Abbott Receives FDA Approval for Expanded Indication for MitraClip(TM) Device
ABBOTT PARK, Ill., March 14, 2019 /PRNewswire/ -- Abbott (NYSE: ABT) today announced it received approval from the U.S. Food and Drug Administration (FDA) for a new, expanded indication to its leading MitraClip™ device used to repair a leaky mitral valve without open-heart surgery. Supported by the results of the landmark COAPT™ Trial, MitraClip is the first transcatheter mitral valve intervention therapy approved to treat select heart failure patients with clinically significant secondary, or functional, mitral regurgitation (MR).
The MitraClip transcatheter clip-based therapy, available in the U.S. since 2013 and now on a third generation of product innovations, has been used to treat more than 80,000 patients worldwide over the last 10 years. The new, expanded indication addresses the secondary form of MR and significantly increases the amount of people with MR able to be treated with MitraClip. Based on this approval, Abbott will begin discussions with the Center for Medicare and Medicaid Services (CMS) and physician specialty societies to request a revision to the national coverage determination (NCD) that would expand Medicare coverage to include secondary MR patients.
"Since severe secondary MR is extremely difficult to manage and associated with a poor prognosis, people have historically had few options," said Neil Moat, M.D., chief medical officer of Abbott's structural heart business. "The expanded indication of MitraClip opens new doors for these ailing patients and can improve their quality of life and chance of survival despite their complex condition."
Approximately four million Americans suffer from MR, specifically one in 10 adults age 75 and older.i,ii,iii,iv It's estimated two to three times as many patients may benefit from MitraClip treatment for secondary MR as a result of underlying heart failure than those treated for the primary (or degenerative) form of the disease associated with the structure of the valve.v People with heart failure may develop secondary MR when the left chamber of the heart becomes enlarged, preventing the mitral leaflets from closing normally and allowing blood to flow backwards through the heart.vi
Significant secondary MR can lead to reduced quality of life, recurrent hospitalizations and decreased survival.vii,viii Medication alone is the current standard of care for most heart failure patients with secondary MR, but this approach only helps manage the symptoms and does not address the underlying cause. MitraClip is now an effective treatment option for these ailing patients.
The MitraClip device repairs MR without open-heart surgery and is delivered to the heart through a small incision in the leg. The device clips portions of the leaflets, or flaps, of the mitral valve together to reduce the backflow of blood, restoring the heart's ability to pump oxygenated blood more efficiently. MitraClip provides almost immediate symptom relief and patients are released from the hospital on average after two days.
"Over the past decade, we have made significant and consistent investments to lead the development of novel treatments for mitral valve disease," said Michael Dale, vice president of Abbott's structural heart business. "The expanded indication for MitraClip is a direct result of the dedication of our employees as well as our remarkable clinical investigators."
Abbott is the global leader in developing transcatheter mitral valve technologies as alternatives to open-heart surgery. Building upon its success with the MitraClip device and many years of mitral valve experience and clinical evidence, Abbott is leading the way in novel, transcatheter devices by investing in the development of new mitral valve replacement options with its Tendyne and Cephea valve technologies.
About the COAPT Trial
The COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) Trial investigated MitraClip for treating secondary MR, and the data add to more than 10 years of evidence on the use of MitraClip for treating both primary and secondary MR. While the secondary MR indication has just been received in the U.S., the device has treated patients outside of the U.S. with both forms of the disease. COAPT met both primary and all 10 secondary endpoints as presented during the TCT cardiology meeting in Sept. 2018, showing a 47 percent relative reduction in hospitalizations and a 38 percent relative reduction in mortality.
The meaningful results showed that MitraClip was superior to medical therapy in reducing hospitalization and death for patients with severe secondary mitral regurgitation. In the COAPT Trial, 614 symptomatic heart failure patients with moderate-to-severe or severe secondary MR were randomized to receive treatment with MitraClip plus guideline-directed medical therapy or guideline-directed medical therapy alone at 78 sites in the U.S. and Canada. The primary efficacy endpoint was all heart failure hospitalizations through two years, and the primary safety endpoint was freedom from device-related complications at one year compared to a performance goal of 88 percent.
