November 4, 2016

16 presentations to highlight innovation in hematology, oncology and genetic diseases

Lexington, Mass. – November 4, 2016 – Shire plc (LSE: SHP, NASDAQ: SHPG), the leading global biotechnology company focused on serving individuals with rare diseases, announced today the depth and breadth of the data it will be presenting at the 58th American Society of Hematology (ASH) Annual Meeting, taking place December 3-6 in San Diego, California. The company’s robust research in hematology, oncology and genetic disease will be showcased in 4 oral presentations and 12 poster presentations.

"Shire’s extensive presence at ASH 2016 reinforces our commitment to discovering and delivering transformative treatments for patients with rare conditions," said Philip J. Vickers, Ph.D., Head of Research and Development, Shire. "We aim to continually lead the scientific dialogue for rare hematologic research and address some of the most urgent unmet needs for patients facing these challenging diseases."

HEMATOLOGY
Data in hematology, the largest portfolio for the company, will focus on research that continues to build on the proven approach of direct factor replacement as the global standard of care for hemophilia. Data presentations will showcase the continued growth of the portfolio and new strategies to improve outcomes for people with hemophilia and other bleeding conditions. The company will also present research on several of its promising early- and late-stage pipeline programs:

ONCOLOGY
As part of Shire’s focus on serving individuals with rare diseases, the company is committed to addressing unmet needs in areas of oncology where patients and providers have limited treatment options. Shire has pipeline assets and research targets for rare cancers including metastatic pancreatic cancer, colorectal cancer and targets in checkpoint inhibitors and allogeneic CAR-T, as well as a biologic treatment approved as part of a multi-agent chemotherapeutic regimen for the treatment of acute lymphocytic leukemia (ALL), ONCASPAR^TM (pegaspargase), that is approved by the U.S. Food & Drug Administration (FDA) and all 27 EU member states. Data presented at ASH will include a focus on pegaspargase as a therapeutic option for ALL.

GENETIC DISEASE
Shire is also dedicated to helping patients with inherited illnesses. Type I Gaucher disease is a rare, inherited metabolic condition, and the most common of a family of rare diseases known as lysosomal storage disorders (LSDs). It affects approximately 1 in 50,000 to 1 in 100,000 people in the general population, and 1 in 855 people in the Ashkenazi Jewish community. Every type I Gaucher patient is unique and will experience varying symptoms and degrees of disease severity, making type I Gaucher disease difficult to diagnose. To this end, Shire will be hosting an engaging, case-based presentation to raise disease awareness:

Product Theater: Julie M: A Diagnostic Journey. Monday, Dec. 5, 12:15 p.m. to 1:15 p.m.

Important Information for ADYNOVATE [Antihemophilic Factor (Recombinant), PEGylated]

Indications
ADYNOVATE, [Antihemophilic Factor (Recombinant), PEGylated], is a human antihemophilic factor indicated in adolescent and adult patients (12 years and older) with hemophilia A (congenital factor VIII deficiency) for:

On-demand treatment and control of bleeding episodes
Routine prophylaxis to reduce the frequency of bleeding episodes

ADYNOVATE is not indicated for the treatment of von Willebrand disease.

DETAILED IMPORTANT RISK INFORMATION

CONTRAINDICATIONS
ADYNOVATE is contraindicated in patients who have had prior anaphylactic reaction to ADYNOVATE, to the parent molecule (ADVATE), mouse or hamster protein, or excipients of ADYNOVATE (e.g. Tris, mannitol, trehalose, glutathione, and/or polysorbate 80).

WARNINGS & PRECAUTIONS
Hypersensitivity Reactions
Hypersensitivity reactions are possible with ADYNOVATE. Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with other recombinant antihemophilic factor VIII products, including the parent molecule, ADVATE. Early signs of hypersensitivity reactions that can progress to anaphylaxis may include angioedema, chest tightness, dyspnea, wheezing, urticaria, and pruritus. Immediately discontinue administration and initiate appropriate treatment if hypersensitivity reactions occur.

Neutralizing Antibodies
Formation of neutralizing antibodies (inhibitors) to factor VIII can occur following administration of ADYNOVATE. Monitor patients regularly for the development of factor VIII inhibitors by appropriate clinical observations and laboratory tests. Perform an assay that measures factor VIII inhibitor concentration if the plasma factor VIII level fails to increase as expected, or if bleeding is not controlled with expected dose.

ADVERSE REACTIONS
Common adverse reactions (≥1% of subjects) reported in the clinical studies were headache and nausea.

Important Information for ADVATE [Antihemophilic Factor (Recombinant)]

Indications
ADVATE [Antihemophilic Factor (Recombinant)] is a recombinant antihemophilic factor indicated for use in children and adults with hemophilia A (congenital factor VIII deficiency) for:

Control and prevention of bleeding episodes
Perioperative management
Routine prophylaxis to prevent or reduce the frequency of bleeding episodes

ADVATE is not indicated for the treatment of von Willebrand disease.

DETAILED IMPORTANT RISK INFORMATION

CONTRAINDICATIONS
ADVATE is contraindicated in patients who have life-threatening hypersensitivity reactions, including anaphylaxis, to mouse or hamster protein or other constituents of the product.

WARNINGS & PRECAUTIONS
Hypersensitivity Reactions
Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with ADVATE. Symptoms include dizziness, paresthesia, rash, flushing, facial swelling, urticaria, dyspnea, pruritus, and vomiting. Discontinue ADVATE if hypersensitivity symptoms occur and administer appropriate emergency treatment.

Neutralizing Antibodies
Neutralizing antibodies (inhibitors) have been reported following administration of ADVATE predominantly in previously untreated patients (PUPs) and previously minimally treated patients (MTPs). Monitor all patients for the development of factor VIII inhibitors by appropriate clinical observation and laboratory testing. If expected plasma factor VIII activity levels are not attained, or if bleeding is not controlled with an expected dose, perform an assay that measures factor VIII inhibitor concentration.

ADVERSE REACTIONS
Serious adverse reactions seen with ADVATE are hypersensitivity reactions, including anaphylaxis, and the development of high-titer inhibitors necessitating alternative treatments to factor VIII. The most common adverse reactions observed in clinical trials (frequency ≥5% of subjects) were pyrexia, headache, cough, nasopharyngitis, arthralgia, vomiting, upper respiratory tract infection, limb injury, nasal congestion, and diarrhea.
