Официальное название

A Multicenter, Phase III, Randomized Controlled Trial Comparing Camrelizumab Plus Apatinib and Eribulin Versus Physician's Choice Chemotherapy in the Treatment of Advanced Triple-Negative Breast Cancer

Обзор

This study evaluates the efficacy and safety of camrelizumab, apatinib, and eribulin versus physician's choice chemotherapy in advanced TNBC.Primary Objectives: Assess improvements in progression-free survival (PFS) and overall survival (OS).Secondary Objectives: Compare objective response rate (ORR), disease control rate (DCR), clinical benefit rate (CBR), duration of response (DoR), time to response (TTR), two-year OS rate, biomarker analysis, and quality of life (QoL).Safety: Assess and compare adverse event incidence and severity.

Подробное описание

This study aims to evaluate the efficacy and safety of the triplet regimen compared to physician's choice chemotherapy as a later-line treatment for advanced triple-negative breast cancer (TNBC). 1. Primary Objectives and Endpoints: To determine whether the combination of camrelizumab, apatinib, and eribulin improves progression-free survival (PFS) and overall survival (OS) compared to investigator's choice chemotherapy in advanced TNBC. 2. Secondary Objectives and Endpoints: To compare the following clinical parameters between the camrelizumab, apatinib, and eribulin combination and investigator's choice chemotherapy for advanced TNBC: -Objective response rate (ORR) Disease control rate (DCR) Clinical benefit rate (CBR) Duration of response (DoR) Time to response (TTR) Two-year overall survival rate (2-year OS rate) Biomarker analysis Quality of life (QoL) analysis 3.Safety Evaluation: Comparison of the incidence and severity of adverse events between the two groups.

Platelet count ≥100×10⁹/L. Hemoglobin ≥9 g/dL. Serum albumin ≥3 g/dL. Thyroid-stimulating hormone (TSH) ≤ULN (if abnormal, T3 and T4 levels should be assessed; subjects with normal T3 and T4 levels are eligible).
