(Nasdaq: RGNX) today announced financial results for the fourth quarter and full-year ended December 31, 2022, and recent operational highlights. "REGENXBIO enters the year with a strong pipeline of AAV Therapeutics. One year ago, we introduced our '5x'25' strategy and I remain confident that we will achieve this goal," said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO. "Our lead candidate, RGX-314, is being developed in partnership with AbbVie for the treatment of wet AMD and diabetic retinopathy, which present opportunities to make an impact in eye care for millions of patients. In 2022, we made meaningful progress with our RGX-314 trial enrollment objectives and geographic expansion planning. We also established in-house manufacturing to meet global clinical and commercial regulatory standards. We remain committed to developing treatments for rare diseases and made significant advancements with our pipeline of treatments for diseases such as Batten, Duchenne, Hurler and Hunter Syndrome, the latter of which we expect will support a second BLA filing using the accelerated approval pathway. Our history, science, resources, people and values combine to make us an industry leader in gene therapy and in the development of potentially ground-breaking therapies. We look forward to providing additional updates about our progress in 2023." Program Highlights and Milestones RGX-314: RGX-314 is an investigational one-time AAV Therapeutic being developed in collaboration with AbbVie for the treatment of wet age-related macular degeneration (wet AMD), diabetic retinopathy (DR) and other additional chronic retinal conditions. RGX-314 uses the NAV® AAV8 vector to deliver a gene encoding a therapeutic antibody fragment to inhibit vascular endothelial growth factor (VEGF). RGX-314 Subretinal Delivery for the Treatment of Wet AMD Enrollment is ongoing in ATMOSPHERE® and ASCENT™, two pivotal clinical trials to evaluate the efficacy and safety of RGX-314 in patients with wet AMD using the subretinal delivery approach. Material from REGENXBIO's NAVXpress™ platform process has been incorporated in the pivotal trials and is expected to be produced at REGENXBIO's Manufacturing Innovation Center for future commercialization of RGX-314. The pivotal trials are expected to support a Biologics License Application (BLA) submission in 2024. In February 2023, REGENXBIO announced data from the Phase II pharmacodynamic study, demonstrating that RGX-314 produced by the NAVXpress platform process was well tolerated and exhibited a similar clinical profile to the initial adherent cell culture process used in the Phase I/IIa trial. The Phase II pharmacodynamic study is designed to evaluate the same dose levels being used in the two pivotal trials. In October 2022, REGENXBIO announced data from the Phase I/IIa Long-term Follow-up study demonstrating that RGX-314 continued to be generally well-tolerated and showed a long-term, durable treatment effect in Cohort 3 up to four years and in Cohort 4 up to three years. Doses similar to those used in Cohort 3 and Cohort 4 of the Phase I/IIa trial were advanced into the pivotal trials. RGX-314 Suprachoroidal Delivery for the Treatment of Wet AMD The Phase II AAVIATE® trial continues to enroll patients in Cohort 6 at the third dose level with short-course prophylactic ocular steroids following RGX-314 administration to evaluate the ability to prevent or reduce the occurrence of the mild to moderate intraocular inflammation seen in previous cohorts. Patients are enrolled in Cohort 6 regardless of neutralizing antibody (NAb) status. REGENXBIO expects to complete enrollment of Cohort 6 in the first half of 2023 and report additional interim trial data, including initial data from Cohort 6, in the second half of 2023. In October 2022, REGENXBIO announced new interim data from the Phase II AAVIATE trial, demonstrating that RGX-314 using suprachoroidal delivery was well tolerated across 85 patients. Meaningful reduction in treatment burden at six months was observed across all dose levels, and no meaningful differences in outcomes were observed at six months for patients who are NAb positive. Some patients had mild to moderate intraocular inflammation, all of which resolved with topical corticosteroids. RGX-314 Suprachoroidal Delivery for the Treatment of DR The Phase II ALTITUDE® trial continues to enroll patients in two new cohorts at a higher third dose level, with patients stratified by Early Treatment Diabetic Retinopathy Study-Diabetic Retinopathy Severity Scale (DRSS) levels and all receiving short-course prophylactic ocular steroids following RGX-314 administration. REGENXBIO expects to complete enrollment of both cohorts from the higher third dose level in the first half of 2023 and report additional interim trial data, including initial data from the third dose level, in the second half of 2023. In November 2022, REGENXBIO announced new data from the Phase II ALTITUDE trial demonstrating that RGX-314 was well tolerated across 50 patients and BCVA remained stable through six months. Patients treated with RGX-314 demonstrated clinically meaningful improvements in disease severity and less disease worsening versus observation control at six months as measured by DRSS. No meaningful differences in safety outcomes were observed for patients who are NAb positive. Some patients had mild intraocular inflammation, all of which resolved with topical corticosteroids. RGX-202: RGX-202 is an investigational one-time AAV Therapeutic for the treatment of Duchenne Muscular Dystrophy (Duchenne), using the NAV AAV8 vector to deliver a transgene for a novel microdystrophin that includes the functional elements of the