Therapeutic Approach

Restoring or Replacing Dystrophin

One of the most common types of mutations in the dystrophin gene occurs when a piece of the code in the middle of the gene is missing or deleted. By skipping additional segments of the dystrophin code called exons, the deletion can shift from an out-of-frame deletion to an in-frame deletion. Typically, an in-frame deletion results in a smaller, but still functional, dystrophin protein. This shortened protein is expected to act in a similar way to normal dystrophin, and so relieve some symptoms of Duchenne and hopefully result in a milder presentation. Dyne-251 is an exon skipping therapy bound to an antigen-binding fragment (Fab) to help the therapy reach the muscle cells for those amenable to exon 51 skipping.


A Phase 1/2 study is currently recruiting.
