Stellarex ILLUMENATE Pivotal Results are Top-tier in the Most Complex Patient Group Studied in DCB IDE Trials

COLORADO SPRINGS, COLO. (November 2, 2016) – The Spectranetics Corporation today announced that Dr. Sean Lyden presented the final 12-month results of the Stellarex Drug-coated Balloon (DCB) ILLUMENATE Pivotal Trial at the Transcatheter Cardiovascular Therapeutics (TCT) conference in Washington, D.C. The ILLUMENATE Pivotal Trial’s Co-Principal Investigators are Dr. Lyden, of the Cleveland Clinic, and Dr. Prakash Krishnan of Mount Sinai in New York.

Dr. Krishnan stated, “First generation drug-coated balloons forced us to make a choice between top-tier clinical outcomes and the potential safety advantages of a lower drug dose. Based on the compelling Stellarex DCB study results, we no longer need to compromise. In the most challenging patient population studied in a DCB Investigational Device Exemption trial, the next-generation Stellarex DCB achieved remarkable clinical outcomes. I am very excited these results could be obtained given the high proportion of severely calcified lesions and co-morbidities.”

The ILLUMENATE Pivotal Trial enrolled 300 patients, all of whom were randomized to treatment with the Stellarex DCB or a percutaneous transluminal angioplasty (PTA). This patient cohort represents the most complex patient population studied in a DCB IDE trial, when considering co-morbidities for the DCB arm included high rates of severe calcification (43.9%), diabetes (49.5%), renal insufficiency (18.0%), and cardiovascular disease (45.0%). The key results, per Kaplan-Meier survival estimates, at day 365 include:
• Primary patency was 82.3% for the DCB group and 70.9% for the PTA group.  
• Freedom from clinically-driven target lesion revascularization (CD-TLR) was 93.6% for the DCB group and 87.3% for the PTA group.
• The trial met its primary safety and effectiveness endpoints and demonstrated superiority to PTA on both.

The ILLUMENATE Pivotal Trial is the second randomized controlled trial to study the Stellarex DCB. The ILLUMENATE European Randomized Control Trial reported a 12-month Kaplan-Meier primary patency rate of 89.0% for the DCB arm vs. 65.0% in the PTA arm.  When the DCB cohort data from both randomized trials is pooled, the Kaplan-Meier primary patency rate is 86.0% and the CD-TLR rate is 94.2%.
 
 “Severe calcification has been viewed as the Achilles heel of drug-coated balloons. Our U.S. Pivotal Trial data provides compelling evidence that Stellarex achieves top-tier patency even in very complex patients. These outcomes are a significant step forward in our effort to improve patient care and lead the way in clinical science,” said Scott Drake, President and CEO.

The ILLUMENATE Pivotal Trial was conducted with the highest level of rigor to ensure accuracy and reliability of the data.  Independent, blinded third parties included a clinical events committee and angiographic and duplex ultrasound core laboratories to assess diagnostic images and outcomes.

As previously announced, the company will host a webcast to discuss the study results with Dr. Krishnan and Dr. Lyden at 10 a.m. Eastern Standard Time today.

About the Stellarex Drug-coated Balloon Platform
The Stellarex DCB platform is designed to treat peripheral arterial disease. The Stellarex DCB uses EnduraCoat™ technology, a durable, uniform coating designed to prevent drug loss during transit and facilitate controlled, efficient drug delivery to the treatment site. Spectranetics launched the device in Europe in January 2015. It is not available for sale in the U.S. Commercialization in the U.S. is anticipated in the second half of 2017.

About the ILLUMENATE Clinical Program
There are five ILLUMENATE clinical studies evaluating the safety and efficacy of the Stellarex DCB platform and support United States and Canadian regulatory filings. There are four ILLUMENATE clinical studies in addition to the ILLUMENATE Pivotal Trial described above:
• The ILLUMENATE First-In-Human (FIH) Study was a non-randomized, multi-center study that enrolled 80 patients. In the pre-dilatation arm (n=50), the primary patency rate at was 89.5% at 12 months and 80.3% at 24 months. 
• The ILLUMENATE Pharmacokinetic Study measured the Paclitaxel drug levels in the blood of 25 patients enrolled at two sites.
• The ILLUMENATE EU Randomized Trial is a prospective, randomized controlled, multicenter trial with 328 patients enrolled at 18 sites. The primary safety and effectiveness endpoints were met and superiority over • • PTA was demonstrated in both.  The 12-month primary patency rate was 89.0% vs. 65.0% in the PTA arm (p<0.001).  
• The ILLUMENATE Global study is a prospective, multi-center, single-arm study with 371 patients enrolled.  Interim data on the first 220 subjects showed a primary patency rate of 86.5% at 12 months.
