About this study

Researchers are testing a new treatment, CLSP-1025, for adults with solid tumors that have the p53 R175H mutation. The trial will determine the best dose of CLSP-1025 to use in people with this type of cancer.

Based on ClinicalTrials.gov records.

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)
