Jupiter Endovascular Receives FDA Approval for U.S. Pivotal Study of Vertex Pulmonary Embolectomy System Using Endoportal Control

Jupiter Endovascular, Inc., a medical technology startup developing a new class of endovascular procedures using Endoportal Control™ to bring the precision and control of direct surgical access to catheter-based interventions, announced today that the U.S. Food and Drug Administration (FDA) has approved its Investigational Device Exemption application for the SPIRARE II U.S. pivotal study (NCT06576427).

The pivotal trial will study the Vertex Pulmonary Embolectomy System, which incorporates Jupiter’s novel Endoportal Control™ platform technology into an innovative endovascular procedure intended to treat Acute Pulmonary Embolism (PE) with an unprecedented level of control and precision. Endoportal Control™ is designed to bring these benefits to a variety of catheter interventions, with the goal of enabling interventionalists to deliver treatment to anatomical sites that they cannot safely or easily reach with a conventional endovascular approach. The endoportal device is delivered in a flexible, relaxed state over a guidewire to the target location in the vasculature, pressurized with saline to fix it in a stable position for therapeutic delivery, then relaxed again to navigate to another target location or for removal.

SPIRARE II is a prospective, single-arm, multicenter pivotal trial that will enroll up to 145 patients with acute, intermediate-risk PE treated with the Vertex Pulmonary Embolectomy System at up to 25 U.S. sites. Trial endpoints will characterize the procedural and clinical benefits of PE treatment with Endoportal Control™ using the Vertex system, across measures of safety, right heart function, and clinical improvement from the time of the procedure to 30 days post-procedure. SPIRARE II is part of Jupiter Endovascular’s SPIRARE clinical program, which also includes the SPIRARE I clinical study evaluating the Vertex system at up to two sites in Europe.

“One of the remaining challenges in treating PE is the ability to safely navigate through the right heart and into multiple areas of the pulmonary vasculature. The act of placing stiff interventional devices across the right heart may add stress to a strained right ventricle, and today’s catheters can become difficult to purposefully control beyond the main pulmonary arteries,” said Catalin Toma, MD, Director of Interventional Cardiology for the Heart and Vascular Institute at the University of Pittsburgh Medical Center (UPMC) and national co-principal investigator for the SPIRARE II trial. “These risks pose a barrier to the widespread adoption of large-bore catheter therapies for PE, creating the need for a procedural system that can safely access the pulmonary arteries with increased control.”

“In open surgery, we have the benefit of being able to directly visualize the anatomy and the instruments with which we are working. This provides surgeons with an excellent level of control and precision,” said Joshua Goldberg, MD, Surgical Director of the Structural Heart Surgery Program at Weill Cornell Medical Center in New York and national co-principal investigator of SPIRARE II. “A percutaneous embolectomy system that can provide interventionalists with the control and stability we enjoy in surgery holds the potential to dramatically improve procedural safety, efficacy, and efficiency.”

“We are excited about FDA approval of the first pivotal study of a system leveraging our Endoportal Control™ platform technology. In the more than 25 animal studies conducted to-date with the technology, it has demonstrated safe and easy navigation through the heart and vasculature, and effective delivery of test interventions,” said Carl J. St. Bernard, Jupiter Endovascular CEO. “Endoportal Control™ has the potential to meaningfully improve many endovascular procedures while enabling entirely new therapies. Our Vertex system for pulmonary embolectomy is the first of what we intend to be a portfolio of our own interventional procedure systems incorporating Endoportal Control™ to treat a variety of cardiovascular conditions that affect millions of patients worldwide.”

Pulmonary embolism occurs when a blood clot travels through the bloodstream – often as a result of deep vein thrombosis in the legs – ultimately blocking blood flow to the lungs. It is the third leading cause of cardiovascular death in the Western world, affecting as many as 900,000 U.S. patients each year and killing 10-30% of them within one month of diagnosis.

About Jupiter Endovascular

Jupiter Endovascular is a medical technology startup developing the “endoportal procedure,” a new class of endovascular procedures using Endoportal Control™ to bring the precision and control of direct surgical access to catheter-based interventions. The procedure uses an endoportal device that navigates flexibly through the vasculature via percutaneous access. Once in position, the endoportal device can be fixed into a stable state to deliver an interventional treatment with surgical-like precision and control from an endovascular access point.
