Study type
Description of intervention(s) / exposure
Arm 1: Neurostimulation device (EMS 2000) - Lacrimal gland neurostimulation. The current provided is approximately 1 milliamp with the patient controlling the amplitude with a knob. The recommended duration of treatment is approximately 30 seconds and the recommended treatment frequency is four times per day or as needed. The duration of the intervention period is 3 months.

Adherence to the intervention will be monitored by questioning of participants by study staff with responses recorded on case report forms.

Arm 2: Sham (non-functional) device

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by telephone/fax/computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s

Intervention assignment
Other design features
Phase 2
Type of endpoint(s)
Statistical methods / analysis
Because this is a Phase 2 clinical study, no formal hypothesis testing will be performed. Baseline and demographic characteristics will be presented. Continuous variables will be summarized by descriptive statistics (sample size; mean; standard deviation; median; minimum and maximum). Discrete variables will be summarized by frequencies and percentages. Adverse events will be summarized by presenting the number and percentage of participants having any adverse event. Any other information collected (such as severity or relationship to study device) will be listed as appropriate. Any statistical tests performed to explore the data will be used only to highlight any interesting comparisons that may warrant further consideration.
