Rare Disease Status Given to Duchenne Therapy
FDA has granted Wave Life Sciences a rare pediatric disease designation for WVE-N531 and its use in treating boys with Duchenne muscular dystrophy who are amenable to exon 53 skipping. The therapy is currently being evaluated in the registrational FORWARD-53 clinical trial, and the company says it expects release data, including dystrophin protein expression from muscle biopsies after 24 weeks of treatment, in the third quarter of this year.
WVE-N531 is described as an exon-skipping oligonucleotide designed to induce the production of endogenous, functional dystrophin protein. Previously released study data showed that the therapy “achieved industry-leading mean exon skipping levels of 53%,” the company says.
