A Clinical Evaluation of the Safety and Effectiveness of the MitraClip System in the Treatment of Clinically Significant Functional Mitral Regurgitation (Reshape-HF2)

This is an interventional treatment trial for Mitral Valve Insufficiency Read More

Key Inclusion Criteria:

• Clinically significant functional mitral regurgitation (moderate-to-severe or severe MR) as defined by European Association of Echocardiography, within 90 days prior to randomization and confirmed by the Echocardiography Core Laboratory Note: The TTE must be obtained after the subject has been stabilized on optimal therapy and has undergone revascularization and/or CRT, as appropriate
• Assessed by the investigator to be on optimal standard of care therapy for heart failure, according to current ESC/HFA guidelines with no dose changes of heart failure drugs (with the exception of diuretics) during the last 2 weeks immediately prior to randomization.
• Symptomatic with documented New York Heart Association Class II, III or IV heart failure, despite optimal standard of care therapy, within 30 days preceding randomization
• Minimum of one documented hospitalization (acute care admission or emergency room visit) for heart failure within 12 months preceding randomization OR values of 300 pg/mL for BNP or 1000 pg/mL for NT-proBNP after optimal medical and/or device management within 90 days preceding randomization Note: BNP or NT-proBNP must be obtained after the subject has been stabilized on optimal therapy and has undergone revascularization and/or CRT, as appropriate
• Left ventricular ejection fraction (LVEF) of ≥ 15% to ≤ 35% (if in NYHA Functional Class II) or of ≥ 15% to ≤ 45% (if in NYHA Functional Class III or IV).

Note: LVEF needs to be determined by one of the following methods: transthoracic echocardiography (TTE), contrast ventriculography, gated blood pool scan, cardiac magnetic resonance) within 90 days prior to randomization

- Patient is ambulatory and able to perform a 6MWT with the only limiting factor(s) being due to cardiovascular fitness

Key Exclusion Criteria:

• Mitral regurgitation is primarily due to degenerative disease of the mitral valve apparatus (Degenerative MR) as determined by transesophageal echocardiography (TEE).
• Status 1 heart transplant or prior orthotropic heart transplantation.
• Introduction of a new heart failure drug class within the last 2 weeks prior to randomization.
• Evidence of acute coronary syndrome, transient ischemic attack or stroke within 90 days prior to randomization.
• Any percutaneous cardiovascular intervention, carotid surgery, cardiovascular surgery, or atrial fibrillation ablation within 90 days prior to randomization.
• Therapy with or without cardioverter-defibrillator (CRT or CRT-D), or Implantable Cardioverter Defibrillator (ICD)) within 90 day prior to randomization, or revision of any implanted rhythm management device within 90 days prior to randomization.
• Need for any cardiovascular surgery.
• Mitral valve surgery is considered the preferred therapeutic option for the subject
• Renal replacement therapy
• 6-Minute Walk Test (6MWT) distance > 475 meters
• Mitral Valve Area (MVA) by planimetry < 4.0 cm2; if MVA by planimetry is not measurable, pressure half-time measurement is acceptable; MVA must be confirmed by the Echocardiography Core Laboratory
