STRIDE Data Show Translarna™ Delays Loss of Ambulation by More Than Five Years in Boys with Nonsense Mutation Duchenne Muscular Dystrophy
"The five-year analysis of the STRIDE registry clearly demonstrates Translarna's profound impact on changing the course of disease progression, said
A time-to-event analysis of five years of registry data, presented at the
The median age that boys treated with Translarna reached a predicted forced vital capacity (FVC) lower than 60% was 17.6 years old, compared with 15.8 years old for those who did not receive Translarna. This delay in loss of lung function is critical, as the sub-60% threshold is considered the milestone at which patients usually start to require respiratory physical therapy.
"Watching your child losing his abilities, until he can no longer walk or even breathe without help is heartbreaking," said
The analysis is based on results from 241 boys in 13 countries who were enrolled in the STRIDE patient registry over the past five years.[1] The data was compared with natural history from a propensity-score matched cohort in a long-term natural history study (the
Translarna continues to be well tolerated in nmDMD patients, and the safety results, representing 1059 patient-years of exposure, remain consistent with the therapy's known safety profile.
About Translarna™ (ataluren)
Translarna (ataluren), discovered and developed by PTC Therapeutics, Inc., is a protein restoration therapy designed to enable the formation of a functioning protein in patients with genetic disorders caused by a nonsense mutation. A nonsense mutation is an alteration in the genetic code that prematurely halts the synthesis of an essential protein. The resulting disorder is determined by which protein cannot be expressed in its entirety and is no longer functional, such as dystrophin in
Duchenne muscular dystrophy. Translarna, the tradename of ataluren, is licensed in the European
Economic Area for the treatment of nonsense mutation Duchenne muscular dystrophy in ambulatory patients aged two years and older. Ataluren is an investigational new drug in the United States.
About the STRIDE Registry
The STRIDE (Strategic Targeting of Registries and International Database of Excellence) Registry is an ongoing, multicenter, observational study of the safety and effectiveness of Translarna in routine care. It is the first patient data repository to provide real-world experience regarding the long-term use of Translarna in routine clinical practice. Enrolled patients will be followed for at least five years from the date of enrollment, or until withdrawal from the study.2 As of
STRIDE is a collaborative partnership between TREAT-NMD and
The Registry also fulfills a post-marketing commitment to the
About Duchenne Muscular Dystrophy (Duchenne)
Primarily affecting males, Duchenne is a rare and fatal genetic disorder that results in progressive muscle weakness from early childhood and leads to premature death in the mid-20's due to heart and respiratory failure. It is a progressive muscle disorder caused by the lack of functional dystrophin protein. Dystrophin is critical to the structural stability of all muscles, including skeletal, diaphragm, and heart muscles. Patients with Duchenne can lose the ability to walk (loss of ambulation) as early as 10 years old, followed by loss of the use of their arms. Duchenne patients subsequently experience life-threatening lung complications, requiring the need for ventilation support, and heart complications in their late teens and 20's.
More information regarding Duchenne is available through the Muscular Dystrophy Association and the Parent Project Muscular Dystrophy. Additionally, information and resources are available at www.duchenneandyou.com.
