Adverum Biotechnologies, Inc. Announces Data Presentations at the ARVO and ASGCT 2017 Annual Meetings

MENLO PARK, Calif., May 10, 2017 -- Adverum Biotechnologies, Inc. (Nasdaq:ADVM), a leading gene therapy company advancing novel medicines to address unmet needs in serious rare and ocular diseases, today announced preclinical data on the Company’s next-generation vectors are being presented today at the Association for Research in Vision and Ophthalmology (ARVO) and American Society of Gene & Cell Therapy (ASGCT) 2017 annual meetings.

“These presentations highlight the work underway to leverage our industry-leading capabilities in novel vector development,” said Amber Salzman, Ph.D., president and chief executive officer of Adverum Biotechnologies. “Discovered from our AAV-based directed evolution and rational design platform, these next-generation gene therapy vectors are designed to improve transduction in target tissues, ocular and systemic, and overcome the effects of neutralizing antibodies seen with conventional vectors. We are very excited about the preclinical data presented at ARVO on one of our novel variants, expanding our arsenal of vectors capable of transducing the retina via intravitreal injection.”
