Availability of the two-lead device represents a significant advancement in the development of cardiac contractility modulation therapy for patients with heart failure

MT. LAUREL, N.J.– April 14, 2020 – Impulse Dynamics, a medical device company dedicated to improving the lives of heart failure patients, today announced the publication of the FIX-HF-5C2 study in Circulation: Heart Failure. The study affirms the safety and efficacy of the company’s 2-lead version of the Optimizer® system, which was approved by the FDA in October 2019.

The prospective, multicenter, single-arm study was designed to evaluate the performance, safety and efficacy of the 2-lead Optimizer system. The study confirmed the 2-lead version of the device is just as effective at delivering CCM™ (cardiac contractility modulation) therapy as the 3-lead version and by eliminating the atrial lead, patients experienced significantly fewer device-related complications when compared to the 3-lead version. Patients that received the 2-lead version had a significantly greater improvement in exercise capacity (as measured by peak VO2) and functional status (as measured by New York Heart Association functional class) when compared to the FIX-HF-5C control group. Additionally, 15% of the patients enrolled in the FIX-HF-5C2 study had atrial fibrillation.

“The publication of this data confirms that the 2-lead device is a significant advancement for how we can provide CCM therapy to heart failure patients,” said Ishu Rao, M.D., Medical Director for Impulse Dynamics. “Notably, the data shows that CCM therapy has a substantial positive impact on a patient’s functional capacity over time versus standard medical care alone. There has been tremendous excitement from patients and providers for the 2-lead Optimizer system and we look forward to continuing to expand the adoption of this breakthrough treatment option.”

The FIX-HF-5C2 study was a confirmatory extension of the FIX-HF-5C randomized study and enrolled heart failure patients from eight medical centers in the U.S. and Germany. Patients were evaluated at baseline and again at 12 and 24 weeks after implantation.

“The 2-lead version of the Optimizer system is an important evolution that reduces lead-related complications and simplifies the implantation procedure,” said Phi Wiegn, M.D., of the Dallas VA Medical Center and lead author of the publication. “CCM is a truly unique device therapy that I can offer to a large group of heart failure patients to make them feel better when standard medical therapy no longer does.”

CCM therapy may be an appropriate treatment option for the approximately 70 percent of NYHA Class III heart failure patients who remain symptomatic despite guideline-directed medical therapy..1

About the Optimizer® and CCM® Therapy

The Optimizer Smart system delivers CCM therapy — the company’s proprietary technology — to the heart. CCM therapy has been designed by Impulse Dynamics to significantly improve the heart’s contraction, allowing more oxygen-rich blood to be pushed out through the body. CCM therapy is indicated to improve the 6-minute hall walk, quality of life, and functional status of NYHA Class III heart failure patients who remain symptomatic despite guideline-directed medical therapy, are not indicated for CRT, and have a left ventricular ejection fraction ranging from 25 to 45 percent.

CCM is the brand name for cardiac contractility modulation — the non-excitatory electrical pulses delivered by the implantable Optimizer device to improve heart contraction. CCM therapy sends unique electrical pulses to the heart cells during the absolute refractory period. In doing so, CCM helps the heart contract more forcibly. Impulse Dynamics has completed numerous clinical studies, including several randomized controlled trials, and CCM therapy has been published in more than 120 peer-reviewed journal articles.

About Impulse Dynamics

Impulse Dynamics is dedicated to advancing the treatment of heart failure for patients and the healthcare providers who care for them. The company pioneered its proprietary CCM therapy, which uses the Optimizer platform to improve quality of life in heart failure patients. CCM therapy is delivered through the Optimizer system, which includes an IPG implanted in a minimally invasive procedure and approved for commercial use in the United States and 44 countries worldwide. CCM therapy has proven safe and effective for heart failure patients with debilitating symptoms who otherwise have few effective options available to them.
