Study of GS-4321 for chronic hepatitis delta
This trial tests a new drug, GS-4321, for people with chronic hepatitis delta, a serious liver infection. It aims to see if the drug is safe and effective, and compares results in healthy volunteers and those with the virus.
Anaheim, CaliforniaAges 18–69 - NCT06126601Recruiting
Study on blood enzyme levels after pancreas surgery
This study checks if high levels of a certain enzyme (called amylase) in the blood after pancreas surgery can help predict recovery and complications. The goal is to improve patient safety after the operation.
DresdenAges 18–85 - NCT05652361Recruiting
AI guidance system for robotic rectal cancer surgery
This trial tests a machine-learning (AI) system that may help guide surgeons during robotic rectal cancer operations. It’s meant to support safer, more accurate surgery while comparing outcomes to standard surgical guidance.
Dresden, SaxonyAges 18 years+ - NCT06979336RecruitingPhase 2
New drug for moderate to severe UC
This study tests an experimental drug called RO7837195 for people with moderate to severe ulcerative colitis (UC) who haven't gotten enough help from other treatments. It aims to see if this new drug can reduce inflammation and improve symptoms.
Lancaster, CaliforniaAges 18 years+ - NCT07544589RecruitingPhase 1
Testing DISP-10 for Advanced Gastrointestinal Cancers
This early-stage trial tests a new experimental therapy called DISP-10 in patients with advanced cancers of the stomach, esophagus, or colon that have spread. The goal is to see if this treatment can help shrink tumors and how safe it is.
Duarte, CaliforniaAges 18 years+ - NCT07658196RecruitingPhase 1
TLR9 immunotherapy for stomach or appendix cancer spreading in the abdomen
This trial tests an experimental immunotherapy that targets a protein called TLR9 to help your immune system fight cancer cells that have spread into the lining of your abdomen (peritoneal carcinomatosis). It's for people with colorectal or appendix cancer that has spread this way and may also have some limited spread to the liver or lungs.
