Study BT8009-100 in Subjects With Nectin-4 Expressing Advanced Malignancies

Summary

This study is a Phase I/II, multicenter, first-in-human, open-label dose-escalation study of BT8009 given as a single agent and in combination with pembrolizumab in participants with advanced solid tumors associated with Nectin-4 expression or in participants with advanced solid tumor malignancies having renal insufficiency. The primary endpoints are: Dose limiting toxicities (Parts A-1 and A-2), Overall response rate per RECIST v1.1 (Parts B1-B7), Safety and tolerability (Parts B-8, B-9 and C), and characterization of the pharmacokinetics (Part D).
