ICK-Breast: Immunotherapy-related CRP Kinetics in Early and Metastatic Triple-negative Breast Cancer
ICK-breast is a prospective, multicentric, non-interventional investigator-initiated trial (IIT) that aims to investigate the prognostic value of CRP kinetics in early and advanced or metastatic triple negative breast cancer (TNBC) under immune checkpoint inhibitor (ICI) therapy on pathological complete response (pCR) and event-free survival in early TNBC patients, and objective response rate (ORR), progression-free survival (PFS) and overall survival (OS) in advanced or metastatic TNBC.
• women ≥ 18 years of age
• histologically proven early or advanced or metastatic invasive breast cancer irrespective of therapy line
• ER-negative and progesterone receptor (PR)-negative and human epidermal growth factor receptor 2 (HER2)-negative (IHC 0-2+, Fluorescence In Situ Hybridization (FISH) neg.)
• patients with advanced or metastatic disease must be programmed cell death ligand 1 (PD-L1)-positive (IC ≥ 1 or combined positive score (CPS) ≥ 10) in the experimental group
• planned ICI therapy in combination with chemotherapy in the experimental group
• written informed consent into ICK-breast
