Eric Schmidt's questions to Agios Pharmaceuticals Inc (AGIO) leadership •
Question
Eric Schmidt from Cantor Fitzgerald asked for scientific insights gained from the Oxbryta withdrawal, particularly concerning its mechanism of action compared to mitapivat, and how this might affect the probability of success for the RISE UP study.
Answer
CMO Dr. Sarah Gheuens emphasized that mitapivat has a very different mechanism of action, working to reduce 2,3-DPG and increase ATP to address both hemolysis and sickling. She contrasted this with Oxbryta's mechanism and pointed to mitapivat's robust, placebo-controlled Phase II data as strong support for its distinct and promising profile.
