Registration Number

Lead Sponsor
CVRx, Inc.
Brief Summary

The purpose of this clinical trial (NCT02627196) is to develop valid scientific evidence for safety and effectiveness of Baroreflex Activation Therapy with the BAROSTIM NEO System in subjects with heart failure, defined as New York Heart Association (NYHA) functional Class III, left ventricular ejection fraction (LVEF) ≤ 35% and NT-proBNP\<1600 pg/ml despite being treated with the appropriate heart failure guideline directed therapy, excluding subjects eligible for or actively receiving Cardiac Resynchronization Therapy (CRT).

The total trial duration is anticipated to be approximately 5 years; however, the duration of an individual subject enrollment will depend on when he or she entered the trial.

Detailed Description

The BAROSTIM NEO - Baroreflex Activation Therapy for Heart Failure is a prospective, randomized trial in subjects with reduced ejection fraction heart failure. Subjects will be randomized in a 1:1 ratio to receive Barostim Activation Therapy with an implanted BAROSTIM NEO System in addition to medical management or to receive medical management alone (no device implant). The trial will be conducted at up to 120 investigational centers in the U.S. and up to 20 investigational centers outside the U.S. These centers will enroll up to 1200 subjects to randomize approximately 480 subjects who meet the entry criteria.

For all subjects, trial visits will occur at 0.5, 1, 1.5, 2, 3, 6, 9 and 12 months post-implant (post anticipated implant for medical management). Visits will occur quarterly from 15 to 24 months and semi-annually thereafter.

Subjects are followed in an identical manner regardless of trial arm.

The data will provide evidence of the safety and efficacy of BAROSTIM THERAPY. The accumulated morbidity and mortality data collected will provide evidence of morbidity and mortality benefit. This trial will involve one or more interim analyses to evaluate when sufficient evidence is reached for the final morbidity and mortality analysis.

  8. If female and of childbearing potential, must use a medically accepted method of birth control (e.g., barrier method with spermicide, oral contraceptive, or abstinence) and agree to continue use of this method for the duration of the trial. Women of childbearing potential must have a negative pregnancy test within 14 days prior to randomization.

  9. Received a standard cardiac work up and is an appropriate candidate for the study and the surgical procedure as determined by a trial cardiologist and a trial surgeon.

  10. Subjects implanted with a cardiac rhythm management device that does not utilize an intracardiac lead, or implanted with a neurostimulation device, must be approved by the CVRx Clinical department.

  11. Signed a CVRx-approved informed consent form for participation in this trial.

Exclusion Criteria

If any of the following criteria are met, subjects are not eligible for this trial.

  1. Received cardiac resynchronization therapy (CRT) within six months of randomization, or is actively receiving CRT.

  2. Currently have a Class I indication for a cardiac resynchronization therapy (CRT) device according to AHA/ACC/ESC guidelines for the treatment of congestive heart failure. ,

  3. Known or suspected baroreflex failure or autonomic neuropathy.

  4. AHA/ACC Stage D heart failure within 45 days prior to randomization.

  5. Body mass index > 40.

  6. Serum estimated glomerular filtration rate (eGFR) < 25 mL/min/1.73 m2 within 45 days prior to randomization.

  7. Recurring resting heart rate of either < 60 bpm or > 100 bpm via clinic measurements within 45 days prior to randomization. (Note: Heart rate <60 bpm is not applicable to subjects with an implanted device capable of pacing.)

  9. Significant uncontrolled symptomatic bradyarrhythmias or unstable ventricular arrhythmias.

  10. Subjects with any surgery that has occurred, or is planned to occur, within 45 days of the BAROSTIM NEO implant procedure. This includes pacemaker or ICD implants or battery replacements.
