Cincinnati, OhioAges 1–39 - NCT03758989RecruitingPhase 2
PET-guided treatment and monitoring for limited-stage lymphoma
This Phase 2 study tests a treatment approach guided by PET scans, plus non-invasive monitoring, for adults with limited-stage diffuse large B-cell lymphoma (a type of lymphoma).

This study checks unborn babies’ heart signals using special scans during pregnancy and then checks the baby’s heart shortly after birth. It may help researchers understand why certain high-risk pregnancies can lead to fetal demise and improve care.
Madison, WisconsinAges 18 years+ - NCT03737955RecruitingPhase 2
Gemtuzumab for measurable residual leukemia after initial treatment
This trial studies whether fractionated gemtuzumab can eliminate tiny, hard-to-see leukemia cells left after standard chemotherapy. It targets adults with acute myeloid leukemia (AML) who have measurable residual disease (MRD) rather than active leukemia in the blood.
Seattle, WashingtonAges 18 years+ - NCT03719105RecruitingEarly Phase 1
Chemo plus immunotherapy with donor stem cell transplant for NK lymphoma
This early-phase study tests a combination treatment—chemo, immunotherapy, and a donor stem cell transplant—for certain aggressive NK/T-cell lymphomas. It may help patients who have advanced-stage disease by trying to improve long-term control of the cancer.
Birmingham, AlabamaAges 1–31 - NCT03858205Recruiting
Low-dose radiation to relieve pain from bone tumors
This trial studies whether low-dose radiation can reduce pain from a specific bone lesion caused by multiple myeloma. It may help people whose main problem is painful bone metastasis, with targeted treatment to the painful spot.
Duarte, CaliforniaAges 18 years+ - NCT03829540RecruitingPhase 1
CD4 CAR T therapy for certain CD4+ blood cancers
This early-phase (Phase 1) study tests a lab-made immune cell treatment (CD4 CAR T) for people with CD4+ leukemia or lymphoma that has come back or did not respond to standard treatment. The goal is to check safety and see how well the treatment works.
Miami, FloridaAges 12 years+ - NCT03773159Recruiting
Testing a blood clot test using whole blood flow
This trial tests a new lab device that measures how well your body forms primary blood clots while blood is kept in flowing conditions. It may help doctors better assess bleeding or clotting tendencies and guide future care.
BesançonAges 18 years+ - NCT03850418RecruitingPhase 2
Azacitidine for blood chimerism changes after transplant
This Phase 2 study tests whether azacitidine can improve outcomes when donor blood “chimerism” starts dropping after an allogeneic stem cell transplant. It’s for people with AML, MDS, MPN, or CMML who are experiencing early warning signs in their blood counts after transplant but without clear relapse in the bone marrow.
Detroit, MichiganAges 18–75 - NCT03874052RecruitingPhase 1
Ruxolitinib plus venetoclax and azacitidine for relapsed AML
This early-phase study tests a combination of ruxolitinib with venetoclax, with or without azacitidine, for adults whose acute myeloid leukemia (AML) has come back or does not respond to treatment. It may help by stopping cancer cells from growing and improving blood counts, with the exact plan guided by the study arm you’re assigned to.
Columbus, OhioAges 18 years+ - NCT03836300Enrolling by invitation
Parent-infant coaching for families with young diagnoses
This study tests a parent-and-infant coaching program for babies and caregivers. It aims to see whether the program helps after an early diagnosis when English is used at home.
Research Triangle Park, North CarolinaAges Up to 99 years - NCT03810196Recruiting
Stem cell addback after transplant to treat viral or fungal infection
This study tests a stem cell “addback” treatment after a specific type of transplant (with certain immune cells removed). It may help the body recover faster and fight serious viral or fungal infections in children and teens.
Philadelphia, PennsylvaniaAges Up to 25 years - NCT03823534RecruitingPhase 3
Study pain control after preventive femur bone surgery
This Phase 3 study tests a pain medicine plan used after preventive surgery to place a metal rod inside the thigh bone (femur) before a fracture happens. The goal is to find an approach that controls post-surgery pain while being safe for the right patients.
St Louis, MissouriAges 18 years+ - NCT03815279Enrolling by invitationPhase 2
Trial for active or high-risk smoldering myeloma treatments
This Phase 2 study tests a treatment approach for adults with active multiple myeloma (MM) or a high/intermediate-risk “smoldering” MM that hasn’t been treated yet. It may help by trying to control the disease earlier or more effectively, depending on what the trial drug(s) do.
ReykjavikAges 18 years+ - NCT03850366RecruitingPhase 2
Haploidentical stem cell transplant with two post-transplant medicines
This trial tests a way to treat certain blood cancers using a stem cell transplant from a partially matched (haploidentical) donor. It aims to make the transplant safer and reduce the chance of the immune reaction that can follow transplant, using post-transplant cyclophosphamide and bortezomib.
Detroit, MichiganAges 18–65 - NCT00582621Recruiting
Family history study to support genetic testing research
This study collects family and medical history to better understand inherited causes of blood cancers (like lymphoma) and related conditions. It may help researchers build genetic findings that could improve how families understand their risk and future care.
Basking Ridge, New JerseyAges Any age - NCT02593565Recruiting

Haplo transplant for severe bone marrow failure using donor cells
This trial tests a stem cell transplant from a closely matched but not fully matched family donor (haploidentical), with chemotherapy after the transplant to help prevent graft-versus-host disease (GVHD). It may help people with severe aplastic anemia, certain MDS after transformation, or PNH when other treatments have not worked or are not available.
Bethesda, MarylandAges 4–75 - NCT03628612Enrolling by invitationPhase 2
