Triple Negative Breast Cancer (TNBC), Early Setting

LESLIE is a multicentric randomized controlled trial in patients with triple negative breast cancer receiving neoadjuvant chemo/immunotherapy (NAT). This trial investigates the hypothesis that adding a cyclic fasting-mimicking diet combined with exercise during the NAT improves the NAT's therapeutic efficacy, treatment tolerability and compliance, as well as improve quality of life.

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.

The phase III, multicenter, pragmatic PLANET trial aims to evaluate the benefit and safety of pembrolizumab as an addition to standard of care adjuvant treatment (capecitabine or olaparib) in triple negative breast cancer (TNBC) patients with residual disease (non-pCR) after neoadjuvant chemotherapy and pembrolizumab. All study procedures resemble routine clinical practice as much as possible (i.e., pragmatic clinical trial). In addition to the randomized trial, a registry will be set up, in which patients who reach pCR (and therefore, do not receive adjuvant treatment) will be registered and followed.
