Joon Lee's questions to PTC Therapeutics Inc (PTCT) leadership • Q2 2025
Question
Joon Lee of Truist Securities asked if a potential CBER decision on an accelerated approval path for a Huntington's gene therapy could set a regulatory precedent for CBER's review of PTC's oral drug. He also asked for clarification on whether PTC still owes royalties to Sarepta.
Answer
CEO Dr. Matthew Klein acknowledged watching the CBER review with interest, noting that positive read-throughs are possible and that regulatory agencies increasingly desire alignment between divisions like CBER and CBER on rare diseases. He expressed confidence in PTC's own data package for accelerated approval. CFO Pierre Gravier confirmed that PTC still owes a low single-digit royalty to Sarepta.
