MRI measurements for epilepsy from a single brain blood vessel lump
This study uses special MRI scans to measure brain changes in people whose seizures are related to one cerebral cavernous malformation (a type of abnormal blood vessel in the brain). It aims to find a measurable “biomarker” from MRI that may help understand the epilepsy and the brain structure around it.

BudapestAges 18–65 - NCT04167696RecruitingPhase 1
Dose-finding drug study for AML or MDS after standard options fail
This Phase 1 trial tests CYAD-02 to find the safest and recommended dose for people with AML or MDS that has returned or did not respond to prior treatment. It may help if you have limited treatment options, but participation also requires meeting specific heart, lung, and lab safety requirements.
Jacksonville, FloridaAges 18 years+ - NCT04432714RecruitingPhase 1/Phase 2
Lenalidomide plus R-DA-EPOCH for MYC-rearranged lymphoma
This early-phase study tests whether lenalidomide combined with R-DA-EPOCH can treat untreated diffuse large B-cell lymphoma (DLBCL) that has a MYC rearrangement. It may help control the lymphoma, but it’s also designed to find the safest and most effective dosing.
Nanjing, JiangsuAges 18–60 - NCT04477967Recruiting
Creating a liver transplant biobank for children
This trial sets up a long-term collection of medical information and samples from children who have had a liver transplant. It helps doctors study outcomes over time and improve care for future patients.
Chongqing, Chongqing MunicipalityAges 1 month–18 years - NCT04283006RecruitingEarly Phase 1
CAR T-cell treatment for hard-to-treat B-cell blood cancers
This early-phase trial tests a special kind of immune cell treatment (CAR T cells) that targets CD20 and CD22 in people with relapsed or refractory B-cell cancers. It may help by attacking cancer cells that survived prior treatments, but it is still being studied for safety and early effectiveness.
Hangzhou, ZhejiangAges 3–70 - NCT02657785RecruitingPhase 2/Phase 3
Treating newly diagnosed brain lymphoma with added medicines into CSF
This trial studies a treatment plan for people with newly diagnosed non-Hodgkin lymphoma that has spread to the brain and covering tissues (meninges). It combines medicines given through the bloodstream with immunotherapy placed into the fluid around the brain (CSF) to improve control of the lymphoma.
Beijing, Beijing MunicipalityAges 18–75 - NCT04538937Recruiting
Study of high eosinophils causing lung/airway damage
This registry study looks at adults with high eosinophils (a type of immune cell) that are believed to be causing damage in the airways or lungs. It aims to better identify these eosinophils and understand what is going on so future treatments can improve.
InnsbruckAges 18 years+ - NCT04532281RecruitingEarly Phase 1
CD19 CAR-T therapy for relapsed or resistant blood cancers
This early-phase study tests a treatment called CD19 CAR-T, made from your immune cells, for people whose CD19+ blood cancer has come back or did not respond. It may help your body better recognize and attack cancer cells, but eligibility is tight and the study is still early.
Hangzhou, ZhejiangAges Any age - NCT04532203RecruitingEarly Phase 1
CAR-T therapy for leukemia or lymphoma in the brain
This early-phase study tests CAR-T cells—immune cells engineered to recognize cancer—for people whose leukemia or lymphoma has spread to the central nervous system (the brain/spinal fluid). It may help shrink or control hard-to-treat (relapsed or refractory) cancers in the brain.
Hangzhou, ZhejiangAges 3–75 - NCT04603872RecruitingEarly Phase 1
CAR-T plus dasatinib for hard-to-treat B-cell cancers
This early study tests a cancer-fighting treatment that uses CAR-T cells together with dasatinib for people whose B-cell cancers have come back or did not respond. It aims to improve control of the cancer in cases that are often resistant to standard treatment.
Hangzhou, ZhejiangAges 18–70 - NCT04440436RecruitingPhase 1/Phase 2
IM19 study for relapsed or refractory non-Hodgkin lymphoma
This trial tests whether IM19 can safely and effectively treat non-Hodgkin lymphoma that has come back or did not respond to prior treatment. It is for adults with certain lymphoma markers and good overall functioning.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04665674Recruiting
Study of adults with pulmonary Langerhans cell histiocytosis
This study follows adults with a specific lung condition to better understand how it behaves over time. If you have the right diagnosis, joining could help researchers learn what to expect and how to manage it.

Prediction tool for arm swelling after breast cancer surgery
This trial tests a prediction tool (a “nomogram”) to estimate who is at risk of developing breast cancer–related lymphedema, or long-term arm swelling, after surgery. If you fit the surgery and lymph node criteria, your information may help personalize follow-up and prevention.

Testing intermittent ibrutinib for advanced chronic lymphocytic leukemia
This trial studies whether taking ibrutinib in a less continuous (“intermittent”) schedule can keep your chronic lymphocytic leukemia (CLL) under control. It’s for people who have already received ibrutinib for at least 6 months and had a good early response, aiming to reduce treatment intensity while tracking safety and cancer control.
