What is
Elaprase?

This website is intended for healthcare professionals outside of the US and UK

Elaprase is indicated for the long-term treatment of patients with Hunter syndrome (Mucopolysaccharidosis II, MPS II). Heterozygous females were not studied in the clinical trials.1 Hunter syndrome patients have mutations in the IDS gene which encodes iduronate-2-sulfatase (I2S), an enzyme necessary for the break-down of mucopolysaccharides (glycosaminoglycans (GAGs)). Without the I2S enzyme, GAGs accumulate in the cells, tissues and organs of MPS II patients resulting in a variety of symptoms associated with Hunter syndrome.2 A formulation of I2S, Elaprase is produced by recombinant DNA technology in a human cell line, and provides a disease specific form of enzyme replacement therapy (ERT).3 For more than a decade, Elaprase has provided patients with a treatment option that has been shown to improve many of the somatic signs and symptoms of Hunter syndrome.

The Hunter Outcome Survey

The Hunter Outcome Survey (HOS) was established as a long-term, open-ended, multicentre, global registry designed to collect information on patients with Hunter syndrome and to address the post-approval commitments of Elaprase. The HOS has been collecting real-world data on the clinical presentation and progression of Hunter syndrome during routine assessments for over ten years. The objectives of this registry are to gather information on the effectiveness and safety of Elaprase treatment and to clarify the disease progression in MPS II patients.4

10 years of Elaprase

2017

An analysis was carried out to compare the survival data of Elaprase treated and untreated patients identified that Elaprase treatment significantly improved the survival of MPS II patients by an average of 11.8 years and reduced the risk of mortality by 54%.5

2016

As of July 2016, 1200 patients, from 134 clinics, in 33 countries had been enrolled in the HOS, making it the largest global source of data on Hunter syndrome.5

2015

The shelf-life of Elaprase was extended from 2 years to 3 years as demonstrated by the SmPC update.1

2014

Elaprase cited as ERT treatment for Hunter syndrome in guidelines for Latin America.6

2013

HOS study results focusing on the effect of Elaprase in MPS II growth rates were published.7

2012

The publication of the expert panel consensus on the use of Elaprase treatment in severe MPS II patients.8

2011

Elaprase cited as ERT for treatment of Hunter syndrome in European Guidelines.9

An analysis of HOS data on the safety and effectiveness of Elaprase use in patients younger than 6 years old found Elaprase had a similar safety profile in these patients permitting the early initiation of treatment in MPS II patients, which is important for treating this progressive disease.10

2010

Analysis of HOS data confirmed that, taking into consideration appropriate factors, it is feasible for Hunter syndrome patients, including those who are severely affected, to receive ERT infusions at home.11

2009

A report on the mortality and causes of death of untreated Hunter syndrome patients was published.12

2008

The initial report from the HOS was published after following 263 Hunter syndrome patients.4

2007

Elaprase received approval in Europe in 2007.13

2006

Elaprase received FDA approval in the USA.14

2005

The HOS is set up to gather data on Hunter syndrome patients receiving ERT.4
