Neovasc REDUCER-I Study Published in EuroIntervention Journal

VANCOUVER and MINNEAPOLIS – (NewMediaWire) – September 28, 2021 – Neovasc Inc. (“Neovasc” or the “Company”) (NASDAQTSX: NVCN) today announced the publication of an article entitled, “Coronary sinus narrowing for the treatment of refractory angina: a multicentre prospective open-label clinical study (the REDUCER-I study)” in the September 2021 issue of the journal EuroIntervention.

The article’s lead authors are Stefan Verheye, MD, PhD, Cardiovascular Center, ZNA Middelheim Hospital, Antwerp, Belgium, and Maayan Konigstein, MD, from the Tel Aviv Medical Center, Tel Aviv, Israel. The publication provides interim results from the REDUCER-I study investigating patients suffering from refractory angina treated with the Neovasc Reducer™ (“Reducer”) system. The REDUCER-I study is a prospective, open-label, multi-center, international, post-market study, (with a retrospective component) which collects long-term data of patients with refractory angina treated with the Reducer. The publication outlines the overall clinical outcomes of the first 228 patients enrolled.

The primary efficacy endpoint was the percentage of patients who experience improvement in their angina symptoms defined as a reduction in Canadian Cardiovascular Society (“CCS”) grade, a measure of their disability, at six months as compared to baseline. The primary safety endpoints are the rate of occurrence of device- and/or procedure-related periprocedural serious adverse events, and major adverse cardiac events (“MACE”), a composite of cardiac death, major stroke and myocardial infarction up to 30 days post implant.

In the first 228 patients (81% male, 68.3±9.6 years), the procedural success rate was very high (99%), with a very high safety profile that translated to only one adjudicated possible procedural or device-related MACE. Mean CCS class improved from 2.8±0.6 at baseline, to 1.8±0.7 at two years. Improvement in ≥1 CCS class was observed in 82%, and in ≥2 CCS classes in 31% of patients at two years. At baseline, 70% of the cohort were disabled at very minimal physical effort (reported to be in CCS class III-IV); this portion was reduced to only 15% at follow-up. Additional measured parameters of functional class and quality of life were also improved. 

“The data published in the REDUCER-I study confirm the high safety profile of the therapy in patients suffering from refractory angina. The results also demonstrate sustained improvement in angina severity and in quality of life up to two years,” said Prof. Verheye. “I am encouraged that we now have a therapy to offer patients whom, in the past, had no treatment options. In properly selected patients, the Reducer offers hope for a return to a more normal life that is less hampered by the debilitating symptoms of refractory angina.” 

An accompanying editorial, “Coronary sinus reducer therapy for refractory angina: is it ready for prime time?” was published in the same issue of EuroIntervention. Authored by Dr. Michael Foley, MBBS, BSc and Dr. Rasha Al-Lamee, MBBS, MA, PhD, both from National Heart and Lung Institute, Imperial College London, United Kingdom, the editorial states, “The most important additive finding of REDUCER-I is the real-world procedural success and safety of a new device.” The authors further suggest that the ongoing ORBITA-COSMIC study and the upcoming COSIRA-II trial will be helpful to validate the Reducer device for an “important and often overlooked clinical group.”

“Publication of the interim results of REDUCER-I is another meaningful step as we build the evidence necessary to establish the Reducer as standard of care for patients suffering from refractory angina,” stated Fred Colen, President & Chief Executive Officer of Neovasc. “We are encouraged by the peer-reviewed clinical data that continues to mount supporting Reducer therapy as a viable treatment option for patients that are suffering from angina-related chest pain. It’s gratifying to see so many patients be able to return to the daily living activities that they have previously avoided.”

About Reducer

The Reducer is CE-marked in the European Union and Under Investigation in the United States for the treatment of refractory angina, a painful and debilitating condition that occurs when the coronary arteries deliver an inadequate supply of blood to the heart muscle, despite treatment with standard revascularization or cardiac drug therapies. It affects millions of patients worldwide, who typically lead severely restricted lives as a result of their disabling symptoms, and its incidence is growing. The Reducer provides relief of angina symptoms by altering blood flow within the myocardium of the heart and increasing the perfusion of oxygenated blood to ischemic areas of the heart muscle. Placement of the Reducer is performed using a minimally invasive transvenous procedure that is similar to implanting a coronary stent and can be completed in approximately 20 minutes.   

While the Reducer is not approved for commercial use in the United States, the FDA granted Breakthrough Device designation to the Reducer in October 2018. 

Refractory angina, resulting in continued symptoms despite maximal medical therapy and without revascularization options, is estimated to affect 600,000 to 1.8 million Americans, with 50,000 to 100,000 new cases per year.
