About this study
Official title: BackBeat Medical Cardiac Neuromodulation Therapy in Patients With Heart Failure: An Acute Feasibility Study
This investigation will evaluate the ability of the Moderato® System to safely and effectively deliver CNT, to reduce sympathetic activity in heart failure patients
Read the detailed description
This will be a single center, non-randomized observational study. The Moderato® System is approved for marketing in Europe (has a CE mark) for the treatment of high blood pressure in patients requiring standard cardiac pacing. The therapy delivered by the Moderato® System is referred to as CNT (Cardiac Neuromodulation Therapy). Heart failure patients is a population for which the Moderato® device is currently not indicated.
Subjects requiring an implantable cardiac defibrillator (ICD) implantation or replacement and meeting study inclusion and exclusion criteria will be eligible to participate in the study. The study procedure will take place during the ICD implantation (or replacement).
The whole procedure will be performed according to standard of care for ICD implantations (or replacements) including periprocedural prophylactic antibiotics prophylactic. To reduce the time of wound exposure, the setup of system for invasive measurements will be done before the ICD implant (or replacement) procedure begins.
The groin area will be prepared and draped. After applying local anesthesia, a 7Fr sheath will be inserted into the femoral artery. A small dose of heparin (~5000 units) will be administered intravenously to prevent formation of blood clots. Under fluoroscopic guidance, a standard conductance catheter (CD Leycom CA-71103-PL, CE marked) will be advanced into the left ventricle.
The arterial line will be used to measure arterial pressure. This completes the measuring system setup.
Then, ICD right atrial lead and right ventricular lead will be implanted in standard positions according to standard institutional practices.
The leads will be connected to a BackBeat Moderato® System IPG, externally to the patient using a single use, sterile Pacing System Analyzer (PSA) cable provided by the hospital. The Moderato® IPG, approved for chronic CNT delivery in hypertensive patients, will function in this trial as a temporary external CNT signal generator for acute application of the therapy.
A range of CNT signal parameters will be used to assess the effect on sympathetic activity. Ventricular pressure and volume readings from the conductance catheter and arterial pressure readings will be recorded and analyzed to assess the effect of CNT signals on cardiac function, sympathetic activity and blood pressure. The effects of CNT signal over a range of parameter settings will be studied over a period of time no longer than one hour.
In this study, none of the Moderato® system components will be in contact with the patient. The Moderato® IPG will be used solely as an external CNT signal generator and deliver signals to the patient through the PSA cable and the ICD leads.
When CNT signal activation is complete, data recording will be stopped, the conductance catheter will be removed, the cable connecting the IPG to the leads disconnected, and ICD implantation will proceed normally.
- Being tested
- CNT-HF
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CNT-HFDevice
A modified CNT, will be delivered as a pacing sequence able to acutely influence sympathetic tone.
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Arterial Elastance
Arterial elastance is reduced when sympathetic activity is reduced, an indication of a relaxed peripheral resistance.
Measured: Immediate, derived form ongoing Pressure Volume changes in the Left ventricle

Questions about this trial
What is this clinical trial studying?
An observational study of Heart Failure NYHA Class II and Heart Failure NYHA Class III, run by BackBeat Medical Inc at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Arterial Elastance (time frame: Immediate, derived form ongoing Pressure Volume changes in the Left ventricle). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04573699, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2026.
