Assessment of CCM in HF With Higher Ejection Fraction

Sponsored by Impulse Dynamics

About this study

The AIM HIGHer Clinical Trial will evaluate the safety and efficacy of Cardiac Contractility Modulation (CCM) therapy in patients with heart failure with LVEF ≥40% and ≤70%.

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 ≤70%. 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 (45…

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 ≤70% (as assessed by site echo);
  • ✓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 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 1 in Section 9.2.6)
  • ✓6. Subjects must meet one of the following conditions:
  • ✓Have stable, scheduled oral loop diuretic treatment (not just PRN) for a minimum of 30 days before providing study consent unless there is a documented allergy or intolerance.
  • ✓Eligibility for enrollment is maintained for patients on an SGLT2 inhibitor without prescribed concurrent standing loop diuretic therapy if investigators provide instructions for a flexible PRN diuretic regimen (deemed appropriate by the clinician in response to symptoms or weight gain) 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.

  • ✕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 \<15 ml/min/1.73m2;
  • ✕19. Participating in another investigational drug or device study that may interfere with the interpretation of study data;
  • ✕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;
