Sequential anti-angiogenic therapy after immunotherapy for advanced bile duct cancer
This trial tests whether giving a drug that blocks blood vessel growth (anti-angiogenic therapy) after immunotherapy can help people with advanced bile duct, gallbladder, or cholangiocarcinoma that cannot be removed by surgery. The goal is to see if this sequence improves outcomes for patients who have not had prior treatment for advanced disease.

Chemotherapy in the belly for pancreatic cancer that has spread
This trial tests a combination of chemotherapy drugs (NALIRIFOX given through a vein plus paclitaxel given directly into the abdomen) for people with pancreatic cancer that has spread to the lining of the belly but not to other organs. The goal is to see if this approach is safe and effective.
Aurora, ColoradoAges 18 years+ - NCT07030348Recruiting
Early detection of pancreatic cancer using fluid from the upper gut
This study collects fluid from the first part of the small intestine (duodenum) during an endoscopy to see if it can help detect pancreatic cancer early. It is for people who already need an endoscopy for medical reasons.
Aurora, ColoradoAges 19 years+ - NCT07030829Recruiting
Laser vs shock wave for tough bile duct stones
This trial compares two ways to break up large or stuck bile duct stones that couldn't be removed with standard methods: laser or a shock wave device. If you have a difficult common bile duct stone, this study may help find the best treatment option.
