Recruiting studies
- 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 - 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+ - NCT05705570RecruitingPhase 1
CAR-T for CD19-positive relapsed or resistant blood cancers
This trial tests a type of immune treatment (CAR-T cells) for blood cancers that have come back or did not respond after standard treatments. It is for tumors that have CD19 on their cells, aiming to reduce the cancer and improve remission chances.
São Paulo, São PauloAges 2–70 - 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 - NCT05751044RecruitingPhase 1/Phase 2
Study of four medicines for children with difficult blood cancers
This Phase 1/2 trial tests a combination of medicines (dasatinib, venetoclax, dexamethasone, cyclophosphamide, and cytarabine) in children and teens whose blood cancer has come back or did not respond to treatment. It aims to see whether this approach can control the cancer while checking what doses are safe.
ViennaAges 1–21 - 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 - 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 - 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 - NCT06034561RecruitingPhase 2
Bortezomib for relapsed or refractory acute lymphoblastic leukemia
This trial tests a chemotherapy combination that includes bortezomib for people whose acute lymphoblastic leukemia (ALL) has come back or not responded to previous treatments. It aims to offer a new option for those who haven't tried bortezomib before.
São Paulo, São PauloAges 16–60 - NCT06081478RecruitingPhase 2
Targeted CAR-T cell therapy for advanced lymphoma or leukemia
This trial tests a new type of immune cell therapy (CAR-T) that targets two proteins on cancer cells—CD19 and CD22—to treat lymphoma or leukemia that has come back or not responded to standard treatment. It aims to see if this two-target approach works better.
Beijing, Beijing MunicipalityAges 14–85 - NCT06101381RecruitingPhase 1/Phase 2
Car-T cell therapy for relapsed or refractory leukemia and lymphoma
This trial tests whether a new immune therapy (CAR-T cells) can treat certain types of blood cancers that have come back or not responded to standard treatments. It aims to help people with aggressive B-cell lymphoma or acute lymphoblastic leukemia (ALL) that hasn't been controlled by other therapies.

AZD0486 for B-cell acute lymphoblastic leukemia
This trial tests a new drug called AZD0486 for people with a type of blood cancer called B-cell acute lymphoblastic leukemia (B-ALL) that has come back or not responded to treatment. It aims to see if the drug can help control the cancer.
Birmingham, AlabamaAges 12 years+ - NCT06173518RecruitingPhase 1
CAR T-cell therapy for children with B-cell leukemia or lymphoma

Philadelphia, PennsylvaniaAges birth–18 years - NCT06179524RecruitingPhase 2
CAR-T-19 for CD19-positive B-ALL in children and young adults
This trial tests a new type of immunotherapy called CAR-T-19 for children and young adults up to age 25 whose B-ALL has returned or is not responding to standard treatments. The CAR-T cells are engineered to find and destroy leukemia cells that have the CD19 protein.

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. The CAR-T cells are made from your own immune cells or a donor's, and they are designed to find and destroy cancer cells that carry the CD7 marker.
Beijing, Beijing MunicipalityAges 1–70 - NCT06316856RecruitingPhase 1/Phase 2
Targeted immune cell therapy for resistant T-cell cancers
This trial tests a new immune cell therapy (CAR T-cells) that targets CD5 found on certain T-cell cancers. It may be an option for people whose cancer has not responded to other treatments.

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 - 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 - NCT06364423RecruitingPhase 1/Phase 2
