Vyvanse® (Lisdexamfetamine Dimesylate) Capsules (CII) Becomes First And Only Treatment Approved By The FDA For Adults With Moderate To Severe Binge Eating Disorder

January 30, 2015

Shire plc (LSE: SHP, NASDAQ: SHPG) announced today that the U.S. Food and Drug Administration (FDA) approved Vyvanse® (lisdexamfetamine dimesylate) Capsules (CII), the first and only medication for the treatment of moderate to severe binge eating disorder (B.E.D.) in adults, shown to significantly reduce the mean number of binge days per week. Vyvanse is not indicated or recommended for weight loss or the treatment of obesity. Other sympathomimetic drugs used for weight loss have been associated with serious cardiovascular reactions.

“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.

  • the failure to obtain and maintain reimbursement, or an adequate level of reimbursement, by third-party payors in a timely manner for Shire’s products may impact future revenues, financial condition and results of operations;
  • Shire conducts its own manufacturing operations for certain of its products and is reliant on third party contract manufacturers to manufacture other products and to provide goods and services. Some of Shire’s products or ingredients are only available from a single approved source for manufacture. Any disruption to the supply chain for any of Shire’s products may result in Shire being unable to continue marketing or developing a product or may result in Shire being unable to do so on a commercially viable basis for some period of time;
  • the development, approval and manufacturing of Shire’s products is subject to extensive oversight by various regulatory agencies. Submission of an application for regulatory approval of any of our product candidates, such as our planned submission of a New Drug Application to the FDA for Lifitegrast, may be delayed for any number of reasons and, once submitted, may be subjected to lengthy review and ultimately rejected. Moreover, regulatory approvals or interventions associated with changes to manufacturing sites, ingredients or manufacturing processes could lead to significant delays, increase in operating costs, lost product sales, an interruption of research activities or the delay of new product launches;
  • the actions of certain customers could affect Shire’s ability to sell or market products profitably. Fluctuations in buying or distribution patterns by such customers can adversely impact Shire’s revenues, financial condition or results of operations;
