Expansion Therapeutics - Jupiter, FL

Full-time$80,000 - $95,000 a year

Currently Seeking: Scientist, Biology (Jupiter, FL)

Company Overview

Founded in November 2016, Expansion Therapeutics, Inc. is a private company focused on the discovery and development of ribonucleic acid (RNA) targeted small molecule medicines. Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes. Expansion is focused on expansion repeat disorders, which are responsible for over 30 neurological and neuromuscular diseases, and for which there are currently no satisfactory therapies. Our initial disease focus, myotonic dystrophy type 1 (DM1), is the most frequent cause of adult onset muscular dystrophy.

Expansion Therapeutics’ proprietary technology is based on pioneering work from the lab of Dr. Matthew D. Disney of The Scripps Research Institute Florida. In January 2018, we closed $55.3 million in Series A financing, co-led by 5AM Ventures, Kleiner Perkins, Novartis Venture Fund, and Sanofi Ventures with participation from RA Capital Management and Alexandria Venture Investments. The financing will allow Expansion to advance our portfolio of novel RNA-targeted small molecule medicines to treat rare diseases.

With facilities in San Diego, California and Jupiter, Florida, Expansion Therapeutics currently employs 16 individuals in the U.S. It also has a seven-member board of directors, and six-member scientific advisory board comprised of leaders in the field of RNA-targeted small molecule chemistry and biology, RNA folding and structural biology.
