Study Summary

The purpose of the study is to investigate the effect and safety of the Walther System delivering INMEST (intranasal mechanical stimulation) on people with Sjogren&#39;s syndrome. A total of 30 subjects are planned to be enrolled and randomized to either use an active device or a sham device for the first 6 weeks. During the last 6 weeks all subjects will receive active treatment. The treatments are self-administered by the subject at home, three times a week and 10 minutes per nostril.

Subjects will:

Use an active or sham device at home 3 times per week for six weeks.
All subjects will then get an active device for use another six weeks.
Visit the clinic every third week for measurements and checkups.
Keep a diary of the treatments and potential problems.

Study Description

Clinical investigation purpose and background ----- In this investigation the intended purpose of the investigational device, the Walther System, is to deliver intranasal mechanical stimulation (INMEST) for symptom relief in cases of Sjogren's syndrome, and the treatment is self-administered at home.

Sjogren&#39;s syndrome is a chronic disorder of the immune system that usually affects the mucous membranes and moisture-secreting glands of the eyes and mouth. The two most common symptoms of Sjogren's Syndrome are dry eyes and a dry mouth. The prevalence has been reported to be 0.06% and the disease mostly affect women and people over 40. There are currently no treatment options for Sjogren&#39;s syndrome other than relieving symptoms resulting in medications that decrease eye inflammation, increase saliva production, and/or suppress the immune system.

Design of clinical investigation

This is a randomized, double-blinded, single centre, pilot study with a total of 30 study subjects, from 18 years of both genders. Randomization of study subjects is done in permuted blocks and the subjects are randomized to either one of two groups of equal size receiving either:

A. treatment with the investigational device (active) B. treatment with comparator device (sham/control) After half the treatment time all subjects are given a new investigational device that is active, thus all subjects will receive active treatment.

After enrolment in the study, including the informed consent procedure, and the subsequent randomization process, study subjects are assigned to either an investigational device treatment (group A) or a comparator treatment group (group B). After an initial demonstration of the device (comparator or investigational device), study subjects will be given the device to be used for self-administration at home, 3 days a week, 10 minutes per nasal cavity (i.e. a total of 20 minutes per treatment session), for a total treatment period of 12 weeks (i.e., a total of 36 treatment sessions). After 6 weeks all subjects, irrespective of group, will exchange their device for an investigational device, thus all subjects will receive active treatment for the last 6 weeks.

Clinic visits with measurements are scheduled at baseline followed at visits after 3, 6, 9, and 12 weeks when end of treatment is reached. Every visit after baseline should be made within a time window of -3 days to +10 days. Subjects are instructed not to perform any treatments with the device 12 hours prior visiting the clinic.

During the study period, both patients' reported symptoms and objective measurements will be collected. An analysis will also be made of compliance with the prescribed treatment and the safety of the investigational medical device will be evaluated through analysis of reported adverse events and device deficiencies.
