Irinotecan Liposomes Combined with Cetuximab + Vermofenib in First-line Failure of Advanced Colorectal Cancer

Официальное название

Phase II Exploratory Study of Irinotecan Liposomes Combined with Cetuximab + Vermofenib in First-line Failure of Advanced RAS Wild /BRAF Mutated Colorectal Cancer

Обзор

Efficacy and safety of irinotecan liposomes combined with cetuximab + vermofenib in first-line failure of advanced RAS wild /BRAF mutated colorectal cancer, Exploratory analysis of biomarkers (including but not limited to ctDNA, immune microenvironment indicators, tumor mutation load, lymphocyte subsets, cytokines, gut microbes, and others) in relation to efficacy.

Подробное описание

This study aims to explore the following key questions: 1) whether replacing ordinary irinotecan in VIC protocol with irinotecan liposomes can improve the safety and efficacy of BRAF V600E mutation in second-line treatment of metastatic colorectal cancer; 2) To provide a reference for identifying the dominant population for the benefit of irinotecan liposomes through the exploration of a range of biomarkers (including but not limited to ctDNA, immune microenvironmental indicators, tumor mutation load, lymphocyte subsets, cytokines, gut microbes, and others). Thus, it provides more treatment options for BRAF V600E mutations in patients with metastatic colorectal cancer
