The authorisation is based on the safety and efficacy results from a randomised double-blind multicentre study in 174 nmDMD patients for 48 weeks and additional retrospective analyses of study data from the company.

The study’s primary endpoint evaluated the effect of Translarna on ambulation as assessed by the change in distance walked (six-minute walk distance – 6MWD) during a six-minute walk test (6MWT).

Based on the post-hoc analysis, patients receiving Translarna (40 mg/kg/day given in three doses) had a 12.9m mean decline in 6MWD from baseline to week 48, and patients receiving placebo had a 44.1m mean decline in 6MWD.

In addition, patients receiving the treatment showed better improvement in secondary end points such as stair climb and stair descend time-function tests.
