ABBV-RGX-314: We are developing ABBV-RGX-314 (surabgene lomparvovec) in collaboration with AbbVie as a potential one-time treatment for chronic retinal conditions that cause total or partial vision loss, including wet age-related macular degeneration (wet AMD) and diabetic retinopathy (DR). ABBV-RGX-314 is currently being evaluated in multiple clinical trials, including two pivotal trials (ATMOSPHERE and ASCENT), one Phase II bridging study, one long-term follow-up study and a fellow eye sub-study in patients with wet AMD, all utilizing subretinal delivery. Additionally, two Phase II clinical trials in patients with wet AMD (AAVIATE) and DR (ALTITUDE) are ongoing along with two corresponding long-term follow-up studies, all utilizing in-office suprachoroidal delivery. Within the Phase II study in DR, we are also evaluating ABBV-RGX-314 in diabetic macular edema (DME). ABBV-RGX-314 uses the NAV® AAV8 vector to deliver a gene encoding a therapeutic antibody fragment to inhibit vascular endothelial growth factor (VEGF). We have licensed certain exclusive rights to the SCS Microinjector® from Clearside Biomedical, Inc. (Clearside) to deliver gene therapy treatments to the suprachoroidal space of the eye.

Previous wording

The AAVIATE® trial is a multi-center, open label, randomized, controlled, dose-escalation Phase II trial to evaluate the efficacy, safety and tolerability of suprachoroidal delivery of ABBV-RGX-314 for the treatment of wet AMD. As of July 29, 2024, ABBV-RGX-314 at dose level 3 with short course prophylactic steroid eye drops continues to be well tolerated with no drug-related serious adverse events (SAEs) and no cases of intraocular inflammation, endophthalmitis, vasculitis, retinal artery occlusion, choroidal effusion or hypotony. Mild episcleritis occurred in three patients, all resolved and completed treatment with topical steroids. There were no cases of elevated intraocular pressure. Based on this favorable safety profile, the Phase II AAVIATE trial is initiating enrollment in a new cohort to evaluate ABBV-RGX-314 at dose level 4 (1.5x10e12 GC/eye). Patients in this cohort will also receive short course prophylactic steroid eye drops.

These data included positive biomarker data from the first nine patients, which demonstrated consistent, robust microdystrophin and transduction, as well as positive initial functional data. In March 2025, we presented additional positive Phase I/II biomarker data, including the first biomarker data from the cohort of patients aged 1-3, at the 2025 Muscular Dystrophy Association Clinical & Scientific Conference.

Current wording

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, which is expected to enroll approximately 30 patients in the U.S. and Canada, as well as positive interim safety and efficacy data from the Phase I/II portion of the study were announced in November 2024. These data included positive biomarker data from the first nine patients, which demonstrated consistent, robust microdystrophin and transduction, as well as positive initial functional data. Subsequent findings were presented in March 2025 at the 2025 Muscular Dystrophy Association Clinical & Scientific Conference and in June 2025 via a Company webcast. In sum, these data were positive and demonstrate potential for RGX-202 to serve as a differentiated gene therapy for Duchenne. As of May 2025, we had reported positive microdystrophin data on 12 patients and positive initial functional data from five patients. We also reported a favorable safety profile with no serious adverse events or adverse events of special interest observed (n=13).

In February 2024, we announced that, 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 FDA approval of RGX-121 in the second half of 2025.
