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

Official Title

A Phase 1/2 Safety and Efficacy Dose Escalation / Dose Expansion Study of a CAB-ROR2-ADC, Alone and in Combination With a PD-1 Inhibitor, in Patients With Advanced Solid Tumors (Ph1) and Melanoma and NSCLC Patients (Ph2)


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.


Non Small Cell Lung Cancer, Triple Negative Breast Cancer, Melanoma, Head and Neck Cancer, Head and Neck Neoplasms, Triple Negative Breast Neoplasms, Immune Checkpoint Inhibitors, CAB-ROR2-ADC, PD-1 inhibitor, Monotherapy - CAB-ROR2-ADC (BA3021) alone
