GlaxoSmithKline's Duchenne MD exon-skipping drug moves into a phase 3 trial and is renamed drisapersen; "block skipping" of exons 45-55 in mice looks promising

Exon skipping is an experimental therapeutic strategy in which regions — exons — of a gene are targeted and blocked ("skipped") by laboratory-designed molecules. The goal is that the remaining genetic instructions will lead to production of a shorter but still-functional protein.

A phase 2 trial of GSK2402968, designed to treat Duchenne MD caused by specific mutations, is now recruiting at 14 sites
