Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Subjects who are 18 years of age or older
  • Subject is male or a non-pregnant female
  • Subjects who have a baseline ejection fraction greater than or equal to 25% and less than or equal to 45% by echocardiography determined by the echocardiography core laboratory.
  • Subjects who have been treated for heart failure for at least 90 days (including treatment with a β-blocker for at least 90 days unless the subject is intolerant) and are in New York Heart Association functional Class III and IV at the time of enrollment.
  • Subjects receiving appropriate, stable medical therapy during the 30 days prior to enrollment for treatment of heart failure according to guideline recommendations. For patients with EF≤35%, this regimen shall consist of the appropriate doses of diuretics, ACE-inhibitor or angiotensin II receptor blocker and β-blocker. Angiotensin receptor -neprilysin inhibitor (ARNI) may be substituted for ACE inhibitors or ARBs and Ivabradine may also be considered in subjects with a heart rate >70bpm. Stable is defined as no more than a 100% increase or 50% decrease in dose.
  • Subjects who, in the opinion of the Principal Investigator (based on the current guidelines for clinical practice), have a clinical indication for an implanted cardiac defibrillator (ICD, e.g., EF≤35%) and/or pacemaker, must have an existing device unless the patient refuses to undergo the implantation of such device for personal reasons.
  • Subjects who are willing and able to return for all follow-up visits.

Exclusion Criteria:

  • Subjects whose baseline peak VO2 is <9 or >20 ml O2/min/kg. The qualifying CPX test must be deemed adequate.
  • Subjects who have a potentially correctible cause of heart failure, such as valvular heart disease or congenital heart disease.
  • Subjects who have clinically significant angina pectoris, consisting of angina during daily life (i.e., Canadian Cardiovascular Society Angina score of II or more), an episode of unstable angina within 30 days before enrollment, or angina and/or ECG changes during exercise testing performed during baseline evaluation.
  • Subjects hospitalized for heart failure requiring acute treatment with intravenous loop diuretics, IV inotropes or hemofiltration within 30 days before enrollment and baseline testing or subjects receiving any form of positive inotropic support within 30 days before enrollment, including continuous IV inotrope therapy.
  • Subjects having a PR interval greater than 375ms.
  • Subjects whose exercise tolerance is limited by a condition other than heart failure (e.g., angina, COPD, peripheral vascular disease, orthopedic or rheumatologic conditions) or who are unable to perform baseline stress testing.
  • Subjects who are scheduled for a CABG or a PTCA procedure, or who have undergone a CABG procedure within 90 days or a PTCA procedure within 30 days of enrollment.
  • Subjects who have a biventricular pacing system, an accepted indication for such a device, or a QRS width of 130ms or greater.
  • Subjects who have had a myocardial infarction within 90 days of enrollment.
  • Subjects who have mechanical tricuspid valve.
  • Subjects who have a prior heart transplant.
  • Subjects on dialysis.
  • Subjects who are participating in another experimental protocol.
  • Subjects who are unable to provide informed consent.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Optimizer Smart System with 2-leads
All eligible subjects will have the Optimizer Smart System implanted and receive cardiac contractility modulation therapy (CCM).
Device: Optimizer Smart System with 2-leads
The Optimizer Smart System with 2-leads delivers non-excitatory cardiac contractility modulating (CCM) electrical signals to the heart muscle. Implanted subjects receive five non-contiguous one-hour periods of CCM signals per day.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in exercise tolerance quantified by peak VO2 measured on cardiopulmonary exercise stress testing (CPX).
Time Frame: 24 weeks
Device efficacy will be assessed as change in exercise tolerance quantified by peak VO2 measured on cardiopulmonary exercise stress testing (CPX). Subjects on device under FIX-HF-5C2 protocol will be compared to subjects on control under FIX-HF-5C protocol with respect to peak V02 mean change at 24-weeks from baseline.
24 weeks
Optimizer-device and -procedure related complication rate
Time Frame: 24 weeks
Subjects experiencing an Optimizer device- or procedure-related complication through the 24-week study period, as determined by an independent events committee.
24 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Total CCM delivery comparing 2 and 3-lead device configurations
Time Frame: 24 weeks
A comparison will be made between the Optimizer per-protocol groups in the FIX-HF-5C (3-lead) and FIX-HF-5C2 (2-lead) device configurations to show there is no difference between the amount of CCM therapy provided by the two device configurations. Total CCM delivery (effective hours delivered) will be evaluated at the end of 24 weeks following the Optimizer implantation.
24 weeks
