Description

Summary

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 ≤60%.

Official Title

Assessment of Implantable CCM in the Heart Failure Group With Higher Ejection Fraction

Details

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.
