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+ - NCT04014374Recruiting
Safety study for stem cell transplant after mogamulizumab
This study tracks safety in adults who had a stem cell transplant after taking mogamulizumab. It looks at outcomes and side effects over time, helping doctors understand risks for future patients.
Milwaukee, WisconsinAges 18 years+ - NCT04014413Recruiting
Fecal transplant for gut and immune-related conditions
This trial studies whether fecal microbiota transplantation (FMT)—a medical procedure using stool from a screened donor to restore gut bacteria—can improve safety and outcomes for people with certain bowel, immune, and metabolic conditions. It may help if your symptoms are thought to be related to an unhealthy gut microbiome, though eligibility is broad and depends on specific safety factors.
Hong Kong, ShatinAges Any age - NCT04018118Recruiting
Study of the course of high eosinophil blood disease
This study follows people with long-term high eosinophils (a type of white blood cell) and related conditions to learn how the illness changes over time. It helps doctors understand patterns of organ involvement and outcomes, which may improve future care.
LilleAges Any age - NCT04024761RecruitingPhase 1
NK cell therapy for leukemia relapse after transplant
This Phase 1 study tests whether an infusion of special immune cells (NK cells) from a donor can help control leukemia or related blood cancers that come back or do not fully go away after a stem cell transplant. It also uses short chemotherapy to “make space” for the NK cells to work, and IL-2 to help them function.
Boston, MassachusettsAges 12 years+ - NCT04023019Recruiting
Hemophilia A trial for people with FVIII inhibitors
This trial studies a treatment approach for people with hemophilia A who develop antibodies (inhibitors) that block clotting factor FVIII. It may help those whose usual FVIII therapy is not working because of these inhibitors.
Atlanta, GeorgiaAges Any age - NCT04025450RecruitingPhase 1/Phase 2
Tested stronger combo for high-risk myeloma patients
This early-phase study compares two drug combinations—chidamide plus VRD versus VRD alone—to see which works better for primary high-risk multiple myeloma. The goal is to improve response while closely monitoring side effects and heart/lung safety.
Suzhou, JiangsuAges 18–80 - NCT04028531Recruiting
Understanding chronic lymphocytic leukemia in clinic patients
This study aims to learn more about chronic lymphocytic leukemia (CLL) and closely related conditions. It may help researchers better understand who gets CLL and how it behaves over time, which can improve future care.
Boston, MassachusettsAges 18 years+ - NCT04043494RecruitingPhase 3
Study of new treatment plans for childhood lymphoblastic lymphoma
This trial studies a treatment approach for children and teens newly diagnosed with lymphoblastic lymphoma. It may help doctors choose therapies based on genetic risk information from lab testing done on tumor samples.
GrazAges Up to 18 years - NCT04047641RecruitingPhase 1/Phase 2
Quizartinib with chemotherapy for new or returning leukemia
This trial tests a combination of anti-leukemia drugs (including quizartinib) together with chemotherapy for people with acute myeloid leukemia (AML), a rare mixed-type leukemia, or high-risk myelodysplastic syndrome (MDS). It may help by trying to better control cancer in people whose disease is newly diagnosed or has returned/not responded to prior treatment.
Houston, TexasAges 18 years+ - NCT04049539RecruitingPhase 1/Phase 2
Vyxeos for AML that stays after initial chemotherapy
This trial tests whether Vyxeos (a type of chemotherapy) can treat acute myeloid leukemia (AML) that did not fully go away after standard induction (“7+3”) chemotherapy. It targets people whose leukemia is still present in the bone marrow and need a stronger “re-induction” treatment.
Sacramento, CaliforniaAges 18–75 - NCT04053439Recruiting
Testing blood-clone risk to prevent chemotherapy complications
This study looks at a specific genetic/production change in blood-forming cells (“clonal hematopoiesis”) to understand who is more likely to have complications from lymphoma chemotherapy. It may help doctors predict risk and possibly reduce harmful side effects.
Toronto, OntarioAges 60 years+ - NCT04055818RecruitingPhase 1
Testing three medicines for high-risk sickle cell disease
This Phase 1 study tests whether nicotinamide, oral tetrahydrouridine, and decitabine can help people with high-risk sickle cell disease. It is mainly a safety-and-dosing study, but it also looks for signs the medicines may improve disease-related problems.

MRI measurements for epilepsy from a single brain blood vessel lump
This study uses special MRI scans to measure brain changes in people whose seizures are related to one cerebral cavernous malformation (a type of abnormal blood vessel in the brain). It aims to find a measurable “biomarker” from MRI that may help understand the epilepsy and the brain structure around it.
