July 11, 2014 — DC Devices Inc. has closed a $34 million Series D financing round. Accelmed led the round with contributions from existing investors Third Rock Ventures, General Catalyst Partners and Lumira Capital, as well as a new undisclosed strategic investor. Funds will be used to complete clinical evaluation of the world’s first transcatheter device for the treatment of diastolic heart failure (DHF), a $5 billion global market opportunity.
With heart failure representing the single-biggest cause of hospitalizations in many countries, and the largest expense in the U.S. Medicare budget, new therapies that reduce the heart failure hospitalization rate and improve patients’ quality of life are needed.
The company’s proprietary, minimally invasive InterAtrial Shunt Device (IASD) system is the world’s first device intended to treat DHF, also known as heart failure with preserved ejection fraction (HFpEF). By placing a permanent implant in the atrial septum, the IASD System is designed to reduce elevated left atrial pressure and relieve symptoms. The innovative IASD System allows physicians to perform this transcatheter treatment without open-heart surgery and in a controlled fashion, using standard interventional cardiology techniques.
“Patients who suffer from diastolic heart failure have no effective treatment options and have a poor survival rate,” said George Fazio, president and CEO of DC Devices. “With the support of our investors and the guidance of our clinical advisors, we are now one step closer to bringing a potentially transformative new therapy to heart failure patients around the world.”
The DC Devices clinical advisory board is comprised of a group of international, multi-specialty, leading physicians who bring a broad range and depth of expertise to the company. The advisory board, which provides medical and strategic guidance for product development, clinical, and commercialization activities, includes Drs. Martin Leon, Gerd Hasenfu?, Sanjiv Shah, David Kaye, Piotr Ponikowski, Daniel Burkhoff, Ted Feldman, Laura Mauri, Matthew Maurer, John Cleland and Barry Borlaug among others.
