NCT02702167

Brief Summary

This trial will compare the efficacy and tolerability of 10 Hz vs. 1 Hz vs. sham repetitive transcranial magnetic stimulation targeting the dorsomedial prefrontal cortex, delivered once daily over 30 days, in patients with a diagnosis of bulimia or anorexia nervosa binge-purge subtype. The trial will include structural and functional MRI, and behavioral measures obtained before, during, and after treatment.

Outcome Measures

Primary Outcomes (1)

  • Weekly Binge/Purge Frequency on Eating Disorder Examination (EDE)

    Outcome measured by a change in weekly binge and purge episodes from baseline to 2 weeks post-treatment. A 50% improvement in the score is considered a response to rTMS. A final score of 0 weekly binges and 0 weekly vomits is categorized as remission.

    Baseline, after each week of treatment, and 1, 4, 12, and 24 weeks post-treatment

Secondary Outcomes (2)

  • Eating Disorder Inventory-3

    Baseline, after each week of treatment, and 1, 4, 12, and 24 weeks post-treatment

  • Eating Disorder Examination Questionnaire (EDE-Q)

    Baseline, after each week of treatment, and 1, 4, 12, and 24 weeks post-treatment

Other Outcomes (1)

  • Resting-state functional MRI

    1 week pre- and 1 week post-intervention

  • Outpatient
  • Between the ages of 18-65
  • Have had no increase or initiation of any psychotropic medication in the last 4 weeks prior to screening
  • Must adhere to research schedule.
