Recruiting studies
- NCT05292664RecruitingPhase 1
Venetoclax trial for high-risk blood cancers in young patients
This Phase 1 study tests venetoclax to treat certain high-risk blood cancers in children, teens, or young adults. It is designed to see if the drug can work safely for patients whose disease has returned or did not respond to prior treatment.
San Francisco, CaliforniaAges 1–40 - NCT05302037RecruitingPhase 1
CAR T cell therapy for advanced cancers that can be targeted
This early-phase study tests a lab-made immune cell treatment that is designed to find and attack tumors that show a specific target on cancer cells. It is for adults with advanced cancers that have not responded well to at least two standard treatments.
SingaporeAges 21 years+ - NCT05299424RecruitingPhase 1/Phase 2
CM336 for multiple myeloma after prior treatments
This trial tests CM336, a new medicine, in people with multiple myeloma that has returned (relapsed) or not responded (refractory) to standard treatments. It may help by trying a different approach when other key medicines have already been tried.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05305859RecruitingPhase 2
Venetoclax, chidamide, and azacitidine for hard-to-treat AML
This Phase 2 trial tests whether adding three medicines—venetoclax, chidamide, and azacitidine—can help adults whose AML has come back or did not respond to treatment. It may help shrink or control the leukemia and improve outcomes for people who fit the study’s health and lab requirements.
Xiamen, FujianAges 18 years+ - NCT05312255Recruiting
Non-drug help to improve quality of life in myeloma
This study tests non-chemotherapy supports meant to improve quality of life and immune health for people with multiple myeloma (or related conditions). Depending on the group, it may involve activities, nutrition, and/or a medication like a beta blocker.
Buffalo, New YorkAges 18 years+ - NCT05317403RecruitingPhase 1
Venetoclax plus chemo to change cancer cell behavior
This Phase 1 trial tests whether venetoclax, combined with chemotherapy and a “cancer cell behavior” medicine strategy, can improve treatment for people with AML that has come back or not gone into remission. It’s mainly looking at safety and early signs of benefit.
Milwaukee, WisconsinAges 1–25 - NCT05319314RecruitingPhase 1/Phase 2
Study drug for advanced colon cancer that has come back or failed
This Phase 1/2 trial tests LYL273, a new targeted treatment, for people with metastatic colorectal (colon) cancer that has returned or not responded to standard chemo. It’s designed to see how well the drug can control the cancer and what side effects it causes.
Duarte, CaliforniaAges 18 years+ - NCT05326243RecruitingPhase 1/Phase 2
CAR-T therapy for hard-to-treat B-cell lymphoma
This trial tests a CAR-T cell treatment made to target CD19 on lymphoma cells (PL001). It’s for people whose B-cell lymphoma has come back or not responded to standard treatments, aiming to shrink the cancer and help control the disease.
Taipei, TaiwanAges 14 years+ - NCT05334823RecruitingPhase 2
CAR T-cell treatment for CD19-positive relapsed leukemia in children
This Phase 2 trial tests pCAR-19B, a customized immune-cell treatment for children and teens with CD19-positive B-ALL that has come back or did not respond to standard therapy. If eligible, you would receive the cell infusion after cell collection and testing to make sure the leukemia cells have the right marker.
Beijing, Beijing MunicipalityAges 3–21 - NCT05336383RecruitingPhase 2
Radiation after prior CAR T for relapsed multiple myeloma
This trial tests giving “salvage” radiation (radiation meant to control remaining cancer) after you’ve already had BCMA CAR-T therapy for multiple myeloma. It’s for people whose PET or other scan still shows active myeloma at least 30 days after CAR-T, and who have a spot that radiation can target.
Houston, TexasAges 18 years+ - NCT05338931RecruitingPhase 1/Phase 2
AT101 for relapsed or refractory B-cell lymphoma patients
This trial studies AT101 to see how safe it is, what side effects it causes, and whether it can help people with B-cell non-Hodgkin lymphoma that has come back or did not respond to treatment. It may be an option if your usual treatments are no longer working or aren’t suitable for you.
SeoulAges 19 years+ - NCT05346068Recruiting
Compare two balloon types for calcium-heavy blocked heart arteries
This trial studies whether one type of balloon works better than another for treating badly calcified (hardened) coronary artery blockages. If you qualify, you would be randomly assigned to get the tested balloon treatment during your heart procedure.
LucerneAges 18 years+ - NCT05348213RecruitingPhase 2
Targeted drugs plus R-ICE chemo for relapsed lymphoma
This Phase 2 trial studies targeted drugs combined with R-ICE chemotherapy in people with diffuse large B-cell lymphoma (DLBCL) that has come back or hasn’t responded. It may help shrink the lymphoma after prior treatment.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05363111RecruitingPhase 1
Testing a targeted radioactive drug for relapsed myeloma
This Phase 1 study tests a targeted radioactive medicine made from daratumumab plus a radioactive payload, aiming to treat multiple myeloma that has come back or doesn’t respond to treatment. It’s designed mainly to check safety and how the treatment works in people who have had several prior therapies.
Duarte, CaliforniaAges 18 years+ - NCT05366179RecruitingPhase 1
Personalized CAR-T therapy for recurring brain tumor
This Phase 1 study tests a personalized immune-cell treatment (CAR-T) made from your own cells to attack a marker called B7-H3 on recurring glioblastoma. It may help shrink or control the tumor, but the main goal is to check safety and how the treatment works.
Chapel Hill, North CarolinaAges 18 years+ - NCT05372354RecruitingPhase 1/Phase 2
Testing a new multiple myeloma drug with other treatments
This early-phase study tests how safe a new drug (CC-92480) is and how much it stays in the body, when given with other standard or study treatments. It’s for people whose multiple myeloma has come back or did not respond after prior therapy, with the goal of improving disease control.
Birmingham, AlabamaAges 18 years+ - NCT05398003Recruiting
Stimulating nerves to treat long-lasting neck and arm pain
This trial tests whether a nerve-stimulation treatment can reduce chronic neck and upper arm pain when other treatments haven’t worked. It includes adults who can consent and attend follow-up visits, and it checks for safety with pregnancy prevention and a specific early test after implantation.

CAR-NK cell therapy for certain solid tumors
This early-phase trial tests a lab-made immune cell treatment for advanced solid tumors that show specific targets (including Claudin 6, GPC3, Mesothelin, or AXL). It may help the immune system better recognize and kill tumor cells, but eligibility depends on test results and your overall health.
Guangzhou, GuangdongAges 18–75 - NCT05417737Recruiting
Ozone therapy for chronic pain when standard treatments fail
This study offers a palliative (comfort-focused) ozone treatment to adults with chronic pain when usual treatments don’t work or are too risky. Researchers will check whether adding ozone can help symptoms and whether it’s safe for selected patients.

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.
