Brief Summary

The purpose of the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) Trial is to confirm the safety and effectiveness of the MitraClip System for the treatment of moderate-to-severe or severe functional mitral regurgitation (FMR) in Symptomatic Heart Failure Subjects who are treated per standard of care and who have been determined by the site's local heart team as not appropriate for mitral valve surgery. This randomized controlled trial will provide the opportunity to strengthen or add labeling claims regarding safety and clinical benefits of the MitraClip System for symptomatic heart failure patients with moderate-to-severe or severe functional mitral regurgitation. Approximately 610 subjects will be randomized at up to 100 investigational sites with approximately 305 subjects targeted to receive the study device. COAPT study completed recruiting subjects in June 2017. As part of the COAPT trial, a subset of patients will be registered in the cardiopulmonary exercise (CPX) sub-study. The objective of this sub-study is to evaluate the exercise responses in a sub-cohort of COAPT subjects who receive MitraClip device (Device group) compared to the Control group who do not receive MitraClip device. (Note: the CPX Sub-study subjects will contribute to the analyses of the COAPT primary and secondary endpoints) As an extension of the COAPT RCT trial, COAPT CAS study will be conducted after COAPT enrollment is complete under the same investigational device exemption (IDE(G120024)). The objective of this study is to evaluate the MitraClip® NT System for the treatment of clinically significant functional mitral regurgitation (FMR) in symptomatic heart failure subjects who are treated per standard of care and who have been determined by the site's local heart team as not appropriate for mitral valve surgery. The anticipated Study Completion Date is July 2024. COAPT CAS completed recruiting subjects in March 2019.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Symptomatic functional MR (≥3+) due to cardiomyopathy of either ischemic or non-ischemic etiology determined by assessment of a qualifying transthoracic echocardiogram (TTE) obtained within 90 days and transesophageal echocardiogram (TEE) obtained within 180 days prior to subject registration, with MR severity based principally on the TTE study, confirmed by the Echocardiography Core Lab (ECL). The ECL may request a transesophageal echocardiogram (TEE) to confirm MR etiology.
  • Note: Functional MR requires the presence of global or regional left ventricular wall motion abnormalities, which are believed to be the primary cause of the MR. If a flail leaflet or other evidence of degenerative MR is present, the subject is not eligible even if global or regional left ventricular systolic dysfunction is present.
  • Note: Qualifying TTE must be obtained after the subject has been stabilized on optimal therapy including Guideline Directed Medical Therapy (GDMT) and at least 30 days after:
  • a greater than 100% increase or greater than 50% decrease in dose of GDMT
  • revascularization and/or implant of Cardiac Resynchronization Therapy device (CRT or CRT-D) or reprogramming of an implanted CRT or CRT-D that results in increased biventricular pacing (from \<92% to ≥92%)
  • In the judgment of the HF specialist investigator at the site, the subject has been adequately treated per applicable standards, including for coronary artery disease, left ventricular dysfunction, mitral regurgitation and heart failure (e.g., with cardiac resynchronization therapy, revascularization, and/or GDMT). The Eligibility Committee must also concur that the subject has been adequately treated.
  • New York Heart Association (NYHA) Functional Class II, III or ambulatory IV.
  • The Local Site Heart Team (CT surgeon and HF specialist investigators) and the Central Eligibility Committee concur that surgery will not be offered as a treatment option and that medical therapy is the intended therapy for the subject, even if the subject is randomized to the Control group.
  • The subject has had at least one hospitalization for heart failure in the 12 months prior to subject registration and/or a corrected brain natriuretic peptide (BNP) ≥300 pg/ml or corrected n-Terminal pro- brain natriuretic peptide NT-proBNP ≥1500 pg/ml measured within 90 days prior to subject registration ("corrected" refers to a 4% reduction in the BNP or NT-proBNP cutoff for every increase of 1 kg/m2 in BMI above a reference BMI of 20 kg/m2).
  • Note: BNP or NT-proBNP must be obtained after the subject has been stabilized on GDMT and at least 30 days after:
  • a greater than 100% increase or greater than 50% decrease in dose of GDMT
  • revascularization and/or implant of Cardiac Resynchronization Therapy device (CRT or CRT-D) or reprogramming of an implanted CRT or CRT-D that results in increased biventricular pacing (from \<92% to ≥92%).
  • Left Ventricular Ejection Fraction (LVEF) is ≥20% and ≤50% within 90 days prior to subject registration, assessed by the site using any one of the following methods: echocardiography, contrast left ventriculography, gated blood pool scan or cardiac magnetic resonance imaging (MRI).
  • Note: The method must provide a quantitative readout (not a visual assessment).
  • The primary regurgitant jet is non-commissural, and in the opinion of the MitraClip implanting investigator can be successfully be treated by the MitraClip. If a secondary jet exists, it must be considered clinically insignificant.
  • +7 more criteria

You may not qualify if:

  • Chronic Obstructive Pulmonary Disease (COPD) requiring continuous home oxygen therapy or chronic outpatient oral steroid use.
  • Untreated clinically significant coronary artery disease requiring revascularization.
  • Coronary artery bypass grafting (CABG) within 30 days prior to subject registration.
  • Percutaneous coronary intervention within 30 days prior to subject registration.
  • Transcatheter aortic valve replacement (TAVR) within 30 days prior to subject registration.
  • Tricuspid valve disease requiring surgery or transcatheter intervention.
  • Aortic valve disease requiring surgery.
  • Cerebrovascular accident within 30 days prior to subject registration.
  • Severe symptomatic carotid stenosis (\> 70% by ultrasound).
  • Carotid surgery or stenting within 30 days prior to subject registration.
  • American College of Cardiology /American Heart Association (ACC/AHA) Stage D heart failure.
  • Presence of any of the following:
  • Estimated pulmonary artery systolic pressure (PASP) \> 70 mm Hg assessed by site based on echocardiography or right heart catheterization, unless active vasodilator therapy in the cath lab is able to reduce the pulmonary vascular resistance (PVR) to \< 3 Wood Units or between 3 and 4.5 Wood Units with v wave less than twice the mean of the pulmonary capillary wedge pressure
  • Hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, or any other structural heart disease causing heart failure other than dilated cardiomyopathy of either ischemic or non ischemic etiology
  • Infiltrative cardiomyopathies (e.g., amyloidosis, hemochromatosis, sarcoidosis)
  • +26 more criteria
