AbGn-7 was identified based on its direct killing (apoptosis-inducing) activities towards cancer cells expressing its epitope. In vitro data also demonstrated its ability to elicit CDC and ADCC. The in vivo xenograft study of AbGn-7 demonstrated that AbGn-7 alone or in combination with chemotherapeutic agents successfully suppressed the growth of gastric, pancreatic, and colorectal tumours. The NHP study proved the safety profile of AbGn-7. The present Phase 1 clinical study is designed to evaluate the safety and tolerability of AbGn-7 alone in patients with solid tumors of epithelial origin (Phase 1a) and in combination with a current chemotherapeutic regimen FOLFOX7 in patients with recurrent, locally advanced or metastatic gastric carcinoma (Phase 1b).
