    • ASCENTTM, a Phase III clinical trial conducted in partnership with AbbVie, is expected to enroll patients in the United States and Canada
    • Pivotal trials expected to support BLA submission for RGX-314 in 2024

    REGENXBIO Inc. (NASDAQ:RGNX) today announced the initiation of ASCENTTM, the second of two Phase III pivotal trials to evaluate the efficacy and safety of subretinal delivery of RGX-314 in patients with wet age-related macular degeneration (wet AMD). ASCENT, the first trial to be initiated by REGENXBIO under the eye care collaboration with AbbVie, is currently active and screening patients. RGX-314 is being investigated as a potential  one-time gene therapy for the treatment of wet AMD.

    A Biologics License Application (BLA) is expected to be submitted to the United States Food and Drug Administration (FDA) in 2024 based on two pivotal trials, ASCENT and the ongoing ATMOSPHERE trial.

    "The initiation of ASCENT is an important milestone for the pivotal program for subretinal delivery of RGX-314 in patients with wet AMD, and it is the first trial to be started under our partnership with AbbVie," said Steve Pakola, M.D., Chief Medical Officer of REGENXBIO. "ASCENT is designed similarly to our ongoing ATMOSPHERE trial, and key design elements for both pivotal studies are based on the positive long-term data from our dose-escalation Phase I/IIa trial of RGX-314. We look forward to advancing both trials to support our goal of a BLA filing in 2024."

    "The initiation of this Phase III study, a first under our collaboration with REGENXBIO, is an important advancement in our continued pursuit of innovative treatments for patients living with difficult-to-treat retinal diseases, visual impairment, and devastating vision loss," said Michael Robinson, MD, vice president, clinical development, ophthalmology, AbbVie. "We look forward to identifying the full potential of RGX-314 as part of our commitment to advancing vision care."

    ASCENT is a multi-center, randomized, active-controlled trial evaluating the efficacy and safety of subretinal delivery of RGX-314 across two dose arms, 6.4x1010 genomic copies per eye (GC/eye) and 1.3x1011 GC/eye, versus intravitreal injections of aflibercept, per label instructions. The primary endpoint of the trial is non-inferiority to aflibercept based on the change from baseline in Best Corrected Visual Acuity (BCVA) at one year. The trial will enroll approximately 465 patients across the two dose arms and the aflibercept control arm.

    About RGX-314

    REGENXBIO is investigating RGX-314 in collaboration with AbbVie as a potential one-time treatment for wet AMD, diabetic retinopathy, and other chronic retinal conditions. RGX-314 includes the NAV AAV8 vector containing a gene encoding for a monoclonal antibody fragment designed to inhibit vascular endothelial growth factor (VEGF). RGX-314 is believed to inhibit the VEGF pathway by which new, leaky blood vessels grow and contribute to the accumulation of fluid in the retina1.

    Two separate routes of administration of RGX-314 to the eye are being evaluated, including a standardized subretinal delivery procedure as well as delivery to the suprachoroidal space. REGENXBIO has licensed certain exclusive rights to the SCS Microinjector® from Clearside Biomedical, Inc. to deliver gene therapy treatments to the suprachoroidal space of the eye.

    About Wet AMD

    Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina2. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone3. Current anti-VEGF therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients4. These therapies, however, require life-long repeated intraocular injections to maintain efficacy5,6 and patients often experience a decline in vision with reduced frequency of treatment over time7.

    About ASCENT™

    ASCENT is a multi-center, randomized, active-controlled trial to evaluate the efficacy and safety of a single administration of RGX-314 versus standard of care in patients with wet AMD. The trial is designed to enroll 465 patients at a 1:1:1 ratio across two RGX-314 dose arms (6.4x1010 genomic copies per eye (GC/eye) and 1.3x1011 GC/eye delivered subretinally) and an active control arm of bi-monthly intravitreal injections of aflibercept (0.5 mg/eye), per label instructions. The primary endpoint of the trial is non-inferiority to aflibercept based on change from baseline in Best Corrected Visual Acuity (BCVA) at one year. Secondary endpoints of the trial include safety and tolerability, change in central retinal thickness (CRT) and need for supplemental anti-VEGF injections in the treatment arms. Patient selection criteria will include patients with wet AMD who are responsive to anti-VEGF treatment and will be independent of preexisting neutralizing antibody status. Patients will not receive prophylactic immune suppressive corticosteroid therapy before or after administration of RGX-314. The trial will be conducted at approximately 70 clinical sites across the United States and Canada. REGENXBIO and partner AbbVie are collaborating and sharing costs on this trial.

