Outcomes

Primary Outcome Measures

The proportion of participants with resolution of significant Sleep Disordered Breathing (SDB) symptoms as defined by the parent completed Brouillette questionnaire </=-1 at 6 weeks
The Brouillette questionnaire is a validated symptom questionnaire that investigates the presence of respiratory sleep disorders and the frequency of apnoea and pathological snoring. Each item is scored from 0 to 3 (0 = absence of symptoms, 1 = occasional symptoms, 2 = frequent symptoms, and 3 = constant symptoms), and the overall score is directly proportional to disease severity. The proportion of participants in each treatment arm with resolution of symptoms at 6 weeks will be calculated with 95% confidence intervals (CIs). The treatment arms will be compared using a Mantel Haenszel chi-squared test.

Secondary Outcome Measures

The proportion of participants with resolution of significant Sleep Disordered Breathing (SDB) symptoms as defined by the parent completed Brouillette questionnaire < -1 at 12 weeks
The Brouillette questionnaire is a validated symptom questionnaire that investigates the presence of respiratory sleep disorders and the frequency of apnoea and pathological snoring. Each item is scored from 0 to 3 (0 = absence of symptoms, 1 = occasional symptoms, 2 = frequent symptoms, and 3 = constant symptoms), and the overall score is directly proportional to disease severity. The proportion of participants in each treatment arm with resolution of symptoms at 12 weeks will be calculated with 95% confidence intervals (CIs). The treatment arms will be compared using a Mantel Haenszel chi-squared test.
An improvement of score in parent completed Pediatric Sleep Questionnaire-sleep disordered breathing subscale (PSQ-SDB subscale) at week 6 when compared with baseline measured at the start of the intervention period (week 0)
The Pediatric Sleep Questionnaire - sleep disordered breathing subscale is a validated questionnaire which contains 22 symptom items that ask about snoring frequency, loud snoring, observed apneas, difficulty breathing during sleep, daytime sleepiness, inattentive or hyperactive behaviour, and other paediatric Obstructive Sleep Apnoea (OSA) features. Responses are "yes" = 1, "no" = 0, and "don't know"=missing. The mean scores and 95% confidence intervals (CIs) in the two treatment arms will be calculated and the treatment arms will be compared using a linear regression adjusted for centre.

This questionnaire consists of 23 items evaluating physical, emotional, social and scholastic functioning, and it integrates both generic core scales and disease-specific modules. The mean scores and 95% confidence intervals (CIs) in the two treatment arms will be calculated and the treatment arms will be compared using a linear regression adjusted for centre.
An improvement of score in parent completed Strengths and Difficulties Questionnaire (SDQ) at week 6 when compared with baseline measured at the start of the intervention period (week 0).

Number of adverse events (AEs) throughout the treatment phase
Participants will also be asked questions about hospitalisation, accidents, new or changed medications. In addition AE's will be documented from physical examination findings, clinically significant lab results or other documents (including diaries where solicited AE's are prompted and correspondence from their primary care physician) that are relevant to participant safety. Adverse events and adverse reactions (non-serious or serious will be captured) The number of AEs will be summarised and listed in each of the treatment arms.
Number of adverse events (AEs) within the first week of the treatment
Participants will also be asked questions about hospitalisation, accidents, new or changed medications. In addition AE's will be documented from physical examination findings, clinically significant lab results or other documents (including diaries where solicited AE's are prompted and correspondence from their primary care physician) that are relevant to participant safety. Adverse events and adverse reactions (non-serious or serious will be captured) The number of AEs will be summarised and listed in each of the treatment arms.
Compliance of medical therapy measured by weight of sent and returned bottles of medication
Bottles will be weighed before they are given to participants and weighed when they are returned. The amount used will be calculated and used to determine if the participant was compliant with dosing. The amount of one spray of medication will be measured to allow for compliance to be calculated. Compliance with treatment will be calculated as the proportion of prescribed doses over 6 weeks that was consumed based on the weight of the bottles. The mean compliance will be summarised for the run-in period and both treatment arms. The proportion of participants with 80% and more compliance will be given for each treatment arm. The amount of one spray of medication will be measured to allow for compliance to be calculated.
Clinical factors at baseline that are associated with response to interventions, based on statistical analysis
Logistical regression models will be fitted to determine whether clinical factors at baseline or severity of SDB symptoms at baseline were associated with response to the intervention. Treatment arm, the symptom or factor of interest, and the interaction between the treatment arm and the symptom or factor will be included in this model. Symptoms or factors of interest include demographic factors, severity of SDB at baseline, history of atopy and history of tonsillitis.

5. Study Description

Brief Summary
MIST+ is studying a nasal spray to see if it will reduce the need for surgery for snoring. Children aged 3-12 are invited to take part. Snoring affects up to 10% of children and can cause sleeping problems and concentration or behavioural issues in the daytime. Currently the most common treatment for snoring is surgery to remove the tonsils and/or adenoids, however many children wait a long time to see a specialist. This research is trying to find if nasal sprays can help children with snoring, and whether this can reduce the need for surgery.
Detailed Description
MIST+ is a multi centre, double-blind, placebo controlled trial. Children 3-12 years of age, who do not respond to a run-in phase of 6 weeks of normal saline intranasal spray to treat sleep disordered breathing, will be randomised 1:1 to a treatment phase of either intranasal corticosteroid (investigational product) or normal saline (placebo). Participants will receive treatment for 6 weeks and receive followup at at 12 weeks, 6, 12, 18 and 24 months.

Description
The Pediatric Quality of Life Inventory (PedsQL) is a validated, standardised, generic assessment instrument that provides a modular approach to measure health related quality of life in healthy children and adolescents and those with acute and chronic disorders. This questionnaire consists of 23 items evaluating physical, emotional, social and scholastic functioning, and it integrates both generic core scales and disease-specific modules. The mean scores and 95% confidence intervals (CIs) in the two treatment arms will be calculated and the treatment arms will be compared using a linear regression adjusted for centre.
