- Trial Launch: REGENXBIO announced the dosing of the first patient in the Phase IIb/III NAAVIGATE clinical trial for diabetic retinopathy (DR), marking a significant milestone in its collaboration with AbbVie, which is expected to advance the clinical application of gene therapy.
- Funding Support: REGENXBIO will receive $100 million from AbbVie as a milestone payment, which not only strengthens the company's financial position but also provides funding for subsequent research, facilitating innovation in retinal disease treatment.
- Therapeutic Potential: Sura-vec, a one-time gene therapy, aims to improve long-term outcomes for DR patients by inhibiting vascular endothelial growth factor (VEGF), potentially transforming the current treatment paradigm that requires frequent interventions, thereby enhancing patient quality of life.
- Study Scale: The NAAVIGATE trial plans to enroll approximately 135 participants in the U.S. to primarily assess the safety and efficacy of sura-vec, and if successful, it will offer a new solution for DR treatment with significant market potential.

About RGNX
REGENXBIO Inc. is a clinical-stage biotechnology company seeking to improve lives through the curative potential of gene therapy. The Company has developed a pipeline of gene therapy programs using its proprietary adeno-associated virus (AAV) gene therapy delivery platform (NAV Technology Platform) to address an array of diseases. It is focused on its internal development pipeline in three areas: retinal, neuromuscular, and neurodegenerative diseases. Its investigational AAV therapeutics include ABBV-RGX-314, RGX-202, RGX-121, and RGX-111. It is developing ABBV-RGX-314 in collaboration with AbbVie to treat large patient populations impacted by wet age-related macular degeneration, diabetic retinopathy (DR) and other chronic retinal diseases characterized by loss of vision. It is developing RGX-202 to treat Duchenne muscular dystrophy (Duchenne). It is developing RGX-121 for the treatment of Mucopolysaccharidosis type II (MPS II), and RGX-111 to treat Mucopolysaccharidosis Type I.

REGENXBIO Initiates Phase IIb/III Trial for Diabetic Retinopathy
- Trial Initiation: REGENXBIO announced the dosing of the first patient in the Phase IIb/III NAAVIGATE clinical trial for diabetic retinopathy (DR), marking a significant milestone in its collaboration with AbbVie, which will yield a $100 million milestone payment, further advancing gene therapy clinical progress.
- Therapeutic Potential: Sura-vec demonstrated durable efficacy in the ALTITUDE trial with no intraocular inflammation observed in 15 patients, indicating its feasibility as a one-time treatment that could transform DR management and improve long-term visual outcomes for patients.
- Study Design: The NAAVIGATE trial aims to enroll approximately 135 participants in the U.S. to evaluate the safety and efficacy of sura-vec in non-proliferative DR patients without center-involved diabetic macular edema, with the primary endpoint being a greater than 2-step improvement on the diabetic retinopathy severity scale (DRSS) at one year.
- Future Outlook: REGENXBIO plans to present two-and-a-half-year data from the ALTITUDE trial at the 2026 ASRS Annual Meeting to further validate sura-vec's long-term efficacy, while also expecting to announce topline data from the ATMOSPHERE and ASCENT trials with AbbVie in Q4 2026, promoting its application in chronic retinal disease treatment.

FDA's Regulatory Reversal Boosts Biotech Sector
- Regulatory Impact: Under the leadership of new acting commissioner Kyle Diamantas, the FDA has rapidly reversed decisions made by former commissioner Marty Makary, particularly those affecting rare disease therapies, benefiting biotech firms like UniQure (QURE) and Regenxbio (RGNX) with significant stock price increases.
- Gene Therapy Opportunities: UniQure's AMT-130 gene therapy has received a regulatory path forward from the FDA after a reassessment, which previously faced uncertainty under Makary, paving the way for potential market application and future growth for the company.
- Accelerated Approval Outlook: Regenxbio's RGX-121 gene therapy saw a substantial stock surge after the FDA agreed to its accelerated approval plan, indicating strong support from the new leadership for rare disease treatments, which may attract more investor interest.
- Positive Market Reaction: Since Diamantas took over, biotech stocks, as represented by the SPDR S&P Biotech ETF, have surged approximately 15%, while the S&P 500 remained flat, reflecting market optimism about the new policies and potentially encouraging more biotech firms to seek regulatory support.
