Recruiting studies
- NCT05826535RecruitingPhase 1/Phase 2
Test of CAR T-cell therapy for aggressive B-cell lymphoma
This Phase 1/2 study tests a lab-made immune cell treatment (CAR T cells) made from your own blood cells to treat aggressive large B-cell lymphoma that has come back or didn’t respond. If you qualify, the goal is to see whether this treatment is safe and can shrink lymphoma.
Irvine, CaliforniaAges 18 years+ - NCT05830123RecruitingPhase 2
Test drug HS-20093 for osteosarcoma after earlier treatment
This Phase 2 trial studies HS-20093 in adults with osteosarcoma or other sarcomas that came back or did not respond to standard treatment. It aims to see how well the drug works and whether it is safe for people whose cancer has progressed.
BeijingAges 18 years+ - NCT05833763RecruitingPhase 2
Glosfitamab plus pirtobrutinib for mantle cell lymphoma after BTK drugs
This Phase 2 trial tests how well two anti-cancer medicines—glofitamab and pirtobrutinib—work for mantle cell lymphoma (MCL) that has not responded well to prior BTK inhibitor therapy. It may help by shrinking the lymphoma after earlier treatment and checking how safe the combination is for people with similar disease history.
Parkville, VictoriaAges 18 years+ - NCT05839418Recruiting
Registry study for people with status epilepticus
This study records information about people who are in the hospital with status epilepticus (prolonged seizure activity) to better understand care for refractory cases. If you qualify, your team may collect your clinical details during your hospital stay rather than giving a new treatment as part of the study.
LinzAges 18 years+ - NCT05842707RecruitingPhase 1/Phase 2
Cord blood CAR cells for hard-to-treat B-cell lymphoma
This Phase 1/2 study tests cord blood–derived CAR NK cells that are designed to attack lymphoma cells marked with CD19 and/or CD70. It is for people whose B-cell non-Hodgkin lymphoma has come back or did not respond to prior treatment, including CAR-T when applicable.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05845255Recruiting
Test wearable monitoring for epilepsy quality of life and safety
This study tests a wearable device that records seizure-related information to understand how epilepsy affects daily life and safety. It may help your care team better track seizures in real-world settings and understand quality-of-life changes.
KorkAges 12–65 - NCT05846763Recruiting
Obinutuzumab plus lenalidomide for returning follicular lymphoma
This study looks at giving obinutuzumab together with lenalidomide to adults whose follicular lymphoma has come back or did not respond well to prior treatment. It may help control the cancer after relapse or resistance to standard therapies.
TianjinAges 18 years+ - NCT05846750RecruitingPhase 2
Obinutuzumab plus lenalidomide for relapsed marginal zone lymphoma
This trial studies whether obinutuzumab combined with lenalidomide can control marginal zone lymphoma that has come back or not responded to prior treatment. If you qualify, you may receive these medicines together to help shrink tumors and improve symptoms.
Tianjin, TianAges 18 years+ - NCT05848765RecruitingPhase 2
Trial for relapsed follicular lymphoma after prior chemo
This Phase 2 trial studies treatment options for follicular lymphoma that has returned or did not respond to prior therapy. It compares a standard chemotherapy approach against another study treatment to see which works better and is tolerable.
AberdeenAges 18 years+ - NCT05853965RecruitingPhase 1/Phase 2
Study of belantamab plus venetoclax for relapsed myeloma
This Phase 1/2 trial tests whether combining belantamab mafodotin with venetoclax can treat multiple myeloma that has come back or did not respond (relapsed/refractory). It focuses on a specific myeloma subtype with a t(11;14) genetic marker, aiming to reduce the cancer in people who have already had several treatments.
Hamburg, HamAges 18 years+ - NCT05856981RecruitingPhase 1
Testing ADU-1805 for advanced solid tumors safety
This early study tests whether ADU-1805 is safe in people with advanced solid tumors and checks how the body processes the drug. Depending on your cancer type, it may also be looking specifically at certain cancers that have not yet received PD-(L)1 immunotherapy.
Detroit, MichiganAges 18 years+ - NCT05859074RecruitingPhase 1
Testing MQ710 injections alone or with pembrolizumab for advanced cancers
This early-phase study tests MQ710, a medicine given by injection into a reachable tumor, to see how well it can control advanced cancers. Some participants also receive pembrolizumab, an immunotherapy, to help the immune system fight the cancer.
Basking Ridge, New JerseyAges 18 years+ - NCT05868395RecruitingPhase 2
Treating relapsed mantle cell lymphoma with three drug combination
This Phase 2 study tests how well polatuzumab combined with bendamustine and rituximab works for mantle cell lymphoma that has come back or not responded. It may help shrink tumors and improve disease control, especially after prior treatment with ibrutinib.
ViennaAges 18–100 - NCT05876000Recruiting
Heart pump study for very severe heart failure
This trial tests a left ventricular assist system (a mechanical heart pump for the left side of the heart) in people with very severe heart failure. It may help people who are too sick or not improving despite best available medical treatment.
GrazAges 18–75 - NCT05890352RecruitingPhase 2
Add new medicines to standard treatment for returning lymphoma
This Phase 2 study tests whether adding tafasitamab, lenalidomide, tazemetostat, and zanubrutinib (along with standard lymphoma treatment) can improve outcomes in people whose large B-cell lymphoma has returned or not responded. It may help control disease more effectively and improve response duration for eligible patients.
Tucson, ArizonaAges 18 years+ - NCT05892718RecruitingPhase 1
Testing an immune drug for hard-to-treat cancers
This early-phase study tests HCB101, an immune-targeting drug, to see if it is safe and can shrink certain solid tumors or non-Hodgkin lymphoma. It may help people whose cancer has returned or stopped responding to standard treatments.
Port Saint Lucie, FloridaAges 18 years+ - NCT05896228RecruitingPhase 2
Combination therapy for relapsed multiple myeloma to target MRD
This Phase 2 trial tests iberdomide plus daratumumab, carfilzomib, and dexamethasone in people whose multiple myeloma has come back or not responded. The goal is to increase how often patients reach “MRD-negative” status, meaning very small amounts of cancer cells are not detectable, which may help improve outcomes.
Miami, FloridaAges 18–75 - NCT05922501RecruitingPhase 2
Test four medicines for relapsed multiple myeloma
This Phase 2 study tests a combination of medicines (isatuximab, belantamab mafodotin, pomalidomide, and dexamethasone) for multiple myeloma that has come back or did not respond to prior treatment. It may help by better controlling the myeloma after standard therapies have failed.
Boston, MassachusettsAges 18 years+ - NCT05949125RecruitingPhase 1
CD123-positive AML trial testing an immune cell treatment
This Phase 1 trial tests an allogeneic immune-cell therapy for adults with CD123-positive acute myeloid leukemia (AML) that has not responded well to standard treatments. It aims to see whether this treatment can control leukemia after medicines and possibly transplant options are no longer suitable.
Ulm, Baden-WurttembergAges 18 years+ - NCT05950165RecruitingPhase 1/Phase 2
Study of CHO-H01 for certain relapsed lymphoma, alone or with lenalidomide
This trial tests CHO-H01 (an anti-cancer medicine targeting CD20) to see if it is safe and effective in people with relapsed or refractory non-Hodgkin’s lymphoma. In one part of the study it may be used alone, and in another part it may be combined with lenalidomide to improve results.

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.
