About this study

Official title: Safety and Efficacy of Cryoablation in Management of Sialorrhea in Patients With Neurological Disorders.

To evaluate safety of cryoablation of submandibular glands in management of sialorrhea in neurologically impaired populations.

What participants receive

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

  • CRYOABLATIONDevice

    Also called SeedNet® System

    The SeedNet® System induces freezing and thawing at the tip of the needle. These freezing and thawing processes are based on the Joule-Thomson effect. The unique technology of the SeedNet® System provides extremely rapid freeze and thaw operations. The system's software controls the flow of gases from the gas sources, through the manifold, to the needle and probe tips. The system can immediately switch from the freezing process to the thawing process, after which the needle can be released. This device is an FDA-cleared medical device. This IDE application is to allow for use of the commercially available device in a new clinical indication, namely cryoablation of the submandibular glands.

What is being measured

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

  1. To evaluate safety of cryoablation of submandibular glands in management of sialorrhea in neurologically impaired populations.

    1. Safety Parameters: Major adverse events will be submitted to the Agency and be reviewed by the medical monitor. In case unexpected events should occur we will evaluate and report them.

    2 Methods for Analyzing Safety Parameters: Prior to the enrollment of the first research subject, the study sponsor will organize and conduct an initial meeting for the medical monitor. The medical monitor will review AE logs, deviation logs, procedural details, call logs, phone scripts, study progress notes, patient medical charts, and completed questionnaires, every 5 patients, or quarterly, whichever takes place first. The sponsor-investigator will oversee the conduct of the medical monitor. Directives provided by the medical monitor will be reported accordingly and as necessary to the Food and Drug Administration and the IRB.

    Measured: 2 years

Secondary outcomes (1)
  1. To evaluate efficacy of cryoablation of submandibular glands in management of sialorrhea in neurologically impaired populations.

    1. Efficacy Parameters: Efficacy is defined as reduced score on the Drooling Impact Scale (range: 10-100) at baseline, 1 and 6 months interval with-in subject self-assessment.
    2. Methods for Analyzing Efficacy Parameters:

    We will qualitatively assess the impact of drooling on patients, their families, and/or caretakers, at baseline, then twice post procedurally, using a questionnaire. The questionnaire known as the Drooling Impact Scale 'DIS' has been devised to evaluate longitudinal changes in children with neurological disorders, and quantify short- to medium-term treatment benefits of saliva-control interventions.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A study testing CRYOABLATION in people with Sialorrhea and Neurologic Disorder, run by Dean Nakamoto.

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 5 inclusion and 7 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: withdrawn, as of the sponsor's last update on 29 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

To evaluate safety of cryoablation of submandibular glands in management of sialorrhea in neurologically impaired populations. (time frame: 2 years). 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 29 Nov 2021.
