Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of flares over 12 months. Flare is defined as the worsening of symptoms requiring increased application of TCS, measured via text/app/email reminders every 2 weeks for 12 months. | — |
Secondary
| Measure | Time frame |
|---|---|
| Clinical effectiveness: 1. Progression of scarring, assessed by a blinded assessor at 12 and 24 months by comparing the post-randomisation assessment to baseline photographs (if patients consented), or assessed clinically if consent has not been given for photographs: 1.1. Adults: scarring worsened (yes/no). 1.2. Children and adolescents: failure of normal vulval development (clinical assessment) and/or evidence of scarring (yes/no) 2. Vulval Architectural Severity Scale (VASS) at 12 and 24 months post-randomisation, assessed clinically 3. Time to first flare, measured via text/app/email reminders at the point of first flare 4. Clinician global severity assessment of LS using a 5-point ordinal scale at 3, 6, 12, 18 and 24 months. Also assessed by a blinded assessor at 12 and 24 months. This will be measured via clinical assessment. 5. Condition-specific quality of life (QoL) measured at 3, 6, 12, 18 and 24 months using: 5.1. Vulvar Quality Life Index (VQLI) (adults) 5.2. Children’s Dermatology Life Quality Index (CDLQI) (adolescents and children) 5.3. Sexual function (adults only) assessed using the Female Sexual Function Index at 12 and 24 months Safety: 1. Adverse reactions (e.g. stinging, skin thinning) measured throughout the trial by patient-reported symptoms and clinical examination from randomisation over 24 months 2. Development of vulval intraepithelial neoplasia or vulval squamous cell carcinoma at 24 months, measured by clinical assessment and/or medical notes Treatment acceptability and potential barriers/facilitators to treatment: 1. Acceptability of treatment strategy measured using a Likert scale at 12 and 24 months 2. Adherence to treatment measured using a bespoke questionnaire completed by participants at 3, 6, 12, 18 and 24 months 3. Qualitative interview sub-study at 12 months Cost-effectiveness: 1. Generic utility instrument to measure QoL at 3, 6, 12, 18 and 24 months with EQ-5D-5L (adolescents and adults) and Child Health Utility Instrumen | — |
