March 23, 2026 updated by: Impulse Dynamics

Broaden Accessibility of Breakthrough Treatment for Heart Failure: A Prospective, Propensity-Matched CED to Access the Impact of Cardiac Contractility Modulation Therapy (CCM)

The purpose of this prospective, multi-center, propensity-matched coverage with evidence development (CED) study is to assess the impact of cardiac contractility modulation (CCM) on mortality and heart failure hospitalizations in Medicare-eligible patients with heart failure who meet indications for CCM.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

Data for both the CCM treatment arm and a propensity-matched control group come from a large, de-identified, aggregated electronic health record (EHR) database containing patient information from multiple U.S. healthcare systems. The database includes demographics, clinical notes, imaging, laboratory results, medications, social determinants of health, and other relevant healthcare information, with up to 8 years of historical clinical data updated regularly.

Study Type

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Participants are patients with heart failure who are identified from a large, de-identified, multi-system electronic health record (EHR) database representing diverse healthcare settings across the United States. The database includes patients receiving care in hospitals, outpatient clinics, and other sites where cardiac contractility modulation (CCM) therapy is delivered. The population reflects typical sites of CCM implantation in Medicare-eligible adults across multiple states and integrated delivery networks (IDNs).

Description

Inclusion Criteria

  1. Continuous representation in the database in the year prior to index.
  2. Age 18 or older will be enrolled in either the treatment or control arm of the study.
  3. NYHA III heart failure,
  4. Not receiving CRT
  5. EF 25 - 45%, inclusive.
  6. Remain symptomatic despite at least 3 months of optimized guideline-directed medical therapy (GDMT) as determined by the heart team prior to CCM implantation.

Exclusion Criteria

  1. Subject has had a prior heart transplant
  2. Subject with mechanical tricuspid valve.
  3. Subject has a left ventricular assist device (LVAD).

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Treatment Group
Treatment patients shall be those with a clinical indication for CCM implantation according to FDA approved labeling and who are implanted with the Optimizer System.
Device: Cardiac Contractility Modulation (CCM)
CCM is a therapy delivered via the Optimizer System, which is implanted in eligible heart failure patients. The device delivers non-excitatory electrical signals to the heart during the absolute refractory period, enhancing the strength of cardiac contractions without increasing myocardial oxygen consumption.
Control Group
The control group shall be derived from propensity score matching of patients derived from the database with a clinical indication for CCM implantation who do not receive an implant.

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
Time to first heart failure hospitalization or all-cause death
Time Frame: Up to 2 years post-index date for each patient; follow-up will continue until 2 years after the last patient is enrolled to allow at least 2 years of observation for all participants.
Time from index date to the first occurrence of either heart failure-related hospitalization or death in patients with a clinical indication for cardiac contractility modulation (CCM) therapy. Outcomes will be compared between patients implanted with the Optimizer System (treatment arm) and a propensity score-matched control group of patients who are eligible for CCM but did not receive the device. Data will be collected from a large, de-identified, multi-system electronic health record database representing diverse sites of care across the United States.
Up to 2 years post-index date for each patient; follow-up will continue until 2 years after the last patient is enrolled to allow at least 2 years of observation for all participants.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to recurrent heart failure hospitalization
Time Frame: Up to 2 years post-index date for each patient; follow-up continues until 2 years after the last patient is enrolled to allow at least 2 years of observation.
Time from index date (CCM implantation for treatment patients) to each heart failure-related hospitalization, including first and subsequent hospitalizations, in patients receiving CCM therapy compared with a matched control group of patients eligible for CCM but not treated. This outcome is exploratory and hypothesis-generating.
Up to 2 years post-index date for each patient; follow-up continues until 2 years after the last patient is enrolled to allow at least 2 years of observation.
Time to all-cause mortality
Time Frame: Up to 2 years post-index date for each patient; follow-up continues until 2 years after the last patient is enrolled to allow at least 2 years of observation.
Time from index date (CCM implantation for treatment patients) to death from any cause, in patients receiving CCM therapy compared with a matched control group of patients eligible for CCM but not treated. This outcome is exploratory and hypothesis-generating.
Up to 2 years post-index date for each patient; follow-up continues until 2 years after the last patient is enrolled to allow at least 2 years of observation.
