Los Angeles, CaliforniaAges birth–21 years - NCT06343090Recruiting
Comparing two CAR T cell treatments for children and adults with B-ALL
This trial tests whether giving two types of CAR T cells (CD19 and CD22) one after the other works better than giving just one type (CD19) followed by a stem cell transplant for people whose B-cell acute lymphoblastic leukemia (B-ALL) has come back or not gone away. The goal is to see which approach offers a better chance of long-term remission.
Beijing, Beijing MunicipalityAges 1–70 - 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 - NCT06316427RecruitingPhase 1/Phase 2
CD7 CAR-T therapy for T-cell cancers that returned
This trial tests a new kind of immunotherapy called CD7 CAR-T therapy for people with T-cell cancers (like leukemia or lymphoma) that have come back or not responded to treatment.

Los Angeles, CaliforniaAges birth–18 years - NCT06137118RecruitingPhase 1/Phase 2
Study of AZD0486 for relapsed or refractory B-cell ALL
This trial tests a new investigational drug (AZD0486) given alone to see if it is safe and effective for people with B-cell acute lymphoblastic leukemia (ALL) that has come back or hasn't responded to treatment. It specifically targets a protein called CD19 found on leukemia cells.
Birmingham, AlabamaAges 12 years+ - NCT02508038RecruitingPhase 1
Test CD19+ depleted donor transplant for hard childhood cancers
This Phase 1 study tests a special type of half-matched (haploidentical) stem cell transplant plus medicines, aiming to reduce cancer relapse after transplant. It may help children and teens with certain leukemia/lymphoma or specific solid tumors who do not have a fully matched donor or whose best options are limited.
Madison, WisconsinAges 7 months–21 years - NCT03595917RecruitingPhase 1
New and hard-to-treat BCR-ABL leukemia drugs plus prednisone and blinatumomab
This Phase 1 study tests a combination of targeted cancer drugs with prednisone and blinatumomab in people with BCR-ABL–positive B-cell leukemia (B-ALL), or chronic myeloid leukemia (CML) in lymphoid blast crisis. It may help by attacking leukemia cells through multiple pathways, especially when standard intensive chemotherapy is not suitable.
Chicago, IllinoisAges 18 years+ - NCT04260022RecruitingPhase 1
Drug study for hard-to-treat CML or Ph+ ALL
This Phase 1 study tests HQP1351 for people with CML or Ph+ ALL that has not responded well to standard targeted pills (TKIs), or those who could not tolerate them. It’s designed to see whether the treatment can work and how safe it is for this difficult-to-treat group.
Birmingham, AlabamaAges 18 years+ - NCT06013423RecruitingPhase 2
Cord blood transplant with chemo and radiation for high-risk blood cancers
This trial tests a cord blood transplant after a reduced-intensity chemotherapy and radiation regimen for patients with high-risk blood cancers like leukemia, lymphoma, or MDS. The goal is to see if this approach can help destroy cancer cells and restore healthy blood cells.
Seattle, WashingtonAges 6 months–65 years - NCT05857969RecruitingPhase 1
Testing cancer drug response on removed tumor tissue
This early study uses tumor tissue (or bone marrow from blood cancers) and performs lab tests to see which cancer drugs may work better for each person. It also collects genetic information from blood or a saliva swab to help understand why cancers respond differently.
Miami, FloridaAges 1 day–21 years - NCT05800210RecruitingPhase 2
T cell and B cell immune “wipeout” after stem cell transplant
This Phase 2 trial studies whether removing certain immune cells (alpha/beta T cells and CD19+ B cells) around the time of a stem cell transplant can improve outcomes for people with high-risk blood cancers. It may help by reducing the immune responses that can interfere with the transplant working, while keeping the process safe.
Gainesville, FloridaAges 6 months–39 years - 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 - NCT05735717RecruitingPhase 2
T-cell transplant using depleted receptors for blood cancers
This Phase 2 study tests a specialized stem cell transplant that removes certain immune “T-cell” receptors to help treat blood cancers like acute leukemia. It may help your body rebuild a healthier immune system after high-dose treatment.
