Key Financial Performance

Cash, cash equivalents, and marketable securities $364 million as of June 30, 2025, compared to $245 million as of December 31, 2024. This increase was primarily driven by the $110 million upfront payment from Nippon Shinyaku in Q1 2025 and $145 million in net proceeds from the royalty monetization with HealthCare Royalty Partners in Q2 2025, partially offset by cash used for operating activities.

R&D expenses $60 million for Q2 2025, compared to $49 million for Q2 2024. The increase was primarily attributed to manufacturing-related expenses, clinical supply costs, and clinical trial expenses for sura-vec and RGX-202 pivotal trials.

Risk or Challenges

Regulatory and Product Development Risks: The company acknowledges that forward-looking statements regarding financial outlook, regulatory, and product development plans are subject to risks and uncertainties. These include potential delays or failures in regulatory approvals, such as the FDA decision for RGX-121, which could impact commercialization timelines.

Manufacturing and Supply Chain Risks: The company is initiating commercial manufacturing for RGX-202, but any disruptions or inefficiencies in the manufacturing process could delay product availability. Additionally, the reliance on in-house manufacturing capabilities for large-scale production poses operational risks.

Clinical Trial Risks: Ongoing pivotal trials for RGX-202, sura-vec, and other programs are critical to the company's strategy. Delays in enrollment, adverse safety events, or failure to meet efficacy endpoints could jeopardize regulatory approvals and market entry.

Financial Risks: The company’s cash runway is projected to last until early 2027, but this is contingent on achieving milestones and securing non-dilutive financing. Failure to meet these milestones or delays in financing could strain financial resources.

Market and Competitive Risks: The company faces competitive pressures in the gene therapy market, particularly for Duchenne and retinal diseases. Failure to establish a strong market position or differentiate its products could limit revenue potential.

Safety and Efficacy Risks: While the company has reported favorable safety profiles for its therapies, any unforeseen adverse events in ongoing or future trials could impact regulatory approvals and market acceptance.

Key Q&A

Q:What is the reaction from the DMD community regarding the conditioning or prophylaxis regimen in 202?

A:The DMD community's interest in the program is at an all-time high. The proactive immune suppression regimen has greater appeal due to safety concerns with high-dose AAV treatments. Patients appreciate the level of monitoring and surveillance, which brings them comfort. The company is conducting webinars and expanding study sites to increase awareness and enrollment.

Q:What are the thoughts on the improvement in DRSS between year 1 and year 2 in dose level 3 for DR?

A:The improvement is attributed to sustained anti-VEGF activity and potential disease modification. The single injection shows durable benefits in DRSS imaging improvement and prevents vision-threatening complications. The data has excited both the company and AbbVie, leading to a pivot in the pivotal design to ensure no efficacy is left on the table.

Q:Why is dose level 4 being added to the pivotal study Phase IIb for DR?

A:Dose level 4 is being added due to the improvement seen in dose level 3 and the good safety profile. The company wants to ensure no efficacy is left on the table and to evaluate the potential for further improvement with a higher dose. The primary endpoint for the pivotal study is at 1 year.

Q:What is the rationale for the milestone amendment change with AbbVie?

A:The original contract did not contemplate a Phase IIb study. AbbVie updated the amendment to recognize the IIb and initiate part of the milestone payment earlier, which helps with cash runway. The $200 million milestone remains intact, split into two $100 million payments, with the first $100 million covering the Phase IIb study costs.

Q:What is the strategy for the DMD launch regarding the prevalent patient population versus those ineligible for existing therapies?

A:The company sees an opportunity for a broad label, recruiting patients aged one and older. They aim to take a dominant market position with a differentiated product showing strong functional benefits and a favorable safety profile. The focus is currently on the ambulatory study, with potential future exploration of the non-ambulatory population.

Q:What is the potential strategy for non-ambulatory DMD patients?

A:The company has not had detailed discussions with the FDA about a non-ambulatory study design but plans to do so after expanding the safety database in the ambulatory population. They are taking a cautious approach and focusing on establishing a good safety profile in the ambulatory population first.

Q:What are the expectations for the subretinal Phase III for wet AMD?

A:The primary endpoint is safety and noninferiority on VA, with secondary endpoints focusing on injection burden reduction. A 50% reduction in injection burden is considered clinically meaningful. The company believes the sustained anti-VEGF activity will benefit vision maintenance and reduce treatment burden.

Q:What is the potential path to approval for diabetic retinopathy (DR)?

A:Two adequate and well-controlled studies are required. The Phase IIb/III study will serve as one of these studies, with plans to start the second pivotal study immediately after the interim readout of the first. The studies will be double-masked with a sham injection as the control.

Q:What is the current view on the market dynamic at launch for 202?

A:The company estimates that greater than 90% of the prevalent population will still be available at launch due to interruptions in the launch of existing therapies. They plan to stockpile significant doses to address the market demand and aim to take a significant portion of the market at launch.

Q:Will there be a class effect for liver injury applied to the label for 202?

A:The company believes each program should be evaluated individually. Their differentiated approach, including high product purity and proactive immune modulation, has shown no signs of liver injury in their Phase I/II study, which sets them apart from existing therapies with higher liver injury rates.

Q:What is the rationale for the Phase IIb with 314?

A:The decision to include dose level 4 is to explore the potential for improved efficacy, even though dose level 3 already meets the target product profile. The company and AbbVie are confident in the 1-year endpoint and believe the data will provide confidence to the clinical community.

Q:What is the design of the Phase IIb/III study for DR?

A:The Phase IIb/III study is structured to roll into a Phase III after an interim readout. The study will be double-masked with a sham injection as the control. The company plans to start the second pivotal study immediately after the interim readout of the first.

Q:What is the company's approach to the FDA amidst leadership changes?

A:The company is in constant contact with the FDA review teams and has not detected any significant shifts in study design requirements. They plan to continue enrollment and expand the safety database, with the option to adjust if needed. The pivotal protocol was reviewed by a consistent review team, providing confidence in the process.

Q:What is the dosing difference between subretinal and suprachoroidal delivery for wet AMD?

A:The doses for subretinal delivery are lower than those for suprachoroidal delivery. The suprachoroidal route allows for higher doses due to its targeted local delivery and good safety profile. The company has shown efficacy and safety with bilateral dosing in the suprachoroidal route.

Q:Review of Unclear Management Responses

A:Management avoided providing specific details on the cost of the Phase IIb study, stating only that the $100 million milestone payment would more than cover the costs. Additionally, they did not provide a detailed breakdown of the prevalent patient population for DMD or specific pricing strategies for the wet AMD product amidst Medicare reimbursement changes.
