Question
Dae Ha from SVB Leerink sought clarification on the AT132 patient numbers for the pivotal cohort versus prior guidance and asked about the clinical trial design for the DMD program, including the potential for a basket trial.
Answer
Chairman and CEO Matt Patterson clarified that the 8-patient pivotal expansion cohort for AT132 is a new, separate cohort, bringing the total BLA patient count to 22. For the DMD program, he stated that Audentes will file its own IND in Q1 for its optimized construct and that the company is creatively exploring a basket trial approach for subsequent exon-skipping programs.
