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+ - 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+ - NCT05430971Recruiting
BPDCN international registry for patients to be followed over time
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 - 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 - NCT05447442Recruiting
Use a pre-surgery plan to treat anemia before an operation
This trial looks at whether following a hospital guideline to treat anemia before surgery helps patients have better pre-op care. You may be eligible if you have anemia found during a pre-anesthesia clinic visit.
Bangkok, BangkokAges Any age - NCT05444361Enrolling by invitation
Ultrasound freezing treatment for pain after mastectomy
This trial tests a “freezing” nerve procedure guided by ultrasound to help reduce pain after mastectomy. It aims to lessen postoperative pain by temporarily calming specific nerves involved in chest wall sensation.
Los Angeles, CaliforniaAges 18 years+ - NCT05443321Enrolling by invitation
Health information sharing during hospital transfers
This trial studies whether sharing patients’ health information between hospitals during transfers can improve outcomes. You may be included if you are moved from a specific partner hospital to Brigham and Women’s Hospital and admitted to certain hospital units.
Boston, MassachusettsAges 18 years+ - NCT05434598Recruiting
Whole-genome testing added to standard testing for MDS
This study checks whether adding whole-genome sequencing (a deeper look at DNA) alongside standard genomic tests helps in evaluating myelodysplastic syndrome (MDS). It aims to see if this extra testing is useful and acceptable during routine care—especially for people newly being worked up for MDS.
St Louis, MissouriAges 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+ - 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+ - NCT05451979Recruiting
Exercise training at home for kids after heart transplant
This trial tests a home-based, short bursts exercise program (HIIT using the MedBIKE™ system) for children who had a heart transplant at least 6 months ago. It may help improve fitness and safety after transplant, while checking which kids can participate without heart rhythm or symptom problems.
Edmonton, AlbertaAges 10–18 - NCT05443425RecruitingPhase 1
Leflunomide plus steroids for acute graft-versus-host disease
This early-phase trial tests whether adding leflunomide to standard steroid treatment can better control acute graft-versus-host disease (aGvHD) after a stem cell transplant. It may help reduce the immune reaction that damages the body while keeping treatment safe and manageable.
Duarte, CaliforniaAges 18 years+ - NCT05432635RecruitingPhase 1
CAR T-cell and vaccine treatment after stem cell transplant
This Phase 1 study tests a customized immune-cell treatment (CAR T-cells) plus a vaccine given after stem cell transplant for certain aggressive B-cell non-Hodgkin lymphomas. It aims to help your immune system better recognize and attack the lymphoma and to see how safe the approach is.
Duarte, CaliforniaAges 18 years+ - NCT04146376Recruiting
Study of medicines for Von Willebrand disease during pregnancy
This study looks at how well a Von Willebrand disease treatment plan works during pregnancy, and whether some patients need extra “adjusting” of medicine. It may help prevent bleeding problems by matching treatment to each person’s lab results later in pregnancy.
Aurora, ColoradoAges 18 years+ - NCT05192122RecruitingPhase 1
Stop maintenance medicine in multiple myeloma with low remaining disease
This early-phase study looks at whether it’s safe to stop the usual “maintenance” medicine after a strong response in multiple myeloma. It aims to see if stopping treatment for people with very low remaining disease reduces drug exposure without allowing relapse too soon.
Chicago, IllinoisAges 18 years+ - NCT05389423RecruitingPhase 1
Pomalidomide plus chemotherapy for HIV-related lymphoma
This Phase 1 study tests whether a combination of pomalidomide and a dose-adjusted chemotherapy plan (EPOCH), with or without rituximab, can treat certain aggressive B-cell lymphomas in people living with HIV. It aims to find a safe dosing approach and see how well the treatment works for specific lymphoma types or high risk of spread to the brain.

Early vs delayed treatment for high-risk CLL: cost study
This study compares early treatment versus delaying treatment in newly diagnosed people with high-risk CLL/SLL who feel well. It mainly looks at the overall “costs and value” of each approach and asks patients to complete short health and quality-of-life questionnaires.
Vancouver, British ColumbiaAges 18 years+ - NCT05366881Recruiting
Blood test study to spot early cancer signal and cancer leftovers
This observational study checks whether a blood test (a “cfDNA” test) can detect early signs of cancer or small amounts of cancer left after treatment. It may help doctors use a simple blood sample to improve cancer detection and follow-up.
Duarte, CaliforniaAges 40 years+ - NCT05377307Recruiting
Long-term follow-up for gene-edited immune cell therapy
