“Praxis has entered a defining moment, with an exceptional CNS pipeline and the potential to launch multiple transformative medicines in the near term. What excites me most is the opportunity to help shape the company scale at speed and with discipline to deliver these medicines to patients around the world. Drawing on my experience commercializing medicines worldwide and building organizations through periods of rapid growth and change, I look forward to supporting Praxis in this next phase of it's evolution,” said Mr. Arbuckle.
