Recruiting studies
- NCT05043571RecruitingPhase 1
CAR T-cell therapy for relapsed T-cell leukemia

SingaporeAges 6 months–65 years - NCT03094429RecruitingPhase 2/Phase 3
Testing NaBen add-on to clozapine for tough schizophrenia symptoms
This trial tests whether adding NaBen (a supplement-like medicine) to clozapine can improve “residual” symptoms in adults with difficult-to-treat schizophrenia. The study also checks safety and the best dose, using a placebo (inactive pill) for comparison.
Pasadena, CaliforniaAges 18–55 - NCT01566175Recruiting
Neovasc device trial for hard-to-treat chest pain
This trial tests a device called the Neovasc Coronary Sinus Reducer to help people with long-lasting, hard-to-control chest pain (angina) who cannot have artery-opening procedures. It may improve symptoms by changing blood flow in the heart’s vein system.

Study drug for B7-H3 positive neuroblastoma after relapse
This Phase 1 study tests TAA06, an injection that targets a marker called B7-H3 on neuroblastoma tumor cells. It is for children who have neuroblastoma that has come back or did not respond to prior treatment, aiming to see whether the treatment is safe and can shrink tumors.
Jinan, ShandongAges 1 year+ - NCT04606459Recruiting
Device trial for hard-to-treat heart chest pain from small vessels
This trial tests whether a small pressure-reducing device placed in a heart vein (the coronary sinus) can reduce symptoms in people with ongoing chest pain from tiny blood vessel problems. It is for angina that has not improved despite standard heart medicines, and only if special heart tests show reversible reduced blood flow.
Mainz, Rhineland-PalatinateAges 18–85 - NCT06125652RecruitingPhase 1/Phase 2

Stem cell transplant using half-matched donor and cyclophosphamide
This trial tests a stem cell transplant option for children or young adults with severe aplastic anemia that did not respond to prior immune-suppressing treatment. It uses a “half-matched” donor and gives post-transplant cyclophosphamide to help the donor cells work and reduce certain immune reactions.

This trial tests if adding a special radiofrequency treatment to the drugs Lonsurf (TAS-102) and Avastin (bevacizumab) can help people whose colorectal cancer has spread to the liver and has not responded to previous treatments. It is for patients with limited options who have already tried at least two standard chemotherapy regimens.

Cincinnati, OhioAges 1–20 - NCT06229340RecruitingPhase 2
Two drug combinations for advanced cancer with RAS mutations
This trial tests two different treatment combinations (leflunomide alone or with MEK inhibitor and hydroxychloroquine) in people with advanced cancer that has a RAS mutation and has not responded to at least two prior therapies.
Saint PetersburgAges 18–85 - NCT07855302RecruitingPhase 1
CAR T-cell therapy for young people with lupus
This trial tests a treatment that uses a patient's own immune cells, modified to target and calm the overactive immune system causing lupus. It is for young people whose lupus is active despite trying several standard treatments.
SeoulAges Up to 25 years - NCT06254560RecruitingPhase 2
Rituximab for severe aplastic anemia with platelet transfusion problems
This study tests if the drug rituximab can help people with severe aplastic anemia whose bodies have stopped responding to platelet transfusions. It aims to see if rituximab can improve the body's ability to accept platelets again.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT06418776RecruitingPhase 3
Comparing treatments for AML that returns or doesn't respond
This study compares two different treatments for people whose AML did not go away with initial therapy or came back early. It aims to find which approach works better.
MoscowAges 18 years+ - NCT07845942Recruiting
Donor stem cell transplant for stubborn systemic juvenile arthritis
This study tests a bone marrow transplant (using donor cells) to treat severe systemic juvenile idiopathic arthritis (sJIA) that has not responded to other treatments. The goal is to reset the immune system to stop the disease and its complications, like lung problems or recurrent macrophage activation syndrome.
Cincinnati, OhioAges Up to 35 years - NCT06443866Recruiting
I-124 PET/CT Imaging for Thyroid Cancer
This study uses a special type of PET/CT scan (I-124) to see where thyroid cancer is in your body and how much radiation it would get from radioactive iodine therapy. It helps doctors plan treatment for people whose cancer may not respond to standard radioactive iodine or who are being considered for targeted medicines.

Common questions
- Are there clinical trials for refractory?
- Yes. Clin2 currently lists 1,200 recruiting refractory 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 refractory 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 refractory 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.
