Recruiting studies
- NCT05679895RecruitingPhase 1
Study drug OC-1 for CD1a-positive T-ALL or T-LL after relapse
This Phase 1 trial tests the safety and early signs of benefit of OC-1 in people with relapsed or hard-to-treat T-cell leukemia/lymphoma (T-ALL/LL) that has a CD1a marker. You may be considered if standard treatments didn’t work or the cancer returned, and if your organs and infections are controlled.
BarcelonaAges 2 years+ - NCT05317403RecruitingPhase 1
Venetoclax plus chemo to change cancer cell behavior
This Phase 1 trial tests whether venetoclax, combined with chemotherapy and a “cancer cell behavior” medicine strategy, can improve treatment for people with AML that has come back or not gone into remission. It’s mainly looking at safety and early signs of benefit.
Milwaukee, WisconsinAges 1–25 - NCT04024761RecruitingPhase 1
NK cell therapy for leukemia relapse after transplant
This Phase 1 study tests whether an infusion of special immune cells (NK cells) from a donor can help control leukemia or related blood cancers that come back or do not fully go away after a stem cell transplant. It also uses short chemotherapy to “make space” for the NK cells to work, and IL-2 to help them function.
Boston, MassachusettsAges 12 years+ - NCT05432635RecruitingPhase 1
CAR T-cell and vaccine treatment after stem cell transplant
This Phase 1 study tests a customized immune-cell treatment (CAR T-cells) plus a vaccine given after stem cell transplant for certain aggressive B-cell non-Hodgkin lymphomas. It aims to help your immune system better recognize and attack the lymphoma and to see how safe the approach is.
Duarte, CaliforniaAges 18 years+ - NCT05544968RecruitingPhase 1
CD30-targeted cell treatment for hard-to-treat blood cancers
This Phase 1 trial studies an experimental treatment that targets a marker called CD30 on cancer cells. It is for adults with certain relapsed or refractory CD30-positive blood cancers to see how well the treatment works and what side effects it causes.
Milwaukee, WisconsinAges 18 years+ - NCT06994676RecruitingPhase 1
Study of CBX-250 for advanced myeloid leukemias
This study tests an experimental drug, CBX-250, for people with certain advanced blood cancers (like AML) that have not responded to standard treatments or have returned. The drug works only for people who have a specific genetic marker (HLA-A*02:01). The goal is to see if it is safe and how well it works.
Duarte, CaliforniaAges 12 years+ - NCT03630991RecruitingPhase 1
Calcium chelator medicine for AML or MDS during chemotherapy
This Phase 1 study tests whether edetate calcium disodium (also called succimer) can be safely given to people with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) while they are on chemotherapy. The goal is to learn the safest dose and whether it has signs of helping the blood cancer respond to treatment.
Houston, TexasAges 1 year+ - NCT05940272Recruiting

Combination drug therapy for relapsed or resistant large B-cell lymphoma
This trial tests a combination of three drugs (mosunetuzumab, polatuzumab vedotin, and lenalidomide) for people with diffuse large B-cell lymphoma (a type of blood cancer) that has come back or not responded to previous treatment. The goal is to see if this combination is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT07297173RecruitingPhase 1
Immune cell infusion plus transplant for tough leukemia
This trial tests a new two-step approach for people with hard-to-treat leukemia. First, you get chemotherapy plus an infusion of special immune cells from a partially matched donor, then a stem cell transplant. The goal is to see if this is safe and helps the leukemia go away.

Pembrolizumab and Ruxolitinib for Lymphoma
This trial is testing two drugs, pembrolizumab and ruxolitinib, together for people with certain types of lymphoma that have come back or not responded to at least one prior treatment. The goal is to see if this combination can help control the lymphoma.
New York, New YorkAges 18–95 - NCT04099966RecruitingPhase 2
Stem cell transplant to treat high-risk blood cancers
This trial tests a specialized donor stem cell transplant to treat high-risk problems in the blood and bone marrow, including some cancers and non-cancers. It may help by using donor immune cells designed to better control the disease after transplant.
Valhalla, New YorkAges 1 day–30 years - NCT05702853RecruitingPhase 1/Phase 2
CAR T-cell therapy after CD34 selection for CD19 lymphoma or CLL
This Phase 1/2 study tests a customized type of immune cell treatment (CD19 CAR T-cells) for people with certain relapsed or hard-to-treat lymphomas or CLL/SLL. It aims to improve control of disease by targeting the CD19 marker on cancer cells.

A study of ALETA-001 for certain B-cell blood cancers
This trial tests a new treatment called ALETA-001 for people with B-cell non-Hodgkin lymphoma that has come back or not responded to previous treatments, including CAR T-cell therapy. It aims to see if ALETA-001 can help when standard options have not worked.
