New drug velzatinib versus imatinib for untreated GIST
This trial compares a newer cancer drug (velzatinib) with a standard treatment (imatinib) for gastrointestinal stromal tumors (GIST) that cannot be surgically removed or have spread. You would receive one of these two drugs to see which works better and is safer.

VitaSmart HOPE System liver transplant registry
This study follows people who receive a liver transplant using a special machine called the VitaSmart HOPE System, which keeps the donated liver healthy before transplant. The study tracks how well these livers work after transplant.
Cleveland, OhioAges Any age - NCT07584135RecruitingPhase 3
JS107, Toripalimab, and Chemotherapy for Advanced Stomach Cancer
This study tests a combination of three treatments—JS107, toripalimab (an immunotherapy), and chemotherapy—for advanced stomach cancer that has a specific protein marker called CLDN18.2. The goal is to see if this combination can shrink tumors and help patients live longer.
