Ovarian cancer genetics: comparing platinum response groups
This study looks at genetic and other factors that may explain why some people with ovarian cancer respond well to platinum-based chemotherapy for many years, while others do not respond at all. The goal is to better understand these differences to improve future treatments.

Fecal transplant for steroid-resistant gut GVHD
This study tests if a fecal transplant (transferring healthy bacteria from a donor's stool into your gut) can help people with severe gut graft-versus-host disease that hasn't responded to steroids. It's for patients who have had a stem cell transplant and now have ongoing, severe gut symptoms.
TaoyuanAges Any age - NCT07366658RecruitingPhase 1
Experimental therapy for neuroendocrine tumors that did not respond to treatment
This trial tests an experimental therapy (NEUK203-13) for people with neuroendocrine tumors, including small cell lung cancer, that have not responded to or stopped responding to standard treatments. It aims to see if the drug is safe and to look for early signs that it might shrink tumors, especially in people whose tumors have a specific marker called DLL3.
BeijingAges 18–75 - NCT07368270RecruitingPhase 1
Anti-PD1 armored CAR-T cells for adults with relapsed/refractory DLBCL
This trial tests a new kind of cell therapy that combines CAR-T cells (which find and kill cancer cells) with an anti-PD1 'armor' to boost their power. It is for adults with diffuse large B-cell lymphoma (DLBCL) that has come back or not responded to earlier treatments.
SuzhouAges 18 years+ - NCT07369492RecruitingPhase 1
Study of BAFF-R CAR-T cells for CD19-negative B-cell lymphoma
This trial tests a new type of immunotherapy called BAFF-R CAR-T cells for people with B-cell lymphoma that has come back or not responded to treatment, and whose cancer cells do not have the CD19 protein. The treatment uses your own immune cells, modified to target and kill the lymphoma cells.
SuzhouAges 18 years+ - NCT07375563RecruitingPhase 3
Chemoimmunotherapy with NK cells for high-risk neuroblastoma
This trial tests a combination of chemotherapy, immunotherapy, and natural killer (NK) cell therapy for children with high-risk neuroblastoma or ganglioneuroblastoma that has not responded to initial treatment or has come back after treatment. The goal is to see if this approach can help destroy cancer cells more effectively.
MoscowAges 1.5 years–18 years - NCT07377435RecruitingPhase 1
Vaccine after CAR-T therapy for multiple myeloma
This trial tests whether a personalized vaccine (DC/MM fusion) given after standard CAR-T cell therapy can help prevent the cancer from coming back. It is for people with multiple myeloma that has returned or not responded to treatment.

Common questions
- Are there clinical trials for refractory?
- Yes. Clin2 currently lists 1,203 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.
