Intraoperative Use of the OTIS™ (OCT Imaging System) to Guide Additional Margin Cavity Shaves in Breast Conserving Surgery (BCS)

Note: A retrospective review of the stated purpose and objectives of the PER-19-02 protocol has determined that this study better fits the definition of a medical device feasibility study, with regard to FDA guidance "Investigational Device Exemptions (IDEs) for Early Feasibility Medical Device Clinical Studies, Including Certain First in Human (FIH) Studies," issued October 2013. The primary objectives of the PER-19-02 study (NCT04314700) emphasize user factors, rather than health outcomes, as the focus is on collecting information related to usability and timing, with no change to the standard of care (pathology analysis and additional surgery when needed). PER-19-02 was not used as a pivotal study to support the substantial equivalence or safety and effectiveness evidence submitted as part of an FDA pre-market submission. The IDE-approved pivotal study for evaluating the effect of Perimeter's OCT technology on health-related outcomes in breast surgery is the randomized control trial registered on ClinicalTrials.gov under protocol PER-19-04 (NCT05113927). Perimeter has determined this trial does not meet the definition of an Applicable Clinical Trial per the "Checklist for Evaluating Whether a Clinical Trial or Study is an Applicable Clinical Trial (ACT) Under 42 CFR 11.22(b) for Clinical Trials Initiated on or After January 18, 2017."
