Detailed Narrative
RGX202 Duchenne Program Advances Towards BLA Submission
REGENXBIO completed enrollment and dosing in the confirmatory study for RGX202 ahead of schedule, building a robust safety data set of over 60 patients for the planned BLA filing. The pivotal data showed a strong correlation between microdystrophin expression and functional improvement at one year, supporting potential accelerated approval. The company plans to initiate a global randomized placebo-controlled study (Affinity Rise) outside the U.S. in H1 2027 and submit the first module of the BLA to the FDA in Q3 2026, targeting potential U.S. approval in H2 2027.
RGX121 MPS II Program Aligns with FDA for Resubmission
Following collaborative discussions and a Type A meeting with the FDA in June and July, REGENXBIO reached alignment on the path forward for RGX121. The FDA confirmed that available data is sufficient for review under the accelerated approval pathway, requiring no additional studies, including an RCT. The BLA resubmission, expected in Q3 2026, will include longer-term efficacy and safety data, including up to two-year biomarker and neurocog data.
Retinal Franchise Progress with AbbVie Collaboration
The strategic collaboration with AbbVie continues to advance the retinal franchise. The first patient was dosed in the Phase 2b-3 NAVIGATE study for diabetic retinopathy, triggering a $100 million milestone payment. Long-term data for Cirovec in both wet AMD and diabetic retinopathy, presented at ASRS, highlighted durable safety and efficacy. The near-term focus is on the upcoming pivotal readout for Cirovec in subretinal wet AMD from the Atmosphere and Ascent Studies in Q4 2026.
Strengthened Financial Position and Extended Cash Runway
REGENXBIO substantially strengthened its financial position, receiving over $200 million in total new capital. This includes the $100 million milestone payment from AbbVie and approximately $108 million in net proceeds from a follow-on public offering. The company ended the quarter pro forma with over $310 million in cash, cash equivalents, and marketable securities, extending its cash runway into Q4 2027, which covers key milestones like the Cirovec wet AMD data and the expected PDUFA date for RGX202.
Commercial Readiness and Global Expansion Plans
The strengthened cash position supports continued investment in strategic priorities, including preparing for the U.S. commercial launch of RGX202. The company is also manufacturing intended commercial supply at its FDA-inspected facility. Plans are underway to expand the clinical development of RGX202 globally with the XUS Affinity Rise study, a randomized placebo-controlled trial designed to support future regulatory submissions outside the U.S.
