NCT03063606

Brief Summary

This study will test the effectiveness of cognitive-behavioral therapy as a specialist treatment for binge eating disorder (BED) in patients with obesity. This is a controlled test of whether, amongst non-responders to acute treatments, cognitive-behavioral therapy augments on-going blinded pharmacotherapy (either naltrexone/bupropion or placebo), compared with no additional behavioral treatment .

Outcome Measures

Primary Outcomes (2)

  • Binge Eating Frequency (Continuous)

    Binge eating assessed by interview and reported as frequency in the past 28 days. Frequency is defined continuously.

    Post-treatment (4 months)

  • Change in Body Mass Index at 4 Months Post-Treatment From Baseline

    BMI is calculated using measured height and weight. We report percent of baseline weight. Negative values indicate weight loss. Calculated by value at 4 months minus value at baseline

    Baseline and Post-treatment (4 months)

Secondary Outcomes (2)

  • Binge Eating Frequency (Continuous)

    6-Month Follow-up

  • Binge Eating Frequency (Continuous)

    12-Month Follow-up

Other Outcomes (2)

  • Body Mass Index

Study Arms (2)

Cognitive-Behavioral Therapy (CBT)

EXPERIMENTAL

CBT is a "specialist" focal treatment with three overlapping phases. (1) Establishing a collaborative therapeutic relationship while focusing on educating patients about the nature of binge eating and factors thought to maintain the problem. Specific behavioral strategies (e.g., self-monitoring) are used to help patients identify problematic eating behaviors while establishing a normal structured eating pattern. (2) Integrating cognitive restructuring procedures, focusing on helping patients learn to identify and challenge maladaptive cognitions regarding eating and weight/shape and thoughts that trigger binge eating. (3) Maintaining change and preventing relapse.

Behavioral: Cognitive-Behavioral Therapy (CBT)Drug: NB Medication (on-going from acute treatment)

Naltrexone/bupropion (NB) (on-going from acute stage)

ACTIVE COMPARATOR

Participants will continue acute blinded pharmacotherapy (consisting of either naltrexone/bupropion combination or placebo), but without added cognitive-behavioral therapy.
