Recruiting studies
- NCT05798897RecruitingPhase 1
Study drug MT-601 for relapsed lymphoma patients
This early-phase trial tests MT-601 (an experimental treatment) in adults whose lymphoma has come back or didn’t respond to standard treatments. The study mainly checks safety, and it also looks for early signs that the treatment can shrink tumors.
Duarte, CaliforniaAges 18–100 - NCT05734066RecruitingPhase 1/Phase 2
Lurbinectedin drug study for young people with Ewing sarcoma
This trial tests lurbinectedin, a cancer medicine, by itself (no other drugs) in children and young adults whose Ewing sarcoma has come back or did not respond to prior treatment. It aims to see how safe the drug is and whether it can help control the cancer.
Los Angeles, CaliforniaAges 2–30 - NCT05732103RecruitingPhase 1/Phase 2
Testing CTX-712 for AML or high-risk MDS after prior treatment
This early-phase study tests CTX-712, a new cancer treatment, in people whose acute myeloid leukemia (AML) or certain high-risk blood cancers came back or did not respond to prior therapy. It may help shrink the cancer and control the disease by targeting it differently than standard treatments.
Phoenix, ArizonaAges 18 years+ - NCT05730036RecruitingPhase 3
Linvoseltamab vs standard treatment for relapsed myeloma
This trial compares linvoseltamab against a standard combination (elotuzumab + pomalidomide + dexamethasone) in adults with multiple myeloma that has returned or not responded. It aims to find out whether linvoseltamab works better and is safe for people who have already had some myeloma treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT05681195RecruitingPhase 2
Zanubrutinib plus pemetrexed for recurrent brain lymphomas
This trial tests zanubrutinib (a targeted lymphoma medicine) together with pemetrexed (chemotherapy) for lymphoma that has come back or did not respond well in or around the brain. It may help shrink measurable lymphoma and improve control of disease after prior treatments.
Miami, FloridaAges 18 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.

Phase 1 test of a CD19/CD20 therapy for lymphoma
This Phase 1 study tests an investigational treatment for adults with lymphoma that has come back or did not respond to prior treatments. It targets lymphoma cells that have CD19 and CD20 markers, aiming to reduce or control the disease in people with limited options.
Newport Beach, CaliforniaAges 18 years+ - NCT05597306RecruitingPhase 1
Venetoclax plus bomedemstat for relapsed or hard-to-treat AML
This early-phase study tests venetoclax together with bomedemstat in adults whose acute myeloid leukemia (AML) has come back or did not respond to standard treatment. The goal is to see whether this combination can control the leukemia safely and help shrink it enough to improve outcomes.
Miami, FloridaAges 18 years+ - NCT05533775RecruitingPhase 1/Phase 2
Study of an antibody medicine with or without chemotherapy for relapsed lymphoma
This trial tests glofitamab alone or with chemotherapy and immunotherapy in children and young adults whose “mature B-cell” non-Hodgkin lymphoma has come back or hasn’t responded to treatment. It looks at whether the study medicines can shrink lymphoma again and are safe enough to use in this age group.
Birmingham, AlabamaAges 6 months–30 years - NCT05530421RecruitingPhase 2
Selinexor and Venetoclax with Dexamethasone for Myeloma
This trial studies a combination of selinexor, venetoclax, and dexamethasone to treat multiple myeloma that has returned or is resistant to prior treatments. It may help shrink the myeloma and improve disease control in people with a specific myeloma genetic marker (t(11;14)).
Coral Gables, FloridaAges 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+ - NCT05521984RecruitingPhase 1
Dapagliflozin trial for children with hard-to-treat brain tumors
This Phase 1 trial tests whether dapagliflozin (an SGLT2 medicine) can help shrink or control certain pediatric brain tumors or other solid tumors that have come back or won’t respond. It’s designed mainly to check safety and early signs of effect in children and young adults who have limited treatment options.
St Louis, MissouriAges 6–21 - NCT05463263RecruitingPhase 1/Phase 2
Study drug for adults with relapsed or treatment-resistant lymphomas
This Phase 1/2 study tests dencatistat (STP938) to treat adults whose B-cell or T-cell lymphoma has come back or not responded to treatment. It looks at safety, the best dose, and whether it can shrink tumors or improve disease control when standard options have not helped.

Olverembatinib plus APG-2575 for children with resistant leukemia
This study tests a new combination of two oral drugs (olverembatinib and APG-2575) for children with a type of leukemia (Ph+ ALL) that has returned or stopped responding to standard treatments. The goal is to see if this combination is safe and effective.

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.

Study brain and thinking effects after CAR T therapy in youth
This study looks at how CAR T-cell treatment affects thinking, learning, and day-to-day brain function in children and young adults with certain blood cancers. You (and a caregiver) may complete online testing so researchers can track these changes over time and whether support is needed.
Los Angeles, CaliforniaAges 5 years+ - NCT05180097RecruitingPhase 2
Immunotherapy with stem cell transplant for relapsed Hodgkin lymphoma
This Phase 2 trial tests whether pembrolizumab plus brentuximab works better than standard chemotherapy followed by an autologous stem cell transplant for people whose classic Hodgkin lymphoma has come back or did not respond. It may help by improving cancer control before and around stem cell transplant and by comparing outcomes between the two treatment approaches.
