“I am excited to join Kyverna at this pivotal time and help advance the organization into its next critical phase of growth,” said Mr. Pujols. “The Company has demonstrated remarkable progress in advancing miv-cel towards registration and establishing first-in-class leadership in autoimmune CAR T. I look forward to working with the team to further accelerate our technical operations to support the launch of the Company’s transformative therapies for patients living with autoimmune diseases.”
