Aflibercept

INCHEON, South Korea and CAMBRIDGE, MA, USA I November 18, 2024 I Samsung Bioepis Co., Ltd. and Biogen Inc. (Nasdaq: BIIB) today announced that the European Commission (EC) has approved OPUVIZ™ 40 mg/mL solution for injection in a vial, a biosimilar referencing Eylea 1,2 (aflibercept), developed and registered by Samsung Bioepis. OPUVIZ, also known as SB15, is approved in adult patients for the treatment of neovascular (wet) age related macular degeneration (AMD), visual impairment due to macular oedema secondary to retinal vein occlusion (RVO; branch or central RVO), visual impairment due to diabetic macular oedema (DME), and visual impairment due to myopic choroidal neovascularisation (myopic CNV). “Retinal disorders are affecting millions of people’s lives in Europe, yet many patients face barriers to treatment due to high costs,” said Byoungin Jung, Vice President, Regulatory Affairs at Samsung Bioepis. “The EC approval for OPUVIZ represents a major step toward our goal of expanding access to vital biologic therapies for those in need. We will continue working to expand access to our quality-assured, safe and effective biosimilars to improve patient’s quality of life and support sustainability of healthcare systems.” “This approval is an exciting milestone for both patients and healthcare systems in Europe. OPUVIZ has the potential to create a new treatment option for eligible patients, while also easing the burden of costs associated with these retinal conditions,” said Wolfram Schmidt, Head of Europe at Biogen. “We are delighted to continue our partnership with Samsung Bioepis, with the approval of our fifth biosimilar treatment option in Europe.” The EC approval was based on a totality of evidence including analytical, non-clinical data, and clinical data. A randomized, double-masked, parallel group, multicenter Phase 3 study demonstrated equivalent efficacy and comparable safety, immunogenicity, and pharmacokinetics (PK) profiles between SB15 and reference aflibercept (AFL). The primary endpoint was met in terms of change from baseline in best corrected visual acuity (BCVA) at week 8, and the 32-week interim analysis and 56-week analysis demonstrated comparability in other secondary efficacy, safety, immunogenicity, and PK endpoints between SB15 and AFL. 3, 4 OPUVIZ is the second ophthalmology biosimilar approved in Europe and fifth biosimilar in the portfolio developed by Samsung Bioepis with commercialization rights held by Biogen, which includes BYOOVIZ™ (ranibizumab), BENEPALI™ (etanercept), IMRALDI™ (adalimumab) and FLIXABI™ (infliximab). In November 2019, Samsung Bioepis and Biogen announced that they had entered into a commercialization agreement for two ophthalmology biosimilar candidates, BYOOVIZ (SB11, ranibizumab) and OPUVIZ (SB15, aflibercept), in the U.S., Canada, Europe and certain other markets. About the SB15 Phase 3 study 3,4 The study is a randomized, double-masked, parallel group phase 3 study conducted at 56 centers in 10 countries from June 2020 to March 2022, including follow-up through 56 weeks. Of 549 screened participants, 449 participants 50 years and older with treatment-naive nAMD were randomized 1:1 to receive either SB15 (n = 224) or AFL (n = 225). At Week 32, patients were re-randomized to either continue SB15 or AFL, or switch from AFL to SB15 resulting in three treatment groups; continuing SB15 (SB15/SB15, n=219), continuing AFL (AFL/AFL, n=108), switching from AFL to SB15 (AFL/SB15, n=111). In total, 425 patients completed up to Week 56. Key efficacy endpoints of the study were 1) change from baseline in best corrected visual acuity (BCVA), 2) change from baseline in central subfield thickness (CST), and 3) proportion of patients with intra or sub-retinal fluid.

