Phase 12 Study of Sacituzumab Tirumotecan Alone or With Other Treatments for Advanced Gastrointestinal Cancers

What this Trial Is About

Researchers are investigating whether sacituzumab tirumotecan alone or combined with other treatments can treat certain advanced or unresectable gastrointestinal cancers, including colorectal cancer, pancreatic ductal adenocarcinoma, and biliary tract cancer. The study aims to understand the safety and tolerability of sacituzumab tirumotecan and how well the cancer responds to these treatments. Participants will receive sacituzumab tirumotecan in different dose levels either combined with chemotherapy every two weeks in a 4-week cycle, alone every two weeks in a 4-week cycle, or combined with cisplatin and pembrolizumab in a 3-week cycle. Treatment continues until the cancer worsens or participants cannot tolerate it. Cisplatin is given up to approximately six months, and pembrolizumab is administered for up to about two years in the combination group. During the study, participants will have regular assessments to monitor safety, side effects, and how the cancer responds via imaging and clinical evaluation. Researchers will track dose-limiting toxicities, adverse events, treatment discontinuations due to side effects, and objective response rates. Additional measures include duration of response, progression-free survival, and overall survival, with monitoring lasting up to approximately 63 months.
