Inclusion Criteria

  1. Signed and dated informed consent form; 2. Male or non-pregnant female, 18 years or older; 3. Diagnosed with symptomatic heart failure; 4. LVEF ≥40 and ≤60% (as assessed by echo core lab); 5. A. Heart failure hospitalization within 12 months prior to study consent OR an urgent heart failure visit requiring IV therapy within 6 months prior to study consent, AND elevated BMI-adjusted natriuretic peptide values (Refer to Table A in Section 9.2.6) OR B. If there is no heart failure hospitalization within 12 months prior to study consent OR an urgent heart failure visit requiring IV therapy within 6 months prior to study consent, an elevated BMI-adjusted natriuretic peptide value must be achieved (Refer to Table B in Section 9.2.6) 6. Subjects must be on stable, scheduled oral loop diuretic treatment (not only PRN) for at least 30 days prior to study consent, unless documented allergy/intolerance. Note: Stable is defined as no more than a 100% increase or 50% decrease in dose within the last 30 days. A one-time hold of diuretic dosing for 24 hours during the 30-day period is allowed and not an exclusionary event.

Exclusion Criteria

  1. Resting ventricular rate <50 or >110 bpm; 2. Resting systolic blood pressure <100 or ≥160 mmHg; 3. BMI greater than 46 4. Any severe valvular stenotic disease or any severe valvular regurgitation; 5. Mechanical tricuspid valve; 6. Complex congenital heart disease; 7. Exercise tolerance limited by a condition other than heart failure that, in the opinion of the investigator, contributes significantly to the primary symptoms of shortness of breath and/or exercise intolerance; 8. Unable to walk at least 100 meters or walks more than 450 meters during a 6MWT; 9. A KCCQ CCS score higher than 85; 10. Hypertrophic, infiltrative/restrictive or inflammatory cardiomyopathy; 11. Unstable angina pectoris within 30 days prior to study consent; 12. Acute, decompensated heart failure requiring IV therapy or ultrafiltration within 30 days prior to consent, in the hospital or an outpatient setting; 13. Receiving cardiac resynchronization therapy (CRT); 14. Scheduled for a cardiac surgery or a percutaneous cardiac intervention (PCI) or have undergone cardiac surgery within 90 days or a PCI procedure within 30 days prior to study consent; 15. Myocardial infarction within 90 days prior to study consent; 16. Prior heart transplant or ventricular assist device; 17. Planning to become pregnant during the study; 18. Dialysis (permanent) or GFR <20 ml/min/1.73m2; 19. Participating in another investigational study; 20. Currently undergoing active chemotherapeutic and/or radiation treatment for cancer or has a history of chemotherapy during the 2-year period prior to study consent; 21. Expected lifespan of less than 18 months from time of study consent;

In addition to the subject, the entire site research team, the implanting physician, the Clinical Events Committee (CEC), and the clinical study monitors will all be blinded to the treatment assignment. Site research staff and Impulse Dynamics monitoring personnel will not have viewing rights to the randomization assignment.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
CCM Group (CCM ON)
CCM therapy will be turned on in 2/3 of the subjects for the entire duration of the study.
  • Device: Cardiac Contractility Modulation Therapy via OPTIMIZER™ Smart Mini System
    The OPTIMIZER™ Smart Mini System will be implanted and CCM will be programmed ON for the first 18 months (blinded phase). CCM therapy will be programmed to deliver 7 one-hour phases of CCM therapy that are distributed equally over every 24-hour period. CCM will remain on following completion of the 18-month visit.
    Other names:
    • CCM Group (CCM ON)
Sham Comparator
Sham Group (CCM OFF)
CCM therapy will be turned off in 1/3 of the subjects for the first 18 months of the study. After 18 months, CCM therapy will be turned on for the rest of the study duration.
  • Device: OPTIMIZER™ Smart Mini System
    The OPTIMIZER™ Smart Mini System will be implanted and CCM will be programmed OFF for the first 18 months (blinded phase). CCM will be turned on following completion of the 18-month visit.
    Other names:
    • Sham Group (CCM OFF)

Detailed Description

The AIM HIGHer Clinical Trial is a prospective, multi-center, randomized, quadruple-blind, sham-controlled, two-part embedded trial of the safety and efficacy of CCM therapy delivered via the OPTIMIZER Smart Mini System in subjects with heart failure and an LVEF ≥40% and ≤60%. Subjects will be enrolled at approximately 150 sites in the US and 75 sites OUS. All subjects will undergo screening and baseline testing; all eligible subjects will be implanted with the Optimizer System. Subjects will be randomized in a 2:1 ratio to either CCM ON (CCM group) or to CCM OFF (Sham group). The trial will be blinded to the treatment assignment of the device for 18-months. Subjects in the Sham group will have CCM turned ON after completion of the 18-month study visit. Subjects enrolled during Part I (450 subjects) of the trial will continue follow-up through the end of Part II (up to an additional 1,050) and contribute data to both parts of the trial. Each part of the trial is distinguished by a separate scientific purpose. The specific purpose of each part is: Part I - Establish safety and effectiveness based on functional capacity and health status. Part II - Establish safety and effectiveness based on clinical outcome data.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health).
