• Translarna™ (ataluren) total net product revenue was $77 million, with growth coming from new patients in existing geographies and continued geographic expansion
• Emflaza^® (deflazacort) total net product revenue was $55 million, driven by new patient starts, broader access, continued high compliance and appropriate weight-based dosing

Key Clinical and Regulatory Updates:

• PTC submitted a meeting request to the FDA to gain clarity on the regulatory pathway for the NDA for Translarna in the US. While the FDA has provided initial written feedback that Study 041 does not provide substantial evidence of effectiveness, PTC is planning follow up discussions with the agency to understand whether the evidence in the ITT population in Study 041 along with confirmatory evidence from other studies could support approval.
• PTC held a type C meeting with the FDA to discuss the details of a potential submission package for Upstaza.

PTC is currently working with the FDA to address this request and expects to submit a BLA for Upstaza in the first half of 2023.

• Enrollment in the PIVOT-HD Phase 2 trial of PTC518 for Huntington's disease is active and ongoing at study sites in Europe and Australia.
