CUVITRU [Immune Globulin Subcutaneous (Human), 20% Solution] Data Demonstrate Improved Treatment Satisfaction Relative to Patients' Previous Immunoglobulin Therapy

LEXINGTON, Massachusetts, March 6, 2017 /PRNewswire/ --

Shire plc (LSE: SHP, NASDAQ: SHPG), the global leader in rare diseases and highly specialized conditions, will present data assessing primary immunodeficiency (PI) patient treatment satisfaction with CUVITRU [Immune Globulin Subcutaneous (Human), 20% Solution] at the American Academy of Allergy, Asthma & Immunology (AAAAI) annual meeting in Atlanta, Georgia, March 3-6, 2017. PI is a group of more than 300 disorders in which part of the body's immune system is missing or does not function properly, in many cases making it more difficult to fight off infections.^[1],[2] It is estimated that as many as six million children and adults may be affected by PI worldwide.^[3]

CUVITRU was approved by the U.S. Food and Drug Administration (FDA) in September 2016, and is the latest addition to Shire's comprehensive immunoglobulin (IG) therapy portfolio. CUVITRU offers a customizable treatment option that can be tailored to patient and physician preference. It is the only 20% subcutaneous IG (SCIG 20%) treatment option with the ability to infuse up to 60 mL (12 grams) per site and up to 60 mL per hour per site, as tolerated.

"Shire is focused on innovating on behalf of patients with PI so they can more easily manage their condition," said Paul Blanchfield, U.S. Head of Immunology, Shire. "CUVITRU allows for fewer infusion sites and shorter infusion durations than other conventional SCIG options, without compromising on efficacy or safety. We hope this means an improved overall treatment experience for PI patients and greater flexibility in managing their condition."

Shire has five poster presentations at AAAAI and will host two symposia featuring clinical immunology experts discussing the importance of customizing PI treatment options to the individual patient and elevating the standard of care.

"Many patients require IG replacement therapy throughout their lives, making it important to consider the patient's experience in addition to the treatment's ability to limit or reduce infections," said Mark R. Stein, MD, FAAAAI, Medical Director at Allergy Associates of the Palm Beaches. "These data advance our understanding of how we can best support patients throughout their PI journey."

Highlights of Shire's Presentations at AAAAI 

Improved Treatment Satisfaction with a New Human Subcutaneous Immunoglobulin (SCIG 20%) in Patients Previously Treated with IVIG 

This analysis compares the treatment satisfaction of patients with PI during the two CUVITRU pivotal studies (North American and European) after the IVIG and CUVITRU treatment period.   Treatment satisfaction was assessed using the Life Quality Index (LQI) instrument following the IVIG and CUVITRU periods among patients who were treated with IVIG prior to the study.  Results demonstrated that after 12 months on CUVITRU, patients reported statistically significant improvements in the Treatment Interference and the Therapy Setting domains of the LQI compared with the IVIG treatment period (3 months) in both the North American and European pivotal studies.  

Analysis of Safety and Tolerability Data in Pediatric Patients with Primary Immunodeficiency Diseases from Two Phase 2/3 Studies of Human Immune Globulin Subcutaneous, 20% 

An analysis of two Phase 2/3 clinical trials of CUVITRU in North America and Europe assessed the combined safety and tolerability data in pediatric patients with PI. A total of 39 patients between the ages of 2 and 16 received weekly CUVITRU infusions for ~1 year. Serious adverse events (SAEs), rates of local/systemic adverse reactions (ARs) defined as causally-related AEs, and infusion characteristics were analyzed. Results demonstrated that CUVITRU was well tolerated at high infusion rates and volumes per site with short infusion durations.

Review of the Onboarding Experience of a New 20% Human Immune Globulin for Subcutaneous Administration (SCIG 20%): Correlation of Infusion Parameters and Adverse Events (AEs) 

Data from a Phase 2/3 North American clinical trial of CUVITRU provided an opportunity to examine the onboarding experience of patients with PI to CUVITRU. In the trial, patients (3-83 years) received weekly CUVITRU infusions for ~1.3 years. As tolerated, volumes up to 60 mL/site and rates up to 60 mL/hr/site were infused, and associations between the rate of causally-related local AEs and the infusion parameters were investigated. Of the 77 patients enrolled, 53 (69%) had no previous SCIG experience. Results showed that the percent of patients who experienced causally-related local AEs during onboarding was low, which decreased and remained low over time. The rate of local AEs was not associated with faster infusion rates or increasing volumes per site with CUVITRU.  

