Endpoints

Primary: Part A: Determine the maximum tolerated dose (MTD) and/or the recommended dose(s) for expansion (RDE[s]), Part B: Evaluate the Objective response rate (ORR) of CLSP-1025 as a monotherapy in HLA-selected patients with advanced solid tumors that express the p53 R175H mutation

Secondary: Disease Control Rate, Duration of response (DOR), Half-life (t1/2) of CLSP-1025, Maximum plasma concentration (Cmax) of CLSP-1025, Number of patients with treatment-emergent adverse events, as assessed by CTCAE, v5.0, Number of patients with treatment-related adverse events, as assessed by CTCAE, v5.0, Overall Survival (OS), Part A: Objective Response Rate (ORR)
