Prospective Evaluation of AI R&D Tool for Patient Stratification - MoA Evaluation in Triple Negative Breast Cancer (PEAR-MET)

Pear Bio has developed an organ-on-a-chip device together with a computer vision pipeline through which the response of an individual patient's tumor to different systemic therapy regimens can be tested simultaneously ex vivo. This study will recruit patients with advanced or metastatic triple negative breast cancer who are due to start a clinically-indicated new line of therapy. The oncologist will be blinded to the response on the Pear Bio tool (the assay will be run in parallel with the patient's treatment). The primary objective of this study is to establish the sensitivity and specificity of Pear Bio's test against patient outcomes (response, progression-free survival, overall survival)
