ROCKVILLE, Md., May 14, 2026 /PRNewswire/ -- REGENXBIO Inc. (Nasdaq: RGNX) today reported financial results and operational highlights for the first quarter ended March 31, 2026.
"REGENXBIO enters a transformative year with positive momentum, reaching significant late-stage milestones to support our potential first- and best-in-class gene therapies," said Curran Simpson, President and Chief Executive Officer, REGENXBIO. "On our mission to bring meaningful new therapies to rare disease communities facing limited options, we remain focused on advancing RGX-202 for Duchenne toward potential BLA submission and are excited to share topline pivotal data in our webcast today; we also continue engaging with the FDA regarding a potential path forward for RGX-121 for Hunter syndrome. In chronic retinal diseases, we are executing against our multi-indication strategy and preparing for the Phase 3 wet AMD readout with partner AbbVie. Additionally, we continue harnessing internal manufacturing capabilities to support anticipated commercial needs. We remain well-positioned to capitalize on several near-term, high-value opportunities and bring these highly differentiated treatments to patients."
PROGRAM HIGHLIGHTS AND MILESTONES
Neuromuscular Disease: RGX-202 is a potential best-in-class gene therapy for Duchenne muscular dystrophy (Duchenne). RGX-202 is designed to address the underlying cause of Duchenne by enabling targeted expression of a novel microdystrophin that is closest to naturally occurring dystrophin. It is the only microdystrophin that includes the C-Terminal domain, which has been shown to protect and preserve muscle function. The differentiated therapeutic approach behind RGX-202 includes a novel construct, a proactive immune suppression regimen, and a suspension-based manufacturing process that delivers industry-leading product purity levels. RGX-202 is designed for improved muscle function, durability and positive safety outcomes and is being evaluated in the Phase I/II/III AFFINITY DUCHENNE® trial in ambulatory patients aged 1+.
- REGENXBIO today announced positive topline results from the pivotal Phase III AFFINITY DUCHENNE trial of RGX-202, including primary endpoint (n=30 at Week 12), interim safety (n=31), and interim functional data (n=9 at 12 months):[1]
- Achieved primary endpoint with high statistical significance; 93% of patients achieved RGX-202 microdystrophin expression above 10% (p<0.0001)
- RGX-202 was well-tolerated, continued to demonstrate a favorable interim safety profile.
- Statistically significant correlation between RGX-202 microdystrophin expression level and functional improvement (NSAA, n=9), supporting the validity of the surrogate endpoint.
- More than 20 additional participants have been enrolled in the confirmatory trial of RGX-202 (n=30), and the Company expects to have completed dosing in all 60 patients across the pivotal and confirmatory trials by mid-year.
- REGENXBIO continues to manufacture intended commercial supply of RGX-202 at its in-house Manufacturing Innovation Center.
- Topline data supports plans for potential accelerated approval in 2027.

1 30 of 31 total participants have Week 12 biopsy available for evaluation; one participant refused muscle biopsy. |
Retinal Disease: Surabgene lomparvovec (sura-vec, ABBV-RGX-314), developed in collaboration with AbbVie, is potentially the first-in-class gene therapy treatment for wet age-related macular degeneration (wet AMD) and diabetic retinopathy (DR).
Sura-vec for the Treatment of Wet AMD (Subretinal Delivery)
- REGENXBIO expects to share topline data with AbbVie from ATMOSPHERE® and ASCENT® pivotal trials of sura-vec using subretinal delivery in Q4 2026.
- Global regulatory submissions are expected in 2027.
Sura-vec for the Treatment of DR (Suprachoroidal Delivery)
- U.S. clinical sites are active and initiating enrollment in the Phase IIb/III NAAVIGATE study. NAAVIGATE is a Phase IIb/III multicenter, randomized, masked, sham-controlled study to evaluate the safety and efficacy of sura-vec in subjects with non-proliferative DR (NPDR) without center-involved diabetic macular edema (CI-DME).
- REGENXBIO will receive a $100 million milestone payment from AbbVie upon first patient dosed in the Phase IIb portion of NAAVIGATE, expected in Q2 2026.
Sura-vec for the Treatment of Wet AMD (Suprachoroidal Delivery)
- Enrollment is complete in the Phase II AAVIATE® trial.
Neurodegenerative Disease: Clemidsogene lanparvovec (RGX-121) is a potential first-in-class treatment for Mucopolysaccharidosis (MPS) Type II, also known as Hunter syndrome. RGX-111 is an investigational one-time treatment for severe MPS I, also known as Hurler syndrome. These programs are partnered with Nippon Shinyaku.
- The FDA has lifted the partial clinical hold on RGX-121.
- REGENXBIO recently filed an appeal of the 121 CRL and is continuing to engage the agency regarding a path forward for the program.
FINANCIAL RESULTS
Cash Position: Cash, cash equivalents and marketable securities were $150.5 million as of March 31, 2026, compared to $240.9 million as of December 31, 2025. The decrease was primarily driven by cash used to fund operating activities during the first quarter of 2026. Cash used in operations in the first quarter of 2026 included a non-recurring payment of $10.0 million under a previously announced settlement agreement with GlaxoSmithKline in March 2026, and is otherwise generally consistent with historical first quarter cash spend.
Revenues: Revenues were $6.4 million for the three months ended March 31, 2026, compared to $89.0 million for the three months ended March 31, 2025. The decrease was primarily attributable to $70.0 million of upfront license recognized under the collaboration with Nippon Shinyaku in the first quarter of 2025, as well as a $12.2 million decrease in ZOLGENSMA® royalty revenues due to the expiration of licensed patents in the U.S. in January 2026. Novartis launched U.S. sales of ITVISMA® in the first quarter of 2026. REGENXBIO is entitled to royalties on certain net sales of ITVISMA in the U.S. and other jurisdictions with patents extending until 2037.
Research and Development (R&D) Expenses: R&D expenses were $57.3 million for the three months ended March 31, 2026 compared to $53.1 million for the three months ended March 31, 2025. The increase was primarily attributable to clinical trial expenses for RGX-202 and personnel-related costs.
General and Administrative Expenses: General and administrative expenses were $21.3 million for the three months ended March 31, 2026 compared to $20.3 million for the three months ended March 31, 2025. The increase was largely driven by personnel-related costs, consulting and corporate advisory services.
Net Income: Net loss was $90.1 million, or $1.72 basic and diluted net loss per share, for the three months ended March 31, 2026, compared to net income of $6.1 million, or $0.12 basic and diluted net income per share, for the three months ended March 31, 2025.
FINANCIAL GUIDANCE
REGENXBIO expects its balance in cash, cash equivalents and marketable securities of $150.5 million as of March 31, 2026 to fund its operations into early 2027. This cash runway guidance is based on the Company's current operational plans and excludes the impact of any material payments that may potentially be received from partners or licensees upon the achievement of development or regulatory milestones, or upon the approval or commercialization of product candidates, and excludes any additional potential dilutive or non-dilutive funding opportunities.
CONFERENCE CALL
REGENXBIO will host a conference call and webcast at 8:00 a.m. ET today to discuss the RGX-202 topline data as well as first quarter 2026 updates. The live webcast can be accessed here and in the Investor section of REGENXBIO's website at www.regenxbio.com. An archived replay of the webcast will be available for approximately 30 days following the presentation.
