DR and DME
Current report
The ALTITUDE trial is now enrolling a new cohort of patients with center-involved DME. DME is a vision-threatening complication of DR; an estimated 34 million people globally have DME. Patients will receive a one-time, in-office injection of ABBV-RGX-314 at dose level 4 (1.5x10e12 GC/eye) with short course prophylactic steroid eye drops.
Current report
AFFINITY DUCHENNE® is a multicenter, open-label Phase I/II/III trial to evaluate the safety, tolerability and clinical efficacy of a one-time intravenous dose of RGX-202 in patients with Duchenne aged one and older. The initiation of the pivotal study as well as positive safety and efficacy data from the Phase I/II portion of the study, including the first functional data, were announced in November 2024. In March 2025, we announced that the pivotal study was nearly 50% enrolled, and we expect to complete enrollment in the study in 2025, share top line data in the first half of 2026 and submit a Biologics License Application (BLA) under the accelerated approval pathway in mid-2026.
Current report
We expect to share additional Phase I/II biomarker data at the 2025 Muscular Dystrophy Association (MDA) Clinical & Scientific Conference, including the first biomarker data from the cohort of patients aged 1-3. The company expects to share additional efficacy and safety data, including additional functional data, in the first half of 2025.
Current report
In the pivotal phase of the Phase I/II/III CAMPSIITE® trial, RGX-121 achieved its primary endpoint, a reduction in cerebrospinal fluid Heparan sulfate levels of D2S6, a biomarker indicative of brain disease activity, with statistical significance. In September 2024, we announced positive data from the pivotal dose level of RGX-121 demonstrating long-term systemic effect. We plan to use levels of cerebrospinal fluid Heparan sulfate D2S6 as a surrogate endpoint reasonably likely to predict clinical benefit for accelerated approval. A BLA for RGX-121 seeking accelerated approval was submitted to the FDA in March 2025, which we believe is likely to be eligible for priority review. We expect potential approval of RGX-121 in the second half of 2025.
Current report
RGX-111: We are developing RGX-111 in collaboration with Nippon Shinyaku in the United States and certain countries in Asia as an investigational one-time AAV therapeutic for the treatment of Mucopolysaccharidosis Type I (MPS I), also known as Hurler syndrome, using the NAV AAV9 vector to deliver the IDUA gene.
Current report
In November 2023, future development of RGX-111 was halted as a result of a strategic pipeline prioritization and corporate restructuring. Prior to that announcement, RGX-111 was demonstrated to be well tolerated and indicated encouraging biomarker and neurodevelopmental results in a Phase I/II study. Efforts to continue development of RGX-111 are set to be reinitiated following our announcement in January 2025 of a strategic partnership with Nippon Shinyaku.

Previous report
AFFINITY DUCHENNE™ is a multicenter, open-label dose evaluation and dose expansion clinical trial to evaluate the safety, tolerability and clinical efficacy of a one-time intravenous (IV) dose of RGX-202 in patients with Duchenne. In February 2024, we reported interim data from the trial, demonstrating that RGX-202 continued to be well tolerated with no drug-related serious adverse events in five patients at dose levels 1 and 2. Initial biomarker data in three patients who completed three-month assessments indicate encouraging increases in expression of RGX-202 microdystrophin and reduction from baseline in serum creatinine kinase levels, supporting evidence of clinical improvement. We expect to make a pivotal dose determination in mid-2024. We expect to share initial strength and functional assessment data for both dose levels and the initiation of a pivotal trial in the second half of 2024. We plan to use RGX-202 microdystrophin expression as a surrogate endpoint to support a Biologics License Application (BLA) filing using the accelerated approval pathway.

License and royalty revenue
Previous report
Cost of Revenues. Cost of revenues decreased by $17.3 million, from $54.5 million for the year ended December 31, 2022 to $37.2 million for the year ended December 31, 2023. The decrease was largely attributable to a non-recurring charge of $9.2 million recognized in the first quarter of 2022 related to the amendment of our license agreement with The Trustees of the University of Pennsylvania (Penn) to buy out our obligation to pay sublicense fees to Penn under the license agreement. The remaining decrease in cost of revenues was primarily attributable to a reduction in upstream royalties payable to licensors on net sales of Zolgensma during the period.
Previous report
The decrease in research and development expenses for ABBV-RGX-314 was largely driven by a shift in the development cost sharing arrangement under our collaboration with AbbVie beginning in 2023. In accordance with the AbbVie Collaboration Agreement, through December 31, 2022 we were responsible for development expenses related to certain ongoing clinical trials of ABBV-RGX-314 and the remaining ABBV-RGX-314 development expenses were shared with AbbVie. Beginning in 2023, AbbVie became responsible for the majority of all ABBV-RGX-314 development expenses.
Previous report
Other Operating Expenses (Income). Other operating expenses were $0.4 million for the year ended December 31, 2023, as compared to other operating income of $6.7 million for the year ended December 31, 2022. The change was primarily attributable to proceeds of $7.5 million received under a settlement agreement with a third party in the fourth quarter of 2022 that released certain claims regarding infringement of the Company's intellectual property.
Previous report
Interest Expense. Interest expense decreased by $16.4 million, from $23.3 million for the year ended December 31, 2022 to $6.9 million for the year ended December 31, 2023. The decrease was primarily attributable to a lower balance in our liability related to the sale of future royalties resulting from Zolgensma royalties paid to HCR, as well as changes in the effective interest rate of the liability resulting from changes in the estimated royalties forecasted to be paid to HCR over the life of the royalty purchase agreement.

Many of these factors are outside of our control. Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory and marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our product revenues, if any, and any commercial milestones or royalty payments under our licensing agreements, will be derived from or based on sales of products that may not be commercially available for many years, if at all. In addition, revenue from our NAV Technology Platform licensing is dependent in part on the clinical and commercial success of our licensing partners, including the commercialization of Zolgensma, and on maintaining our license agreements with our licensor partners, including GlaxoSmithKline LLC (GSK) and Penn. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives.

This includes certain personnel in executive, commercial, corporate development, finance, legal, human resources, information technology, facilities and administrative support functions. Additionally, general and administrative expenses include facility-related and overhead costs not otherwise allocated to research and development expense, professional fees for accounting, legal, commercial and other advisory services, expenses associated with obtaining and maintaining patents, insurance costs, costs of our information systems and other general corporate activities. We expect that our general and administrative expenses will continue to increase as we continue to develop, and potentially commercialize, our product candidates.

We intend to devote the majority of our current capital to preclinical research, clinical development, seeking regulatory approval of our product candidates and, if approved, commercialization of our product candidates, as well as additional capital expenditures needed to support these activities. Because of the numerous risks and uncertainties associated with the development and commercialization of gene therapy product candidates, we are unable to estimate the total amount of operating expenditures and capital outlays necessary to complete the development of our product candidates. While we expect the pipeline prioritization and corporate restructuring implemented in November 2023 to result in cost savings, we may also incur other charges or cash expenditures not currently contemplated due to events that may occur as a result of, or associated with, the restructuring. In addition, we may not achieve the expected benefits of any cost reduction measures on our currently anticipated timeline, or at all. Furthermore, our estimates are based on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect which could accelerate our liquidity needs.
