New FDA Clearance Validates In Vivo, Real-Time "Identification of Cellular and Vascular Organization and Architecture” Using Cellvizio®

Regulatory News:

Mauna Kea Technologies (Euronext: MKEA, OTCQX: MKEAY) (Paris:MKEA) (OTCQX:MKEAY) inventor of Cellvizio®, the multidisciplinary confocal laser endomicroscopy (CLE) platform, today announced that it has received its 14^th U.S. Food and Drug Administration (FDA) 510(k) clearance for the Cellvizio® 100 series and all of its Confocal Miniprobes™. FDA agreed that data from multiple peer-reviewed medical journals validate the technology’s ability to image the internal microstructure of tissues including, but not limited to, the identification of cells and vessels and their organization or architecture. The addition of the indications for: "identification of cells and vessels and their organization or architecture” to the previously cleared intended use (the fields of gastroenterology¹, urology² and pulmonology³ during endoscopic, laparoscopic manual and robot-assisted surgical, and image-guided percutaneous procedures), represents a pivotal milestone for in vivo real-time microscopic visualization technology.

"With this new clearance, Cellvizio is affirmed as the only platform for imaging and identification at the cellular and micro-vascular level during a wide variety of procedures in endoscopy and surgery,” said Sacha Loiseau, Ph.D., Founder and Chief Executive Officer of Mauna Kea Technologies. "This milestone enables us to formally shift from imaging to identification, providing us with strong leverage to broaden adoption by healthcare providers and payers.”

This new clearance builds on the recent executive summary published by the College of American Pathologists (CAP) which highlighted the potential value of in vivo microscopy (IVM). The summary noted that "the architectural and cellular patterns generated by IVM are interpretable by pathologists to make differential diagnoses and to identify areas for biopsy, improving diagnostic yield. Such directed biopsies decrease sampling errors resulting in fewer, less frequent biopsies, significantly decreased morbidity, and significant cost saving […]”⁴.
