Recent Operational Highlights

Gene Therapy Using NAV^® Vectors for AAV-Mediated Antibody Delivery

• Pivotal Program for RGX-314 for the Treatment of Wet Age-related Macular Degeneration (wet AMD)
• REGENXBIO announced in January 2021 that it completed an End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA) to discuss the details of a pivotal program to support a Biologics License Application (BLA). REGENXBIO plans to conduct two randomized, well-controlled clinical trials to evaluate the efficacy and safety of RGX-314 in patients with wet AMD, enrolling approximately 700 patients total. REGENXBIO expects to submit a BLA based on these trials in 2024.
• ATMOSPHERE™, the first of two planned pivotal trials, is active and enrolling patients. The trial will enroll approximately 300 patients across two RGX-314 dose arms versus ranibizumab. The primary endpoint of the trial is non-inferiority to ranibizumab based on change from baseline in Best Corrected Visual Acuity (BCVA) at one year.
• The second pivotal trial is expected to be similar in design to ATMOSPHERE and REGENXBIO plans to initiate the trial in the second half of 2021.
• The Company plans to incorporate its scalable suspension cell culture manufacturing process to support future commercialization upon completion of a bridging study and the pivotal trials. The bridging study is expected to initiate in the first half of 2021.
• In February 2021, REGENXBIO presented additional positive data from the patients enrolled in the ongoing Phase I/II trial of RGX-314 for the treatment of wet AMD and its Long-Term Follow-Up study.
• As of January 22, 2021, RGX-314 continued to be generally well-tolerated across all dose cohorts.
• Durable treatment effect was observed in patients in Cohorts 4 and 5 at 1.5 years after administration of RGX-314, including stable visual acuity, decreased retinal thickness, and reductions in anti-VEGF injection burden.
• Long-term, durable treatment effect was demonstrated in Cohort 3 over three years, including mean improvement in vision and stable retinal thickness, and reductions in anti-VEGF treatment burden.
  
  
• Suprachoroidal Delivery of RGX-314 for the Treatment of Wet AMD
• In January 2021, REGENXBIO announced that it had completed enrollment of patients in Cohort 1 of AAVIATE™, a Phase II trial for the treatment of wet AMD. The Company plans to report interim efficacy data from Cohort 1 in the third quarter of 2021. Enrollment of patients in Cohort 2 has begun and is expected to be complete in the second quarter of 2021.
  
  
• Suprachoroidal Delivery of RGX-314 for the Treatment of Diabetic Retinopathy (DR)

• As of January 4, 2021, RGX-121 is reported to be well-tolerated with no drug-related serious adverse events (SAEs) in eight patients dosed with RGX-121.
• Biomarker data from patients in both cohorts indicate encouraging signals of I2S enzyme activity in the CNS following one-time administration of RGX-121, with consistent reductions of HS and D2S6, a component of HS. Patients in Cohorts 1 and 2 also demonstrated continued neurocognitive development and evidence of I2S enzyme activity in plasma and urine following administration of RGX-121.

Marketed NAV Technology Products

REGENXBIO's NAV Technology Platform is being applied in one marketed product, Zolgensma^®. On January 26, 2021, Novartis AG reported fourth quarter 2020 global Zolgensma sales revenue of $254 million and full year 2020 revenue of $920 million.  

In December 2020, REGENXBIO entered into an agreement to monetize a portion of the royalty rights due from the net sales of Zolgensma to entities managed by Healthcare Royalty Management, LLC (HCR) for gross proceeds of $200 million.

Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $522.5 million as of December 31, 2020, compared to $400.0 million as of December 31, 2019. The increase was primarily attributable to gross proceeds of $200.0 million received from the monetization of REGENXBIO's Zolgensma royalty rights, partially offset by net cash used in operating activities of $54.1 million and cash used to purchase property and equipment of $26.9 million in 2020.

Revenues: Revenues were $21.4 million and $154.6 million for the three months and year ended December 31, 2020, respectively, compared to $11.8 million and $35.2 million for the three months and year ended December 31, 2019, respectively. The increases were primarily attributable to Zolgensma royalty revenue, which increased by $10.2 million and $40.8 million for the three months and year ended December 31, 2020, respectively, as compared to the same periods in 2019. The increase in revenue for the year ended December 31, 2020 also includes an $80.0 million milestone fee recognized as revenue in the third quarter of 2020 upon the achievement of $1.0 billion in cumulative net sales of Zolgensma. As reported by Novartis AG, sales of Zolgensma for the fourth quarter of 2020 increased by 37% (USD) as compared to the fourth quarter of 2019.

Research and Development Expenses: Research and development expenses were $47.2 million and $166.3 million for the three months and year ended December 31, 2020, respectively, compared to $33.8 million and $124.2 million for the three months and year ended December 31, 2019, respectively. The increases were primarily attributable to personnel costs as a result of increased headcount and expenses associated with manufacturing services and conducting clinical trials for our lead product candidates.

General and Administrative Expenses: General and administrative expenses were $17.6 million and $63.8 million for the three months and year ended December 31, 2020, respectively, compared to $14.5 million and $51.8 million for the three months and year ended December 31, 2019, respectively. The increases were primarily attributable to personnel costs as a result of increased headcount and professional fees for advisory and other services.

Net Loss: Net loss was $46.2 million, or $1.24 basic and diluted net loss per share, and $111.3 million, or $2.98 basic and diluted net loss per share, for the three months and year ended December 31, 2020, respectively, compared to net loss of $26.5 million, or $0.72 basic and diluted net loss per share, and $94.7 million, or $2.58 basic and diluted net loss per share, for the three months and year ended December 31, 2019, respectively.

On January 12, 2021, REGENXBIO announced the closing of an underwritten public offering of 4,260,000 shares of its common stock at a price to the public of $47.00 per share, as well as the exercise in full of the underwriters' option to purchase 639,000 additional shares at the public offering price. Including the option exercise, the total gross proceeds received by REGENXBIO from the offering were approximately $230.3 million, before deducting the underwriting discounts and commissions and other offering expenses.

Financial Guidance

Based on its current operating plan, REGENXBIO expects its balance in cash, cash equivalents and marketable securities of $522.5 million as of December 31, 2020, as well as the $230.3 million of gross proceeds received from its public offering of common stock completed in January 2021, to fund its operations, including the completion of its internal manufacturing capabilities and clinical advancement of its product candidates, into the second half of 2023.
