Role summary

Stoke Therapeutics is seeking a Senior Director of Toxicology to lead nonclinical safety studies for genetic disease treatments. This role involves designing, executing, and interpreting toxicology studies, managing CROs, and preparing regulatory documents (INDs, CTAs, NDAs).

Experience with oligonucleotides and drug development in CNS/eye is preferred. This hybrid position requires 7+ years of industry experience and reports to the Chief Scientific Officer.

About Stoke:

Stoke Therapeutics (Nasdaq: STOK), is a biotechnology company dedicated to restoring protein expression by harnessing the body’s potential with RNA medicine. Using Stoke’s proprietary TANGO (Targeted Augmentation of Nuclear Gene Output) approach, Stoke is developing antisense oligonucleotides (ASOs) to selectively restore naturally-occurring protein levels. Stoke’s first medicine in development, zorevunersen, has demonstrated the potential for disease modification in patients with Dravet syndrome and is currently being evaluated in a Phase 3 study. Stoke’s initial focus are diseases of the central nervous system and the eye that are caused by a loss of ~50% of normal protein levels (haploinsufficiency). Proof of concept has been demonstrated in other organs, tissues, and systems, supporting broad potential for Stoke’s proprietary approach. Stoke is headquartered in Bedford, Massachusetts.
