Study of immune cells in blood cancers
This study looks at immune cells (monocytes) in people with certain blood cancers. Researchers want to understand how these cells behave and change over time. You can join if you are newly diagnosed and haven't started treatment yet.

Chemo + venetoclax + immunotherapy for adult ALL
This trial combines a kid-inspired chemotherapy backbone with a targeted pill (venetoclax) and immunotherapy (special antibodies) to treat adults with Ph-negative acute lymphoblastic leukemia (ALL). The goal is to use a more effective, less toxic approach developed for children.
Tianjin, Tianjin MunicipalityAges 14–60 - NCT06943872RecruitingPhase 3
Comparing new treatments for relapsed CLL or SLL
This study tests a combination of sonrotoclax plus obinutuzumab or rituximab versus the current standard venetoclax plus rituximab for people whose CLL or SLL has come back or not responded to previous treatment. The goal is to see which approach helps keep the cancer from growing longer.
Laguna Hills, CaliforniaAges 18 years+ - NCT07451054RecruitingPhase 1
Stem cells plus CAR T-cells for lymphoma
This trial tests a new treatment that combines your own stem cells with special immune cells (CAR T-cells) that target a marker called CD45 on lymphoma cells. It may help people whose lymphoma has not responded to multiple prior therapies.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07188740RecruitingPhase 1
Metformin to target leukemia-related mutation during remission
This trial tests if metformin can reduce a specific mutation (DNMT3A R882) in people with acute leukemia who are in remission. The goal is to see if it helps prevent relapse.
Tianjin, Tianjin MunicipalityAges 14 years+ - NCT07739654RecruitingPhase 3
Modified chemotherapy combo for relapsed large b-cell lymphoma
This study compares two chemotherapy regimens for people with diffuse large B-cell lymphoma that has returned or not responded to earlier treatment. The goal is to see if a modified version is as effective with fewer side effects.
Lahore, Punjab ProvinceAges 18 years+ - NCT07131059Recruiting
Study for MRD-positive AML in remission
This trial is for people with acute myeloid leukemia (AML) who are in remission but still have tiny traces of leukemia cells that can be found with sensitive tests (called MRD-positive). The study is testing a new treatment approach to try to get rid of those remaining cells and prevent the cancer from coming back.
Tianjin, Tianjin MunicipalityAges 14 years+ - NCT06529250Recruiting
Medium-dose chemo for CEBPA double-mutated AML
This trial tests a medium-dose combination of three chemotherapy drugs (homoharringtonine, cytarabine, and daunorubicin) specifically for people with a newly diagnosed type of AML that has two common CEBPA gene mutations. It aims to see if this treatment works well and is safe.
Tianjin, Tianjin MunicipalityAges 14–54 - NCT05389293RecruitingPhase 2
Mosunetuzumab with or without zanubrutinib for follicular lymphoma
This trial studies mosunetuzumab alone or combined with zanubrutinib to treat people with follicular lymphoma that is advanced or causing problems. It’s meant to see which approach works better and is safe for long-term treatment.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06568315RecruitingPhase 3
Calcium plus multivitamins for mother and baby
This study tests whether taking a daily multivitamin with calcium, in addition to standard prenatal vitamins, improves iron levels and health for you and your baby. You would switch from your usual iron folic acid pills to the study supplements.
OuagadougouAges 15 years+ - NCT05731141Recruiting
Study of lymphatic birthmarks and related genetic conditions
This study follows people who have lymphatic anomalies (lymphatic birthmarks) and sometimes related vascular or genetic conditions. It aims to better understand how these problems develop and what genetic causes may be involved.
Bethesda, MarylandAges 1 day–100 years - NCT06838949RecruitingPhase 2
Herombopag for ITP in patients age 60 and older
This trial tests a medication called Herombopag to raise platelet counts in adults aged 60 or older with immune thrombocytopenia (ITP). The goal is to see if it is safe and effective for this age group.
TianjinAges 60 years+ - NCT06784336RecruitingPhase 2
Testing starch and a drug after stem cell transplant
This trial tests if adding a special starch and a drug called deferasirox can improve recovery for people who have a stem cell transplant for blood disorders. The starch may help with gut health and the drug reduces iron, which might help prevent complications.
Ann Arbor, MichiganAges 18 years+ - NCT06718439Recruiting

Checking a thigh vein spot for emergency IV access
This study looks at the anatomy (location and size) of a vein in the inner thigh to see if it can be used as an alternative “rescue” spot when typical IV access is difficult. It may help emergency teams place lifesaving IV lines faster in future patients.
Rochester, MinnesotaAges Any age - NCT04854278Recruiting
Operating room computer tool to reduce blood vessel procedure errors
This trial tests a new “black box” monitoring system in the operating room to spot mistakes and help prevent them during planned blood vessel procedures. It may improve safety by learning from real procedure events and error patterns.
