Follow-up study comparing two rituximab options in new DLBCL
This study follows people who already took part in an earlier Phase III trial to see how well two rituximab medicines work over time. It looks at outcomes like how long participants live and how long the disease stays under control, and may help confirm whether the biosimilar is comparable to the original.
BeijingAges 18–80 - NCT04575883Recruiting
Bike interval training for teens with repaired heart defects
This study tests a structured “interval” bike exercise program to see if it’s safe and helpful for teens with certain repaired congenital heart conditions. It may help improve fitness while closely monitoring heart symptoms during training.
Edmonton, AlbertaAges 10–18 - NCT04555785RecruitingPhase 4
Testing platelet treatment in ICU patients after surgery
This trial studies whether a platelet-related treatment can work better in people in the ICU who need a platelet transfusion after surgery. It may help reduce bleeding by improving how platelets work when certain blood clotting proteins are already high.

CD19 CAR-T for children and young adults with B-cell blood cancers
This trial tests a one-time, lab-made immune cell treatment (CD19 CAR-T) for certain B-cell blood cancers in children and young adults. It may help people whose leukemia or lymphoma is not responding to standard treatment or has come back.
Aurora, ColoradoAges 1 month–30 years - NCT04523428RecruitingPhase 2
Second round of targeted pills after short venetoclax benefit
This trial studies whether repeating two targeted medicines—venetoclax plus acalabrutinib—for a limited time can control CLL or SLL after you had a partial response to earlier venetoclax-based treatment. It may help people who need retreatment but want another approach beyond the first limited course.
BrusselsAges 18 years+ - NCT04506593Recruiting
GI Motility diagnosis registry for people with digestion movement problems
This trial is a registry, meaning it collects information about people being evaluated for problems with how the gut moves. It may help doctors better diagnose gastrointestinal motility disorders in the future.
Indianapolis, IndianaAges Any age - NCT04508790RecruitingPhase 2
Leflunomide plus pomalidomide with dexamethasone for relapsed myeloma
This trial studies whether a combination of three medicines (leflunomide, pomalidomide, and dexamethasone) can better treat multiple myeloma that has come back or stopped responding. It may help people who are not good candidates for transplant and who have measurable disease.
Duarte, CaliforniaAges 18 years+ - NCT04518475RecruitingPhase 4
Eltrombopag with rituximab versus eltrombopag alone for ITP
This trial compares two treatment approaches for adults with primary immune thrombocytopenia (ITP), a condition where platelet counts are too low. It looks at whether adding rituximab to eltrombopag helps control ITP better and more safely.
TianjinAges 18–60 - NCT04563520RecruitingPhase 3
Testing the safety of aPCC after emicizumab in hemophilia A
This study looks at whether aPCC (a clotting medicine) is safe to use for bleeding safety in people with hemophilia A who are already taking emicizumab. It mainly checks side effects and safety after switching to or using aPCC when needed.
Atlanta, GeorgiaAges 6 years+ - NCT04493164RecruitingPhase 2
CPX-351 plus ivosidenib for IDH1-mutated leukemia or high-risk MDS
This trial tests CPX-351 together with ivosidenib in people with IDH1-mutated acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). It aims to improve disease control, especially in tumors with a specific genetic change called IDH1.
Houston, TexasAges 18 years+ - NCT04587687RecruitingPhase 2
Brentuximab plus bendamustine for relapsed follicular lymphoma
This Phase 2 trial studies the combination of brentuximab vedotin and bendamustine in people whose follicular lymphoma has come back or did not respond. It aims to shrink the lymphoma and improve outcomes after at least one prior treatment.
Sacramento, CaliforniaAges 18 years+ - NCT04558736RecruitingPhase 2
Haploidentical transplant for severe aplastic anemia in children
This trial tests a “half-matched” stem cell transplant for children and teens with severe aplastic anemia when a fully matched donor isn’t available. It may help rebuild blood-making cells after prior treatments did not work well enough.
Memphis, TennesseeAges Up to 21 years - NCT04515810Recruiting
Mobile app coaching for planning care after serious cancer
This study tests a mobile health app (PACT) to help people with advanced cancer talk and plan for future care. It may help you and a loved one stay engaged in advance care planning (planning what care you want and who should speak for you).
Manhasset, New YorkAges 18 years+ - NCT04545762RecruitingPhase 1
Anti-CD19 CAR-T for certain relapsed lymphoma
This Phase 1 study tests an anti-CD19 CAR-T cell treatment in adults with specific types of relapsed or treatment-resistant non-Hodgkin lymphoma. It may help by finding and attacking lymphoma cells that carry the CD19 marker, but it’s early-stage and eligibility is strict.
San Francisco, CaliforniaAges 18 years+ - NCT04450927Enrolling by invitation
Collecting health data from NHLBI patients and donors
This study collects information about standard care for people seen by the NHLBI, and also about donors. It helps researchers understand what happens in real-world care, which can improve future treatment decisions.
Bethesda, MarylandAges 2–120 - NCT04398628Recruiting
Study of non-cancer blood disorders in people with bleeding or clotting
This study follows people with inherited or acquired non-cancer blood disorders to better understand symptoms, causes, and how different treatments work over time. You may be placed into a disorder-specific group, depending on your diagnosis and testing results.
Phoenix, ArizonaAges Any age - NCT04428489Enrolling by invitation
Follow-up for low blood counts without MDS
This study follows people with ongoing low blood counts (red cells, white cells, and/or platelets) to better understand their condition when it does not meet criteria for MDS. It may help improve how persistent blood count problems are evaluated over time.

Test drug for adults with beta thalassemia intermedia
This trial studies an investigational medicine in adults with beta thalassemia intermedia (including non-transfusion dependent thalassemia). The goal is to see how well the treatment works and how safe it is for people whose hemoglobin runs in a certain range.
Oakland, CaliforniaAges 18 years+ - NCT04402086Recruiting
