Overview
This is a Phase Ia/Ib open-label, dose-escalation study to evaluate the safety and pharmacokinetics of ROSE12 as a single agent and in combination with other anti-tumor agents in patients with locally advanced or metastatic solid tumors. The study will consist of three parts: a dose-escalation part, a biopsy part (the part to evaluate biomarkers), and an expansion part.
