COLORADO SPRINGS, Colo., Feb. 24, 2014 (GLOBE NEWSWIRE) -- The Spectranetics Corporation (Nasdaq:SPNC) today announced that the EXCITE ISR trial achieved the statistical endpoints of the adjunct analysis. The trial evaluates laser atherectomy plus Percutaneous Transluminal Angioplasty (PTA) compared with PTA alone for the treatment of in-stent restenosis (ISR) in patients suffering from peripheral artery disease (PAD).
The company anticipates submitting the 510(k) application to the FDA in the next 45 days. FDA review of a 510(k) application with clinical data takes an average of five months.
The EXCITE adjunct analysis, which was approved by the FDA in May 2013, allowed for multiple interim data analyses during the randomized trial. Statistical success was achieved based on enrollment of 250 patients at 35 sites across the U.S.
Spectranetics designed this treatment-to-control trial to show safety and effectiveness of treatment with laser atherectomy. Freedom from target lesion revascularization (TLR) at six months was hypothesized to be 70% in the laser atherectomy plus PTA arm and 53% for PTA alone to prove statistical superiority. This benchmark was exceeded, which demonstrated early success.
"This is an important milestone for our company and for patients worldwide," said Scott Drake, President and Chief Executive Officer. "Patients who suffer from PAD and the physicians who treat them deserve a proven, durable treatment algorithm. Keys to unlocking this $750M market opportunity include obtaining the ISR indication, practice-changing clinical data and excellent commercial execution. Our primary competitors are contraindicated for ISR, making us uniquely positioned on all fronts."
According to Dr. Eric J. Dippel M.D., Genesis Medical Center, Iowa, and primary investigator, "EXCITE is a landmark randomized, controlled trial that represents a major step forward in treating patients with ISR. This is a very large patient population that has suffered from insufficient, unproven treatment for too long."
The trial's largest enroller, Dr. Satyaprakash Makam M.D., Cardiovascular Research of Northwest Indiana, states, "Many ISR patients are in poor health. Stent replacement is not an option, and balloon angioplasty sometimes lasts just weeks. The data from this trial has the power to change clinical practice and improve patient care in this challenging disease state."
About EXCITE ISR
The EXCITE ISR trial was designed to enroll a maximum of 318 subjects at up to 35 sites, randomized 2:1 treatment to control. The treatment arm is laser atherectomy combined with PTA and the control arm is PTA alone. The primary efficacy endpoint is freedom from TLR through six months. The primary safety endpoint is freedom from major adverse events (MAEs) at 30 days. MAEs include all-cause mortality, major amputation in the target limb, or TLR. The goal of the adjunct analysis plan was to demonstrate statistically significant clinical superiority of laser atherectomy plus PTA compared with PTA alone prior to full enrollment of the EXCITE ISR trial.
PTA, also known as balloon angioplasty, is a minimally invasive procedure used to open blocked or stenosed blood vessels. A balloon catheter is placed at the blockage site and inflated to compress the blockage against the vessel wall. While PTA tends to be a temporary solution, it is considered the standard of care for patients with stenosis, a narrowing of the blood vessels in the leg due to PAD, or restenosis, a recurrence of a blockage following treatment. When a stent is used and restenosis occurs, ISR can develop.
Spectranetics develops, manufactures, markets and distributes single-use medical devices used in minimally invasive procedures within the cardiovascular system. The Company's products are sold in over 40 countries and are used to treat arterial blockages in the heart and legs, and the removal of pacemaker and defibrillator leads.
The Company's Vascular Intervention (VI) products include a range of laser catheters for ablation of blockages in arteries above and below the knee. The Company also markets support catheters to facilitate crossing of peripheral and coronary arterial blockages, and retrograde access and guidewire retrieval devices used in the treatment of peripheral arterial blockages, including chronic total occlusions. The Company markets aspiration and cardiac laser catheters to treat blockages in the heart.
The Lead Management (LM) product line includes excimer laser sheaths, mechanical sheaths and accessories for the removal of pacemaker and defibrillator cardiac leads.
