It uses a “half-matched” donor and gives post-transplant cyclophosphamide to help the donor cells work and reduce certain immune reactions.
AmiensAges 3–35 - NCT05241093RecruitingPhase 2
HYML-122 plus cytarabine for FLT3-positive relapsed AML
This trial studies HYML-122 together with cytarabine to treat adults with FLT3-positive acute myeloid leukemia (AML) that has come back or did not respond to prior treatment. It may help shrink the leukemia and improve blood-count recovery when standard treatments haven’t worked.
Suzhou, JiangsuAges 18 years+ - NCT05241106RecruitingPhase 2
HYML-122 for FLT3-mutated AML that came back or did not respond
This Phase 2 trial studies HYML-122 in adults with acute myeloid leukemia (AML) that has either come back or did not respond to prior treatment. It targets tumors with an FLT3 mutation and may offer a new treatment option if your AML is resistant or relapsed.
Suzhou, JiangsuAges 18 years+ - NCT05300282RecruitingPhase 1/Phase 2
Atezolizumab plus chemotherapy for Hodgkin lymphoma after relapse
This trial studies whether adding atezolizumab to a chemotherapy-type treatment (the BEGEV regimen) can shrink Hodgkin lymphoma that has come back or did not respond. It may help people who have only had one prior whole-system (systemic) treatment and can still receive stem cell transplant (ASCT).
Alessandria, AlessandriaAges 18–60 - NCT05337241Recruiting
Saline enhanced needle ablation for stubborn heart rhythm
This trial studies a special “needle” ablation method (with saline) to treat a dangerous, repeat heart rhythm problem called monomorphic ventricular tachycardia (VT). It’s for adults whose VT keeps coming back despite prior treatments and who may not benefit from another standard ablation.
Birmingham, AlabamaAges 18 years+ - NCT05370430RecruitingPhase 1
CAR T therapy targeting BAFF-R for certain NHL
This Phase 1 study tests a new type of immune-cell therapy (CAR T cells) that targets BAFF-R to treat certain relapsed or refractory B-cell non-Hodgkin lymphoma (NHL). It aims to see if the treatment is safe and can shrink lymphoma in people who have tried prior therapies.
Duarte, CaliforniaAges 18 years+ - NCT05493722RecruitingEarly Phase 1
Adjusting deep brain stimulator settings for hard-to-control seizures
This early-phase study tests whether changing your deep brain stimulator settings can improve seizure control in people whose epilepsy is not helped by usual treatments. It is mainly for patients who already have the stimulator placed.
Minneapolis, MinnesotaAges 18 years+ - NCT05519085RecruitingPhase 3
Test mezigdomide vs pomalidomide with standard drugs for myeloma
This Phase 3 study compares two combination treatments for multiple myeloma that has come back or not gone away (relapsed or refractory). It aims to see whether mezigdomide, along with bortezomib and dexamethasone, works better than pomalidomide with those same medicines.
Los Alamitos, CaliforniaAges 18 years+ - NCT05546723RecruitingPhase 1
Study drug for multiple myeloma after several prior treatments
This Phase 1 trial tests LMY-920 in people with multiple myeloma that has returned or stopped responding after multiple standard therapies. It’s meant to see if the treatment can work and to better understand its safety and side effects in this situation.
Cleveland, OhioAges 18 years+ - NCT05556642Recruiting
Liver tumor registry for children with relapsed cancer
This study collects information and may collect fresh tumor tissue to better understand and model relapsed or hard-to-treat liver tumors. Joining could help researchers develop future treatments and more personalized research for affected patients.
Cincinnati, OhioAges Any age - NCT05565807RecruitingPhase 1/Phase 2
Study drug for difficult myeloma after prior treatments
This trial tests an anti-CD38 antibody drug that is “linked” to a cancer-killing payload (an antibody-drug conjugate) in people with multiple myeloma that has returned or did not respond to standard treatments. It is mainly looking at safety first, and also whether it can reduce myeloma in heavily pre-treated patients.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05652335RecruitingPhase 1
JNJ-79635322 for hard-to-treat myeloma or amyloidosis
This Phase 1 study tests how safe and how well JNJ-79635322 works in people with multiple myeloma that has come back or is resistant to treatment, or AL amyloidosis that has already been treated. It may help by targeting cancer cells and abnormal proteins driving these diseases.
Duarte, CaliforniaAges 18 years+ - NCT05672147RecruitingPhase 1
CD33 CAR T cells for hard-to-treat AML
This Phase 1 study tests a personalized immune-cell treatment (CD33 CAR T cells) for adults with AML that has returned or did not respond to treatment. It aims to see how safe the therapy is and how well it works for AML cells that carry the CD33 marker.
