Summary

A Phase 2 Study of ARX788 in HER2-positive, Metastatic Breast Cancer Patients whose Disease is resistant or refractory to Tyrosine kinase inhibitors (TKI).

Description

This is an open-label, single arm, phase 2 study of ARX788 in HER2-positive, metastatic breast cancer patients whose disease is resistant or refractory to TKI. The ARX788 will be administered every 3 weeks (Q3W) intravenous (IV) infusion. In this study, Simon's two-stage design is used. Subjects received treatment until disease progression, intolerable toxicity, withdrawal from the study, or discontinuation judged by the investigator. Drug efficacy and safety data will be collected.
