Adverum Biotechnologies Announces Upcoming Data Presentation at AAO 2022

REDWOOD CITY, Calif., Sept. 23, 2022 (GLOBE NEWSWIRE) — Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage company that aims to establish gene therapy as a new standard of care for highly prevalent ocular diseases, today announced that data from the OPTIC trial of ixoberogene soroparvovec (Ixo-vec, formerly referred to as ADVM-022) in wet age-related macular degeneration (wet AMD) will be presented next week during the Late Breaking Developments portion of Retinal Subspecialty Day at the American Academy of Ophthalmology (AAO) 2022 Annual Meeting in Chicago, Illinois. In addition to reviewing the durable efficacy and safety demonstrated out to 104 weeks in the OPTIC Study, the presentation will include new analyses of intraretinal fluid (IRF) and subretinal fluid (SRF) after a single, in-office, intravitreal (IVT) injection of Ixo-vec in subjects requiring frequent anti-VEGF injections for their wet AMD. Oral Presentation Title: ADVM-022 Intravitreal Gene Therapy for Neovascular AMD: OPTIC Phase 1 Study UpdateSession: Late Breaking Developments, Part IDate & Time: September 30, 2022, 3:39 PM – 3:44 PM EDTPresenter: Dante Pieramici, M.D., partner, California Retina Consultants Adverum intends to issue a press release concurrent with the presentation and to post the data presented on the Publications page in the Pipeline section of the company’s website. About Wet Age-Related Macular Degeneration Wet AMD, also known as neovascular AMD or nAMD, is an advanced form of AMD, affecting approximately 10% of patients living with AMD. Wet AMD is a leading cause of blindness in patients over 65 years of age, with a prevalence of approximately 20 million individuals worldwide living with this condition. The incidence of new cases of wet AMD is expected to grow significantly worldwide as populations age. AMD is projected to impact 288 million people worldwide by 2040, with wet AMD accounting for approximately 10% of those cases. About OPTIC Trial of ADVM-022 in Wet AMD ADVM-022, ixoberogene soroparvovec (Ixo-vec), is Adverum’s clinical-stage gene therapy product candidate being developed for the treatment of wet AMD. ADVM-022 (Ixo-vec) utilizes a propriety vector capsid, AAV.7m8, carrying an aflibercept coding sequence under the control of a proprietary expression cassette. Unlike other ophthalmic gene therapies that require a surgery to administer the gene therapy under the retina (sub-retinal approach) ADVM-022 has the advantage of being administered as a one-time IVT injection in the office and is designed to deliver long-term efficacy and reduce the burden of frequent anti-VEGF injections, optimize patient compliance, and improve vision outcomes for patients with wet AMD. The OPTIC trial is designed as a multi-center, open-label, dose-ranging, safety and efficacy trial of ADVM-022 (Ixo-vec) in participants with wet AMD who have demonstrated responsiveness to anti-VEGF treatment. Patients in OPTIC are treatment experienced, and previously required frequent anti-VEGF injections to manage their wet AMD and to maintain functional vision. 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 research 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. By overcoming the challenges associated with current treatment paradigms for these debilitating ocular diseases, Adverum aspires to transform the standard of care, preserve vision, and create a profound societal impact around the globe.
