About Us

Our mission is to prevent repeat expansion disorders and ensure a future for our patients

We are developing a fundamentally different treatment for repeat expansion disorders — including Huntington’s disease, myotonic dystrophy and spinocerebellar ataxias — by addressing the underlying cause of the genetic dysfunction that drives disease onset and progression.

To accomplish this goal, we’ve assembled a team with decades of expertise across drug discovery, genetics, clinical research and operations. We’re supported by a top-tier syndicate of investors who share our commitment to transforming the lives of patients and families affected by repeat expansion disorders.
