About this trial
CAPTIVATE is a multi-center translational and observational trial, that aims to investigate the impact of the gut microbiome on treatment outcomes in women with untreated, stage I-III Triple Negative undergoing neoadjuvant treatment with and without immune checkpoint inhibitors. As part of the trial, stool samples, core tumors biopsies and research bloods samples for the analysis will be collected at various points of the study.
