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 - NCT07189715Recruiting
Testing a new memory technique for anxiety
This trial tests a technique called imagery rescripting, which helps change how you remember upsetting memories from childhood. A computer program may help make this more effective. This could help people with high anxiety who remember their parents being critical.
Poznan, WielkopolskaAges 18–35 - NCT07188220Recruiting
Understanding patient views on fatty liver disease study
This study asks people with metabolic fatty liver disease and liver scarring about their experiences. It aims to learn what matters to you so doctors can improve care.
BarcelonaAges 18–75 - NCT07187154Recruiting
Symptom management after esophagus cancer surgery
This trial tests a symptom management program using a WeChat mini program for people recovering from esophagus cancer surgery. It aims to help you track and manage your symptoms based on your own reports after the operation.

TR-002 for advanced solid tumors and pancreatic cancer
This trial tests a new drug called TR-002 in people with advanced solid tumors (cancer that has spread) who have run out of standard treatment options. It includes a specific group for people with pancreatic cancer that is no longer responding to chemotherapy.
Sacramento, CaliforniaAges 18 years+ - NCT07185932RecruitingEarly Phase 1
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.

MAGNIFY Study: New MRI for cystic fibrosis lung health
This study tests a new type of MRI scan that uses either special gas (xenon) or regular MRI to take detailed pictures of the lungs in people with cystic fibrosis. The goal is to see how well these scans can track lung health over time, without using X-ray radiation.
