Summary
Brief summary
This is a first-in-human, Phase 1, multicenter, open-label, dose-escalation study to establish the maximum-tolerated dose (MTD) or recommended dosage (RD) of ZW49, the investigational agent under study, and to assess the safety and tolerability of ZW49. Eligible patients include those with locally advanced (unresectable) or metastatic HER2-expressing cancers.
