RGNX announced that it has completed dosing in its confirmatory study of RGX-

202 ahead of schedule (the company had previously guided to dosing completion

by mid-year), which the company attributes to patient demand and investigator

interest. Plans for a BLA filing under the accelerated approval pathway also remain

on-track, with a rolling submission expected to begin in 3Q26 with completion in

1Q27. Recall, RGNX recently reported topline results from the pivotal portion of

AFFINITY DUCHENNE (see here) that showed a correlation between
