Recruiting studies
- NCT03676504RecruitingPhase 1/Phase 2
CAR T cell therapy for relapsed CD19 blood cancers
This trial tests a type of personalized immune treatment (CD19 CAR T cells made from your T cells) for adults (and children with ALL) whose CD19-positive blood cancer has come back or didn’t respond. It may help your immune system recognize and attack cancer cells that still have CD19.
HeidelbergAges 3 years+ - NCT07796516RecruitingPhase 2
Telitacicept for difficult-to-treat rheumatoid arthritis
This trial tests if a new medication, telitacicept, is safe and effective for people with difficult-to-treat rheumatoid arthritis. It may be an option for patients who have not found relief from other treatments.
Hefei, AnhuiAges 18 years+ - NCT07794514Recruiting
Comparing two drugs for liver graft-versus-host disease
This trial compares two medications, belumosudil and ruxolitinib, to see which one works better for a type of graft-versus-host disease (GVHD) that affects the liver after a stem cell transplant. GVHD happens when donor cells attack the patient's body, and this study focuses on patients whose liver GVHD has not improved with steroids or has gotten worse. The study aims to find a more effective treatment to control this condition.
Hangzhou, ZhejiangAges 12 years+ - NCT07799948Recruiting

Hanzhou, ZhejiangAges 18–75 - NCT06541327Recruiting
Cell therapy for returning lymphoma study
This study collects data from adults with lymphoma that has come back or not improved after treatment, who have received or are receiving special cell therapies. The goal is to learn more about how these treatments work in real life.
ShanghaiAges 18 years+ - NCT06479356RecruitingPhase 2
CAR T-cell therapy for relapsed large B-cell lymphoma
This trial tests an experimental CAR T-cell therapy for people with large B-cell lymphoma that has come back or not responded to at least two prior treatments. The therapy uses a patient's own immune cells, modified to find and attack cancer cells.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT06563986RecruitingPhase 2
Combination therapy for advanced colorectal cancer in the liver
This trial tests a combination of two chemotherapy drugs (FTD and tipiracil), a targeted therapy (bevacizumab), and a radiation treatment (radioembolization) for people with colorectal cancer that has spread mainly to the liver and hasn't responded to other treatments. The goal is to see if this combination can shrink tumors and help control the cancer.

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.
