Shire Announces FDA Approval for Label Expansion of CINRYZE® (C1 esterase inhibitor [human]) for Prevention of Attacks in Pediatric Hereditary Angioedema Patients
Dublin, Ireland - Thursday, June 21, 2018 - Shire plc (LSE: SHP, NASDAQ: SHPG), the leading global biotechnology company focused on rare diseases, today announced that the U.S. Food and Drug Administration (FDA) has approved a label expansion for CINRYZE® (C1 esterase inhibitor [human]), making it available to help prevent angioedema attacks in children aged 6 years and older with hereditary angioedema (HAE). CINRYZE has been approved in the U.S. since October 2008 for routine prophylaxis against attacks in adolescents and adults living with HAE.
HAE is a rare, genetic disorder estimated to affect about 1 in 10,000 to 1 in 50,000 people worldwide., The condition results in recurring attacks of edema (swelling) in various parts of the body, including the abdomen, face, feet, genitals, hands and throat that can be can debilitating and painful.2,, Attacks that obstruct the airways (laryngeal attacks) are potentially life-threatening due to the risk of asphyxiation.2,4,5
Andreas Busch, Ph.D., Executive Vice President, Head of Research and Development at Shire said: "Symptoms of HAE often present in childhood with the average child experiencing their first HAE attack around the age of 10. With the FDA label expansion of CINRYZE, children as young as 6 years old living with HAE now have the first FDA approved treatment option available to help prevent attacks."
The approval was based on data from a dedicated Phase 3 multicenter single-blind study (0624-301) that evaluated the use of CINRYZE in 12 patients living with HAE aged 7 to 11. Compared to the baseline observational period, the mean reduction in the normalized number of attacks for CINRYZE 500 U and CINRYZE 1,000 U was 71.1% and 84.5%, respectively. Both doses lessened the severity of attacks and reduced the use of acute treatment compared to baseline. The adverse reactions were headache, nausea, pyrexia (fever), and infusion site erythema (redness of the skin). None of these adverse reactions were severe, and none led to discontinuation (n=12, ages 7-11).1
"This news is exciting for the HAE community because those living with HAE who are as young as 6 have a new option to help prevent attacks," said Anthony Castaldo, President of the U.S. Hereditary Angioedema Association.
In March 2017, CINRYZE was granted European Commission (EC) approval for the label expansion granting three new indications, including routine prevention of angioedema attacks in children (ages 6 years and above) with severe and recurrent attacks of HAE.
About the CINRYZE Pediatric Study
Overall the safety and tolerability of CINRYZE has been shown to be similar in clinical studies of pediatric, adolescent and adult patients with HAE.
In Europe, CINRYZE is the first and only C1-Esterase Inhibitor (C1-INH) therapy approved for routine prevention in children, adolescents, and adults with HAE. CINRYZE is also approved for acute treatment and pre-procedure prevention of angioedema attacks.
IMPORTANT SAFETY INFORMATION (U.S. ONLY)
Contraindications: CINRYZE is contraindicated in patients who have manifested life-threatening immediate hypersensitivity reactions, including anaphylaxis, to the product.
Hypersensitivity Reactions: Severe hypersensitivity reactions may occur during or after administration of CINRYZE. Consider treatment methods carefully, because hypersensitivity reactions may have symptoms similar to HAE attacks. In case of hypersensitivity, discontinue CINRYZE infusion and institute appropriate treatment. Have epinephrine immediately available for treatment of an acute severe hypersensitivity reaction.
Thromboembolic Events: Serious arterial and venous thromboembolic (TE) events have been reported at the recommended dose of C1 Esterase Inhibitor (Human) products, including CINRYZE, following administration in patients with HAE. Risk factors may include presence of an indwelling venous catheter/access device, prior history of thrombosis, underlying atherosclerosis, use of oral contraceptives, certain androgens, morbid obesity, and immobility. Benefits of CINRYZE for routine prophylaxis of HAE attacks should be weighed against the risks of TE events in patients with underlying risk factors. Monitor patients with known risk factors for TE events during and after CINRYZE administration.
Transmissible Infectious Agents: Because CINRYZE is made from human blood, it may carry a risk of transmitting infectious agents, e.g. viruses, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. ALL infections thought by a physician possibly to have been transmitted by CINRYZE should be reported to Shire Medical Information at
Adverse Reactions: The only serious adverse reaction observed in clinical studies of CINRYZE was cerebrovascular accident. The most common adverse reactions (greater than or equal to 5%) observed were headache, nausea, rash, vomiting, and fever. Post marketing adverse reactions include local infusion site reactions and hypersensitivity. Post marketing thromboembolic events have been reported, including catheter-related and deep venous thromboses, transient ischemic attack, and stroke.
