ARTIDIS Nanomechanical Generated Measurements for Early Breast Lesions (ANGEL)

Objective: To test the performance of nanomechanical phenotype tests in predicting tumor type, tumor aggressiveness, and neoadjuvant treatment response, compared to the gold standard of histopathological assessment on testing suspicious lesions.

Study Design:

This is a multi-center, blinded, single-arm study designed to collect nanomechanical signature measurement data of biopsy material taken for clinical diagnostic purposes in subjects referred for breast biopsy. Routine demographic, diagnostic and treatment data will be collected, as well as response evaluations. Subjects with a benign biopsy will be followed for a maximum of 30 days, while subjects diagnosed with breast cancer will be kept in active, routine, clinical follow-up with information collected twice yearly for the first two years and annually for years three to ten. Intermediate treatment biopsies or tissue samples from surgery may be collected at participating sites where they are performed routinely as standard of care (SOC).

All patients referred to participating study sites for a core needle or vacuum-assisted breast biopsy may be eligible for this study. All patients will be asked for written, informed consent for de-identified tissue and data collection on disease, histology characteristics, outcome, on disease related patent information, and patient reported outcomes.

The 2nd tissue core or representative core biopsies taken from the study subjects will be further investigated with the ARTIDIS platform and subsequently re-entered into the routine pathological analysis within the same day. Only two biopsies will be assessed per ART-1 device per day. One in the morning and one in the afternoon to ensure that the diagnostic biopsy can be reentered into the routine pathological analysis. The ARTIDIS measured biopsies will be marked to identify the orientation of the biopsy in the ART-1 device before re-entering the routine pathological analysis.
