Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of weeks after randomisation until a patient achieves a clinical relevant improvement* in core symptoms for the first time will be measured using a weekly symptom monitoring that includes questions about the number of binge eating and compensatory behaviours (vomiting, fasting, excessive exercise, use of laxatives, diuretics or appetite suppressants) and the current body weight of the participant. *Clinically relevant improvement is defined as abstinence from binge eating and compensatory behaviours (vomiting, fasting, excessive exercise, use of laxatives, diuretics or appetite suppressants) and a BMI of over 18.5, over a period of at least four weeks. Weekly symptom monitoring continues until 12 months post randomisation. | — |
