Penumbra Announces Key Events at International Stroke Conference 2018 Meeting

January 17, 2018

Results of Independent COMPASS Trial Comparing Aspiration to Stent Retrievers to be Presented

ALAMEDA, Calif.--(BUSINESS WIRE)-- Penumbra, Inc. (NYSE: PEN), a global healthcare company focused on innovative therapies, today announced key events at the upcoming International Stroke Conference 2018 meeting (ISC 2018) to be held January 24-26 at the Los Angeles Convention Center. These events include results from two new clinical studies evaluating the company’s aspiration thrombectomy system for ischemic stroke revascularization.

The results of the independent, prospective, randomized controlled COMPASS Trial (A Comparison of Direct Aspiration vs. Stent Retriever as a First Approach) will be presented by J. Mocco, M.D., M.S., Ichan School of Medicine at Mount Sinai, New York. The multi-center COMPASS Trial compared mechanical thrombectomy with the ADAPT (A Direct Aspiration First Pass Technique) approach to stent retrievers in patients presenting with acute ischemic stroke (AIS) within six hours of symptom onset. The COMPASS Trial planned to enroll approximately 270 patients at up to 20 centers. The presentation is scheduled for Thursday, January 25 from 11-11:12 a.m. PT.

In addition, results of the company-sponsored PROMISE Study (Reperfusion with ADAPT Technique using ACE™68 and ACE64 is Safe and Effective in Large Vessel Occlusions of the Anterior Circulation) will be presented by Peter Schramm, M.D., Universitätsklinikum Schleswig-Holstein, Lübeck, Germany. The PROMISE Study was a prospective, single-arm multi-center study that enrolled 204 patients across 20 European centers using ADAPT with the Penumbra System® as frontline treatment. The presentation is scheduled for Wednesday, January 24 from 6:30-7 p.m. PT.

Attendees will also have the opportunity to learn more about the company’s portfolio of products, including the Penumbra System, Penumbra SMART COIL® System and Artemis™ Neuro Evacuation Device, at Penumbra booth #521 in the Science and Technology Hall.

About COMPASS Trial

The COMPASS Trial: A Comparison of Direct Aspiration vs. Stent Retriever as a First Approach is an independent, prospective, randomized trial that compared mechanical thrombectomy with the ADAPT (A Direct Aspiration First Pass Technique) approach to stent retrievers in patients presenting with acute ischemic stroke (AIS) within six hours of symptom onset. The primary objective of the trial was to show that AIS patients, with appropriate image selection, treated with the ADAPT approach within 6 hours of symptom onset do not have inferior clinical outcomes to those treated with a first-line stent retriever with 90-day global disability assessed via the modified Rankin Scale score (mRS) analyzed using success criteria as mRS 0 to 2. The study planned to enroll 270 patients at up to 20 centers in the U.S., and was funded by the company through a research grant. (Clinicaltrials.gov Identifier: NCT02466893)

About Penumbra’s Neuro Products

Penumbra has a growing portfolio of products for use in a range of neuro procedures:

  • The Penumbra System® is a fully integrated system designed specifically for mechanical thrombectomy by aspiration that first received 510(k) clearance by the U.S. Food & Drug Administration in December 2007. The Penumbra System enables physicians to use aspiration, which acts like a minimally invasive “vacuum” inside the artery to remove stroke-causing blood clots from the brain safely and effectively. It is intended for use in the revascularization of patients with AIS secondary to intracranial large vessel occlusion. The latest generation of the Penumbra System features the ACE™ Reperfusion Catheters, Hi-Flow Aspiration Tubing, the 3D Revascularization Device™ and Pump MAX™ aspiration pump and accessories. Launched in 2016, the ACE68 Reperfusion Catheter offers outstanding trackability and enables even greater aspiration power for clot removal through its large .068” lumen. Launched in 2017, the 3D Revascularization Device is a next generation stroke device, designed and optimized for aspiration with ACE Reperfusion Catheters.
  • Penumbra’s neuro embolization systems are designed to meet the unique challenges of aneurysm coiling, vessel sacrifice and other neurovascular malformations. The Penumbra SMART COIL® is a 10-size, detachable, platinum embolization coil system specifically engineered to offer smooth, controlled coil delivery using the latest innovations in coil design and material science. The Penumbra Coil 400™ is a large-volume, detachable, platinum coil system engineered to offer four times the volume of a 10-size coil to efficiently embolize large aneurysms and other large, complex lesions.
  • Artemis™ Neuro Evacuation Device is specifically designed for the controlled evacuation of fluids and tissues from the ventricular system and cerebrum. Artemis is Penumbra’s second generation device, following the introduction of the Apollo System in 2014. Artemis is a minimally invasive surgical tool that utilizes Pump MAX for powerful and controlled hematoma evacuation.
