BeijingAges 18 years+ - NCT05353530RecruitingPhase 1
CAR T cell treatment for CD70-positive newly diagnosed glioblastoma
This trial tests a customized immune-cell treatment (CAR T cells) for adults with newly diagnosed glioblastoma (GBM) whose tumors have enough CD70 protein. If you qualify, the goal is to see whether this treatment can better control the cancer by targeting it in the brain.
Gainesville, FloridaAges 18–80 - NCT05354765Recruiting
Collect immune cells by lymphapheresis to study cancer response
This trial studies how changing your immune system (with earlier treatments) affects cancer by collecting immune cells from your blood using a process called lymphapheresis. It may help researchers find better ways to monitor immune-related responses and side effects.
ParisAges 18 years+ - NCT05354596Recruiting
SBRT radiation trial for central lung tumors
This trial studies a focused, high-dose radiation treatment called SBRT for lung tumors that are hard to operate on, including very central tumors near major airways or organs. It may help people control tumor growth while limiting radiation exposure to nearby critical structures.
AalborgAges 18 years+ - NCT05355051RecruitingPhase 2
Azacitidine plus pembrolizumab for Hodgkin lymphoma after relapse
This Phase 2 study tests azacitidine together with pembrolizumab in people whose Hodgkin lymphoma has come back or did not respond (relapsed/refractory). It aims to see whether this combination can control cancer and improve outcomes, especially when standard high-dose chemotherapy is not an option.
Houston, TexasAges 1 year+ - NCT05355363Recruiting
Check what happens after missed colon follow-up for colon polyps
This study looks at the risk of new or advanced colon findings in people who had certain colon polyp results, but then did not get the recommended follow-up colonoscopy on time. It may help doctors fine-tune how urgently different patients need repeat colon checks.
Montreal, QuebecAges 45–80 - NCT05356039Recruiting
Study of surgery options and quality of life in pancreatic cancer
This study looks at people with borderline-resectable or locally advanced pancreatic cancer to see how treatment choices affect survival, quality of life, and whether tumors can be removed by surgery. It may help doctors better predict who can benefit from surgical approaches and what outcomes matter most to patients.
UmeåAges 18 years+ - NCT05356117Recruiting
Exercise plus protein shakes for people with pancreatic cancer
This trial studies whether a supervised resistance exercise program combined with protein supplementation can help people with non-metastatic pancreatic cancer during chemotherapy. It may improve strength and how well you tolerate treatment, with safety monitoring throughout.
Boston, MassachusettsAges 18 years+ - NCT05356182Recruiting
Low-protein meals during immunotherapy for cancer patients
This trial tests whether eating low-protein meals helps people with metastatic cancer feel better or tolerate immunotherapy (immune checkpoint inhibitors). It’s mainly a pilot/feasibility study, meaning the goal is to see if the diet is safe and doable during treatment.
Buffalo, New YorkAges 18 years+ - NCT05357651RecruitingPhase 1
LB1410 study for advanced lung, colon, and other cancers
This Phase 1 trial tests LB1410, a new cancer treatment, to see if it is safe and may work for people with advanced cancers. It focuses on specific cancer types and requires certain prior treatments and lab test results.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05357846RecruitingPhase 3
Check whether PD-1 treatment helps esophagus cancer before surgery
This Phase 3 trial tests whether adding a PD-1 medicine (sintilimab) to standard chemo-radiation before surgery improves outcomes for locally advanced esophageal squamous cell cancer. It may help by strengthening the immune response while shrinking the tumor before an operation.
Guangzhou, GuangdongAges 18–70 - NCT05357794RecruitingPhase 2
Skin-directed radiation plus brentuximab for lymphoma skin disease
This Phase 2 trial studies whether giving very low-dose total-skin electron beam radiation at the same time as brentuximab vedotin can control mycosis fungoides (a lymphoma that affects the skin). It’s for people whose disease has returned or hasn’t responded to prior treatment, especially if the tumor marker CD30 is present.
Houston, TexasAges 18 years+ - NCT05358548RecruitingPhase 2
Alternating treatment for advanced lung and head-neck cancers
This Phase 2 study tests an approach that alternates treatments for advanced lung cancer or recurrent/metastatic head and neck squamous cell cancer. It may help by improving how well the cancer responds while managing side effects differently than standard back-to-back therapy.
Elizabeth, New JerseyAges 18 years+ - NCT05360290Recruiting
Study checks cancer cells in breast tissue after surgery
This trial looks for circulating tumor cells—cancer cells that may travel in the blood—after standard breast cancer treatment, including chemotherapy before surgery and surgery itself. It may help doctors understand who might be at higher risk and tailor follow-up care.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05359939Recruiting
MRI, CT, and PET scans compared for liver cancer
This study compares different scan types (MRI, CT, and two PET scans) in people with hepatocellular carcinoma (a primary liver cancer). It may help doctors figure out which scan gives the most useful information for diagnosis and treatment planning.
AarhusAges 18 years+ - NCT05360160RecruitingPhase 1/Phase 2
