Recruiting studies
- 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 - NCT07570173RecruitingPhase 2/Phase 3
MK-1045 for Hard-to-Treat B-Cell Leukemia
This trial tests a new drug called MK-1045 in patients whose acute lymphoblastic leukemia (a blood cancer) has come back or stopped responding to previous treatments. The goal is to see if this drug can help control the cancer when other options haven't worked.
Copenhagen, Capital RegionAges 12 years+ - NCT05143996RecruitingPhase 1
First study drug for relapsed AML or MDS
This Phase 1 trial tests CLN-049 in adults whose acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) has come back or did not respond to treatment. The goal is to find out how well the drug can work and how safe it is in people with limited options.
Birmingham, AlabamaAges 18 years+ - NCT07107126RecruitingPhase 1
Testing a new drug for relapsed AML or high-risk MDS
This trial tests a new drug called RPT1G for adults with acute myeloid leukemia or high-risk myelodysplastic syndromes that have not responded to standard treatments. The goal is to see if the drug is safe and if it shows signs of helping control the disease.
New York, New YorkAges 18 years+ - NCT06058858Recruiting
CMV reactivation after CAR-T cell therapy for leukemia or lymphoma
This study looks at how often a common virus called CMV reactivates—meaning it becomes active again—in patients who receive CAR-T cell treatment for leukemia or lymphoma. It aims to understand the risks and help doctors better manage care.
ParisAges 1–100 - NCT06533579RecruitingPhase 1/Phase 2
Gene therapy for CD19-positive blood cancers
This trial tests a new gene therapy treatment for people with certain types of leukemia or lymphoma that have the CD19 marker and have not responded to other treatments. The therapy uses a virus to deliver a gene to target and kill cancer cells.

Radioimmunotherapy then CD19 CAR T for hard-to-treat blood cancers
This early-phase study tests a two-step treatment: first a targeted radioactive antibody (131-I apamistamab) and then CD19 CAR T-cell therapy. It is for adults with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL) or diffuse large B-cell lymphoma (DLBCL) that is not responding or has come back, aiming to shrink cancer using engineered immune cells.
Basking Ridge, New JerseyAges 18 years+ - NCT07039877RecruitingPhase 2
Low-dose venetoclax with itraconazole and TACL for relapsed or refractory ALL
This trial tests a combination of low-dose venetoclax (a targeted cancer pill) plus itraconazole (an antifungal) and chemotherapy drugs for adults with acute lymphoblastic leukemia (ALL) that has come back or hasn't responded to first treatment.
Monterrey, Nuevo LeónAges 16–45 - NCT06408194RecruitingPhase 1
CD22 CAR T cells after Kymriah for B-cell cancers
This trial tests a new CAR T-cell therapy that targets CD22, after you've already received or been scheduled for a standard CD19-targeting CAR T-cell therapy (Kymriah). The goal is to see if giving a second type of CAR T cells can help when the first one doesn't work or the cancer returns.
Palo Alto, CaliforniaAges 1–25 - NCT07036250RecruitingPhase 1/Phase 2
Study of U32 for acute myeloid leukemia
This trial tests a new treatment called U32 for people with acute myeloid leukemia (AML) that has come back or not responded to prior therapy. It aims to see if targeting certain proteins on leukemia cells can help control the disease.
SuzhouAges 2–65 - NCT07405424Recruiting
Spiritual care support for adults with new acute leukemia
This study tests whether adding spiritual care to standard treatment helps adults newly diagnosed with acute leukemia feel better emotionally and spiritually. You may join if you are starting your first hospital treatment for AML or ALL.
Chicago, IllinoisAges 18 years+ - NCT04836507RecruitingPhase 1/Phase 2
Study of a lab-made cell therapy for lymphoma and leukemia
This Phase 1/2 trial tests CRC01, a lab-made immune cell therapy, for adults whose lymphoma or B-cell leukemia has come back or did not respond to treatment. If you qualify, the study aims to see how safe CRC01 is and whether it can shrink tumors and improve outcomes.
SeoulAges 19 years+ - NCT04167696RecruitingPhase 1
Dose-finding drug study for AML or MDS after standard options fail
This Phase 1 trial tests CYAD-02 to find the safest and recommended dose for people with AML or MDS that has returned or did not respond to prior treatment. It may help if you have limited treatment options, but participation also requires meeting specific heart, lung, and lab safety requirements.
Jacksonville, FloridaAges 18 years+ - NCT03113643RecruitingPhase 1
SL-401 with standard drugs for hard-to-treat blood cancers
This Phase 1 study tests SL-401, given with azacitidine and sometimes venetoclax, to treat acute myeloid leukemia (AML), high-risk myelodysplastic syndrome (MDS), or blastic plasmacytoid dendritic cell neoplasm (BPDCN). It aims to find a safe dose and see whether the combination can improve blood cancer control.
Duarte, CaliforniaAges 18 years+ - NCT06287229RecruitingPhase 1/Phase 2
CAR T therapy for B-cell ALL after initial treatment
This trial tests whether a special immune cell therapy (brexucabtagene autoleucel, or CAR T therapy) can help people with B-cell acute lymphocytic leukemia (ALL) after reducing the number of leukemia cells with a chemo-immunotherapy combination. It is for patients whose cancer has returned or is hard to treat, or for those newly diagnosed with a high-risk form of ALL.

Avapritinib for children with relapsed or resistant CBF-AML and KIT mutation
This trial tests a targeted drug called avapritinib in children and teens with a specific type of leukemia (CBF-AML) that has a KIT gene change and has come back or not responded to treatment. The goal is to see if avapritinib is safe and effective for these patients.
Hefei, AnhuiAges Up to 18 years - NCT05024552RecruitingPhase 1
Vyxeos plus gilteritinib for certain relapsed AML
This Phase 1 trial studies whether combining Vyxeos (a chemotherapy) with gilteritinib (a targeted drug) can treat AML that has come back or hasn’t responded well, specifically AML with certain FLT3 mutations. If it works, it could improve chances of controlling the leukemia.

Common questions
- Are there clinical trials for refractory acute leukemia?
- Yes. Clin2 currently lists 386 recruiting refractory acute leukemia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a refractory acute leukemia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a refractory acute leukemia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
