Donor immune cells after bone marrow transplant for high-risk blood cancers
This trial studies giving donor lymphocyte (immune) infusions after a bone marrow transplant for people with high-risk blood cancers. The goal is to help the immune system better fight the cancer and improve outcomes after transplant.
Bethesda, MarylandAges 12–120 - NCT05328258RecruitingPhase 3
Triptorelin to help protect fertility during cancer chemotherapy
This Phase 3 study tests whether a hormone medicine called triptorelin (a GnRH “fertility-protecting” medicine) can better protect ovarian function while you receive chemotherapy. The goal is to help preserve fertility and reduce the risk of early ovarian failure from cancer treatment.
GothenburgAges 14–42 - NCT05333367Recruiting
Study of how a light treatment causes immune cell death
This trial looks at how “extracorporeal photochemotherapy” (a light-based treatment done outside the body) works at the cellular level. It may help improve treatment and control for people dealing with immune reactions after transplant or certain blood/skin conditions.
BesançonAges 18–85 - NCT05333302RecruitingPhase 1
CAR-T treatment study for children and young adults with CD19 leukemia
This Phase 1 study tests a CAR-T cell treatment made to target CD19 in children and young adults whose leukemia or lymphoma has come back or did not respond to prior treatment. It aims to see how the treatment works and how safe it is in this age group.
Minsk, Minsk OblastAges 1–30 - NCT05334823RecruitingPhase 2
CAR T-cell treatment for CD19-positive relapsed leukemia in children
This Phase 2 trial tests pCAR-19B, a customized immune-cell treatment for children and teens with CD19-positive B-ALL that has come back or did not respond to standard therapy. If eligible, you would receive the cell infusion after cell collection and testing to make sure the leukemia cells have the right marker.
Beijing, Beijing MunicipalityAges 3–21 - NCT05334615Recruiting
Study of blood clot problems after COVID or flu
This study looks at blood clot–related complications after COVID-19 (and in some cases flu) in adults admitted to the hospital. It may help doctors better understand and manage these complications.
Iowa City, IowaAges 18–99 - NCT05334693RecruitingPhase 1/Phase 2
Donor immune cells to help prevent AML return after treatment
This study tests an “immune cell therapy” made from a family donor to help children and young adults with AML stay in remission after chemotherapy. It may help reduce the chance that AML comes back, but eligibility depends on remission status, donor suitability, and avoiding certain infections or liver issues.
Minsk, Minsk OblastAges 6 months–21 years - NCT05336383RecruitingPhase 2
Radiation after prior CAR T for relapsed multiple myeloma
This trial tests giving “salvage” radiation (radiation meant to control remaining cancer) after you’ve already had BCMA CAR-T therapy for multiple myeloma. It’s for people whose PET or other scan still shows active myeloma at least 30 days after CAR-T, and who have a spot that radiation can target.
Houston, TexasAges 18 years+ - NCT05336201RecruitingPhase 2
Brain training program for teens with sickle cell disease
This Phase 2 study tests a cognitive (thinking) training program to help teens with sickle cell disease prepare for the changes in their care as they grow older. It may help with skills like learning, attention, and planning for transition to adult care.
Birmingham, AlabamaAges 10–18 - NCT05336812RecruitingPhase 2
Acalabrutinib with venetoclax or obinutuzumab for untreated CLL
This Phase 2 trial studies how well acalabrutinib works when combined with either venetoclax or obinutuzumab in people with untreated chronic lymphocytic leukemia (CLL). It aims to improve disease control while checking safety and tolerability.
Columbus, OhioAges 18 years+ - NCT05338190RecruitingPhase 3
Belimumab added to rituximab for chronic immune thrombocytopenia
This Phase 3 study tests whether adding an injection called belimumab (or a placebo) to rituximab works better and is safe for adults with long-lasting immune thrombocytopenia (ITP). You may be eligible if your platelet counts stay low despite prior steroid and/or IVIG treatment and if infections, vaccines, and other health conditions meet the study rules.
