Brief summary

The objective of this study is to assess safety and efficacy of CAB-ROR2-ADC in solid tumors

Detailed description

This is a multi-center, open-label, Phase 1/2 study designed to evaluate the safety, tolerability, PK, immunogenicity, and antitumor activity of BA3021, a conditionally active biologic (CAB) ROR2-targeted antibody drug conjugate (CAB-ROR2-ADC) BA3021 in patients with advanced solid tumors. This study will consist of a dose escalation phase and a dose expansion phase with BA3021 in Phase 1. Phase 2 will study BA3021 alone or in combination with a PD-1 inhibitor.
