Jack Padovano's questions to Regenxbio Inc (RGNX) leadership • Q2 2025
Question
Jack Padovano, on for Annabel, questioned the rationale for adding a fourth dose level to the Suravec trial, asking if the one-year efficacy data from dose level three was already considered sufficient for approval or if further improvement was needed to convince the FDA.
Answer
President & CEO Curran Simpson confirmed the latter, stating that while dose level three results are considered sufficient and meet the target product profile, dose level four presents an opportunity to achieve even better efficacy. CMO Dr. Steve Pakola added that the one-year effect size is acceptable from a benefit-risk standpoint, and the key is that it translates into preventing vision-threatening events, which has been observed.
