Expansion Therapeutics, Inc.

Jupiter, FL, United States

Expansion Therapeutics is a drug discovery and development company pursuing the vast potential of
small molecule medicines for RNA‐mediated diseases. We are initially focused on expansion repeat
disorders, a set of ~30 genetic diseases for which there are no satisfactory therapies. Our lead disease
focus, myotonic dystrophy type 1 (DM1), is the most frequent cause of adult onset muscular dystrophy.
Expansion has assembled an initial focused pipeline of compositions targeting repeats that drive a
number of expansion repeat disorders.


Perform research in the laboratory as a synthetic and medicinal chemist applying the latest knowledge and techniques in the field. Advance the assigned program and contribute to the identification of a lead or development candidate.
