Intact Vascular to Announce Six-Month Data from TOBA II BTK Clinical Trial

First Pivotal Study to Investigate Permanent Vascular Implant as a Treatment for Post-Angioplasty Dissections in Arteries Below the Knee (BTK)

WAYNE, Pa.--(BUSINESS WIRE)-- Intact Vascular, Inc., a developer of medical devices for minimally invasive peripheral vascular procedures, today announced that the six-month data from its Tack Optimized Balloon Angioplasty (TOBA) II BTK clinical trial will be presented during the Late-Breaking Clinical Trial session at the 16^th Annual VIVA Conference, November 4-7^th in Las Vegas, Nevada.

The TOBA II BTK study is notably the first U.S. IDE clinical study approved to investigate the safety and effectiveness of a permanent implant to repair dissections in BTK arteries. The single-arm prospective study enrolled 233 patients at 41 sites in the U.S., Europe and New Zealand. The majority of patients enrolled suffered from critical limb ischemia (CLI), underwent standard balloon angioplasty and consequently experienced at least one dissection that required repair with the Tack Endovascular System^®.

George Adams, M.D., M.H.S., Director of Cardiovascular and Peripheral Vascular Research, UNC Rex Hospital, Raleigh, North Carolina and Co-Principal Investigator of the TOBA II BTK trial, will present the six-month data on Tuesday, November 6^th at 9:15 am PST in the Global Theater/Lafite Ballroom of the Wynn Las Vegas hotel.

“We are very pleased to have the TOBA II BTK data presented as a Late-Breaking session at this year’s VIVA meeting, underscoring the clinical importance of this first-of-its-kind trial,” commented Peter Schneider, M.D., Co-Founder and Chief Medical Officer of Intact Vascular. “We look forward to sharing the positive findings of the Tack System and ultimately providing the first permanent implant solution for patients suffering from below-the-knee arterial disease.”

About Intact Vascular and the Tack Endovascular System

Intact Vascular is a privately held medical device company that develops minimally- invasive peripheral vascular products. The Tack Endovascular System is designed to repair dissections following peripheral balloon angioplasty. Pre-loaded with six self-expanding nitinol devices for above-the-knee (ATK) interventions, or four for below-the-knee (BTK) interventions, the Tack Endovascular System can be deployed to treat multiple dissections using a single catheter and leaving behind >70% less metal than stents.¹ Additionally, the Tack Endovascular System is designed to minimize vessel inflammation, promote healing, improve outcomes and preserve future treatment options for peripheral arterial disease patients.

Intact Vascular Clinical Program

Intact Vascular is sponsoring three clinical trials to evaluate its Tack Endovascular System: TOBA II, TOBA II BTK and TOBA III. TOBA II is investigating the combination of the Tack^® implant with plain angioplasty balloons and the BD Interventional Lutonix^® drug-coated balloon (DCB) in arteries above the knee and has completed its primary endpoint analysis. TOBA II BTK has also completed its primary endpoint analysis and is investigating the combination of the Tack implant with plain balloon angioplasty in the arteries below the knee. TOBA III has completed its primary endpoint analysis and is investigating the combination of the Tack implant with the Medtronic IN.PACT^™ Admiral^™ (DCB), with a long lesion subset.
