a study of rc108-adc in subjects with advanced digestive system malignant tumor

Conditions: Digestive Cancer

Summary: a multi-center, open-label, study designed to evaluate the preliminary efficacy, safety and pharmacokinetics of rc108 in patients with c-me-positive advanced digestive system malignancies.

the primary purpose of this trial is to evaluate the preliminary efficacy, safety and efficacy of rc108 in patients with c-me positive advanced gastrointestinal malignancies such as gastric, colorectal, esophageal, hepatic, pancreatic and bile duct cancers.
