Shire Announces FDA Acceptance For Filing With Priority Review Of Supplemental New Drug Application (Snda) For Vyvanse® (Lisdexamfetamine Dimesylate) Capsules (CII) For Adults With Binge Eating Disorder

Shire plc (LSE: SHP, NASDAQ: SHPG), the global specialty biopharmaceutical company, announced today that the US Food and Drug Administration (FDA) has accepted for filing with priority review a supplemental New Drug Application (sNDA) for Vyvanse^® (lisdexamfetamine dimesylate) Capsules (CII) as a treatment for adults with binge eating disorder (BED). The FDA is expected to provide a decision in February 2015, based on the anticipated Prescription Drug User Fee Act (PDUFA) action date.

“The decision from the FDA to accept our filing for priority review not only marks progress in the development of Vyvanse for adults with BED, but underscores this is an area of unmet medical need as there are currently no approved pharmacologic options for these patients,” said Phil Vickers, PhD, Head of Research and Development, Shire.

Vyvanse is a prescription medicine currently only approved for Attention-Deficit/Hyperactivity Disorder (ADHD). Vyvanse should only be used to treat ADHD.

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.

Shire is seeking approval for Vyvanse as a treatment option for adults with BED based on the results of two identically designed randomized placebo-controlled Phase 3 studies evaluating the efficacy and safety of Vyvanse versus placebo, previously announced in a press release dated November 5, 2013.¹

About BED

BED is a distinct eating disorder now recognized in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5^®).² BED is characterized by recurring episodes of eating significantly larger amounts of food in a discrete period of time (eg, any two-hour period) than most people would eat in a similar period of time under similar circumstances.² These episodes are associated with feelings of distress and lack of control (eg, the sense one cannot stop eating or control what or how much one is eating).

As described in DSM-5, a person with BED may eat much more rapidly than normal, eat until feeling uncomfortably full, eat large amounts of food when not feeling physically hungry, eat alone to hide the behavior due to embarrassment, or experience feelings of disgust, depression or guilt after a binge episode.² In these individuals, binge eating occurs, on average, at least once a week for three months.² Unlike bulimia nervosa and anorexia nervosa, BED is not associated with the recurrent use of inappropriate behaviors to compensate for binge eating (eg, purging, excessive exercise or fasting).²

About VYVANSE (lisdexamfetamine dimesylate)

Vyvanse is a prescription medicine currently only approved in the United States, Canada, Australia, several European countries (trade name: Elvanse^®/Tyvense^®) and Brazil (trade name: Venvanse™) for ADHD. Vyvanse should only be used to treat ADHD. Vyvanse should only be used in accordance with locally approved prescribing information.

INDICATION

Vyvanse is a prescription medicine for the treatment of ADHD in patients 6 years and above.

THE “SAFE HARBOR” STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

Statements included herein that are not historical facts are forward-looking statements. Such forward-looking statements involve a number of risks and uncertainties and are subject to change at any time. In the event such risks or uncertainties materialize, Shire’s results could be materially adversely affected. The risks and uncertainties include, but are not limited to, that:

and other risks and uncertainties detailed from time to time in Shire’s filings with the Securities and Exchange Commission, including those risks outlined in “Item 1A: Risk Factors” in Shire’s Annual Report on Form 10-K for the year ended December 31, 2013.
Shire’s products may not be a commercial success;
revenues from ADDERALL XR are subject to generic erosion and revenues from INTUNIV will become subject to generic competition starting in December 2014;
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 Rare Diseases 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;
investigations or enforcement action by regulatory authorities or law enforcement agencies relating to Shire’s activities in the highly regulated markets in which it operates may result in significant legal costs and the payment of substantial compensation or fines;
adverse outcomes in legal matters and other disputes, including Shire’s ability to enforce and defend patents and other intellectual property rights required for its business, could have a material adverse effect on Shire’s revenues, financial condition or results of operations;
Shire faces intense competition for highly qualified personnel from other companies, academic institutions, government entities and other organizations. Shire is undergoing a corporate reorganization and the consequent uncertainty could adversely impact Shire’s ability to attract and/or retain the highly skilled personnel needed for Shire to meet its strategic objectives;
failure to achieve Shire’s strategic objectives with respect to the acquisition of ViroPharma Incorporated may adversely affect Shire’s financial condition and results of operations;
the recommended combination with AbbVie Inc. ( “ AbbVie” ) is subject to a number of conditions, including approval by shareholders and regulators

and other risks and uncertainties detailed from time to time in Shire’s filings with the Securities and Exchange Commission, including those risks outlined in “Item 1A: Risk Factors” in Shire’s Annual Report on Form 10-K for the year ended December 31, 2013.
