About this study

This phase 1/2 , open-labelled, multi-center study is designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics, and preliminary clinical activities of UI-102 in patients with advanced solid tumors. Phase 2 part is designed to assess the efficacy and safety as well as to optimize the dosing amount of UI-102
