Recruiting studies
- NCT05457829RecruitingPhase 2
Testing two chemotherapy combinations for relapsed pediatric rhabdomyosarcoma
This trial compares two treatment combinations—liposomal doxorubicin plus irinotecan versus a different chemotherapy plan—in children and teens whose rhabdomyosarcoma came back or did not respond. It aims to see which option works better and is safer for children who have had prior cancer treatment.
GuangzhouAges 6 months–18 years - NCT05468359RecruitingPhase 1/Phase 2
Testing four medicines in children and teens with hard-to-treat tumors
This early-phase trial studies how safe and effective a combination of four medicines is for children and teens with certain solid tumors that have come back or cannot be controlled with standard treatment. It may help by improving tumor control, while also carefully tracking side effects.
Germantown, TennesseeAges Up to 30 years - NCT05476770RecruitingPhase 1
Tagraxofusp for children with CD123-positive leukemia
This study tests tagraxofusp, a medicine that targets a marker called CD123 on cancer cells, in children and young adults whose leukemia or lymphoma has come back or is resistant to treatment. It may help by shrinking the cancer and improving disease control after standard therapies have not worked.

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.
Edegem, AntwerpAges 18 years+ - NCT05504772Recruiting
Personalized genetic testing for children with cancer
This trial studies how personalized (tailored) genetic testing can help guide care for children with cancer. It may help match treatment choices to each child’s genetic risk, and it includes optional return of germline (inherited) test results.
AdelaideAges birth–25 years - NCT05512390RecruitingPhase 1
Test drug ABBV-319 in B-cell blood cancers
This Phase 1 trial studies ABBV-319 given by vein to see what side effects it causes and how the cancer activity changes in certain B-cell blood cancers. It may help people with relapsed or treatment-resistant disease by exploring new treatment options and better understanding how the drug moves through the body.

Testing pirtobrutinib plus venetoclax for relapsed mantle cell lymphoma
This Phase 2 trial tests how well the combination of pirtobrutinib and venetoclax works for people with mantle cell lymphoma that has come back or did not respond to treatment. It’s meant to help shrink the lymphoma and improve outcomes after prior therapies.
Houston, TexasAges 18 years+ - NCT05530421RecruitingPhase 2
Selinexor and Venetoclax with Dexamethasone for Myeloma
This trial studies a combination of selinexor, venetoclax, and dexamethasone to treat multiple myeloma that has returned or is resistant to prior treatments. It may help shrink the myeloma and improve disease control in people with a specific myeloma genetic marker (t(11;14)).

This trial is a real-world registry that follows people with Parkinson’s who are planning to get an Exablate 4000 procedure (a focused ultrasound treatment) for one-sided symptoms that are difficult to control with medication. It mainly checks outcomes and safety over time, helping doctors understand how well this treatment works in everyday care.
Baltimore, MarylandAges 30–99 - NCT05546580RecruitingPhase 1
Testing iadademstat plus gilteritinib for relapsed AML with FLT3 mutation
This Phase 1 study tests whether a new drug called iadademstat, combined with gilteritinib, can help people with relapsed or refractory AML that has certain FLT3 mutations. It’s mainly looking to find a safe dose and see early signs of effectiveness.
Gilbert, ArizonaAges 18 years+ - NCT05562830RecruitingPhase 1/Phase 2
Study for bladder or urinary tract cancer after PD-1 failure
This Phase 1/2 study tests investigational cancer treatment(s) in people with locally advanced or metastatic urothelial cancer that has not responded to PD-1/PD-L1 immunotherapy. It may help by trying a new approach after prior checkpoint treatment has stopped working or the cancer returns.
Orange, CaliforniaAges 18 years+ - NCT05579366RecruitingPhase 1/Phase 2
Study drug for advanced ovarian and other solid cancers
This Phase 1/2 trial studies Rinatabart Sesutecan to treat advanced cancers, with special focus on certain ovarian cancer types. It’s meant for people whose cancer has come back or has not responded to prior treatments.
Phoenix, ArizonaAges 18 years+ - NCT05580601RecruitingPhase 1/Phase 2
Immunotherapy trial for children with relapsed or stubborn AML
This Phase 1/2 trial tests a lab-made immune-cell treatment (NK cells) for children with acute myeloid leukemia (AML) that has come back or did not respond to treatment. It aims to help the immune system attack leukemia cells in the bone marrow, especially when standard treatments have not worked.
Cincinnati, OhioAges 2 years+ - NCT05588648RecruitingPhase 1/Phase 2
Testing vactosertib for osteosarcoma that keeps coming back
This Phase 1/2 study tests how safe and how well vactosertib works for adolescents and adults with osteosarcoma that has returned, stopped responding, or is getting worse despite prior treatment. You may be able to join if you meet age, cancer, recovery-from-prior-therapy, and health-test requirements.
Cleveland, OhioAges 12 years+ - NCT05595447RecruitingPhase 2/Phase 3
Testing new treatment for Hodgkin lymphoma that came back
This study tests a treatment plan for adults with Hodgkin lymphoma that has returned or did not respond to ABVD chemotherapy. It may help people with a higher-risk pattern of disease, as long as their organ function and overall health meet study limits.
León, GuanajuatoAges 15–90 - NCT05597306RecruitingPhase 1
Venetoclax plus bomedemstat for relapsed or hard-to-treat AML
This early-phase study tests venetoclax together with bomedemstat in adults whose acute myeloid leukemia (AML) has come back or did not respond to standard treatment. The goal is to see whether this combination can control the leukemia safely and help shrink it enough to improve outcomes.

Study of a new drug for hard-to-treat AML or high-risk MDS
This early study tests a new medicine (ABD-3001) to see if it’s safe and tolerable, how the body handles it, and whether it shows early signs of helping people with relapsed or hard-to-treat AML or high-risk MDS. It may be an option if standard treatments have already failed and you can’t receive a stem cell transplant.

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.