    • REGENXBIO expects to initiate trial in the first half of 2022

    REGENXBIO Inc. (NASDAQ:RGNX) today announced the clearance of its Investigational New Drug (IND) application by the United States Food and Drug Administration (FDA) to evaluate RGX-202, a potential one-time gene therapy for the treatment of Duchenne muscular dystrophy (Duchenne) in a first-in-human clinical trial. RGX-202 is designed to deliver a transgene for a novel microdystrophin that includes the functional elements of the C-Terminal (CT) domain found in naturally occurring dystrophin. RGX-202 uses REGENXBIO's proprietary NAV® AAV8 vector. REGENXBIO plans to initiate the trial in the first half of 2022.

    "We are excited to advance RGX-202, our investigational gene therapy for patients with Duchenne, into the clinic. Additional therapeutic options are still needed for the treatment of Duchenne, and our trial design follows compelling evidence from preclinical studies which demonstrated that one-time treatment with RGX-202 can express meaningful levels of a novel, functional microdystrophin protein in muscle, and showed significant improvements in muscle force and function in animal models," said Olivier Danos, Ph.D., Chief Scientific Officer of REGENXBIO. "This innovative AAV gene therapy candidate for Duchenne was developed in-house at REGENXBIO through a highly collaborative process between our expert research and manufacturing teams and we believe that RGX-202 can potentially address unmet needs for patients with Duchenne."

    AFFINITY DUCHENNETM Trial Design

    The Phase I/II trial, named AFFINITY DUCHENNE, is a multicenter, open-label dose escalation and dose expansion clinical study to evaluate the safety, tolerability and clinical efficacy of a one-time intravenous (IV) dose of RGX-202 in patients with Duchenne. In the dose escalation phase of the trial, six ambulatory, pediatric patients (ages 4 to 11 years old) with Duchenne are expected to enroll in two cohorts with doses of 1x1014 genome copies (GC)/kg body weight (n=3) and 2x1014 GC/kg body weight (n=3). After an independent safety data review for each cohort, a dose expansion phase of the trial may allow for up to six additional patients to be enrolled at each dose level (for a total of up to nine patients in each dose cohort).

    The trial design also consists of thorough safety measures informed by the Duchenne community and engagement with key opinion leaders, including a comprehensive, short-term, prophylactic immunosuppression regimen to proactively mitigate potential complement-mediated immunologic responses, and inclusion criteria based on dystrophin gene mutation status, including DMD gene mutations between exons 18 and 58. Trial endpoints include safety, immunogenicity assessments, pharmacodynamic and pharmacokinetic measures of RGX-202, including microdystrophin protein levels in muscle, and strength and functional assessments, including the North Star Ambulatory Assessment (NSAA) and timed function tests. Initial trial sites are expected to open in the U.S., with additional sites in Canada and Europe expected to follow.

    "I am proud of our scientific and medical teams' work with the Duchenne community resulting in a thoughtful and innovative clinical trial design, which we believe addresses a number of important factors, including safety considerations," said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO. "This trial will use material derived from our proprietary commercial-scale process which is expected to enable consistent clinical supply and support efficient transition to later stage development. We are working quickly to start dosing patients in this trial and look forward to continuing our important work with stakeholders across the Duchenne community."

    In support of the IND application, RGX-202 cGMP-grade material has been produced at commercial-scale capacity (1,000L) using REGENXBIO's proprietary suspension cell culture manufacturing process. REGENXBIO's internal cGMP facility is designed to enable production in 2,000L bioreactors and is on track to be fully operational in the first half of 2022. REGENXBIO plans to manufacture RGX-202 at the new facility. 

    About RGX-202

    RGX-202 is designed to deliver a transgene for a novel microdystrophin that includes the functional elements of the C-Terminal (CT) domain found in naturally occurring dystrophin. Presence of the CT domain has been shown in preclinical studies to recruit several key proteins to the muscle cell membrane, leading to improved muscle resistance to contraction-induced muscle damage in dystrophic mice. Additional design features, including codon optimization and reduction of CpG content, may potentially improve gene expression, increase translational efficiency and reduce immunogenicity. RGX-202 is designed to support the delivery and targeted expression of genes throughout skeletal and heart muscle using the NAV AAV8 vector, a vector used in numerous clinical trials, and a well-characterized muscle-specific promoter (Spc5-12).

