Anti-DP treatment after stem cell transplant to prevent relapse
This early-phase trial tests an anti-DP medicine given after an allogeneic (donor) stem cell transplant. It aims to improve outcomes by targeting immune cells linked to certain transplant match types and reducing relapse risk.

Study drugs before transplant for myeloma with kidney problems
This Phase 2 trial tests whether a combination of anti-myeloma medicines given before stem cell transplant works well and is safe for people with multiple myeloma who also have kidney problems. It may help control the myeloma and prepare you for the transplant.
Milwaukee, WisconsinAges 18 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 - NCT04187703RecruitingEarly Phase 1
Testing azacitidine and decitabine for bone marrow cancers
This early-phase study tests whether combining two “epigenetic” medicines—azacitidine and decitabine—can improve outcomes for certain bone marrow cancers. It may help if you have a type of myelodysplastic syndrome (MDS) or MDS/MPN overlap that is expected to be sensitive to these medicines.
Cleveland, OhioAges 18 years+ - NCT04194619Recruiting
Study of pregnancy safety in women with rare blood-vessel diseases
This study looks at pregnancy and the early period after birth in women with rare diseases that affect blood vessels. It may help doctors understand risks and improve care for future pregnancies.
AngersAges 18–45 - NCT04210791Enrolling by invitation
Stem cell transplant using your own cells for AL amyloidosis
This trial tests whether an autologous stem cell transplant (using your own stem cells) can help people with newly diagnosed AL amyloidosis. It may be offered to help your body reset abnormal disease-producing cells, based on your health and test results.
Nanjing, JiangsuAges 18–75 - NCT04239157RecruitingPhase 2
Canakinumab shot for lower-risk MDS and related blood disorders
This trial tests canakinumab, a medication that blocks inflammation, given as a skin (subcutaneous) injection. It is for adults with lower-risk myelodysplastic syndromes (MDS) or a related condition (chronic myelomonocytic leukemia or CCUS) to see if it can improve blood counts and reduce problems like anemia or transfusion needs.
Houston, TexasAges 18 years+ - NCT04160910RecruitingPhase 2
Studying 5HTP to manage asthma symptoms in kids
This Phase 2 study tests whether 5HTP can help regulate asthma in children and teens who have mild to moderate asthma linked to allergies. It may be an option if your symptoms are allergy-related and you can follow study visits and questionnaires.
Indianapolis, IndianaAges 8–18 - NCT04146870Recruiting
Nutrition check after bone marrow transplant
This trial studies nutrition and nutritional status in people after a bone marrow (hematopoietic stem cell) transplant. It may help the hospital understand what nutritional support works best during recovery.
Suzhou, JiangsuAges 15–80 - NCT04223765RecruitingPhase 1
Testing a new CAR T-cell treatment for kappa cancers
This Phase 1 trial studies a lab-made immune therapy (CAR T cells) that targets “kappa” markers on certain lymphomas and CLL/SLL. It’s for people whose cancer has come back or didn’t respond to standard treatments, aiming to improve control of the disease.
Chapel Hill, North CarolinaAges 18 years+ - NCT04169737RecruitingPhase 2