(Nasdaq: ADVM), a clinical-stage company pioneering the use of gene therapy to preserve sight for life in highly prevalent ocular diseases, today announced topline 52-week results from the LUNA Phase 2 trial, new 4-year OPTIC long-term follow-up data and key pivotal program design elements. “We are thrilled to report 52-week LUNA data and 4-year OPTIC data that continue to support Ixo-vec as a transformative and potential best-in-class therapy, which may provide patients who have wet AMD with potentially life-long benefit and a predictable safety profile. Both OPTIC 2E11 results and LUNA efficacy data at 52 weeks show maintenance of visual and anatomic endpoints with over 80% reduction in injection burden and greater than 50% injection freedom. These consistent results are bolstered by our OPTIC long-term data where we have demonstrated stable therapeutic aflibercept levels through 5 years. The data across both studies support a reliable long-term benefit and a predictable safety profile,” stated Laurent Fischer, M.D., president and chief executive officer of Adverum Biotechnologies. “Ultimately, Ixo-vec is a potential paradigm-shifting solution for patients with wet AMD, where real-world evidence suggests that up to 57% of patients stop anti-VEGF treatment within 5 years, and the vast majority of patients end up losing vision. Designed as a single, one-time intravitreal injection, Ixo-vec has the potential to extend therapeutic benefit from weeks to years. Today’s 4-year OPTIC data suggest that Ixo-vec may preserve vision for the life of wet AMD patients.” “We have designed our Ixo-vec Phase 3 pivotal program to establish gene therapy as a standard of care for all wet AMD patients. Our ARTEMIS trial design considers feedback from key stakeholders, including global regulatory authorities, key opinion leaders, and patients, thereby optimizing for Ixo-vec’s potential clinical, regulatory and commercial success,” stated Rabia Gurses Ozden, MD, Chief Medical Officer at Adverum. “Today’s LUNA 52-week data support our decision to advance the 6E10 dose and topical-eyedrops-only prophylaxis into Phase 3. One of the unique, and in my view, profound aspects of this LUNA update was the near unanimous patient preference for Ixo-vec, as assessed via a pre-specified patient survey. The vast majority preferred Ixo-vec over their prior intravitreal injections. No patients on topical eyedrops alone stated that the steroid eyedrops were difficult to manage. And 100% of patients who received Ixo-vec 6E10 and eyedrops alone preferred Ixo-vec over prior anti-VEGF treatments.” “The LUNA 52-week clinical data further establish that the 6E10 dose of Ixo-vec has the potential to meaningfully reduce treatment burden for patients with wet AMD, even among patients with highly active disease who are receiving frequent dosing,” said Charles Wykoff, MD, PhD, Director of Research, Retina Consultants of Texas, Professor of Clinical Ophthalmology, Blanton Eye Institute, Houston Methodist Hospital and a principal investigator for LUNA. “Encouragingly, the 6E10 dose with extended prophylaxis also resulted in less inflammation. Taking these LUNA results together with 4-year data from the 2E11 dose in OPTIC, the totality of data indicates a predictable immune response with inflammation that, if it occurs, is manageable with local steroids, doesn’t impact vision, and ultimately resolves. These data from LUNA and OPTIC studies suggest a favorable benefit-risk profile for patients, which I believe many patients would consider if Ixo-vec were available in routine clinical practice. I look forward to working with the Adverum team as Ixo-vec advances toward pivotal studies next year.” LUNA Phase 2 Trial and OPTIC First-in-Human Trial - Background and Baseline Prior Anti-VEGF Injections LUNA is an ongoing double-masked, randomized Phase 2 trial. 60 patients with wet AMD were randomized equally across two dose cohorts, 6E10 or 2E11 vg/eye. The trial is evaluating multiple prophylactic regimens, including topical steroid eyedrops (difluprednate) with or without Ozurdex® and with or without oral steroids. LUNA is designed to inform the selection of both the Ixo-vec dose and prophylactic regimen for Phase 3 registrational trials. OPTIC is an ongoing, open-label, dose-ranging first-in-human trial. 