– U.S. FDA Grants Orphan Drug Designation for Investigational SHP647 for Treatment of Pediatric Patients with Moderately to Severely Active Crohn’s Disease

– Health Canada Grants Priority Review for Investigational Lanadelumab for Prevention of Angioedema Attacks in Patients 12 Years and Older with Hereditary Angioedema

Cambridge, Mass. – February 13, 2018 – Shire plc (LSE: SHP, NASDAQ: SHPG), the global biotechnology leader in rare diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to Shire’s investigational therapy, SHP647, for the treatment of pediatric patients with moderately to severely active Crohn’s disease. Shire is preparing to conduct Phase 3 trials investigating SHP647 for the treatment of moderately to severely active Crohn’s disease in adults. Pediatric study plans with SHP647 are currently under discussion with health authorities.

Health Canada has accepted Shire’s request for priority review for the New Drug Submission (NDS) for lanadelumab (SHP643), an investigational therapy for prevention of angioedema attacks in patients 12 years and older with hereditary angioedema (HAE). Health Canada’s review of the NDS under Priority Review is expected to be completed in the second half of 2018.

Pediatric onset Crohn’s disease presents often with a more complicated disease course compared to adults and can have an impact on patients’ growth, pubertal and emotional development.1 In the U.S., the prevalence of Crohn’s disease in the pediatric population is approximately 58 in 100,000.2

HAE is a rare, genetic disorder that results in recurring attacks of edema (swelling) in various parts of the body, including the abdomen, face, feet, genitals, hands and throat.3,4,5 The swelling can be debilitating and painful, resulting in significant impact on quality of life for those individuals with HAE.

U.S. FDA Orphan Drug status is intended to advance drug development for rare diseases. The FDA provides Orphan Drug Designation to drugs and biologics that demonstrate promise for the diagnosis and/or treatment of rare diseases or conditions that affect fewer than 200,000 people in the U.S.6

Priority review status is granted by Health Canada to a NDS for serious, life-threatening or severely debilitating diseases or conditions for which there is substantial evidence of clinical effectiveness that the drug provides an effective treatment, prevention or diagnosis of a disease or condition for which no drug is currently marketed in Canada; or a significant increase in efficacy and/or significant decrease in risk such that the overall benefit/risk profile is improved over existing therapies, preventatives or diagnostic agents for a disease or condition that is not adequately managed by a drug marketed in Canada.7

About SHP647
SHP647 is a fully human IgG2 monoclonal antibody targeting the mucosal vascular addressin cell adhesion molecule-1 (MAdCAM-1). MAdCAM-1 plays a role in leukocyte trafficking in the GI tract and also appears to facilitate excessive lymphocyte infiltration under conditions of chronic GI inflammation. Shire is currently investigating SHP647 in Phase 3 studies for the treatment of moderately to severely active ulcerative colitis, a form of inflammatory bowel disease, in adults. Shire is also preparing to conduct Phase 3 trials investigating SHP647 for the treatment of moderately to severely active Crohn’s disease in adults. Pediatric study plans with SHP647 are currently under discussion with health authorities. In November 2017, SHP647 received Orphan Drug Designation from the U.S. FDA for the treatment of pediatric patients with moderately to severely active ulcerative colitis.

About Lanadelumab
Lanadelumab is an investigational fully human monoclonal antibody that specifically binds and inhibits plasma kallikrein8 and is being studied as a treatment for the prevention of angioedema attacks in patients 12 years and older with HAE. Lanadelumab is formulated for subcutaneous administration, and has a half-life of approximately 14 days in patients with HAE.9

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

Statements included herein that are not historical facts, including without limitation statements concerning future strategy, plans, objectives, expectations and intentions, projected revenues, 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 depends on third parties to supply certain inputs and services critical to its operations including certain inputs, services and ingredients critical to its manufacturing processes. 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;
  • the nature of producing plasma-based therapies 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;
