Study summary

The purpose of this registry (NCT02880631) is to evaluate the effect of BAROSTIM THERAPY with the BAROSTIM NEO System in the commercial setting in subjects recently implanted under the CE-Marked indication for resistant hypertension.

Read the detailed description

Summary:

The CVRx BAROSTIM THERAPY in Resistant Hypertension Registry will be performed with subjects who have been recently implanted with the BAROSTIM NEO System in accordance with CE-Mark approved criteria for resistant hypertension. Subjects must be enrolled within 30 days from implant. Up to 500 subjects will be enrolled at up to 50 sites. Data should be obtained from standard of care measurements taken prior to implant, at enrollment/baseline, and at 3, 6, and 12 months after the device was implanted. After 12 months, data may be obtained in six month intervals for up to three years after implant, at which time each subject will be exited from the registry.

Eligibility:

Subjects must sign an Ethics Committee (EC) approved informed consent form for the registry to participate.

Subjects can be included in the Hypertension Registry if they were implanted in the past 30 days and meet the CE-Mark approved indications and contraindications for the BAROSTIM NEO System in the treatment of resistant hypertension. These include:

  • Indications

    • Systolic blood pressure greater than or equal to 140 mmHg, and
    • Resistance to maximally tolerated therapy with a diuretic and two other anti-hypertension medications
  • Contraindications

    • Bilateral carotid bifurcations located above the level of the mandible
    • Baroreflex failure or autonomic neuropathy
    • Uncontrolled, symptomatic cardiac bradyarrhythmias
    • Carotid atherosclerosis that is determined by ultrasound or angiographic evaluation to be greater than 50%
    • Ulcerative plaques in the carotid artery as determined by ultrasound or angiographic evaluation

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Blood Pressure Changes

    The results of an office cuff blood pressure measurement to be obtained from a time point prior to implant and as close to the implant procedure as possible (baseline), at 3- and 6- and 12-months post-implant, and then every 6 months up to 3 years from implant.

    Time frame: Pre-implant baseline to 3 years post-implant

  2. Cardiovascular Medication Changes

    Information on currently-utilized doses of cardiovascular medications will be collected at pre-implant baseline, 3- and 6- and 12-months post-implant, and then every 6 months up to 3 years from implant.

    Time frame: Post-implant enrollment to 3 years post-implant

  3. Number of Health Care Utilizations

    Health care utilization information (e.g. heart failure hospitalizations) is collected at 3- and 6- and 12-months post-implant, and then every 6 months up to 3 years from implant.

    Time frame: 3 months post-implant to 3 years post-implant

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2016 (actual). Primary completion is estimated for Jul 2027, 127 months after the start.

Of 81 industry-sponsored observational studies under Hypertension, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 45. This study's planned 127 months is above that.

Counting every sponsor, half of 426 studies reached it within 38 months; a quarter within 17 and three quarters within 96.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
