CAR T-cell treatment for hard-to-treat childhood tumors
This Phase 1 study tests an experimental CAR T-cell treatment that targets GD2, with added immune-boosting and safety features, for children with relapsed or refractory neuroblastoma or osteosarcoma. It’s designed to see if the treatment is safe and can shrink these cancers when standard therapy hasn’t worked.
Atlanta, GeorgiaAges 1.5 years+ - NCT07014449RecruitingPhase 1
WBC100 capsule for relapsed or refractory AML
This trial tests an experimental capsule called WBC100 for people whose leukemia has come back or hasn't responded to standard treatments. It aims to see if the drug is safe and if it can help control the disease.
Hangzhou, ZhejiangAges 18 years+ - NCT07297667RecruitingPhase 1
CAR T-cell therapy for certain advanced solid tumors
This trial tests a new treatment called GCAR1, which uses your own immune cells (T-cells) to find and attack cancer cells that have a specific marker called GPNMB. It is for people with certain advanced solid tumors that have not responded to other treatments. The goal is to see if this therapy can help shrink or control the tumor.
Calgary, AlbertaAges 15 years+ - NCT05986240RecruitingPhase 1
Danvatirsen plus venetoclax for advanced blood cancers
This trial tests a new drug called danvatirsen, first alone and then with venetoclax, for people with advanced acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) that have not responded to standard treatments. The goal is to see if this combination can help shrink or control the cancer.
The Bronx, New YorkAges 18 years+ - NCT05633615RecruitingPhase 2
Testing new drug options after CAR T for aggressive lymphoma
This Phase 2 study tests whether adding or switching drug treatments after CAR T-cell therapy can improve outcomes for people with certain aggressive lymphomas that have come back or did not respond. It mainly looks at who remains disease-stable/partly improved after CAR T and what treatment approach works best next.
Tucson, ArizonaAges 18 years+ - NCT05947851RecruitingPhase 3
Nemtabrutinib plus venetoclax versus standard add-on therapy
This Phase 3 study tests whether adding nemtabrutinib to venetoclax works better than the usual next treatment approach (venetoclax plus rituximab) in people with relapsed or treatment-resistant CLL/SLL. It may help by improving how well the cancer responds after at least one prior therapy.
Springdale, ArkansasAges 18 years+ - NCT07200089RecruitingPhase 1
IL-7 treatment after CAR-T therapy for multiple myeloma
This trial tests whether a drug called NT-I7 (a lab-made immune booster) can help people with multiple myeloma who have already received a CAR-T cell therapy called cilta-cel. It's for patients whose myeloma has come back or hasn't responded well to treatment.
St Louis, MissouriAges 18 years+ - NCT06919939RecruitingPhase 2
Epcoritamab and Loncastuximab for relapsed large B-cell lymphoma
This trial tests a combination of two targeted drugs (epcoritamab and loncastuximab tesirine) for people with large B-cell lymphoma that has come back or not responded to prior treatment. The goal is to see if this combination can shrink tumors and improve outcomes.
Miami, FloridaAges 18 years+ - NCT04167696RecruitingPhase 1
Dose-finding drug study for AML or MDS after standard options fail
This Phase 1 trial tests CYAD-02 to find the safest and recommended dose for people with AML or MDS that has returned or did not respond to prior treatment. It may help if you have limited treatment options, but participation also requires meeting specific heart, lung, and lab safety requirements.

Venetoclax plus leukemia drugs for AML after treatment failure
This Phase 1 trial studies whether a combination of venetoclax (ABT-199) and “purine analogues” can help adults with AML that has come back or didn’t respond to earlier treatment. It’s designed to test safety and early effectiveness in people who haven’t previously developed resistance to venetoclax.

Common questions
- Are there clinical trials for relapsed/refractory?
- Yes. Clin2 currently lists 411 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.
