ROCKVILLE, Md., Sept. 29, 2025 /PRNewswire/ -- REGENXBIO Inc. (NASDAQ: RGNX) today announced Chief Medical Officer, Steve Pakola, M.D., will present at the International Congress of the World Muscle Society taking place in Vienna, Austria, October 7-11, 2025.
The podium presentation will share new analysis of previously presented 12-month functional data from the Phase I/II trial of RGX-202, including individual patient improvement on the North Star Ambulatory Assessment (NSAA) using the established cTAP disease progression model from the Collaborative Trajectory Analysis Project. As reported, RGX-202 demonstrated a favorable safety profile with no serious adverse events or adverse events of special interest observed in the Phase I/II study. Pivotal dose participants exceeded baseline-matched external natural history controls on all functional measures.
Using multiple models of natural history disease progression, these results further demonstrate the potential of RGX-202 to serve as a differentiated, best-in-class gene therapy for the treatment of Duchenne muscular dystrophy.

About RGX-202
RGX-202 is a potential best-in-class investigational gene therapy designed for improved function and outcomes in Duchenne. RGX-202 is the only gene therapy approved or in late-stage development for Duchenne with a differentiated microdystrophin construct that encodes key regions of naturally occurring dystrophin, including the C-Terminal (CT) domain.
Additional design features such as codon optimization may potentially improve gene expression, increase protein translation efficiency and reduce immunogenicity. RGX-202 is designed to support the delivery and targeted expression of microdystrophin throughout skeletal and heart muscle using the NAV® AAV8 vector and a well-characterized muscle-specific promoter (Spc5-12). RGX-202 is manufactured by REGENXBIO using its proprietary, high-yielding NAVXpress® suspension-based platform process.
