Design outcomes

Primary

MeasureTime frame
1. ADHD symptoms measured using Swanson, Nolan, and Pelham Rating Scale (SNAP-IV) at 12 weeks post-randomisation 2. Tics severity measured by Yale Global Tic Severity Scale (YGTSS) Total Tic Severity Score (TTSS) at 12 weeks post-randomisation

Secondary

MeasureTime frame
1. Clinical: 1.1 ADHD symptoms measured using SNAP-IV at 24 and 52 weeks 1.2 Tics severity measured by YGTSS (TTSS) at 24 and 52 weeks 1.3 Global measure of clinical functioning: Clinical Global Impressions (CGI-I) at 1–12, 24 and 52 weeks 2. Safety: 2.1 Medication adverse events at 1–12, 24 and 52 weeks. Adverse events will be recorded throughout the 52-week follow-up period on a modified version of the side effects scale developed by Hill and Taylor. Serious adverse events will be recorded and reported in a timely fashion (within 24 hours of awareness of the event) following the procedure outlined in the protocol submitted with this application. Cardiovascular examination (blood pressure and pulse) will be conducted as part of routine safety monitoring as required. Physical measures and monitoring will be adjusted depending on treatment route; a decision based on individual risk factors and the baseline examination. 3. Health Economics: 3.1 Child health-related quality of life: Child Health Utility – Nine Dimensions (CHU-9D), EQ-5DY at Baseline, 12, 24 and 52 weeks 3.2 Parent health-related quality of life: EQ5D-5I at Baseline, 12, 24 and 52 weeks
