Study assessing efficacy of Neovasc Reducer for treatment of Refractory Angina published in NEJM

Neovasc Inc. ("Neovasc" or the "Company") (NASDAQ: NVCN) (TSX: NVC) today announced that the final results from its COSIRA study assessing the efficacy and safety of the Neovasc Reducer™ for treatment of Refractory Angina, were published today in the New England Journal of Medicine ("NEJM").

Refractory Angina ("RA") is a debilitating disease involving chronic chest pain and affecting millions of patients worldwide who have limited treatment options. The COSIRA study met its primary endpoint, demonstrating the efficacy of the Reducer in relieving angina symptoms in these patients.

"It is important to emphasise that these RA patients are severely restricted in their daily living due to chronic, debilitating chest pain. Even simple activities such as standing up or walking a small distance from one room to another can be difficult to perform," said Dr. Stefan Verheye, Senior Interventional Cardiologist at the Antwerp Cardiovascular Center/ZNA Middelheim and Principal Investigator of the COSIRA trial. "Previously faced with virtually no effective treatment options, these positive results clearly illustrate that the Reducer has the potential to transform the lives of millions of patients. Add to this fact that implanting the Reducer is a straightforward procedure that can be easily adopted into medical practice. It is similar to implanting a coronary artery stent, which happens thousands of times every day."

"The results from this rigorously designed trial speak for themselves. They demonstrate a clear clinical benefit and highly safe procedure," said Dr. Shmuel Banai, Director of Interventional Cardiology in the Cardiology Department at the Tel Aviv Medical Center, Tel Aviv, Israel. "For RA patients, even a 1-grade improvement in CCS class makes a dramatic impact on their quality of life, let alone a 2-grade improvement, which occurred in 35% of the treated patients."

The Canadian Cardiovascular Society ("CCS") angina grading scale is a four-class functional classification that is widely used to characterize the severity of angina symptoms and disability. Only patients with severe angina, CCS Class 3 or 4, were enrolled in the COSIRA trial.

"The acceptance of the COSIRA data for publication in one of the most respected peer-reviewed medical journals underscores the medical community's recognition of the pressing need that RA represents and the high-level of interest for new therapies to effectively treat the condition," said Alexei Marko, CEO of Neovasc. "We expect commercial distribution of the Reducer in selected European markets to begin shortly and we are also working to advance the Reducer's clinical and regulatory program in the US."

Trial Highlights
The COSIRA data demonstrates that patients treated with the Reducer achieved a statistically significant improvement in CCS angina grading scale scores (two classes or better) compared to those patients in the sham control arm, (p-value = 0.024). Patients treated with the Reducer were 2.3 times more likely to see an improvement of two classes or better in CCS score than the sham control arm. The analysis also demonstrated that patients treated with the Reducer showed a statistically significant improvement of one or more CCS classes compared to the sham control patients (p-value = 0.003). The study also demonstrated a 96.2% technical success rate and a 100% procedural success rate for Reducer implantation.
