Overview
Brief Summary
This study is to evaluate the efficacy and safety of JAB-30355 in adult participants with advanced solid tumors harboring TP53 Y220C mutation.
Detailed Description
This study consists of two parts: Dose Escalation Phase (Phase 1) and Dose Expansion Phase (Phase 2a). The primary objective of dose escalation is to evaluate the safety and tolerability, and to determine the MTD of JAB-30355 monotherapy administered in participants with advanced solid tumors harboring TP53 Y220C mutation. Dose expansion will further explore JAB-30355's clinical benefit and tolerability in selected dose levels.

Arms & Interventions
Dose expansion phase
Dose Expansion Phase will explore JAB-30355's clinical benefit and optimal tolerability in selected dose level.
Intervention: JAB-30355 (Drug)
Dose escalation phase
Multiple dose levels of JAB-30355 will be explored to determine the maximum tolerated dose (MTD)
Intervention: JAB-30355 (Drug)