CréteilAges 18 years+ - NCT05338931RecruitingPhase 1/Phase 2
AT101 for relapsed or refractory B-cell lymphoma patients
This trial studies AT101 to see how safe it is, what side effects it causes, and whether it can help people with B-cell non-Hodgkin lymphoma that has come back or did not respond to treatment. It may be an option if your usual treatments are no longer working or aren’t suitable for you.
SeoulAges 19 years+ - NCT05340465RecruitingPhase 2
IV iron in preterm babies to reduce blood transfusions
This Phase 2 study tests whether giving a specific IV iron (darbe plus IV iron) can help preterm babies need fewer blood transfusions while still keeping their iron levels in a safe range. It focuses on babies in the NICU who were born early, and it compares transfusion use and iron sufficiency over time.
Seattle, WashingtonAges Up to 3 days - NCT05341557RecruitingPhase 1
First-in-human drug study for advanced cancers and lymphoma
This Phase 1 trial tests BPI-371153, a new treatment, in people with advanced solid tumors or relapsed or refractory lymphoma whose cancer has returned or progressed after standard care. The goal is to find a safe dose and learn whether it can shrink tumors or help control disease.
Chaoyang, Beijing MunicipalityAges 18 years+ - NCT05342584RecruitingPhase 1
Venetoclax plus intensive chemo for AML and advanced MDS
This early-phase study tests whether venetoclax combined with intensive chemotherapy can treat AML (acute leukemia) and certain advanced MDS. It’s for people who are newly diagnosed (or certain high-risk blood cancers) and can safely tolerate strong treatment.
The Bronx, New YorkAges 18–75 - NCT05344833RecruitingPhase 2
Isatuximab and lenalidomide after transplant for myeloma
This Phase 2 study tests whether adding isatuximab and lenalidomide after an autologous stem cell transplant can keep multiple myeloma from coming back when tests show leftover (minimal) disease. If it works, it may improve how long you stay in response.
Chicago, IllinoisAges 18 years+ - NCT05348213RecruitingPhase 2
Targeted drugs plus R-ICE chemo for relapsed lymphoma
This Phase 2 trial studies targeted drugs combined with R-ICE chemotherapy in people with diffuse large B-cell lymphoma (DLBCL) that has come back or hasn’t responded. It may help shrink the lymphoma after prior treatment.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05353348Recruiting
Program to treat mild anemia around heart surgery
This trial tests a combined treatment plan to improve anemia (low blood count/iron levels) before and around the time of major elective heart surgery. It may help reduce the need for blood transfusions and support safer recovery.
Hangzhou, ZhejiangAges 18 years+ - NCT05355051RecruitingPhase 2
Azacitidine plus pembrolizumab for Hodgkin lymphoma after relapse
This Phase 2 study tests azacitidine together with pembrolizumab in people whose Hodgkin lymphoma has come back or did not respond (relapsed/refractory). It aims to see whether this combination can control cancer and improve outcomes, especially when standard high-dose chemotherapy is not an option.
Houston, TexasAges 1 year+ - NCT05356325Recruiting
Testing FGF23 in anemia with and without kidney disease
This study looks at a blood hormone called FGF23 and whether it is linked to heart (cardiovascular) problems in people with anemia. It also compares people with anemia who do and do not have chronic kidney disease, which may help researchers understand risk and targets.
CórdobaAges 18–85 - NCT05357651RecruitingPhase 1
LB1410 study for advanced lung, colon, and other cancers
This Phase 1 trial tests LB1410, a new cancer treatment, to see if it is safe and may work for people with advanced cancers. It focuses on specific cancer types and requires certain prior treatments and lab test results.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05357781Recruiting

This trial studies whether giving immunoglobulins (antibody medicines) can improve fatigue in people with multiple sclerosis (MS). It will enroll only people whose MS and fatigue are stable and meet specific blood/health criteria.
Bern, Canton of BernAges 18–65 - NCT05357794RecruitingPhase 2
Skin-directed radiation plus brentuximab for lymphoma skin disease
This Phase 2 trial studies whether giving very low-dose total-skin electron beam radiation at the same time as brentuximab vedotin can control mycosis fungoides (a lymphoma that affects the skin). It’s for people whose disease has returned or hasn’t responded to prior treatment, especially if the tumor marker CD30 is present.
Houston, TexasAges 18 years+ - NCT05359991Recruiting