Duarte, CaliforniaAges 18 years+ - NCT05726110RecruitingPhase 3
Selinexor for relapsed or refractory AML in combination treatments
This Phase 3 trial studies selinexor (a medicine that changes signals inside cancer cells) used together with other leukemia treatment regimens for adults whose acute myeloid leukemia (AML) has come back or did not respond to standard therapy. It may help people reach remission or control the disease better than the current approach.
Taiyuan, ShanxiAges 18–60 - NCT05741164RecruitingPhase 2
Propranolol plus pembrolizumab for hard-to-treat breast cancer
This Phase 2 trial studies whether adding propranolol to pembrolizumab can “re-sensitize” tumors and slow cancer in triple-negative breast cancer that no longer responds to checkpoint immunotherapy. It may help some people whose cancer has grown despite prior pembrolizumab and chemotherapy.
Atlanta, GeorgiaAges 18 years+ - NCT05752552RecruitingPhase 1
Safety study of a MET-targeting pill for advanced lung cancer
This Phase 1 trial tests DO-2 to see how safe it is and how the body absorbs it (pharmacokinetics) in people with advanced or metastatic lung cancer. It is for tumors that have a specific MET exon 14 “skipping” mutation and for whom standard treatments are no longer an option.
BrusselsAges 18 years+ - NCT05757310RecruitingPhase 1
Stem cell transplant with lower-intensity chemo for severe aplastic anemia
This Phase 1 trial tests a “lower-intensity” chemotherapy plan followed by a stem cell transplant from a related half-match donor for severe aplastic anemia that has returned or did not respond to prior medicines. It aims to see if this approach is safe and works well enough to help your blood counts recover.
Duarte, CaliforniaAges Up to 75 years - NCT05768529RecruitingPhase 1/Phase 2
Study drug U16 for relapsed or refractory CD20 lymphoma
This trial tests U16 in people with CD20-positive non-Hodgkin lymphoma that has come back or not responded after prior treatments. It may help your immune system attack the lymphoma, and researchers will check safety and early signs of benefit.
Changsha, HunanAges 18–70 - NCT05800405RecruitingEarly Phase 1
Radiation before CAR T therapy for large B-cell lymphoma
This early-phase study tests whether giving targeted radiation first can improve outcomes when you later receive CAR T-cell therapy for large B-cell lymphoma that has come back or is not responding to treatment. It may help shrink or control lymphoma spots before CAR T is infused.
Duarte, CaliforniaAges 18 years+ - NCT05806580RecruitingPhase 4
Second relma-cel infusion for returning B-cell lymphoma
This trial looks at giving a second dose of relma-cel (a type of CAR-T therapy) for B-cell lymphoma that came back or did not fully respond after the first treatment. It may help shrink tumors again, but it requires that side effects from the first treatment and pre-chemo are mostly gone and that you meet infection and blood-test safety checks.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05847569RecruitingPhase 2
Testing alternating doses of belantamab for hard-to-treat myeloma
This Phase 2 trial tests whether alternating doses and schedules of belantamab mafodotin can help people with multiple myeloma that has returned or kept progressing after several prior treatments. You may be eligible if your disease has specific measurable signs and your blood counts and organs are healthy enough for study treatment.
Jacksonville, FloridaAges 18 years+ - NCT05852717RecruitingPhase 2
Epcoritamab plus GDP chemotherapy for relapsed large B-cell lymphoma
This Phase 2 study tests epcoritamab combined with GDP chemotherapy to treat adults whose large B-cell lymphoma has come back or did not respond to prior treatment. It aims to improve how safely and effectively the disease can be controlled after standard chemotherapy.
Indianapolis, IndianaAges 18 years+ - NCT05870995RecruitingPhase 2
Chemo plus targeted conditioning for hard-to-treat AML
This trial studies a specific chemotherapy plan (called sequential CLAG-Ven) with a gentler “conditioning” treatment before a transplant or donor-based therapy. It may help people with refractory or quickly relapsing acute myeloid leukemia (AML) who have a suitable family or matched donor and can meet certain organ function and infection rules.
Shanghai, Shanghai MunicipalityAges 16–65 - NCT05910801RecruitingPhase 2
Tafasitamab plus lenalidomide and venetoclax for relapsed lymphoma
This Phase 2 trial studies tafasitamab together with lenalidomide and venetoclax in people with mantle cell lymphoma (MCL) that has come back or did not respond to prior treatment. It may help shrink the lymphoma and improve disease control when standard options have not worked.
