Recruiting studies
- NCT06346912RecruitingEarly Phase 1
CAR-T cell therapy for relapsed B-cell blood cancers
This trial tests a special type of immune therapy called CD19-BAFF CAR-T cells for people whose B-cell acute lymphoblastic leukemia or B-cell non-Hodgkin lymphoma has come back or not responded to standard treatment. The therapy uses your own modified immune cells to target and kill cancer cells.
Hangzhou, ZhejiangAges 18 years+ - NCT04532268RecruitingEarly Phase 1
CD19 CAR-T for relapsed or resistant B-cell blood cancers
This early-phase study tests “humanized” CD19 CAR-T therapy for people whose B-cell acute lymphoblastic leukemia (ALL) or B-cell lymphoma (NHL) has come back or didn’t respond. It’s designed to help the immune system recognize and attack cancer cells carrying the CD19 marker.
Hangzhou, ZhejiangAges 3–75 - NCT05289687RecruitingPhase 2
Daratumumab for hard-to-clear T-cell leukemia traces
This Phase 2 trial tests daratumumab (a targeted antibody medicine) in people with T-cell ALL whose leukemia is not fully gone at very low levels. The goal is to eliminate “minimal residual disease” (MRD) that can predict relapse, so treatment may be more effective after intensive chemotherapy.
Chicago, IllinoisAges 18 years+ - NCT05601726RecruitingPhase 1/Phase 2
Study of a new drug for hard-to-treat AML or high-risk MDS
This early study tests a new medicine (ABD-3001) to see if it’s safe and tolerable, how the body handles it, and whether it shows early signs of helping people with relapsed or hard-to-treat AML or high-risk MDS. It may be an option if standard treatments have already failed and you can’t receive a stem cell transplant.
Marseille, FranceAges 18 years+ - NCT06208735RecruitingPhase 1
CLIC-2201 for relapsed or refractory B-cell cancers
This early-phase trial tests a new treatment called CLIC-2201 for people whose B-cell lymphoma or leukemia has not responded to other treatments or has come back. It aims to see if this therapy can help when other options have failed.
Calgary, AlbertaAges 1 year+ - NCT03016806Recruiting
Umbilical cord blood transplant from unrelated donors
This trial studies transplanting healthy blood-forming cells from an umbilical cord blood donor who is not related to you. It may help people with certain blood cancers, immune disorders, or other serious diseases when a standard transplant plan is needed.
Rochester, New YorkAges 2 months–75 years - NCT04187105RecruitingPhase 2
Total marrow radiation using a targeted intensity plan before transplant
This Phase 2 study tests a more precise type of whole bone-marrow radiation before a stem cell transplant. It may help patients with certain high-risk blood cancers by preparing the body for transplant more safely and effectively.
Chicago, IllinoisAges 18–75 - NCT04099966RecruitingPhase 2
Stem cell transplant to treat high-risk blood cancers
This trial tests a specialized donor stem cell transplant to treat high-risk problems in the blood and bone marrow, including some cancers and non-cancers. It may help by using donor immune cells designed to better control the disease after transplant.
Valhalla, New YorkAges 1 day–30 years - NCT05328258RecruitingPhase 3
Triptorelin to help protect fertility during cancer chemotherapy
This Phase 3 study tests whether a hormone medicine called triptorelin (a GnRH “fertility-protecting” medicine) can better protect ovarian function while you receive chemotherapy. The goal is to help preserve fertility and reduce the risk of early ovarian failure from cancer treatment.
GothenburgAges 14–42 - NCT05586074RecruitingPhase 3
Test drug HEC73543 against chemo for FLT3-mutated AML
This Phase 3 study compares HEC73543 versus standard “salvage” chemotherapy in adults with AML that has come back or did not respond after first treatment. It’s designed for people whose leukemia has an FLT3-ITD mutation and may help improve response and outcomes.
HanzhouAges 18 years+ - NCT06984536RecruitingPhase 2
Lowered immune drug plus mini transplant method for preventing graft vs host disease
This trial tests a new combination of medicines to prevent graft-versus-host disease (GVHD) in patients with leukemia or myelodysplastic syndromes receiving a stem cell transplant from a half-matched donor. It aims to see if using less anti-thymocyte globulin (ATG) plus a simpler post-transplant cyclophosphamide (PTCy) regimen works as well as standard care with fewer side effects.
BeijingAges 12–65 - NCT03765177RecruitingPhase 1/Phase 2
CLIC-1901 for CD19-positive blood and lymphoma cancers
This trial studies a gene-modified cell treatment called CLIC-1901 for people whose CD19-positive cancer has come back or did not respond to prior treatment. It may help shrink the cancer by targeting a protein called CD19 on cancer cells.
Vancouver, British ColumbiaAges 18–75 - NCT05626400Recruiting
CAR T for relapsed T-ALL or T-LBL with CD7
This trial tests a type of immune therapy (CAR T cells) called Senl-T7 in people whose T-cell leukemia or lymphoma has come back or did not respond. It aims to target cancer cells that carry a marker called CD7.
Beijingcun, HebeiAges 2–70 - NCT01515527RecruitingPhase 2
Cladribine plus low-dose cytarabine and decitabine for AML or MDS
This Phase 2 study tests a combination chemotherapy plan (cladribine, low-dose cytarabine, and decitabine) for people with acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). It aims to shrink the leukemia/MDS and improve outcomes, including for certain people who may not tolerate standard treatment.
Houston, TexasAges 60 years+ - NCT05010564RecruitingPhase 1
TRICAR-ALL CAR-T treatment for tough childhood leukemia
This Phase 1 trial tests a customized CAR-T cell therapy for children and young adults with B-cell acute lymphoblastic leukemia (B-ALL) that keeps coming back or doesn’t respond to treatment. It aims to find a safer and effective way to control leukemia by targeting specific markers on the leukemia cells.
Houston, TexasAges 1–25 - NCT03383575RecruitingPhase 2
Azacitidine plus enasidenib for IDH2-mutant MDS
This trial tests whether combining azacitidine with enasidenib helps people with myelodysplastic syndrome (MDS) that has an IDH2 mutation. It’s designed for people who are either new to “hypomethylating” treatment or whose MDS returned/worsened after it.
Baltimore, MarylandAges 12 years+ - NCT06709469RecruitingPhase 1
CAR-T cell therapy for relapsed/refractory acute lymphoblastic leukemia
This trial tests a new CAR-T cell therapy for children, teens, and young adults with acute lymphoblastic leukemia that has not responded to standard treatment. The goal is to see if the therapy can put the leukemia into remission so the patient may then have a stem cell transplant.