30 patients with wet AMD requiring frequent IVT injections were enrolled equally across two doses, 2E11 or 6E11. Patients received either six weeks of prophylactic topical steroid eye drops or 13 days of prophylactic oral steroids. The OPTIC trial was a two-year study, with an optional 3-year extension. The LUNA and OPTIC data cutoff dates were August 29, 2024, and August 21, 2024, respectively. At the data cutoff date for LUNA, 57 patients had completed the 52-week study visit, with 3 discontinuations due to adverse events unrelated to study drug. 23 OPTIC patients elected to participate in the OPTIC extension. At the data cutoff date for OPTIC, 21 patients had completed the 4-year study visit, with 2 discontinuations unrelated to study drug. Both LUNA and OPTIC were designed to assess a broad wet AMD population, including hard-to-treat patients with severe disease who required frequent anti-VEGF injections before enrolling in the trial. At baseline, mean annualized prior anti-VEGF injections in the year prior to enrolling in LUNA and OPTIC were 10.1 (2.6 SD) and 9.9 (1.9 SD), respectively. LUNA 52-week Analysis Topline Data Summary Both doses of Ixo-vec maintained visual and anatomic endpoints through 52 weeks. Best Corrected Visual Acuity (BCVA) - least squares mean BCVA change from baseline at week 52 (95% CI)1: 6E10: -2.1 (-4.8, 0.7)2E11: -1.8 (-4.6, 0.9) 1. Excludes 1 participant at each dose with letter loss due to cataract Central Subfield Thickness (CST) - least squares mean CST (μm) change from baseline at week 52 (95% CI): 6E10: -10.2 (-29.0, 8.5)2E11: -21.9 (-40.4, -3.3) Both doses of Ixo-vec achieved an industry leading treatment burden reduction and proportion patients who were injection free through 52 weeks. Treatment Burden Reduction - % reduction in mean annualized anti-VEGF injections: 6E10: 88% treatment burden reduction2E11: 92% treatment burden reduction Proportion of Patients Injection Free: 6E10: 54% injection free, with 75% of patients with ≤1 injection2E11: 69% injection free, with 79% of patients with ≤1 injection Both doses of Ixo-vec were well tolerated, with local steroids effectively managing inflammation when present. No 6E10 patients had inflammation at week 52 or at any subsequent visit2.No Ixo-vec-related serious adverse events. All Ixo-vec-related AEs were either mild or moderate: no episcleritis, vasculitis, retinitis, choroiditis, vascular occlusion, or hypotony.The most common Ixo-vec-related AEs were dose-dependent anterior inflammation responsive to local corticosteroids and anterior pigmentary changes with no impact on vision.No new onset inflammation after week 30. 2. Inflammation defined as grade ≥ 1 AC/VC cells 6E10 dose with topical eyedrops as prophylactic regimen selected for pivotal program, providing a predictable long-term favorable safety profile. No patients at 6E10 with topical eyedrops had inflammation at week 52 or at any subsequent visit.Only one subject had inflammation, which resolved by year 1. LUNA results underscored by sub-group analyses that support potential best-in-class product profile and position Ixo-vec for potential clinical, regulatory and commercial success. Demonstrated consistent benefit in both patients with ≤300 μm baseline CST (“dry”) and patients with > 300 μm baseline CST (“wet”).Demonstrated maintenance of visual and anatomic outcomes in injection-free patients.Demonstrated even more robust clinical activity in patients with less treatment burden (experienced patients with <6 injections in year prior to LUNA). Results from our LUNA patient preference survey demonstrate strong preference for Ixo-vec over prior anti-VEGF therapies and acceptability of steroid regimen. 93% (n=56) of LUNA patients at 52 weeks prefer Ixo-vec, including accompanying steroid regimen, over prior treatments. Patient preference for Ixo-vec over prior treatments increased over time, from 88% (n=57) at 26 weeks.95% (n=56) of LUNA patients would elect to receive Ixo-vec in the other eye if both eyes had wet AMD.96% (n=56) of LUNA patients would recommend Ixo-vec to their family or friends with wet AMD.100% (n=10) of patients on the 6E10 pivotal dose and topical eyedrop steroid regimen prefer Ixo-vec over prior treatments for wet AMD.100% (n=10) of patients on the 6E10 pivotal dose and topical eyedrop steroid regimen would elect to receive Ixo-vec in other eye if both eyes had wet AMD.100% (n=10) of patients on the 6E10 pivotal dose and topical eyedrop steroid regimen would recommend Ixo-vec to their family or friends with wet AMD.No patients receiving topical eyedrop alone prophylaxis (n=20) stated it was difficult to manage. OPTIC (2E11) 4-year Analysis Topline Data Summary Patients in OPTIC received 9.9 mean annualized injections prior to receiving Ixo-vec. Despite significant treatment need at baseline, these patients continue to experience long-term benefit from Ixo-vec through at least 4 years of follow up, including maintenance of vision, durability of anatomical improvements and sustained reduction in anti-VEGF treatment burden. Aflibercept levels have been demonstrated up to 5-years post-treatment. Patients had an 86% reduction in annualized anti-VEGF injections through year 4, with a robust reduction in treatment burden demonstrated in each year following Ixo-vec administration. Through Year 1: 84% reduction in anti-VEGF injectionsThrough Year 2: 81% reduction in anti-VEGF injectionsThrough Year 3: 84% reduction in anti-VEGF injectionsThrough Year 4: 86% reduction in anti-VEGF injections 4-year OPTIC data underscore Ixo-vec’s reliable long-term benefit. Nearly 50% of patients were injection free through 4 years following Ixo-vec treatment.78% of