About this study

Official title: Long-term Evaluation of the Effectiveness Of a Novel Intra-oral Electro-stimulator for the Treatment of raDiotherapy-ASsociated Dry Mouth

This trial is looking at using an intra-oral electrostimulating device for the management of radiotherapy-induced dry mouth.

Read the detailed description

Dry mouth is a common complaint of radiotherapy for cancer of the head and neck region. It is a distressing often persistent condition which can lead to longlasting oral discomfort, dental infections, diminished quality of life, social isolation and loneliness. Unfortunately, current therapies of dry mouth are often unsatisfactory, expensive and may result in adverse effects. A novel intraoral electronic device has recently been developed to treat dry mouth. The device, acting as a "salivary pacemaker", harmlessly stimulates nerves of the salivary glands and does not cause adverse side effects. The aim of this proposal is to assess the longterm effects of such a device in this population, which have yet to be investigated, to demonstrate whether its daily application is an effective method of lessening dry mouth and improving life quality. 84 individuals will be enrolled in the study to use the device for 12 months, after receiving appropriate instructions. 42 participants (out of 84) will act as controls as they will receive a sham device that will not deliver electric stimuli but only tactile stimulation (like using a chewing gum). All participants will be allowed to continue using their routine local therapy for dry mouth (e.g. artificial saliva) during the study. Each participant will keep a diary relevant to the frequency of use and potential changes in dry mouth sensation. Participants will also be asked to attend hospital appointments to measure changes in saliva production and complete questionnaires on their dry mouth and quality of life. The device has the potential to radically change current clinical practice. If the trial is successful, the use of the device will provide patients having radiation-induced dry mouth with a safe and drug-free therapeutic modality.

What is being measured

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

  1. Improvement of subjective perception of dry mouth as measured on the Visual Analog Scale

    The primary outcome is defined as the proportion of patients reporting a 30% reduction of xerostomia symptoms as evaluated through a 100mm VAS (100mm=maximum dryness).

    Measured: 12 month

Secondary outcomes (5)
  1. Salivary function

    Improvement of objective salivary function as measured through 5-minutes sialometry

    Measured: 12 month

  2. Head and Neck cancer Quality of Life

    Improvement in head and neck quality of life as measured on the EORTC QLQ-H\&N35

    Measured: 12 month

  3. Oral Health Quality of Life

    Improvement in oral health quality of life as measured on the OH-QoL16 questionnaire

    Measured: 12 month

  4. General quality of Life

    Improvement in general quality of life as measured on the SF-36 questionnaire

    Measured: 12 month

  5. Participant compliance

    Evaluation of patients' tolerance in using the device by using a diary to record daily measurement.

    Measured: 12 month

Questions about this trial

What is this clinical trial studying?

A study testing Active Electrostimulator device in people with Xerostomia and Head and Neck Neoplasms, run by University College, London.

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 7 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: finished, as of the sponsor's last update on 3 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. 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.

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?

Improvement of subjective perception of dry mouth as measured on the Visual Analog Scale (time frame: 12 month). 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 3 Nov 2021.
