Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to assess the safety and efficacy of mecbotamab vedotin (BA3011) in solid tumors.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multi-center, open-label, Phase 1/2 study designed to evaluate the safety, tolerability, PK, immunogenicity, and antitumor activity of mecbotamab vedotin (BA3011), a conditionally active biologic (CAB) AXL-targeted antibody drug conjugate (CAB-AXL-ADC) in patients with advanced solid tumors.

Phase 1 of this study will consist of a dose escalation phase (enrollment complete as of Oct 2019) and a dose expansion phase (enrollment complete as of Jan 2024).

Phase 2 will consist of two parts. Part 1 is designed to evaluate mecbotamab vedotin alone and with nivolumab in patients with various types of advanced sarcomas (enrollment complete as of Jan 2024). Part 2 will evaluate the safety and efficacy of mecbotamab vedotin in patients with undifferentiated pleomorphic sarcoma (UPS) and myxofibrosarcoma (MFS).
