Fulcrum Therapeutics Launched with $55 Million to Reactivate the Fragile X Gene
A new company has launched that will invest tens of millions in reactivating the Fragile X gene. With $55 million in investment funds, Fulcrum Therapeutics in Cambridge, MA, aim to develop small molecules to control gene expression. These potential new treatments would be based on controlling genetic on- and off-switches of disease genes. Fulcrum will start with two diseases: Fragile X syndrome and a rare form of muscular dystrophy. FRAXA is funding one of the founding scientists, Jeannie Lee, MD, PhD, of Harvard University, and has been working with others on the new Fulcrum team.