C-Terminal (CT) domain as well as a muscle specific promoter to support a targeted therapy for improved resistance to muscle damage associated with Duchenne. The Phase I/II AFFINITY DUCHENNE™ trial is active and recruiting patients. REGENXBIO plans to use commercial-scale cGMP material from the REGENXBIO Manufacturing Innovation Center in the clinical trial. REGENXBIO expects to report initial data from the trial in the second half of 2023. Additionally, REGENXBIO is recruiting patients in the AFFINITY BEYOND™ trial, an observational screening study to evaluate the prevalence of AAV8 antibodies in patients with Duchenne up to 12 years of age. Information collected in this study may be used to identify potential participants for the AFFINITY DUCHENNE trial and potential future trials of RGX-202. RGX-121: RGX-121 is an investigational one-time AAV Therapeutic for the treatment of Mucopolysaccharidosis Type II (MPS II), also known as Hunter Syndrome, using the NAV AAV9 vector to deliver the gene that encodes the iduronate-2-sulfatase (I2S) enzyme. The Phase I/II/III CAMPSIITE™ trial is ongoing, and is expected to incorporate material from the NAVXpress platform process manufactured at the REGENXBIO Manufacturing Innovation Center to support the future commercialization of RGX-121. CAMPSIITE is expected to complete enrollment of 10 MPS II patients in the first half of 2023 to support a BLA filing in 2024 using the accelerated approval pathway. In February 2023, REGENXBIO announced additional interim data from the Phase I/II part of the CAMPSIITE trial, demonstrating that RGX-121 continued to be well-tolerated across 15 patients. Patients receiving the pivotal program dose level continued to demonstrate the largest reductions in CSF GAGs and continued to approach normal levels at 48 weeks. CSF GAGs have the potential to be considered a surrogate biomarker that is reasonably likely to predict clinical benefit in MPS II disease under the accelerated approval pathway, as buildup of GAGs in the CSF of MPS II patients correlates with clinical manifestations, including neurodevelopmental deficits. Longer-term clinical measures demonstrated continued improvement in neurodevelopmental and daily activity skill acquisition up to three years after RGX-121 administration. A Phase I/II trial of RGX-121 for the treatment of pediatric patients with MPS II over the age of five years old is also ongoing. RGX-111: RGX-111 is an investigational one-time AAV Therapeutic for the treatment of severe Mucopolysaccharidosis Type I (MPS I), using the NAV AAV9 vector to deliver the α-l-iduronidase (IDUA) gene. A Phase I/II trial of RGX-111 for the treatment of MPS I is fully enrolled with follow-up ongoing. REGENXBIO is on track to manufacture commercial-scale cGMP material using the NAVXpress platform process in the first half of 2023 to support the continued development of RGX-111. REGENXBIO expects to share additional updates on program plans in the second half of 2023. In February 2023, REGENXBIO announced additional positive interim data from the Phase I/II trial demonstrating that RGX-111 was well tolerated in eight patients. Biomarker and neurodevelopmental assessments indicated an encouraging CNS profile in patients dosed with RGX-111. RGX-181: RGX-181 is an investigational one-time AAV Therapeutic for the treatment of late-infantile neuronal ceroid lipofuscinosis type 2 (CLN2) disease, a form of Batten disease, using the NAV AAV9 vector to deliver the TPP1 gene directly to the central nervous system. In December 2022, REGENXBIO announced that physician investigators in Brazil have dosed the first child with CLN2 disease with RGX-181 in a single-patient, investigator-initiated study. RGX-381: RGX-381 is an investigational one-time AAV Therapeutic for the treatment of the ocular manifestations of CLN2 disease using the NAV AAV9 vector to deliver the TPP1 gene directly to the retina. In December 2022, REGENXBIO announced a clinical trial application (CTA) has been accepted by the UK Health Authority to support a first-in-human, open-label, dose-escalation Phase I/II clinical trial to evaluate the safety and tolerability, as well as the effect on retinal anatomic and functional outcomes, of the subretinal delivery of RGX-381 for the treatment of ocular manifestations of CLN2 disease. REGENXBIO continues to expect to initiate the Phase I/II clinical trial in the first half of 2023. Operational Updates The REGENXBIO Manufacturing Innovation Center in Maryland is fully operational, producing GMP bulk substance lots to support programs using the NAVXpress™ platform process. The state-of-the-art cGMP gene therapy manufacturing facility is designed to meet global clinical and commercial regulatory standards and enable the Company to efficiently advance its AAV-based gene therapy pipeline from research and early development to clinical programs and commercial readiness. REGENXBIO is one of only a few gene therapy companies worldwide with a GMP facility capable of production at scales up to 2,000 liters. In 2023, REGENXBIO plans to utilize the facility to continue to produce commercial-scale cGMP material for its entire clinical pipeline and performance qualification lots to support planned BLA filings in 2024 for RGX-314 and RGX-121. NAV Technology Licensee Program Highlights As of December 31, 2022, REGENXBIO's NAV Technology Platform was being applied in one marketed product and multiple clinical stage partnered programs, with the potential to impact a broad range of therapeutic areas and disease indications. Zolgensma®, a one-time AAV Therapeutic for the treatment of spinal muscular atrophy (SMA), is a marketed product utilizing REGENXBIO's NAV AAV9 vector.
