Top Companies At The Forefront Of RNA Therapeutics Development

Let's start with the first approval of antisense drug for treating Spinal Muscular Atrophy (SMA), Spinraza, announced in 2016. SMA is a fatal neurodegenerative disease caused by a malfunctioning of SMN2 protein -- it affects on average 1 in every 10.000 people globally. Researchers from Ionis and Biogen managed to reverse the effect of the genetic error at the stage of RNA splicing. The drug works through binding to the target mRNA sequence forcing exon, which is being skipped by an error in the genome, to be translated into a full-length protein. Approval of Spinraza has changed the situation with RNA-targeted therapies, resurging the field which was largely abandoned by investors in the mid-2000s. In 2016 the market was also replenished with Exondys 51, a drug by Sarepta Therapeutics, targeting Duchenne Muscular Dystrophy (DMD).
