BeijingAges 18–75 - NCT03838042RecruitingPhase 1/Phase 2
Testing nivolumab plus entinostat for high-risk childhood cancers
This trial studies whether nivolumab (an immune therapy) plus entinostat (an epigenetic medicine) can help children and teens with high-risk cancers that have come back, worsened, or did not respond to prior treatment. It also looks at specific tumor “biomarkers” to group patients and guide how the study is run.
Randwick, New South WalesAges 2–21 - NCT06247501RecruitingPhase 2
CAR-T therapy for children with B-cell ALL needing transplant
This study tests a new type of immune-cell therapy (called CAR-T cells) for children and young adults with a specific blood cancer (B-cell ALL) who need a stem cell transplant. The treatment uses a patient's own T-cells that are modified to find and kill cancer cells with the CD19 marker.
SeoulAges Up to 25 years - NCT06287541Recruiting
Do you need a second bladder surgery after a negative urine test?
This study looks at whether a second bladder surgery is still needed for people with high-risk bladder cancer who had a negative urine test after their first surgery.
Nanjing, JiangsuAges 18 years+ - NCT04243785RecruitingPhase 1
Testing BTX-A51 for hard-to-treat AML or high-risk MDS
This Phase 1 study tests BTX-A51 in adults with relapsed or refractory acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). It’s designed to see if the treatment can be given safely and to learn how it works in people whose standard treatments have not helped or are no longer an option.
Duarte, CaliforniaAges 18 years+ - NCT06280508RecruitingPhase 2
Perioperative chemo plus immunotherapy for bile duct cancer
This trial tests a combination of chemotherapy, immunotherapy (adebrelimab), and a targeted therapy (apatinib) before and after surgery for bile duct cancer that can be removed and has a high risk of coming back. It aims to see if this approach can lower the chance of recurrence.
Guangzhou, China/GuangdongAges 18 years+ - NCT06404697RecruitingPhase 2
Extra radiation to lymph nodes above collarbone for high-risk breast cancer
This trial tests giving a focused, higher dose of radiation to the lymph nodes above the collarbone after breast cancer treatment. It is for patients whose cancer did not fully disappear from those nodes after pre-surgery chemotherapy, to see if extra radiation can help prevent recurrence.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06407947RecruitingEarly Phase 1
CT071 for high-risk newly diagnosed multiple myeloma
This trial tests an experimental therapy called CT071 for people with newly diagnosed, high-risk multiple myeloma. It aims to see if this treatment can help control the disease in people who have certain aggressive features.

Low-dose ticagrelor vs aspirin after heart stent placement
This study compares ticagrelor taken at a lower dose versus regular aspirin to help prevent future heart attacks in people who recently had a stent placed after acute coronary syndrome. You may qualify if you’re considered “high risk” for new blockages or clots and can take dual anti-platelet therapy for 12 months.

Common questions
- Are there clinical trials for clinical high risk?
- Yes. Clin2 currently lists 552 recruiting clinical high risk studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a clinical high risk trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a clinical high risk trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
