Adverum Biotechnologies Presents Research Pipeline Data Supporting Utility of its Proprietary Platform and AAV.7m8 Capsid in Ocular Gene Therapy

REDWOOD CITY, Calif., May 19, 2022 (GLOBE NEWSWIRE) — Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases, today will announce new research pipeline data supporting the utility of its proprietary adeno-associated virus (AAV) vector platform in ocular gene therapy. These new data will be featured in oral presentations during the American Society of Gene and Cell Therapy (ASGCT) 2022 Annual Meeting in Washington, D.C. and virtually.

“Adverum is an industry leader in the development of adeno-associated virus ocular gene therapy, including cassette engineering and vectorizing therapeutic proteins, and we are pleased to have multiple presentations highlighting our platform at ASGCT. As we continue to prepare for the initiation of a Phase 2 trial of ADVM-022 for wet AMD in the third quarter of 2022, we are also advancing other research programs toward the clinic and expanding our pipeline in ocular gene therapy by building on the potential of a single in-office intravitreal injection with our proprietary AAV.7m8 capsid,” said Brigit Riley, Ph.D., chief scientific officer at Adverum Biotechnologies. “We are excited to present non-clinical data on ADVM-062 (AAV.7m8-L-opsin) for blue cone monochromacy, which received Orphan Drug Designation by the U.S. Food and Drug Administration in January 2022, and continue to advance this program toward an investigational new drug application submission. Adverum continues the technical advances of our in-house adeno-associated virus manufacturing processes. Finally, we are maturing a portfolio of proprietary vectors with specific ocular cell tropism and are excited to showcase our innovative work on LSV1, a novel capsid for ocular gene therapy.”

ADVM-062 for Blue Cone Monochromacy (BCM) Data Highlights

  • ADVM-062 was well tolerated at all doses tested
  • No observed adverse effect level for the study was 3×10^11 vg/eye dose in non-human primate (NHP)

LSV1 Data Highlights

  • Identified LSV1 from a library screen in NHP
  • LSV1 has a unique 3D structure at the 3-fold axis imparting new structural characteristics from parental backbone
  • LSV1 efficiently transduces NHP retina from the vitreous
  • High expression in the fovea and periphery, as well as retinal pigment epithelium expression

About Blue Cone Monochromacy

BCM is an X-linked recessive hereditary condition caused by the absence of function in the L and the M opsin genes and can manifest in loss of visual acuity, photosensitivity, myopia and infantile nystagmus that can persist into adulthood. Consequently, individuals with BCM have visual impairments to important aspects of daily living such as facial recognition, learning, reading, and daylight vision. Currently, BCM affects approximately 1 to 9 in 100,000 males, worldwide and there is no cure for BCM.

About ADVM-062 Gene Therapy

ADVM-062 (AAV.7m8-L-opsin) is a novel gene therapy product candidate being developed to deliver a functional copy of the OPN1LW gene to the foveal cones of patients suffering from blue cone monochromacy (BCM) via a single IVT injection. ADVM-062 utilizes Adverum’s propriety vector capsid, AAV.7m8. In January 2022, the FDA granted Orphan Drug Designation to ADVM-062.
