Pomalidomide after CAR T for B-cell cancer
This trial tests whether the drug pomalidomide, given as a pill, can help people with B-cell leukemia or lymphoma who have recently received CAR T-cell therapy. The goal is to see if pomalidomide can keep the cancer from coming back, and it may be an option for those whose cancer is not growing but still needs management.
Ann Arbor, MichiganAges 18 years+ - NCT05053971RecruitingPhase 1/Phase 2
Entinostat plus ZEN003694 for advanced solid tumors
This Phase 1/2 study tests a new combination anti-cancer treatment (entinostat plus ZEN003694) in people with advanced solid tumors that can’t be controlled with standard care. It aims to find a safe dose and see whether the treatment can shrink tumors or control the disease.

Astatine-211 treatment before stem cell transplant for high-risk blood cancers
This trial tests a targeted radiation drug (Astatine-211) given before a donor stem cell transplant for people with high-risk leukemia or certain bone-marrow cancers. The goal is to better control the cancer before the transplant.

Emavusertib for recurrent brain lymphoma after prior treatment
This Phase 1/2 trial tests emavusertib (a targeted medicine) in adults with primary central nervous system lymphoma that has come back or not responded to treatment. It’s designed to find safe dosing and see how well the treatment can control the lymphoma in the brain/spinal fluid.
Phoenix, ArizonaAges 18 years+ - NCT03418038RecruitingPhase 2
Vitamin C with chemotherapy for certain relapsed blood cancers
This Phase 2 trial tests whether intravenous vitamin C (ascorbic acid) added to chemotherapy can improve outcomes for people with certain relapsed or treatment-resistant lymphomas or chronic myelomonocytic leukemia (CMML). It may help by boosting chemotherapy’s effectiveness and/or changing how the cancer responds.
Mankato, MinnesotaAges 18 years+ - NCT03630991RecruitingPhase 1
Calcium chelator medicine for AML or MDS during chemotherapy
This Phase 1 study tests whether edetate calcium disodium (also called succimer) can be safely given to people with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) while they are on chemotherapy. The goal is to learn the safest dose and whether it has signs of helping the blood cancer respond to treatment.
Houston, TexasAges 1 year+ - NCT03896269RecruitingPhase 1
CPX-351 for high-risk MDS or CMML that came back
This Phase 1 trial studies CPX-351, a cancer medicine, in people with high-risk myelodysplastic syndrome (MDS) or chronic myelomonocytic leukemia (CMML) whose disease relapsed or did not respond to prior treatment. It may help shrink or control the leukemia and improve blood counts in patients who cannot or do not want a stem cell transplant.
Houston, TexasAges 18 years+ - NCT04047641RecruitingPhase 1/Phase 2
Quizartinib with chemotherapy for new or returning leukemia
This trial tests a combination of anti-leukemia drugs (including quizartinib) together with chemotherapy for people with acute myeloid leukemia (AML), a rare mixed-type leukemia, or high-risk myelodysplastic syndrome (MDS). It may help by trying to better control cancer in people whose disease is newly diagnosed or has returned/not responded to prior treatment.
Houston, TexasAges 18 years+ - NCT04140487RecruitingPhase 1/Phase 2
Study drugs for certain FLT3-mutated blood cancers that have returned
This trial tests a combination of three medicines—azacitidine, venetoclax, and gilteritinib—in people with specific gene changes (FLT3 mutations) in leukemia and related bone marrow diseases that have come back or are hard to treat. The goal is to see if this drug combination can control the disease and improve outcomes.
Houston, TexasAges 18 years+ - NCT04414475RecruitingPhase 2
Selinexor plus low-dose steroid for hard-to-treat myeloma
This Phase 2 trial tests selinexor (a targeted anti-cancer medicine) plus low-dose dexamethasone to treat multiple myeloma that has not responded to many prior treatments. It compares selinexor combinations depending on what medicines you’ve already had, aiming to reduce myeloma activity and improve outcomes.
Pátrai, AchaiaAges 18 years+ - NCT04848064RecruitingPhase 1
Natural killer cells plus mogamulizumab for skin lymphoma
This early-phase study tests a combination of “natural killer” immune cells and a medicine called mogamulizumab to treat certain skin lymphomas that have come back or did not respond. It may help your immune system better find and attack cancer cells.
Columbus, OhioAges 18 years+ - NCT04941716RecruitingPhase 2
Acalabrutinib plus venetoclax for hard-to-treat CLL/SLL
This Phase 2 trial studies whether combining acalabrutinib and venetoclax can shrink or control chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has come back or did not respond to prior treatment. It may help by attacking the cancer using two different medicines together.
Seattle, WashingtonAges 18 years+ - NCT05054257RecruitingPhase 1
CAR T19 for hard-to-treat blood cancers that have CD19
This Phase 1 study tests CAR T cells designed to attack cancer cells that carry a marker called CD19. It’s for adults with certain relapsed or treatment-resistant B-cell leukemias (ALL) or lymphomas (NHL) where other treatments may not have worked.
PragueAges 18–80 - NCT05400603RecruitingPhase 1
Immunotherapy trial for relapsed neuroblastoma or osteosarcoma
This Phase 1 study tests lab-made donor immune cells (gamma delta T cells) plus chemotherapy to treat neuroblastoma or osteosarcoma that has come back or hasn’t responded to standard treatment. It’s designed to find a safe way to give this treatment and to see how well it might work.
Atlanta, GeorgiaAges 1 year+ - NCT05549661RecruitingPhase 1
Onvansertib for hard-to-treat CMML and MDS/MPN
This Phase 1 study tests onvansertib to see if it can help people with repeat or treatment-resistant chronic myelomonocytic leukemia (CMML) and MDS/MPN overlap. It also studies side effects and gathers blood/bone marrow samples to better understand how the treatment works.
Rochester, MinnesotaAges 18 years+ - NCT05658640RecruitingPhase 1/Phase 2
Testing trametinib and steroid plus chemo for relapsed blood cancers
This early-phase trial tests whether adding trametinib and dexamethasone to standard chemotherapy can improve outcomes for children whose blood cancer has come back or did not respond. Because it is a Phase 1/2 study, the main goal is to see safety and learn the best way to treat your specific cancer type.
ViennaAges 1–21 - NCT05711849RecruitingPhase 2
Stem cell treatment for long-lasting chest pain not helped by meds
This Phase 2 trial tests whether stem cells placed into the heart artery can safely reduce symptoms in people with “refractory” angina (chest pain) despite maximum heart-healthy medication. You may qualify if your chest pain is limiting your activity and other heart procedures (stents/bypass) aren’t possible or are too risky.
London, EnglandAges 18 years+ - NCT05745714RecruitingPhase 1/Phase 2
Targeted triple-combination treatment for children with relapsed blood cancers
This Phase 1/2 study tests a multi-drug combination (ruxolitinib, venetoclax, dexamethasone, plus chemotherapy) for children whose blood cancer has come back or did not respond. It aims to reduce the cancer by targeting specific genetic changes and may offer a new option when standard treatments have not worked.
ViennaAges 1–21 - NCT05751044RecruitingPhase 1/Phase 2
Study of four medicines for children with difficult blood cancers
This Phase 1/2 trial tests a combination of medicines (dasatinib, venetoclax, dexamethasone, cyclophosphamide, and cytarabine) in children and teens whose blood cancer has come back or did not respond to treatment. It aims to see whether this approach can control the cancer while checking what doses are safe.

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.
