About this study

The goal of this study is to validate design for the Resolve™ Stimulator and Proximity Electrode and the associated procedure to quickly and safely place an electrode into the neck, in the vicinity of the vagus nerve by a physician in either the Emergency Department or other appropriate hospital inpatient setting (e.g., ICU). The secondary goal is to confirm that the electrical signal being delivered via this electrode rapidly counters bronchoconstriction and improves airway flow.

Read the detailed description

The present study is to evaluate the safety of a new neurostimulator device, the Resolve Stimulator and Proximity Lead™, which comprises an external electrical signal generator coupled to temporary electrode that is percutaneously inserted in the neck.

Sponsor believes, based on animal testing data provided as well as consultations with physicians who regularly treat patients suffering from attacks of acute bronchoconstriction in ER and inpatient hospital settings, that this device could be used in the skilled care hospital setting to help rapidly relax the smooth muscle in the airway, relieving a clinically significant portion of the bronchoconstriction suffered by patients experiencing moderate to severe asthma attacks, allowing more effective delivery of inhaled medications to restore the patient to his or her baseline respiration status.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety- Number of Participants With Adverse Events

    Safety- Number of participants that reported Adverse Events

    Measured: 2 weeks

Secondary outcomes (1)
  1. Improvement of Common Measures of Breathing Performance, Forced Expiry Volume in 1second (FEV1).

    An assessment of Forced Expiry Volume in 1second (FEV1) measurements were taken throughout the course of treatment (15,30 and 60 minutes).

    Peak FEV1 measurements were recorded for each subject, and the number of minutes the subject had received treatment at the time of peak FEV1.

    The threshold for improvement was set at 12% over baseline at any of the time points (15,30 and 60 minutes). Outcome measure data indicates the number of subjects above 12%.

    Measured: 60 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Resolve Stimulator and Proximity Lead in people with Asthma, run by ElectroCore INC at 6 sites in United States.

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 4 inclusion and 14 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 15 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. 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?

Yes. Results are posted in the registry (first posted 15 May 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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- Number of Participants With Adverse Events (time frame: 2 weeks). 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 15 May 2018.
