About Stoke Therapeutics
Stoke Therapeutics is a
biotechnology company that is pioneering a new way to treat the
underlying causes of severe genetic diseases by precisely upregulating
protein expression to restore target proteins to near normal levels.
Stoke aims to develop the first precision medicine platform to target
the underlying cause of a broad spectrum of genetic diseases in which
the patient has one healthy copy of a gene and one mutated copy that
fails to produce a protein essential to health. These diseases, in which
loss of approximately 50 percent of normal protein expression causes
disease, are called autosomal dominant haploinsufficiencies. Stoke was
launched with investments by Apple Tree Partners. Stoke is headquartered
in Bedford, Massachusetts with offices in Cambridge, Massachusetts.