    About Duchenne Muscular Dystrophy

    Duchenne muscular dystrophy (Duchenne) is a rare genetic disorder, caused by mutations in the gene responsible for making dystrophin, a protein of central importance for muscle cell structure and function. Duchenne primarily affects males with approximately 1 in 3,500 to 1 in 5,000 males affected worldwide. The absence of functional dystrophin protein in individuals with Duchenne results in cell damage during muscle contraction, leading to cell death, inflammation, and fibrosis in muscle tissues. Initial symptoms of Duchenne include muscle weakness that is often noticeable at an early age, with diagnosis typically occurring by 5 years of age. Over time, individuals with Duchenne experience progressive muscle weakness and eventually lose the ability to walk. Respiratory and heart muscles are also affected, leading to difficulty breathing and the need for ventilator assistance, along with the development of cardiomyopathy. There is presently no cure for Duchenne.

    REGENXBIO Inc. (NASDAQ:RGNX) today announced additional positive interim data from the ongoing Phase II AAVIATE® trial and the ongoing Phase II ALTITUDE™ trial of RGX-314 using in-office suprachoroidal delivery for the treatment of wet age-related macular degeneration (wet AMD) and diabetic retinopathy (DR) without center-involved diabetic macular edema (CI-DME), respectively. The results were presented at the American Academy of Ophthalmology (AAO) 2021 Annual Meeting by Robert L. Avery, M.D., Founder of California Retina Consultants and Research Foundation. 

    "We are pleased to share this initial data from Cohort 2 of the AAVIATE trial which provides encouraging evidence of the emerging clinical profile of RGX-314 for the treatment of wet AMD using suprachoroidal delivery. In the data reported today, RGX-314 was observed to be well tolerated in Cohort 2, with stable visual acuity and retinal thickness as well as a meaningful reduction in anti-VEGF treatment burden at six months," said Steve Pakola, M.D., Chief Medical Officer of REGENXBIO. "We look forward to providing additional updates from the program."

    "These initial results from patients in Cohort 2 of the AAVIATE trial at six months after suprachoroidal administration of RGX-314 reinforce the potential impact that RGX-314 could have on the overall clinical management of patients with wet AMD," said Dr. Avery. "I am encouraged by the six-month data in Cohort 2 and look forward to reviewing further data from Cohorts 1-3 and from the higher dose level in Cohorts 4 and 5."

    Study Design and Safety Update in Phase II AAVIATE Trial of RGX-314 for the Treatment of Wet AMD Using Suprachoroidal Delivery

    AAVIATE is a multi-center, open-label, randomized, active-controlled, dose-escalation trial that will evaluate the efficacy, safety and tolerability of suprachoroidal delivery of RGX-314 using the SCS Microinjector®. Twenty patients in Cohort 1 were randomized to receive RGX-314 at a dose level of 2.5x1011 genomic copies per eye (GC/eye) versus monthly 0.5 mg ranibizumab intravitreal injection at a 3:1 ratio. Twenty patients in Cohort 2 were randomized to receive RGX-314 at a dose level of 5x1011 GC/eye through two injections versus monthly 0.5 mg ranibizumab intravitreal injection at a 3:1 ratio. Cohort 3 is evaluating RGX-314 at the same dose level as Cohort 2 in 20 patients who are neutralizing antibody (NAb) positive. Enrollment is ongoing in two additional cohorts (Cohorts 4 and 5) to evaluate RGX-314 at a third dose level of 1x1012 GC/eye. Cohort 4 will enroll 15 patients who will be dosed with RGX-314 and Cohort 5 will evaluate the same dose level of RGX-314 in 20 patients who are NAb positive. Patients do not receive prophylactic immune suppressive corticosteroid therapy before or after administration of RGX-314.    

