Clinical Trial Summary

The primary objective of this phase I study is to evaluate the safety and potential efficacy and to determine the recommended phase 2 dose (RP2D) of IBI315, a HER2/PD-1 bi-specific antibody in patients with advanced solid tumors

Description:

This phase Ia/Ib, open-label, multicenter study has two stages. The Ia stage is a dose-escalation study that will focus on safety, tolerability, efficacy and RP2D . Patients with HER2-expressing advanced solid tumor who failed from previous standard of care will be enrolled in the phase Ia study. DLT observation period is 28 days.
