Duarte, CaliforniaAges 18 years+ - NCT04545762RecruitingPhase 1
Anti-CD19 CAR-T for certain relapsed lymphoma
This Phase 1 study tests an anti-CD19 CAR-T cell treatment in adults with specific types of relapsed or treatment-resistant non-Hodgkin lymphoma. It may help by finding and attacking lymphoma cells that carry the CD19 marker, but it’s early-stage and eligibility is strict.
San Francisco, CaliforniaAges 18 years+ - 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 - NCT04657861RecruitingEarly Phase 1
BCMA/TACI CAR-T for relapsed or refractory multiple myeloma
This early-phase study tests a CAR-T cell treatment made to target BCMA and TACI proteins in multiple myeloma. It may help people whose myeloma has come back or did not respond to prior treatments, especially after certain prior therapies.

CNCT19 cell therapy for relapsed or refractory ALL
This Phase 2 study tests an infusion of modified immune cells (CNCT19) in people with acute lymphoblastic leukemia (ALL) that has come back or did not respond to treatment. It may help by targeting leukemia cells that have a specific marker called CD19.
Beijing, Beijing MunicipalityAges 18–65 - NCT04744116RecruitingEarly Phase 1
Cord blood cell therapy added to ruxolitinib for steroid-resistant GVHD
This trial studies whether adding cord-blood–derived cells to ruxolitinib can improve steroid-resistant acute graft-versus-host disease (GVHD) affecting the lower gut or liver. It’s meant for people who are not getting better (or are worsening) despite adequate steroid treatment.
Houston, TexasAges 12–80 - NCT04774393RecruitingPhase 1/Phase 2
Study for AML after it returns or resists treatment
This Phase 1/2 trial tests a combination of medicines (decitabine/cedazuridine, venetoclax, and ivosidenib or enasidenib) in people with acute myeloid leukemia (AML) that has come back or hasn’t responded. It may help control the leukemia by targeting cancer cells and specific genetic changes in the leukemia.
Houston, TexasAges 18 years+ - NCT04871607RecruitingPhase 2
Yttrium antibody plus chemotherapy for hard-to-treat Hodgkin lymphoma
This trial studies a targeted antibody therapy with yttrium, combined with intensive chemotherapy, for adults whose Hodgkin lymphoma did not respond well or came back. It may help by delivering cancer-killing radiation directly to lymphoma cells and preparing the body for treatment after transplant conditioning.
Duarte, CaliforniaAges 18 years+ - NCT04921527RecruitingPhase 3
Chiauranib with weekly paclitaxel for tough ovarian cancer
This Phase 3 trial tests whether chiauranib combined with weekly paclitaxel can shrink recurrent ovarian, fallopian tube, or primary peritoneal cancer that did not respond to platinum chemotherapy. It is designed for people who have limited treatment options after platinum-resistant or platinum-refractory disease.
Shanghai, ChinaAges 18–70 - NCT04989621RecruitingPhase 2
Orelabrutinib plus rituximab for relapsed follicular lymphoma
This Phase 2 study tests whether orelabrutinib combined with rituximab, followed by orelabrutinib alone for a while, can control follicular lymphoma that has come back or did not respond. It may help shrink tumors and keep the disease from worsening after initial response.
Guangzhou, GuangdongAges 18 years+ - NCT05010122RecruitingPhase 1/Phase 2
Testing venetoclax and gilteritinib with ASTX727 for FLT3 leukemia
This Phase 1/2 trial tests a combination of medicines (ASTX727, venetoclax, and gilteritinib) for adults with FLT3-mutated acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS).

Common questions
- Are there clinical trials for refractory?
- Yes. Clin2 currently lists 1,208 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.
