Johns Hopkins and Moffitt complete patient enrollment in post-approval study of novel breast cancer procedure

June 27, 2019

Dune Medical Devices has announced another milestone in their MarginProbe Post Approval Study (PAS) as Johns Hopkins Hospital and Moffitt Cancer Center complete their patient enrollments for the trial. This PAS, required by the FDA, seeks to substantiate the vast body of data produced since MarginProbe’s original approval, said the company, demonstrating its effectiveness at intraoperatively identifying positive margins and subsequent effects on reducing re-excision rates while maintaining cosmetic outcomes.

The adoption of MarginProbe by major cancer centers such as Johns Hopkins and Moffitt speaks volumes for the device’s credibility and efficacy, asserted the company, noting how nearly 200,000 women receive lumpectomy surgery annually, which precedes a period of uncertainty while awaiting final pathology results.

Dr. Mehran Habibi, Medical Director of the Johns Hopkins Breast Center, and Dr. Susan Hoover, Surgical Oncologist for Moffitt Cancer Center’s Department of Breast Oncology, are the participating Principal Investigators (PI) for their respective centers in the trial and are the number one and number two highest enrolling centers in the study.

Johns Hopkins and Moffitt now join Pinnacle Health Cancer Institute, Summit Medical Group, and Northshore University HealthSystem as sites which have completed enrollment in the study. The three sites will follow each patient for six months as required in the next phase of the study. To date, over 300 of the study’s 440 patients have been enrolled. Six additional cancer centers across the country will continue accruing patients until August 2019 when enrollment is anticipated to be complete.

“Participating in this study has allowed us to face the challenge of positive margin rates after lumpectomy head-on,” said Dr. Habibi in the statement.

Dr. Hoover also spoke about the opportunity. “With MarginProbe’s ability to identify positive margins in real-time and potentially lower re-excision rates, participating in this Post-Approval Study put us one step closer to accomplishing this goal,” she said.

The MarginProbe device utilizes radiofrequency spectroscopy to characterize and differentiate cancerous versus healthy tissue, giving surgeons the ability to identify microscopic residual cancer and DCIS in real-time, removing additional tissue if needed. MarginProbe provides greater confidence for both the surgeon and the patient that all of the cancer is successfully removed in the first surgery and reduces the likelihood of costly, burdensome additional surgeries.

A pathology report indicating a positive margin subjects patients to further surgery and a prolonged treatment timeline. Acceptance of MarginProbe as a standard of care, said the company, will provide significantly more women with the peace of mind that their cancer was fully removed during one procedure, and the ability to complete their treatment plan returning them back to their normal life.
