Cognitive-Behavioral and Pharmacologic (LDX) Treatment of Binge-Eating Disorder and Obesity: Maintenance Treatment

This study will test the effectiveness of lisdexamfetamine (LDX) medication as a maintenance therapy for the treatment of binge-eating disorder (BED) in patients with obesity. This is a controlled test of whether, amongst responders to acute treatments, LDX medication results in superior maintenance and longer-term outcomes compared with placebo.

About this study

Obesity is a heterogeneous problem and research has highlighted the particular significance of a subgroup with binge-eating disorder (BED), the most prevalent formal eating disorder. Improved treatments for patients with obesity and BED are needed that can produce sustained clinical outcomes and promote weight loss. This study (maintenance stage) RCT will provide findings from a controlled test, amongst responders to acute treatments, whether LDX medication results in superior maintenance and longer-term outcomes than placebo. This is one of the few RCTs for BED of medication with follow-up after medication discontinuation.

Primary outcomes

  1. Binge-Eating Relapse

    Time frame: 12 weeks

    Relapse will be scored as a yes/no (categorical variable); this categorical variable will be based on frequency of binge-eating episodes assessed using the Eating Disorder Examination interview; Relapse category will be defined as ≥4 binge-eating episodes per month.

  2. Binge-Eating Relapse

    Time frame: 6-month follow-up

    Relapse will be scored as a yes/no (categorical variable); this categorical variable will be based on frequency of binge-eating episodes assessed using the Eating Disorder Examination interview; Relapse category will be defined as ≥4 binge-eating episodes per month.

  3. Binge-Eating Relapse

    Time frame: 12 month follow-up

    Relapse will be scored as a yes/no (categorical variable); this categorical variable will be based on frequency of binge-eating episodes assessed using the Eating Disorder Examination interview; Relapse category will be defined as ≥4 binge-eating episodes per month.

Secondary outcomes

  1. Change in Binge-Eating Frequency

    Time frame: From baseline interview at study enrollment to 3 months after the 12-week treatment

    Binge-eating frequency is a continuous variable of binge-eating episodes assessed using the Eating Disorder Examination interview; Binge-eating frequency will be based on the past 28 days and defined as binge-eating episodes per month.

  2. Change in Binge-Eating Frequency

    Time frame: From post-treatment to the 6-month follow-up

    Binge-eating frequency is a continuous variable of binge-eating episodes assessed using the Eating Disorder Examination interview; Binge-eating frequency will be based on the past 28 days and defined as binge-eating episodes per month.

  3. Change in Binge-Eating Frequency

    Time frame: From post-treatment to the 12-month follow-up

    Binge-eating frequency is a continuous variable of binge-eating episodes assessed using the Eating Disorder Examination interview; Binge-eating frequency will be based on the past 28 days and defined as binge-eating episodes per month.

  4. Change in Eating-Disorder Psychopathology (Continuous)

    Time frame: From baseline interview at study enrollment to 3 months after the 12-week treatment

    Eating-disorder psychopathology is a continuous variable as assessed by the global score of the Eating Disorder Examination/Eating Disorder Examination-Questionnaire. Scores range from 0-6 (0=no eating-disorder psychopathology; 6=severe eating-disorder psychopathology).

  5. Change in Eating-Disorder Psychopathology (Continuous)

    Time frame: From post-treatment to the 6-month follow-up

    Eating-disorder psychopathology is a continuous variable as assessed by the global score of the Eating Disorder Examination/Eating Disorder Examination-Questionnaire. Scores range from 0-6 (0=no eating-disorder psychopathology; 6=severe eating-disorder psychopathology).

  6. Change in Eating-Disorder Psychopathology (Continuous)

    Time frame: From post-treatment to the 12-month follow-up

    Eating-disorder psychopathology is a continuous variable as assessed by the global score of the Eating Disorder Examination/Eating Disorder Examination-Questionnaire. Scores range from 0-6 (0=no eating-disorder psychopathology; 6=severe eating-disorder psychopathology).

  7. Change in Depressive Symptoms

    Time frame: From baseline interview at study enrollment to 3 months after the 12-week treatment

    Depressive symptoms is a continuous variable of depressive symptomatology as assessed by the self-report measure, the Beck Depression Inventory - Second Edition. Scores range from 0-63 (0=no depressive symptoms, 63=greater depressive symptoms).

  8. Change in Depressive Symptoms
