About this study

Official title: Safety and Performance Evaluation of an Electro-stimulator Mounted on an Intra-oral Removable Appliance (Saliwell GenNarino) for the Treatment of Xerostomia

This is a multinational trial, aimed at testing the safety and performance of a electrostimulating device ("GenNarino") to treat dry mouth, over one year. The design is as follows:

  • Multi-center, double blind, sham (placebo) controlled, about 10 xerostomia patients per center
  • Patients receive a GenNarino (and its remote control) that is programmed for one month sham and one month active mode (the order of which is randomly assigned), and thereafter 9 months at the active mode (divided in period of 3 months, the order of each is randomly assigned at wearing GenNarino for 1, 5 or 10 minutes at a time).

Study hypothesis: Gennarino will lead to significant symptomatic improvement

  • At the clinic: monthly examinations at the first 2 months, and then every 3 months, including whole saliva collection and questionnaire; at the first visit impression taking for GenNarino preparation
Read the detailed description

The clinical trial, titled "Safety and performance evaluation of an electro-stimulator mounted on an intra-oral removable appliance (GenNarino) for the treatment of xerostomia" is a prospective, randomized, double-blind, sham-controlled multi-center trial, followed by an open-label study. Study subjects are patients with xerostomia. The purpose of the trial is to test the safety and efficacy of electrostimulation using the GenNarino device.

The primary endpoint is significant symptomatic improvement, and the secondary ones, increased salivary output and event free use (no adverse side-effects). The clinical follow-up consists of periodic clinical examinations.

In this clinical trial the use of the device is compared between active vs. sham mode for one month each in a double-blind design (Stage I). Thereafter, at Stage II the xerostomia relieving effect of the active device is assessed in an open label design for additional 6 months. Clinic- and home-based questionnaires and whole saliva collections are performed.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Electrostimulation in people with Xerostomia, run by Saliwell Ltd. at 1 site in Finland.

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 10 inclusion and 13 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 6 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Finland. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Significant symptomatic improvement (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00509808, which also lists 1 linked publication.

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 6 Apr 2010.
