Intraoperative Use of an Optical Coherence Tomography (OCT) Imaging System to Guide Additional Margin Cavity Shaves in Breast Conserving Surgery (BCS)

NCT ID: NCT04314700

Last Updated: 2023-05-26

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: NA
• Total Enrollment: 58 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2020-02-11
• Study Completion Date: 2021-12-07

Brief Summary

Female patients undergoing a breast conserving procedure will be consented for the excised breast tissue to be imaged on an investigational OCT-based device. Additional tissue may be excised to obtain clear/negative margins based on routine standard of care tissue assessment techniques and intraoperative OCT image review.

Detailed Description

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."

Eligibility Criteria

Inclusion Criteria

• Female age 18 or older
• Patients undergoing elective breast conservation surgery for the treatment of Stage 0-III invasive ductal or lobular breast carcinoma and/or ductal carcinoma in situ
• May include subjects treated with neo-adjuvant endocrine therapy
• May include subjects treated with neo-adjuvant chemotherapy with confirmed complete clinical response
• Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

• Male
• Stage IV breast cancer
• Participation in another study that prolongs time to pathologic processing (greater than 1 hour)
• Neo-adjuvant treated patients with any chemotherapeutic who have not achieved a complete clinical response
• A surgeon makes an intraoperative decision to conduct a frozen section analysis (Any subject-specific data collected from an enrolled subject until the surgeon's intraoperative decision will not be used in the data analysis of this study. These subjects will be replaced in the study and the surgeon's intraoperative decision to conduct a frozen section analysis will be recorded).
