In July 2024, the Company announced the submission of an NDA to the FDA for sepiapterin for the treatment of pediatric and adult patients with PKU, including the full spectrum of ages and disease subtypes. Pursuant to the Censa Merger Agreement, the decision to submit the NDA triggered a $25.0 million regulatory milestone to the former Censa securityholders. The $25.0 million regulatory milestone will be recorded in research and development expense for the three and nine months ended September 30, 2024.
