Saranas Successfully Completes Enrollment of Clinical Trial Assessing the Utility of Early Bleed Detection in Patients Undergoing Mechanical Circulatory Support

SAFE-MCS Examines the Impact of the Early Bird® Bleed Monitoring System on Reducing Bleeding Complications in Patients Undergoing High Risk PCI with Mechanical Circulatory Support

September 18, 2023, Houston, TX – Saranas, Inc. announced today that it has completed enrollment in SAFE-MCS, a multi-center, single arm, open-label clinical trial evaluating the safety of complex high-risk percutaneous coronary intervention (PCI) using mechanical circulatory support (MCS) and surveillance with the Early Bird® Bleed Monitoring System. The Early Bird Bleed Monitoring System is the first and only FDA-approved bleed detection system. It was launched in 2019 following a De Novo classification by the U.S. Food and Drug Administration. The device monitors and detects endovascular bleed complications through a novel application of bioimpedance sensors.

“With the global rise in utilization of MCS, the SAFE-MCS study aims to provide valuable understanding of the actual frequency of bleeding incidents during these procedures and strategies to enhance the safety of patients undergoing complex and high-risk treatments,” stated Dr. Philippe Genereux, interventional cardiologist and Director of the Structural Heart Disease Program at Morristown Medical Center and co-principal investigator of SAFE-MCS. 

SAFE-MCS enrolled 184 patients across multiple centers in the United States. The primary endpoint of the study is incidence of access-site related BARC (Bleeding Academic Research Consortium) type III or V bleeding. Patients undergoing complex high-risk PCI with mechanical circulatory support (MCS) via Impella and transfemoral arterial approach are enrolled as study participants. The Early Bird Bleed Monitoring System is used in the ipsilateral femoral vein to monitor bleeding events after MCS removal.

“Prompt detection of bleeding incidents is vital to prevent complications that can severely impact patients. The insights from SAFE-MCS will offer significant insight and guidance on how continuous monitoring can improve clinical outcomes by actively addressing bleeding events,” said Dr. Babar Basir, Director of Acute Mechanical Circulatory Support, at Henry Ford Health System and co-principal investigator of SAFE-MCS.

Approximately one in every five patients will experience a bleeding complication during large-bore endovascular procedures such as transcatheter aortic valve replacement (TAVR), endovascular aneurysm repair (EVAR), and percutaneous MCS. The average cost of a single bleeding complication incident across these large-bore procedures is approximately $18,000 with an estimated $729 million cost on the healthcare system1. The Saranas Early Bird Bleed Monitoring System is the first and only FDA-approved device for real-time monitoring of endovascular bleed complications.

“We are pleased to have completed enrollment of the SAFE-MCS trial,” said Saranas President and CEO Mike MacKinnon. “This marks a significant step in our journey to further establish clinical evidence for the effectiveness of the Early Bird device. Saranas is dedicated to setting a new standard for bleed detection during and after endovascular procedures, aiming to enhance patient outcomes and reduce the overall cost of healthcare.”

About the Early Bird Bleed Monitoring System

The Early Bird Bleed Monitoring System includes a bleed detection array with integrated electrodes in a fully functional vascular access sheath. It is designed to measure changes in bioimpedance to detect and monitor bleeding from vessel injury during endovascular procedures, such as a transcatheter aortic valve replacement (TAVR), mechanical circulatory support (MCS) device placement, or other complex endovascular interventions, where the femoral artery or vein is used to obtain vascular access. Visual and audible indicators on the Early Bird notify the clinician of the onset and progression of bleeding events. In the FIH clinical study, bleed detection with the Early Bird was compared with a CT scan, the gold standard, and level of agreement was nearly perfect with 100% sensitivity2.
