About this study

Official title: Clinical Evaluation of the Therapeutic Intra-Vascular Ultrasound (TIVUS™) System for Pulmonary Artery Denervation (PDN) in Patients With Pulmonary Hypertension

The objective of this study is to assess the safety, performance and initial effectiveness of the TIVUS™ System when used for pulmonary artery denervation through subjective and objective change in clinical parameters and haemodynamic evaluation. This is a prospective, multi-center, non-randomized, open-label clinical trail. The study will be conducted in up to 5 centers and will recruit up to 15 patients diagnosed with PAH, functional class III who have stable PAH on a stable drug regimen of two pulmonary arterial hypertension specific medications.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Therapeutic Intra-Vascular UltraSound (TIVUS™) SystemDevice

    The TIVUS™ System generates high intensity, non-focused ultrasonic energy that is delivered through the wall of the pulmonary artery to achieve local nerve deactivation.

    Denervation in the pulmonary arteries (PDN) would be performed during right heart catheterization. The PDN procedure would be attempted in the main, right and left pulmonary arteries, close to the main bifurcation.

Study groups in NCT02516722
Study groupRoleWhat they receive
Pulmonary DenervationExperimentalPulmonary Denervation (PDN) using the TIVUS™ System will be performed in patient suffering from pulmonary arterial hypertension after completion of screening and eligibility phase, The procedure will be performed during right heart catheterisation. Safety and effectiveness of the PDN treatment will be assessed during one year follow up.
Receives: Device: Therapeutic Intra-Vascular UltraSound (TIVUS™) System

Questions about this trial

What is this clinical trial studying?

A study testing Therapeutic Intra-Vascular UltraSound (TIVUS™) System in people with Pulmonary Arterial Hypertension, run by SoniVie Inc. at 4 sites in 3 countries.

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 6 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 16 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United Kingdom, Belgium, Israel. 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?

Results are not available in the source record.

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?

Safety evaluation of the PDN procedure (Procedural related Adverse Events) (time frame: 1 month). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Mar 2021.
