This early-phase trial is testing a combination of two drugs—trastuzumab rezetecan and retlirafusp alfa—in 12 people with HER2-positive stomach or gastroesophageal junction cancer. The treatment is given before surgery to see if it can safely shrink tumors. The main focus is on s…

This early-phase trial tests whether adding two targeted drugs (zanidatamab and tislelizumab) to standard chemotherapy can completely eliminate HER2-positive gastroesophageal cancer before surgery. About 29 adults with operable, locally advanced disease will receive the combinati…

This phase II trial tests whether adding low-dose radiotherapy and the immunotherapy drug tislelizumab to standard chemotherapy can improve outcomes for people with locally advanced stomach or gastroesophageal junction cancer. About 114 participants will be randomly assigned to r…

This Phase II trial tests a new combination of two immunotherapy drugs (iparomlimab and tuvonralimab, together called QL1706) plus chemotherapy for people with advanced HER2-negative stomach or gastroesophageal junction cancer. The study will enroll 64 participants who have not h…

This phase 2 trial tests two different drug combinations given before surgery for people with a specific type of stomach cancer (dMMR/MSI-H). Participants will receive the immunotherapy drug adebrelimab plus either chemotherapy or another immunotherapy drug (SHR-8068). The goal i…
