Rifaximin for fatty liver with metabolic issues
This trial tests if rifaximin, a gut-targeted antibiotic, can help people with fatty liver disease who also have metabolic problems like obesity or diabetes. You need a recent fatty liver diagnosis and a liver fat level of at least 8% on an MRI scan.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07183865RecruitingPhase 2
Radiation, chemo, and immunotherapy for recurrent rectal cancer
This trial tests a new combination of radiation, chemotherapy (NALIRIF), and an immunotherapy drug (PD-1 antibody) for rectal cancer that has come back in the pelvis. The goal is to see if this approach can help control the cancer better.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05960955RecruitingPhase 2
Testing immunotherapy plus chemo around the time of gastric surgery
This study tests whether adding cadonilimab (and possibly AK117) to chemotherapy can improve outcomes for people with resectable stomach or stomach–esophagus cancer. It aims to see if this combination works better than chemotherapy alone, while still being safe around surgery.
TianjinAges 18–75 - NCT07510308RecruitingPhase 1
Vaccine trial for advanced colorectal cancer
This trial tests a personalized vaccine made from your own tumor cells for advanced colorectal cancer that is mismatch repair proficient (pMMR). It aims to see if the vaccine can help when standard treatments have stopped working.
Chengdu, SichuanAges 18–75 - NCT07507643RecruitingPhase 3
Steroid treatment before liver surgery study
This study tests if a steroid called methylprednisolone can help people recovering from major liver surgery. It aims to see if it reduces inflammation and improves outcomes.
Chicago, IllinoisAges 18 years+ - NCT07107633RecruitingPhase 2
Imaging test for cancer spread in the abdomen
This trial tests a special imaging injection to see if it can better detect cancer that has spread to the lining of the abdomen in people with stomach or bowel cancer. If you are scheduled for surgery to remove or explore the cancer, this scan might help your doctor plan the best treatment.
ShanghaiAges 18 years+ - NCT06262451Enrolling by invitation
Fecal transplant national registry study
This study creates a registry for people who receive fecal microbiota transplants (FMT) to track long-term safety and outcomes. It may help researchers understand how this treatment works over time.
San Francisco, CaliforniaAges Any age - NCT06915818Recruiting
Magnet-assisted colon surgery study
This trial tests a new device that uses magnets to connect parts of the colon after surgery. It may help people who need certain types of colon removal and reconnection surgery.
Santiago, Huechuraba, Región MetropolitanaAges 22 years+ - NCT07574437Recruiting
At-Home Bowel Stimulation After Colon Surgery
This study tests whether a at-home bowel stimulation device can help patients who have had part of their colon removed and currently have a temporary ileostomy (an opening in the belly that drains stool). The goal is to see if this approach might improve bowel function before or after closing the ileostomy.
Weston, FloridaAges 18 years+ - NCT06747845RecruitingPhase 2
Maintenance therapy for stable metastatic pancreatic cancer
This trial tests a combination of two drugs, niraparib and ipilimumab, as a maintenance treatment for people with metastatic pancreatic cancer that has not grown after initial chemotherapy. The goal is to see if this can help keep the cancer stable longer.
Boston, MassachusettsAges 18 years+ - NCT06016855RecruitingPhase 4
Surgery before radiation therapy for neuroendocrine tumors
This trial tests if removing as much tumor as possible through surgery before a targeted radiation therapy (PRRT) can help people with well-differentiated neuroendocrine tumors that have spread to the liver. The goal is to see if this approach works better than radiation therapy alone.
Nashville, TennesseeAges 18 years+ - NCT05688215RecruitingPhase 1/Phase 2
Zimberelimab and quemliclustat with chemotherapy for pancreatic cancer
This trial studies how well zimberelimab and quemliclustat work together with standard chemotherapy for people with borderline resectable or locally advanced pancreatic cancer. It may help shrink the tumor and make treatment more effective before or around the time surgery is considered for some patients.
