Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: FIX-HF-5CA: Continued Access Protocol for the Evaluation of the OPTIMIZER Smart System in Subjects With Moderate-to-Severe Heart Failure With Ejection Fraction Between 25% and 45%
Actual Study Start Date : July 1, 2017
Actual Primary Completion Date : November 29, 2019
Actual Study Completion Date : November 29, 2019

Arm Intervention/treatment
Experimental: Optimizer Smart System
All eligible subjects will have the Optimizer Smart System implanted and receive cardiac contractility modulation therapy (CCM).
Device: Optimizer Smart System
The Optimizer Smart System delivers non-excitatory cardiac contractility modulating (CCM) electrical signals to the heart muscle. Treatment group subjects receive five non-contiguous one-hour periods of CCM signals per day.

Primary Outcome Measures :
  1. SADEs [ Time Frame: 6 Months ]
    Serious Adverse Device Events

Secondary Outcome Measures :
  1. KCCQ [ Time Frame: 6 Months ]
    Kansas City Cardiomyopathy Questionnaire

  2. NYHA [ Time Frame: 6 Months ]
    New York Heart Association classification
