Recruiting studies
- NCT04678401RecruitingPhase 1
Trial tests transplant using a half-matched donor for high-risk leukemia
This Phase 1 trial tests a special bone marrow transplant using a related “half-matched” donor (haploidentical), without a specific immune-suppressing medicine (“IS-free”). It’s for adults with certain high-risk AML or MDS to see if this approach can improve control of the disease while tracking safety.
Boston, MassachusettsAges 18–75 - NCT06326008RecruitingPhase 1
Donor immune cell therapy for leukemia that returned after treatment
This trial tests a two-step approach using donor immune cells to treat children with B-cell acute lymphoblastic leukemia (B-ALL) that has come back or not responded to standard treatments. First, a donor's CD19-targeted cells are given to bridge to a stem cell transplant, followed by CD22-targeted cells to prevent relapse.
Beijing, Beijing MunicipalityAges 1–18 - NCT06532084RecruitingPhase 2
Sorafenib to prevent relapse after stem cell transplant
This trial tests whether the drug sorafenib can prevent blood cancer from returning after a stem cell transplant. It is for people who had a special combination of chemotherapy (bendamustine and cyclophosphamide) during their transplant and are at high risk for relapse.
Saint PetersburgAges 18–75 - NCT07374029RecruitingPhase 1
T cell therapy with vaccine, decitabine, and venetoclax in AML
This trial tests a treatment that combines a personalized vaccine made from your leukemia cells and your own immune cells (T cells) with standard chemotherapy drugs (decitabine and venetoclax). The goal is to help your immune system better fight the leukemia.
Boston, MassachusettsAges Any age - NCT05334823RecruitingPhase 2
CAR T-cell treatment for CD19-positive relapsed leukemia in children
This Phase 2 trial tests pCAR-19B, a customized immune-cell treatment for children and teens with CD19-positive B-ALL that has come back or did not respond to standard therapy. If eligible, you would receive the cell infusion after cell collection and testing to make sure the leukemia cells have the right marker.
Beijing, Beijing MunicipalityAges 3–21 - NCT05735184RecruitingPhase 1
Ziftomenib with AML medicines for NPM1- or KMT2A-mutated leukemia
This Phase 1 trial tests how safe and tolerable ziftomenib is when combined with standard AML medicines (like venetoclax and azacitidine, and other chemo options) in people with AML. It’s for AML patients who have specific genetic changes (NPM1 mutation or KMT2A rearrangement) and helps doctors find the best, safest dose plan.
Phoenix, ArizonaAges 18 years+ - NCT04603872RecruitingEarly Phase 1
CAR-T plus dasatinib for hard-to-treat B-cell cancers
This early study tests a cancer-fighting treatment that uses CAR-T cells together with dasatinib for people whose B-cell cancers have come back or did not respond. It aims to improve control of the cancer in cases that are often resistant to standard treatment.
Hangzhou, ZhejiangAges 18–70 - 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.
Birmingham, AlabamaAges 18–120 - NCT06928662RecruitingPhase 1/Phase 2
Chemo, radiation, and donor stem cell transplant for high-risk blood cancers
This trial tests a strong chemotherapy and radiation combo followed by a donor stem cell transplant for people with aggressive blood cancers (like AML or MDS) that haven't responded to earlier treatments or came back. It aims to help prevent the cancer from returning.

Safety study of MT-401-OTS for relapsed AML or MDS
This trial tests a new cell therapy called MT-401-OTS for people aged 65 or older with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) that has come back or not responded to treatment. The goal is to see if this treatment is safe and to find the right dose.
Duarte, CaliforniaAges 65 years+ - NCT06834529RecruitingPhase 1/Phase 2
CAR-T cell therapy for returning B-cell leukemia or lymphoma
This trial tests a new type of immune cell therapy (CAR-T cells) designed to target and destroy leukemia or lymphoma cells that carry the CD19 or CD22 marker. It is for people whose cancer has not responded to other treatments or has returned.
Beijing, Beijing MunicipalityAges 14–75 - NCT07320235RecruitingPhase 1
Combination treatment for relapsed AML
This trial tests a new combination of drugs for people whose acute myeloid leukemia (AML) has come back or not responded after at least one prior treatment, and who have no other standard options. The goal is to see if adding imetelstat to other therapies can help.
New York, New YorkAges 18 years+ - NCT05658640RecruitingPhase 1/Phase 2
Testing trametinib and steroid plus chemo for relapsed blood cancers
This early-phase trial tests whether adding trametinib and dexamethasone to standard chemotherapy can improve outcomes for children whose blood cancer has come back or did not respond. Because it is a Phase 1/2 study, the main goal is to see safety and learn the best way to treat your specific cancer type.
ViennaAges 1–21 - NCT05745714RecruitingPhase 1/Phase 2
Targeted triple-combination treatment for children with relapsed blood cancers
This Phase 1/2 study tests a multi-drug combination (ruxolitinib, venetoclax, dexamethasone, plus chemotherapy) for children whose blood cancer has come back or did not respond. It aims to reduce the cancer by targeting specific genetic changes and may offer a new option when standard treatments have not worked.
ViennaAges 1–21 - NCT05805605RecruitingPhase 2
Low-intensity stem cell transplant with donor cells and blood-protection
This Phase 2 study tests a low-intensity bone marrow/stem cell transplant using a matched donor plus two medicines to help prevent the donor cells from attacking you. It aims to treat certain blood cancers—especially when standard treatment has not fully worked or when you are in remission but at higher risk.
Minneapolis, MinnesotaAges Up to 75 years - NCT07256210RecruitingPhase 2
Donor NK cells to prevent leukemia return after stem cell transplant
This trial tests whether giving donor natural killer (NK) cells after a stem cell transplant can help prevent leukemia from coming back. It is for people aged 14-25 with certain hard-to-treat leukemias who are already getting a stem cell transplant from a related donor.
