BrusselsAges 18–50 - NCT05417165RecruitingPhase 2
Pneumococcal vaccine plan for CLL or SLL patients
This Phase 2 study tests a specific plan for giving a pneumococcal vaccine in people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). It may help improve protection against pneumococcal infections in patients who have not started CLL/SLL treatment yet.
Columbus, OhioAges 18 years+ - NCT05417971Recruiting
Reduced-intensity chemo and radiation before a donor bone marrow transplant
This trial tests a lower-intensity chemotherapy and radiation plan before getting a bone marrow (stem cell) transplant from a related donor. It’s meant for people with blood cancers who are considered at higher risk of relapse with standard lower-intensity treatments.
Atlanta, GeorgiaAges 18 years+ - NCT05418088RecruitingPhase 1
CAR T-cell therapy for hard-to-treat B-cell cancers
This Phase 1 study tests lab-made immune cells (CAR T-cells) that target CD19, CD20, and/or CD22 in people with certain relapsed or refractory B-cell cancers. It may help by attacking cancer cells that still carry these targets, but eligibility is very specific and includes prior treatments and health/lab requirements.
Columbus, OhioAges 2 years+ - NCT05422027RecruitingPhase 1/Phase 2
Selinexor with VRd for high-risk newly diagnosed myeloma
This early-phase study tests whether selinexor combined with VRd (bortezomib, lenalidomide, and dexamethasone) can improve outcomes for people with high-risk, newly diagnosed multiple myeloma. You may be a candidate if you have certain lab/genetic signs of “high-risk” disease and haven’t had prior myeloma treatment.
Guangzhou, GuangdongAges 18 years+ - NCT05423691RecruitingPhase 1
Test drug CK0804 plus special T-cell therapy after ruxolitinib
This Phase 1 study tests CK0804 (plus T-regs, a type of immune cell approach) for people with myelofibrosis whose disease is not adequately controlled on ruxolitinib. It may help improve blood counts, symptoms, and/or the size of an enlarged spleen.
Sacramento, CaliforniaAges 18 years+ - NCT05425992Recruiting
Spanish-speaking families with leukemia or lymphoma
This study aims to improve communication and strengthen a child’s “medical home” (the main care team and coordination) for Spanish-speaking families. It focuses on families receiving cancer care at the Center for Cancer and Blood Disorders (CCBD).
Aurora, ColoradoAges Up to 22 years - NCT05426252RecruitingPhase 1/Phase 2
Lower-toxicity bone marrow conditioning for high-risk thalassemia
This trial tests a modified, lower-toxicity preparation (conditioning) before a bone marrow transplant in children and teens with high-risk thalassemia. It aims to reduce treatment side effects while still allowing transplant success for people who need a donor.
Toronto, OntarioAges 1–18 - NCT05430971Recruiting

This trial is a patient registry for people with blastic plasmacytoid dendritic cell neoplasm (BPDCN). It helps researchers learn more about the disease by collecting information from patients as they get care.
Miami, FloridaAges Any age - NCT05431257RecruitingPhase 2
Azacitidine plus venetoclax for older or unfit AML
This Phase 2 study tests whether the combination of azacitidine and venetoclax can help people with acute myeloid leukemia (AML) who can’t handle standard intensive chemotherapy, including some relapsed or refractory cases. It also involves extra optional-style lab testing on your leukemia (bio-banking and “-omics” profiling) to learn which drug sensitivities may matter.
CopenhagenAges 18 years+ - NCT05432466RecruitingPhase 3
Celiprolol vs placebo for vascular Ehlers-Danlos heart vessel fragility

St Louis, MissouriAges 18 years+ - NCT05436223RecruitingPhase 2
CD19 CAR-T for certain relapsed or refractory lymphoma
This trial tests a lab-made immune therapy (CD19 CAR-T) for adults whose B-cell non-Hodgkin’s lymphoma has come back or did not respond to standard treatments. It may help your immune system attack the cancer cells that carry a specific marker called CD19.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05436418RecruitingPhase 1/Phase 2
Lower-dose transplant medicines to prevent graft-versus-host disease
This early-phase study tests a lower dose of cyclophosphamide given after a stem cell transplant to prevent graft-versus-host disease (GVHD). It also uses sirolimus and mycophenolate to improve how well the donor immune system accepts the transplant, aiming to reduce side effects while keeping protection against GVHD.
