Vyvanse® (lisdexamfetamine dimesylate) Capsules (CII) Becomes First and Only Treatment Approved by the FDA for Adults with Moderate to Severe Binge Eating Disorder

"Binge eating disorder is the most common adult eating disorder in the United States, and we are excited to provide the first FDA-approved treatment for moderate to severe B.E.D. in adults," said Philip J. Vickers, Ph.D., Global Head of Research and Development at Shire. "This new indication for Vyvanse is a critical milestone in the treatment of this condition and reflects our ongoing commitment to address the needs of patients."

"The management of B.E.D. is continuously being studied, and though advancements have been made to increase awareness and understanding of this real disorder, rates of diagnosis remain low," said Susan L. McElroy, M.D., Professor of Psychiatry and Behavioral Neuroscience, University of Cincinnati College of Medicine; and principal investigator of the B.E.D. clinical trials. "The development of new treatment options for adults with B.E.D. is important to the patients who continue to live with this complex disorder."  

The efficacy of Vyvanse in the treatment of B.E.D. was demonstrated in two 12-week randomized, double-blind, multi-center, parallel-group, placebo-controlled, dose-optimization studies in adults aged 18 to 55 years (Study 1: N=374, Study 2: N=350) with protocol-defined moderate to severe B.E.D. (severity was defined as having at least 3 binge days per week for 2 weeks prior to the baseline visit and a Clinical Global Impression Severity score of ≥4 at baseline). The primary efficacy outcome for the two studies was defined as the change from baseline at week 12 in the number of binge days per week. Baseline is defined as the weekly average of the number of binge days per week for the 14 days prior to the baseline visit.

Subjects from both studies on Vyvanse had a statistically significant greater reduction from baseline in mean number of binge days per week at Week 12. In study 1, Vyvanse reduced the mean number of binge days per week from 4.79 at baseline to 0.78 at study endpoint compared with 4.60 to 2.22 for placebo. The least squares mean change from baseline in binge days per week was -3.87 and -2.51 for Vyvanse and placebo, respectively.  Similar results were seen in study 2.

Vyvanse is a federally controlled substance (CII) because it can be abused or lead to dependence. Keep in a safe place to prevent misuse and abuse. Selling or sharing Vyvanse may harm others and is illegal. 

Greater improvement across key secondary outcomes was also observed in subjects treated with Vyvanse as compared to placebo, including a higher proportion of subjects rated improved on the Clinical Global Impressions-Improvement (CGI-I) rating scale, higher proportion of subjects with 4-week binge cessation, and greater reduction in the Yale-Brown Obsessive Compulsive Scale Modified for Binge Eating (Y-BOCS-BE) total score in both studies.

Patients with current anorexia or bulimia nervosa; current comorbid psychiatric disorder; and cardiovascular risk factors other than obesity and smoking were excluded from the studies. In both studies, there were 4 patients each in the Vyvanse and placebo treated groups who reported serious adverse events (SAEs). There were no deaths in either of the studies. Of patients treated with Vyvanse, 5.1% (19/373) discontinued due to adverse reactions compared with 2.4% (9/372) of placebo-treated patients. The most common adverse reactions (incidence ≥ 5% and at least twice placebo) reported in adults with moderate to severe B.E.D. were dry mouth, insomnia, decreased appetite, increased heart rate, constipation, feeling jittery, and anxiety.

About B.E.D. 

Binge eating disorder, now recognized as a distinct disorder, is defined as recurring episodes (≥ once weekly, for at least 3 months) of consuming a large amount of food in a short time, compared with others.  Patients feel a lack of control during a binge eating episode and marked distress over their eating.  They typically experience shame and guilt, among other symptoms, about their binge eating, and may conceal the symptoms. Unlike people with other eating disorders, adults with B.E.D. don't routinely try to "undo" their excessive eating with extreme actions like purging or over-exercising.

B.E.D. is the most common eating disorder in the United States, affecting an estimated 2.8 million adults, according to a national survey. B.E.D. occurs in both men and women, and is more common than anorexia and bulimia combined. B.E.D. can occur in normal weight,

overweight, and obese adults, and is seen across racial and ethnic groups. Medication is not appropriate for all adults with B.E.D.

More About Vyvanse (lisdexamfetamine dimesylate) B.E.D. Clinical Trials 

In the two 12-week studies, patients were confirmed with a diagnosis of B.E.D. using DSM-IV-TR^® criteria for B.E.D. For both studies, a binge day was defined as a day with at least 1 binge episode, as determined from the subject's daily binge diary and confirmed by the clinician.
