Ethan Markowski's questions to Taysha Gene Therapies Inc (TSHA) leadership • Q2 2025
Question
Ethan Markowski from Needham & Company questioned if Taysha expects any FDA pushback on using a six-month interim readout for a BLA filing, especially given a competitor's recent regulatory feedback.
Answer
CEO Sean Nolan stated that Taysha's interim analysis approach is highly data-driven, supported by robust Part A data showing a clear and significant effect at six months, with an 83% responder rate in the high-dose group. He confirmed that discussions with the FDA have been constructive and are focused on refining the analysis details, with no pushback received on the viability of the six-month interim itself.
