• Cash balance of approximately $1.1 billion as of December 31, 2024, with an additional $1.0 billion in upfront proceeds from PTC518 collaboration agreement with Novartis following closing.

  • Kebilidi^™ (eladocagene exuparvovec-tneq) gene therapy for AADC deficiency, approved in November 2024.

• In December 2024, PTC had a Type C meeting with FDA to discuss the potential for HTT lowering to serve as a surrogate endpoint to support accelerated approval for PTC518 for HD.
