the combination of enasidenib and azacitidine in people with acute myeloid leukemia (AML) that has an IDH2 gene mutation. It may help control the leukemia when prior treatments didn’t work or the disease came back.
Houston, TexasAges 18 years+ - NCT03826992RecruitingPhase 1
Study drug Venetoclax plus Vyxeos for hard-to-treat leukemia
This Phase 1 study tests whether a combination of venetoclax and Vyxeos can treat children and young adults with certain relapsed or treatment-resistant acute leukemias. It may help shrink the leukemia or improve blood counts when standard treatments have not worked.
Cincinnati, OhioAges 1–39 - NCT03850574RecruitingPhase 1/Phase 2
Tuspetinib for relapsed or hard-to-treat AML
This early-phase study tests tuspetinib in people with AML that has come back or did not respond to treatment. The goal is to learn whether it is safe and tolerable, how the drug behaves in the body, and whether it shows signs of benefit.
Birmingham, AlabamaAges 18 years+ - NCT03970096RecruitingPhase 2
Reduce graft-versus-host disease after stem cell transplant
This Phase 2 study tests ways to lower the risk of graft-versus-host disease (GVHD), a serious complication after an allogeneic stem cell transplant from a matched donor. It is for people with acute leukemia or MDS who are going to receive intensive conditioning therapy, aiming to improve safety while keeping the transplant effective.
Tampa, FloridaAges 1–60 - NCT07133997RecruitingPhase 1
Combination therapy for relapsed CD19+ B-cell leukemia

Duarte, CaliforniaAges 12–55 - NCT04047641RecruitingPhase 1/Phase 2
Quizartinib with chemotherapy for new or returning leukemia
This trial tests a combination of anti-leukemia drugs (including quizartinib) together with chemotherapy for people with acute myeloid leukemia (AML), a rare mixed-type leukemia, or high-risk myelodysplastic syndrome (MDS). It may help by trying to better control cancer in people whose disease is newly diagnosed or has returned/not responded to prior treatment.
Houston, TexasAges 18 years+ - NCT04140487RecruitingPhase 1/Phase 2
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.
