FDA Should Demand Proof, Not Just Protein, for Duchenne

The FDA requires evidence that microdystrophin expression predicts clinical benefit, citing Pfizer's failed CIFFREO trial as a cautionary example. REGENXBIO reported 93% of patients reached 10% microdystrophin expression, but functional data is limited. The FDA seeks robust evidence before approval, given the permanent nature of gene therapy.
