Good news for the Duchenne Muscular Dystrophy (DMD) community. On June 8th, BioMarin announced the filing of a Marketing Authorization Application to the European Medicines Agency for Drisapersen, an antisense-mediated exon 51-skipping compound able to target the most prevalent genetic mutations responsible for the lack of production of functional dystrophin. The European filing follows the submission of a New Drug Application to the US FDA for Drisapersen back in April 2015.
Normally, dystrophin bridges cytoskeletal proteins to extracellular matrix and stabilises muscle fibres during contraction. The lack of its production in DMD leads to muscle damage, progressive muscle wasting, severe disability and premature death between the second and third decades due to cardiac or respiratory failure.
