Pioneers in Modulating Gene and Protein Expression
Challenging what's possible
Harnessing groundbreaking science for patients has led to many firsts – the first approved treatment for Duchenne in the world, the first approved gene therapy directly infused into the brain, and the first approved small molecule splicing modifier. Our innovative pipeline continues to expand as we discover and develop treatments using the newest technologies available.
