“I am excited to join the Company at such a dynamic time in our journey and energized to work with the team to expedite progress on our two lead clinical programs in Giant Axonal Neuropathy (GAN) and Rett syndrome, as well as further strengthen our strategic partnership with Astellas,” said Mr. Nolan. “2023 is a crucial year for Taysha and it is imperative that we precisely execute as an organization on delivering key clinical and regulatory milestones as we endeavor to bring transformative therapies to patients and families suffering from devastating diseases.”

Mr. Nolan continued, “On behalf of the entire Board, we thank RA for his many contributions since founding Taysha in 2019 and successfully guiding the Company through its seed and crossover funding, the initial public offering, advancing multiple programs into the clinic and bringing in the strategic investment from Astellas. He has been a valued partner that was foundational to furthering Taysha’s mission, and we wish him the best in his future endeavors.”

I look forward to working more closely with Dr. Suyash Prasad, and the entire Taysha clinical team to further the advancement of our lead programs in GAN and Rett syndrome.”