Shire's other data presentations at AAAAI include:

• A New Subcutaneous Immunoglobulin 20% Formulation (SCIG 20%) with Individualized Infusion Parameters Resulted in a Positive Safety and Tolerability Profile in Patients with PIDD in Europe and North America 
• Analyses of a Subset of Patients with Primary Immunodeficiency Diseases (PIDD) who Switched Modes of Administration of Immunoglobulin (Ig) Therapy During Three Consecutive Studies 

In addition to approval of CUVITRU from the FDA, Shire also received successful completion of a decentralized procedure to support approval of CUVITRU by 17 authorities in Europe in June 2016. CUVITRU is now available in the U.S. and Switzerland; the company expects to initiate additional global regulatory submissions for CUVITRU throughout 2017 and 2018.

About Primary Immunodeficiency 

Primary immunodeficiencies (PI) are a group of more than 300 disorders in which part of the body's immune system is missing or does not function properly.^[1] Normally, the immune system protects the body from pathogenic microorganisms like bacteria, viruses, and fungi, which can cause infectious diseases. When any part of a person's immune system is absent or dysfunctional, the individuals are susceptible to infections, and it may take longer to recover from infections. When a defect in the immune system is inherited and genetically determined, it is called primary immune deficiency.^[2] It is estimated that as many as six million children and adults may be affected by PI worldwide.^[3]

About CUVITRU [Immune Globulin Subcutaneous (Human), 20% Solution] 

CUVITRU is an Immune Globulin Subcutaneous (Human) (IGSC), 20% Solution indicated as replacement therapy for primary humoral immunodeficiency (PI) in adult and pediatric patients two years of age and older.

CUVITRU is for subcutaneous infusion only. 

IMPORTANT SAFETY INFORMATION 

BOXED WARNING: THROMBOSIS 

Thrombosis may occur with immune globulin products, including CUVITRU. Risk factors may include: advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling vascular catheters, hyperviscosity and cardiovascular risk factors. 

For patients at risk of thrombosis, administer CUVITRU at the minimum dose and infusion rate practicable. Ensure adequate hydration in patients before administration. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk of hyperviscosity. 

CONTRAINDICATIONS 

CUVITRU is contraindicated in patients who have had an anaphylactic or severe systemic hypersensitivity reaction to the subcutaneous administration of human immune globulin and in IgA-deficient patients with antibodies against IgA and a history of hypersensitivity to human immune globulin treatment.

WARNINGS and PRECAUTIONS 

Hypersensitivity: Severe hypersensitivity reactions may occur, even in patients who have tolerated previous treatment with human immune globulin. IgA-deficient patients with antibodies to IgA are at greater risk of developing potentially severe hypersensitivity and anaphylactic reactions.

Renal Dysfunction/Failure: Monitor renal function and urine output and consider lower, more frequent dosing in patients who are at risk of developing renal dysfunction because of pre-existing renal insufficiency or predisposition to acute renal failure.

Thrombosis: Monitor for signs and symptoms of thrombosis and assess blood viscosity for those at risk for hyperviscosity.

Aseptic Meningitis Syndrome (AMS): Monitor for clinical signs and symptoms of AMS.

Hemolysis: Monitor for clinical signs and symptoms of hemolysis and delayed hemolytic anemia.

Transfusion-Related Acute Lung Injury (TRALI): Monitor for pulmonary adverse reactions associated with TRALI.

Transmittable Infectious Agents: Because CUVITRU is made from human plasma, it may carry a risk of transmitting infectious agents, such as viruses and other pathogens. No confirmed cases of transmission of viral diseases or variant Creutzfeldt-Jakob disease (vCJD) have been associated with CUVITRU.

Interference with Laboratory Tests: False positive serological test results, with the potential for misleading interpretation, may occur as the result of passively transferred antibodies.

ADVERSE REACTIONS 

The most common adverse reactions observed in clinical trials in ? 5% of patients were: local adverse reactions, systemic adverse reactions including headache, nausea, fatigue, diarrhea, and vomiting.
