Neovasc Inc.'s Tiara Transcatheter Mitral Valve Selected as a "Best" New Device Concept at TCT 2012 Scientific Symposium
Published: Oct 23, 2012
"This has been a very positive meeting for Neovasc as we continue to generate positive data that support the advancement of both the Tiara transcatheter mitral valve program and the Reducer, our device-based therapy for patients with refractory angina," noted Alexei Marko, CEO of Neovasc. "Early Registry data for the Reducer confirm that patients exhibit significant, measurable clinical benefits post-implantation, and the Tiara program is generating a great deal of interest as the successful completion of our acute preclinical testing has enabled us to begin long-term animal safety studies. If all goes well, we anticipate Tiara human trials will commence in 2013."
The Tiara program is a novel solution to treat mitral valve regurgitation, a serious and poorly served condition affecting millions of cardiac patients. Current treatment options are limited since conventional surgical treatments are only appropriate for a small percentage of these patients. Tiara is intended to provide a minimally invasive transcatheter replacement for the mitral valve.
In the Tiara presentation, researchers concluded that initial preclinical experience with the Tiara mitral valve was encouraging and that implantation was feasible, relatively straightforward and has resulted in a securely-implanted, well-functioning device that maintained good hemodynamics in the test animals.
They reported that during these acute animal studies, the Tiara valves were implanted successfully in 81% of the test animals, with total procedure times ranging from 17 to 26 minutes. In the successful implantations, angiographic and echo imaging demonstrated excellent function of the Tiara device, with no obstruction of the left ventricular outflow tract, no pericardial effusion, no encroachment on the aortic valve, no transvalvular gradients and most importantly, no significant paravalvular leak. Researchers also reported early results from the first long-term animal implantations of the Tiara device, including echocardiogram images of Tiara valves obtained approximately three months after implant, which demonstrated continuing good function and integrity of the valve. These chronic animal studies are ongoing.
At TCT 2012, researchers are also presenting new data on the Neovasc Reducer, a novel device designed to treat the millions of patients worldwide who suffer from refractory angina, a painful and debilitating condition that occurs when the coronary arteries deliver an inadequate supply of blood to the heart muscle. The Reducer is intended to provide relief of refractory angina symptoms by altering blood flow through the myocardium, thereby increasing perfusion of oxygenated blood to ischemic areas of the heart. Placement of the Reducer is performed using a percutaneous procedure that is similar to implanting a coronary stent.
The Reducer has received a CE mark designation in Europe for the treatment of refractory angina, and patients are presently being enrolled in two open-label, multicenter, non-randomized, prospective Registries (REDUCE-1 and REDUCE-2) to collect additional clinical data on the product. Neovasc is also enrolling patients in the COSIRA trial, a sham-controlled, randomized, double-blinded study designed to further demonstrate the efficacy of the Reducer and to support additional regulatory applications.
The Neovasc researchers reported on the experience of the first 11 patients who were implanted with the Reducer and followed for six months or more as part of the REDUCE-1 and REDUCE-2 Registries. No complications or cardiac adverse events were recorded in these patients. Clinical parameters including the patients' angina scores and their daily consumption of nitroglycerin were diminished significantly six months after Reducer implantation. Additionally, exercise stress test parameters improved, and functional imaging of myocardial perfusion showed that blood flow in the heart improved significantly. Measures of left ventricular ejection fraction, considered a key indicator of cardiac function, also improved after Reducer implantation.
Dr. Shmuel Banai, lead author of the study and Medical Director of Neovasc, commented, "These preliminary results from the REDUCE Registries further confirm that implantation of the Reducer in patients with refractory angina is safe and simple to perform. We are encouraged that these patients are demonstrating improvement on multiple objective parameters of cardiac function six months after implantation. We look forward to analyzing additional data from the Registries and from the COSIRA trial, which we expect to complete in 2013."
