"We are excited to see that the CHMP adopted the positive opinion for this label modification allowing patients who become non-ambulatory to continue to use Translarna," said
Translarna is the only treatment for the underlying cause of Duchenne caused by a nonsense mutation and works by restoring dystrophin production.1,2 It is approved by the EMA for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD) in ambulatory patients aged two years and older. Real world evidence and clinical trials have demonstrated the potential of Translarna to slow disease progression and improve outcomes before and beyond loss of ambulation:
- In a long-term, open-label extension study (Study 019), Translarna preserved lung function in non-ambulatory patients for an additional four years compared with patients treated with standard of care from a long-term natural history study (the
Cooperative International Neuromuscular Research Group(CINRG) natural history database of Duchenne patients).3
- Data from the STRIDE Registry, the first international drug registry for Duchenne patients receiving Translarna, demonstrated that boys treated with Translarna and standard of care (SoC) preserved the ability to walk for years longer than those on SoC alone, as well as experienced a slower decline in lung function.4
- Children treated with Translarna in a real-world setting as part of the STRIDE registry were able to walk independently for an additional 3.5 years compared with a propensity-score matched cohort in the CINRG natural history study, with a median age at loss of ambulation of 14.5 years and 11 years, respectively (72% relative risk reduction).4
- There was a trend toward a delay in the age at decline in pulmonary function in STRIDE patients compared with CINRG patients, as measured by predicted FVC < 50% and FVC < 1 L.4
- These data suggest that treatment with ataluren in addition to SoC may delay loss of ambulation, as well as pulmonary functional decline, in patients with nmDMD.

About Duchenne muscular dystrophy
Primarily affecting males, Duchenne muscular dystrophy (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-twenties 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 age ten, 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 twenties.
