Shire Continues 20-Year Commitment to ADHD with New Research at 2017 Annual Meeting of American Psychiatric Association

Latest Research Supports Greater Understanding of the Evolving Needs of Adults with ADHD

Lexington, M.A. – May 16, 2017 Shire plc (LSE: SHP, NASDAQ: SHPG) will present research on the evolving needs of adults living with Attention-Deficit/Hyperactivity Disorder (ADHD) at the upcoming 170th Annual Meeting of the American Psychiatric Association (APA) in San Diego, California, from May 20-24, 2017.

“The data being presented this year at APA by Shire help us to better understand the needs of adults with ADHD, a disorder that can impair adults in home, social and work settings,” said Norman Atkins, Medical Lead for ADHD at Shire. “Based on our research, we understand that symptom burden can persist in adults with ADHD, including those who have been working with their healthcare professional to manage the disorder. We want to advance the understanding of the complex needs of adults with ADHD and how we can best address those.”

Results from the studies will provide important insights on symptom burden and the continued unmet need to more effectively identify ADHD and treat the condition in adults. Research will also be presented on SHP465 (mixed salts of a single-entity amphetamine product), an investigational agent currently under review with the U.S. Food and Drug Administration (FDA) as a potential treatment for ADHD. In addition, research will be presented on Vyvanse® (lisdexamfetamine dimesylate), an approved treatment option for patients six years old and above with ADHD. Vyvanse is not for weight loss. It is not known if Vyvanse is safe and effective for the treatment of obesity.

Specific presentations include:

IMPORTANT SAFETY INFORMATION

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

Vyvanse is a stimulant medicine. Tell the doctor if you or your child have ever abused or been dependent on alcohol, prescription medicines, or street drugs.

Who should not take Vyvanse?
Do not take Vyvanse if you or your child is:

  • taking or has taken an anti-depression medicine called a monoamine oxidase inhibitor (MAOI) within the past 14 days.
  • sensitive or allergic to, or had a reaction to other stimulant medicines.

Problems that can occur while taking Vyvanse. Tell the doctor:

  • if you or your child have heart problems or heart defects, high blood pressure, or a family history of these problems. This is important because sudden death has occurred in people with heart problems or defects taking stimulant medicines, and sudden death, stroke and heart attack have happened in adults taking stimulant medicines. Since increases in blood pressure and heart rate may occur, the doctor should regularly check these during treatment. Call the doctor right away if you or your child have any signs of heart problems such as chest pain, shortness of breath, or fainting while taking Vyvanse.
  • if you or your child have mental problems, or a family history of suicide, bipolar illness, or depression. This is important because new or worsening behavior and thought problems or bipolar illness may occur. New symptoms such as seeing or hearing things that are not real, believing things that are not true, being suspicious, or having new manic symptoms may occur. Call the doctor right away if there are any new or worsening mental symptoms during treatment.
  • if you or your child have circulation problems in fingers and toes (peripheral vasculopathy, including Raynaud’s phenomenon). Fingers or toes may feel numb, cool, painful, sensitive to temperature and/or change color from pale, to blue, to red. Call the doctor right away if any signs of unexplained wounds appear on fingers or toes while taking Vyvanse.
  • if your child is having slowing of growth (height and weight); Vyvanse may cause this serious side effect. Your child should have his or her height and weight checked often while taking Vyvanse. The doctor may stop treatment if a problem is found during these check-ups.
  • if you or your child are pregnant or plan to become pregnant. It is not known if Vyvanse may harm your unborn baby.
  • if you or your child are breastfeeding or plan to breastfeed. Do not breastfeed while taking Vyvanse. Talk to your doctor about the best way to feed your baby if you take Vyvanse.

What are possible side effects of Vyvanse?

The most common side effects of Vyvanse reported in ADHD studies include:

  • anxiety
  • decreased appetite
  • diarrhea
  • dizziness
  • dry mouth
  • irritability
  • loss of appetite
  • nausea
  • trouble sleeping
  • upper stomach pain

NOTES TO EDITORS

About ADHD

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that manifests as a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development and is inconsistent with developmental level.

Approximately 10.5 million adults and 6.4 million children in the U.S. are estimated to be living with ADHD. Approximately 50 to 66 percent of children with ADHD in childhood may continue to have ADHD symptoms as adults.

The specific etiology of ADHD is unknown. The diagnosis is made utilizing criteria specified in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-5®). Only a trained healthcare professional can evaluate and diagnose ADHD.

Although there is no cure for ADHD, there are accepted treatments that have been demonstrated to improve symptoms. Standard treatments include educational approaches, psychological therapies which may include behavioral modification and/or medication. Ongoing assessment and treatment may be necessary.

Statements included herein that are not historical facts, including without limitation statements concerning future strategy, plans, objectives, expectations and intentions, the anticipated timing of clinical trials and approvals for, and the commercial potential of, inline or pipeline products, 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, the following:

  • Shire’s products may not be a commercial success;
  • increased pricing pressures and limits on patient access as a result of governmental regulations and market developments may affect Shire’s 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 manufacture of Shire’s products is subject to extensive oversight by various regulatory agencies. Regulatory approvals or interventions associated with changes to manufacturing sites, ingredients or manufacturing processes could lead to, among other things, significant delays, an increase in operating costs, lost product sales, an interruption of research activities or the delay of new product launches;
  • certain of Shire’s therapies involve lengthy and complex processes, which may prevent Shire from timely responding to market forces and effectively managing its production capacity;
  • Shire has a portfolio of products in various stages of research and development. The successful development of these products is highly uncertain and requires significant expenditures and time, and there is no guarantee that these products will receive regulatory approval;
  • 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 affect Shire’s revenues, financial conditions or results of operations;
  • Shire’s products and product candidates face substantial competition in the product markets in which it operates, including competition from generics;
  • adverse outcomes in legal matters, tax audits 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 the Company’s revenues, financial condition or results of operations;
  • inability to successfully compete for highly qualified personnel from other companies and organizations;
  • failure to achieve the strategic objectives, including expected operating efficiencies, cost savings, revenue enhancements, synergies or other benefits at the time anticipated or at all with respect to Shire’s acquisitions, including NPS Pharmaceuticals Inc., Dyax Corp. or Baxalta Incorporated may adversely affect Shire’s financial condition and results of operations;
  • Shire’s growth strategy depends in part upon its ability to expand its product portfolio through external collaborations, which, if unsuccessful, may adversely affect the development and sale of its products;
  • a slowdown of global economic growth, or economic instability of countries in which Shire does business, as well as changes in foreign currency exchange rates and interest rates, that adversely impact the availability and cost of credit and customer purchasing and payment patterns, including the collectability of customer accounts receivable;
  • failure of a marketed product to work effectively or if such a product is the cause of adverse side effects could result in damage to Shire’s reputation, the withdrawal of the product and legal action against Shire;
  • 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;
  • Shire is dependent on information technology and its systems and infrastructure face certain risks, including from service disruptions, the loss of sensitive or confidential information, cyber-attacks and other security breaches or data leakages that could have a material adverse effect on Shire’s revenues, financial condition or results of operations;
  • Shire incurred substantial additional indebtedness to finance the Baxalta acquisition, which may decrease its business flexibility and increase borrowing costs; and
