PBC treatment response and long-term health outcomes
This research study tracks how well Primary Biliary Cholangitis (PBC) responds to standard medication (UDCA) and what happens to patients' health over time. It may help doctors understand which treatments work best for different people.

Targeted drug for advanced biliary tract cancer after standard treatment
This trial tests a new targeted drug (SHR-A1904) in people with advanced biliary tract cancer whose tumors have a specific protein (Claudin18.2) and who have already tried at least one standard treatment. The goal is to see if this drug can shrink the cancer or slow its growth.

Study of new drug for metastatic pancreatic cancer
This trial tests a new drug called nuzefatide pevedotin for people with metastatic pancreatic cancer that has progressed after one prior treatment. The drug targets a protein called EphA2 found on some tumor cells and may slow tumor growth.
Phoenix, ArizonaAges 18 years+ - NCT03740503Recruiting
Study genes in people who respond unusually to treatment
This study looks at stored tumor samples to understand why some people respond much better or much worse than expected. The goal is to learn what the tumor’s genes might be telling doctors about response to treatment.
Toronto, OntarioAges 18 years+ - NCT05412758Recruiting
Breath and blood tests to study stomach and food-pipe cancer
This study looks at how certain “volatile” substances in breath change in people with stomach or food-pipe (oesophageal) cancer, compared with people who have other non-cancer stomach/food-pipe conditions. It may help researchers find better, earlier ways to assess cancer—especially in people who have not started treatment yet.
LondonAges 18–90 - NCT06387342RecruitingPhase 2
Namodenoson for advanced pancreatic cancer
This trial tests an oral drug called Namodenoson for people with advanced pancreatic cancer that has not responded to previous treatments. The goal is to see if the drug can help slow the cancer's growth or improve symptoms.
Petah TikvaAges 18 years+ - NCT05752071Recruiting
Stomach stimulation to help bowel recovery after major surgery
This trial tests a stomach (gastrointestinal) stimulation approach to help your bowels start working again after extensive surgery, which may cause a temporary problem called postoperative ileus. If it helps, it could mean faster recovery and less time with bowel-related complications.
AarhusAges 18 years+ - NCT06802666RecruitingPhase 2
Short radiation plus combo drugs for rectal cancer
This trial tests a new combination for rectal cancer that hasn't spread far: a short course of radiation followed by two drugs (AK112 and CAPOX). The goal is to shrink the tumor before surgery and possibly avoid more aggressive treatments.
HubeiAges 18–75 - NCT06802731Recruiting
Testing a tool to measure liver inflammation in NAFLD
This trial studies a device called LivQ-box to see if it can accurately measure liver inflammation in people with nonalcoholic fatty liver disease (NAFLD). It compares the device's results to a liver biopsy.
