REDWOOD CITY, Calif., Feb. 02, 2021 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc.(Nasdaq: ADVM), a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases, today announced the publication of preclinical data on ADVM-022 intravitreal (IVT) gene therapy in Translational Vision Science & Technology (TVST), an official journal of the Association for Research in Vision and Ophthalmology (ARVO). ADVM-022 is in clinical trials for wet AMD and DME, and this preclinical study in NHPs is the longest safety and expression study to date, with measurements out 30 months following a single IVT injection.

There is a growing body of both clinical and preclinical data demonstrating durable efficacy and favorable safety profile following a single IVT injection of ADVM-022, said Laurent Fischer, M.D., chief executive officer at Adverum Biotechnologies. In this preclinical study, we saw long-term, sustained aflibercept expression out to 30 months following ADVM-022. The levels of aflibercept were sustained at therapeutic levels, with no measurable adverse effects on normal retinal structure and function. We are excited to work on developing ADVM-022 as a potential one and done IVT injection therapy that may dramatically reduce the treatment burden for patients living with wet AMD and DME.

Szilrd Kiss, M.D., academic retina specialist, added, Currently, patients with wet AMD are treated with frequent anti-VEGF intravitreal injections to maintain their vision. One of the highest priorities in research today is to develop therapies that extend the duration of efficacy following treatment, enabling patients to preserve sight for months or years following treatment. The preclinical data on ADVM-022 demonstrate long-term safety and aflibercept expression following a single intravitreal injection of this novel IVT injection gene therapy. We are excited to continue to assess ADVM-022 as it demonstrates the potential to improve real-world visual outcomes over intermittent anti-VEGF injections for patients living with wet AMD.

The publication, titled Long-Term Safety Evaluation of Continuous Intraocular Delivery of Aflibercept by the Intravitreal Gene Therapy Candidate ADVM-022 in Nonhuman Primates, reported the following:

About ADVM-022 Gene TherapyADVM-022 utilizes a propriety vector capsid, AAV.7m8, carrying an aflibercept coding sequence under the control of a proprietary expression cassette. ADVM-022 is administered as a one-time intravitreal injection (IVT), 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 age-related macular degeneration (wet AMD) and diabetic macular edema (DME).

In recognition of the need for new treatment options for wet AMD, the U.S. Food and Drug Administration granted Fast Track designation for ADVM-022 for the treatment of wet AMD.

Adverum is currently evaluating ADVM-022 in the OPTIC Phase 1 clinical trial in patients with wet AMD and the INFINITY Phase 2 trial in patients with DME at 2 x 10^11 vg/eye and 6 x 10^11 vg/eye doses. The Company plans to begin a pivotal trial in mid-2021 for ADVM-022 in wet AMD.

About Adverum BiotechnologiesAdverum Biotechnologies (Nasdaq: ADVM) is a clinical-stage gene therapy company targeting unmet medical needs in serious ocular and rare diseases. Adverum is advancing the clinical development of its novel gene therapy candidate, ADVM-022, as a one-time, intravitreal injection for the treatment of patients with wet age-related macular degeneration and diabetic macular edema.