OPTIC participants who were injection free through year 1 remained injection free through year 4.88% of OPTIC participants who were injection free through year 2 remained injection free through year 4.Durable aqueous aflibercept protein levels up to 5 years after a single Ixo-vec IVT injection. Ixo-vec at 2E11 was generally well tolerated and demonstrated a favorable safety profile. Inflammation was dose dependent, did not impact vision and, when present, was responsive to local corticosteroids.Long-term data establish a 10-fold safety margin from highest dose tested in nAMD. Key Design Elements of the Ixo-vec Phase 3 Pivotal Program The company plans to conduct two, double-masked, randomized Phase 3 clinical trials.The initial 284-patient, US-based ARTEMIS Phase 3 study is expected to enroll a broad patient population, including both treatment-naïve and treatment-experienced wet AMD patients.The primary endpoint, measured at an average of weeks 52 and 56, is non-inferiority (NI) in mean BCVA change from baseline between Ixo-vec (6E10 vg/eye) and aflibercept (2mg Q8W). The non-inferiority margin for this study is -4.5 letters.All patients will receive three monthly loading doses of aflibercept prior to Ixo-vec.The study will utilize a sham in the control arm to support masking. Patients in both arms will be eligible for supplemental injections of aflibercept and will receive topical steroid eye drops.This trial design is based on our end-of-Phase 2 feedback from the U.S. Food and Drug Administration (FDA).ARTEMIS remains on track and is expected to initiate in 1H 2025. Updated Cash Runway Guidance As of September 30, 2024, the company had $153.2 million in cash, cash equivalents and short-term investments. The company expects to be able to fund operations into the second half of 2025, which does not include completion of the ARTEMIS Phase 3 trial.

About Wet Age-Related Macular Degeneration Wet AMD, also known as neovascular AMD or nAMD, is a VEGF driven advanced form of AMD affecting approximately 10% of patients living with AMD associated with the build-up of fluid in the macula and the retina. Wet AMD is a leading cause of blindness in people over 65 years of age, with approximately 20 million individuals worldwide living with this condition. New cases of wet AMD are expected to grow significantly worldwide as populations age. AMD is expected to impact 288 million people worldwide by 2040, with wet AMD accounting for approximately 10% of those cases. Additionally, wet AMD is a bilateral disease, and incidence of nAMD in the second eye is up to 42% in the first two to three years. The current standard of care requires frequent life-long repeated bolus injections of anti-VEGF in the eye. IVT gene therapy has the promise to preserve vision and reduce most or all injections for the life of the patient by delivering stable therapeutic levels of anti-VEGF to control macular fluid. About Ixo-vec in Wet AMD Adverum is developing ixoberogene soroparvovec (Ixo-vec, formerly referred to as ADVM-022), its clinical-stage gene therapy product candidate, for the treatment of wet AMD. Ixo-vec utilizes a proprietary vector capsid, AAV.7m8, carrying an aflibercept coding sequence under the control of a proprietary expression cassette. Unlike other ophthalmic gene therapies that require surgery to administer the gene therapy under the retina (sub-retinal approach), Ixo-vec is designed to be administered as a one-time IVT injection in the physician’s office, deliver long-term efficacy, reduce the burden of frequent anti-VEGF, optimize patient compliance and improve vision outcomes for patients with wet AMD. In recognition of the need for new treatment options for wet AMD, FDA granted Fast Track designation for Ixo-vec for the treatment of wet AMD. Ixo-vec has also received PRIME designation from the EMA and the Innovation Passport from the United Kingdom’s Medicines and Healthcare Products Regulatory Agency for the treatment of wet AMD. About Adverum Biotechnologies Adverum Biotechnologies (NASDAQ: ADVM) is a clinical-stage company that aims to establish gene therapy as a new standard of care for highly prevalent ocular diseases with the aspiration of developing functional cures to restore vision and prevent blindness. Leveraging the capabilities of its proprietary intravitreal (IVT) platform, Adverum is developing durable, single-administration therapies, designed to be delivered in physicians’ offices, to eliminate the need for frequent ocular injections to treat these diseases. Adverum is evaluating its novel gene therapy candidate, ixoberogene soroparvovec (Ixo-vec, formerly referred to as ADVM-022), as a one-time, IVT injection for patients with neovascular or wet age-related macular degeneration. Additionally, by overcoming the challenges associated with current treatment paradigms for debilitating ocular diseases, Adverum aspires to transform the standard of care, preserve vision, and create a profound societal impact around the globe.
