Donor-made memory T-cell therapy for hard-to-treat leukemia
This Phase 1 study tests an immune-cell therapy made from a matched donor to treat relapsed or refractory CD19-positive leukemia. It may help patients who have limited options, especially those who cannot receive the standard donor-cell or self-made (autologous) CD19 CAR T-cell therapy.
Memphis, TennesseeAges Up to 21 years - NCT04892277RecruitingPhase 1
CD19 CAR-T for adults with hard-to-treat B-cell cancers
This Phase 1 trial tests a lab-made immune therapy (CD19 CAR-T) for adults whose B-cell cancers have come back or did not respond to treatment. It may help your immune system better recognize and attack cancer cells, but it is early research, so benefits and risks are still being defined.
Rochester, MinnesotaAges 18 years+ - NCT04920617RecruitingPhase 2
Vaccine plus pembrolizumab, with or without low-dose chemo
This Phase 2 study tests whether a cancer vaccine called DPX-Survivac, along with pembrolizumab (an immune medicine), can help shrink diffuse large B-cell lymphoma (DLBCL) that has come back or not responded. It also looks at whether adding intermittent low-dose cyclophosphamide (a low-dose chemotherapy) improves results.
Fountain Valley, CaliforniaAges 18 years+ - NCT06742996RecruitingPhase 3
Sonrotoclax plus zanubrutinib for relapsed mantle cell lymphoma

Birmingham, AlabamaAges 18 years+ - NCT05053607Recruiting
Text and Fitbit monitoring during isatuximab treatment
This trial follows people with multiple myeloma who are getting isatuximab through a vein (IV). It tests how well real-world health tracking (text/app messages and Fitbit data) works during treatment, and whether it can help care teams understand your experience.

Trial of APG-2575 for returning or resistant CLL/SLL
This trial studies APG-2575 in people with CLL/SLL that has come back or is not responding to prior treatments. It may help shrink disease and improve control when standard options have stopped working.
Guangzhou, GuangdongAges 18 years+ - NCT05180097RecruitingPhase 2
Immunotherapy with stem cell transplant for relapsed Hodgkin lymphoma
This Phase 2 trial tests whether pembrolizumab plus brentuximab works better than standard chemotherapy followed by an autologous stem cell transplant for people whose classic Hodgkin lymphoma has come back or did not respond. It may help by improving cancer control before and around stem cell transplant and by comparing outcomes between the two treatment approaches.
Concord, New South WalesAges 18 years+ - NCT05211570RecruitingPhase 1/Phase 2
Study drug AB8939 for AML after prior treatments
This Phase 1/2 study tests AB8939 in people with acute myeloid leukemia (AML) whose disease has come back or did not respond to earlier treatment. It may help researchers find a safe dose and learn whether the treatment can control the leukemia.
Houston, TexasAges 18 years+ - NCT05237986Recruiting
Study brain and thinking effects after CAR T therapy in youth
This study looks at how CAR T-cell treatment affects thinking, learning, and day-to-day brain function in children and young adults with certain blood cancers. You (and a caregiver) may complete online testing so researchers can track these changes over time and whether support is needed.
Los Angeles, CaliforniaAges 5 years+ - NCT05249959RecruitingPhase 2
Loncastuximab after short treatment for relapsed mantle cell lymphoma
This Phase 2 trial studies whether adding loncastuximab after a short course of standard immunochemotherapy can better control mantle cell lymphoma that came back or didn’t respond. It specifically targets people who previously received a BTK inhibitor (or couldn’t tolerate it).
Brescia, ItalyAges 18–79 - NCT05263284RecruitingPhase 1
Study of 8-chloroadenosine plus venetoclax for relapsed or refractory AML
This trial tests a combination of two drugs, 8-chloroadenosine and venetoclax, for people with acute myeloid leukemia (AML) that has come back or not responded to prior treatments. The goal is to see if this combination can help control the leukemia.
Duarte, CaliforniaAges 18 years+ - NCT05271292RecruitingPhase 1/Phase 2
Chiauranib for advanced cancers that returned or won’t respond
This Phase 1/2 study tests chiauranib in people with advanced solid cancers (including small cell lung cancer) that have come back or no longer respond to standard treatments. It aims to find a safe dose and see whether the treatment can help shrink tumors.

Common questions
- Are there clinical trials for relapsed/refractory?
- Yes. Clin2 currently lists 417 recruiting relapsed/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 relapsed/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 relapsed/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.
