A Study of IMU-131(HER-Vaxx) and Chemotherapy Compared to Chemotherapy Only in Patients With HER2 Positive Advanced Gastric Cancer

Summary

The Phase 1b study is an open-label, multicenter dose escalation study designed to assess the safety, tolerability, immunogenicity and recommended phase 2 dose (RP2D) of IMU-131. The RP2D will be evaluated in the dose expansion Phase 2 study. The Phase 2 study is a randomized, open label comparison of IMU-131 plus standard of care chemotherapy versus standard of care chemotherapy alone.