    As of November 4, 2021, RGX-314 was reported to be well tolerated across 50 patients dosed in Cohorts 1-3. Four serious adverse events (SAEs) were reported in four patients, all of which were considered not related to RGX-314.1  For the total group of Cohorts 1 and 2, all common treatment emergent adverse events (TEAEs) through 6 months in the study eye were mild, and included conjunctival hemorrhage, worsening of wet AMD, dry eye, episcleritis, and conjunctival hyperemia. Mild intraocular inflammation observed on slit-lamp examination was reported at similar incidence across both dose levels in Cohorts 1 and 2, with four out of 15 patients in Cohort 1 and three out of 15 patients in Cohort 2. All cases of inflammation in both cohorts were resolved within days to weeks on topical corticosteroids.

    Summary of Data for Cohort 2 in Phase II AAVIATE Trial of RGX-314 for the Treatment of Wet AMD at Six Months

    In Cohort 2, patients dosed with RGX-314 demonstrated stable Best Corrected Visual Acuity (BCVA) and central retinal thickness (CRT) at 6 months. Fifteen patients in Cohort 2 dosed with RGX-314 had a mean BCVA change of -0.1 letters (95% Confidence Interval: -3.8, 3.6) when measured from Day 1 (at Screening) and +0.2 letters (-2.7, 3.1) when measured from Week 1 (prior to Randomization). These patients also demonstrated stable central retinal thickness (CRT), with a mean change of -33 µm (-71, 5) at six months from Day 1. Ten control patients receiving monthly injections of ranibizumab in Cohorts 1 and 2 had a mean BCVA change at six months of +4.0 letters (-0.5, 8.5) when measured from Day 1 and +1.3 letters (-2.2, 4.8) when measured from Week 1. Patients receiving monthly injections of ranibizumab had a mean change of CRT of -12 µm (-33, 8) at six months from Day 1.

    There was a meaningful reduction in anti-vascular endothelial growth factor (anti-VEGF) treatment burden in patients following administration of RGX-314 compared to the mean annualized injection rate during the 12 months prior to administration. Patients in Cohort 2 received a mean of 1.3 injections over six months following administration of RGX-314, which represents a 71.8% reduction in anti-VEGF treatment burden. Six out of 15 patients (40%) in Cohort 2 received no anti-VEGF injections over six months following RGX-314 administration. In these patients, visual acuity and CRT was observed to be stable from Day 1 over six months, with a mean change of BCVA of +1.0 letters (-3.8, 5.8), and a mean change of CRT of +8 µm (-9.2, 24.2). 

    Summary of Visual Acuity Data for Cohort 1 in Phase II ALTITUDE Trial of RGX-314 for the Treatment of Diabetic Retinopathy at Three Months

    REGENXBIO shared additional data from Cohort 1 of the ongoing ALTITUDE trial for the treatment of DR without CI-DME using in-office suprachoroidal delivery, supporting the positive initial data previously reported at the American Society of Retina Specialists (ASRS) Annual Meeting in October 2021. At three months, 15 patients dosed with 2.5x1011 GC/eye of RGX-314 demonstrated stable BCVA of +2.6 letters, while five patients in the observational control arm demonstrated stable BCVA of -0.4 letters.

    About RGX-314

    RGX-314 is being investigated as a potential one-time treatment for wet AMD, diabetic retinopathy, and other chronic retinal conditions. RGX-314 consists of the NAV AAV8 vector, which encodes an antibody fragment designed to inhibit vascular endothelial growth factor (VEGF). RGX-314 is believed to inhibit the VEGF pathway by which new, leaky blood vessels grow and contribute to the accumulation of fluid in the retina.

    REGENXBIO is advancing research in two separate routes of administration of RGX-314 to the eye, through a standardized subretinal delivery procedure as well as delivery to the suprachoroidal space. REGENXBIO has licensed certain exclusive rights to the SCS Microinjector® from Clearside Biomedical, Inc. to deliver gene therapy treatments to the suprachoroidal space of the eye.

    About Wet AMD

    Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-VEGF therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients. These therapies, however, require life-long repeated intraocular injections to maintain efficacy. Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time.

    About Diabetic Retinopathy

    Diabetic retinopathy (DR) is the leading cause of vision loss in adults between 24 and 75 years of age worldwide. DR affects approximately eight million people in the United States alone. The spectrum of DR severity ranges from non-proliferative diabetic retinopathy (NPDR) to proliferative diabetic retinopathy (PDR) and as DR progresses, a large proportion of patients develop vision threatening complications, including diabetic macular edema (DME) and neovascularization that can lead to blindness.  Current treatment options for patients with DR include "watchful waiting", anti-VEGF treatment, retinal laser or surgical treatment.
