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+ - NCT05674175RecruitingPhase 1/Phase 2
Test two engineered immune cell treatments for B-cell leukemia
This trial tests a combination of two different engineered immune cell therapies to treat B-ALL (a leukemia). It’s designed for young people whose disease has come back, is hard to treat, or didn’t respond well to similar cell therapies.
Philadelphia, PennsylvaniaAges Up to 29 years - NCT05657652Recruiting
Medicine regimen for relapsed or refractory B-ALL
This trial studies a specific treatment plan (“CAV regimen”) for people with B-cell ALL that has either come back or did not respond to standard treatment. It may help control the leukemia, if you meet the health and safety requirements.
Suzhou, JiangsuAges 15–70 - NCT05657639RecruitingPhase 2
Study treatment for relapsed or hard-to-treat AML
This Phase 2 trial tests a new combination treatment (the “CAV regimen”) for people with relapsed or refractory acute myeloid leukemia (AML). It may help your body control leukemia again, especially if prior standard intensive treatments were not enough or the leukemia came back.
Suzhou, JiangsuAges 16–70 - NCT05480449RecruitingPhase 1/Phase 2
Personalized CAR-T for children with high-risk B-ALL
This trial studies a personalized type of immune therapy (CAR-T) made from your own cells to treat pediatric B-ALL that has returned or not responded to prior treatment. It aims to see how well this manufactured CAR-T works and how safely it can be given.
Philadelphia, PennsylvaniaAges birth–29 years - NCT05442216RecruitingPhase 2
Study of tagraxofusp, azacitidine, and venetoclax for secondary AML
This trial tests a combination of three drugs (tagraxofusp, azacitidine, and venetoclax) for people newly diagnosed with a type of acute myeloid leukemia (AML) that has developed after treatment with certain prior drugs (hypomethylating agents). The goal is to see if this combination is safe and effective.
Miami, FloridaAges 18 years+ - NCT05444348Recruiting
Communication and care-planning support for blood cancer patients
This study tests an approach to help people with certain blood cancers and their main caregiver plan ahead and communicate more clearly about end-of-life care. It may help patients feel more supported and better prepared for difficult decisions.
AalborgAges 18 years+ - NCT05101551RecruitingPhase 1
Talazoparib with chemotherapy for relapsed childhood AML
This Phase 1 study tests whether talazoparib combined with chemotherapy is safe and potentially effective for children and young adults whose leukemia has come back or did not respond. It focuses on finding the best way to give the treatment and watching for side effects.
Phoenix, ArizonaAges Up to 21 years - NCT04544592RecruitingPhase 1/Phase 2
CD19 CAR-T for children and young adults with B-cell blood cancers
This trial tests a one-time, lab-made immune cell treatment (CD19 CAR-T) for certain B-cell blood cancers in children and young adults. It may help people whose leukemia or lymphoma is not responding to standard treatment or has come back.
Aurora, ColoradoAges 1 month–30 years - NCT04318678RecruitingPhase 1
CD123 CAR T-cell therapy for relapsed leukemia and related cancers
This early-phase study tests a lab-made immune therapy (CD123 CAR T cells) for children and young adults up to age 21 whose cancer has come back or didn’t respond to treatment. The goal is to see if these CAR T cells can find and attack cancer cells that carry a marker called CD123.
Memphis, TennesseeAges Up to 21 years - NCT04068597RecruitingPhase 1/Phase 2
Testing inobrodib for blood cancers that came back
This is an early-stage study of inobrodib (CCS1477) for blood cancers like lymphoma, multiple myeloma, or acute myeloid leukemia that have returned or did not respond to standard treatment. It aims to see whether the drug is safe and can help control the cancer.
Atlanta, GeorgiaAges 18 years+ - NCT06961669Recruiting
CD19 CAR-T cells for B-cell cancers and multiple myeloma
This trial tests a personalized treatment where your own immune cells are modified to target and kill cancer cells that have a protein called CD19. It is for patients with certain types of B-cell lymphoma, B-cell acute leukemia, or multiple myeloma that has come back or not responded to previous treatment.
HefeiAges 3 years+ - NCT06088888RecruitingPhase 1
TGRX-678 for CML that hasn't responded to other treatments
This study tests a new daily pill called TGRX-678 for people with chronic-phase CML who have not responded well to or cannot tolerate other CML treatments. It aims to see if the drug is safe and if it can help control the leukemia.
Houston, TexasAges 18 years+ - NCT06678282Recruiting
Testing an investigational cell therapy for B-cell lymphoma or leukemia
This trial tests a new cell therapy (JY231) for people with B-cell lymphoma or B-cell acute lymphoblastic leukemia (B-ALL) that has come back or didn't respond to previous treatments. The therapy targets a marker on cancer cells called CD19 and aims to help your body fight the cancer.
Zhenzhou, HenanAges 18–75 - NCT06307600RecruitingEarly Phase 1
CAR T-Cell Therapy for Relapsed or Refractory B-ALL
This trial tests a new CAR T-cell therapy (called RD06-03) for people whose B-cell acute lymphoblastic leukemia (B-ALL) has returned or hasn't responded to other treatments. It aims to see if the therapy is safe and can help fight the leukemia.
Hefei, AnhuiAges 3–70 - NCT06689917Recruiting
JY231 injection for relapsed B-cell lymphoma or leukemia
This trial tests a new cell therapy called JY231 for people whose B-cell lymphoma or leukemia has come back or not responded to standard treatments. The therapy targets a protein on cancer cells called CD19 and may help your immune system fight the cancer.
Wuhan, HubeiAges 18–75 - NCT06810778RecruitingPhase 1/Phase 2
Duvelisib plus venetoclax for relapsed PTCL
This study tests two oral drugs—duvelisib and venetoclax—to see if together they can help people with a type of lymphoma called peripheral T-cell lymphoma (PTCL) that has not responded to at least two prior treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT03459534RecruitingPhase 3
Radotinib for CML patients after prior TKI failure
This trial tests radotinib (a targeted pill) in people with chronic-phase Philadelphia chromosome–positive CML whose previous TKIs stopped working or could not be tolerated. It aims to improve control of the leukemia while checking safety.

Common questions
- Are there clinical trials for refractory acute leukemia?
- Yes. Clin2 currently lists 378 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.
