REDWOOD CITY, Calif., Nov. 05, 2020 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases, today reported recent business progress and financial results for the third quarter ended September 30, 2020.

“We are continuing execution and progress across our organization as preparations are underway for us to become a late-stage gene therapy company next year with two programs underway for ADVM-022, in wet AMD and DME,” said Laurent Fischer, M.D., chief executive officer of Adverum. “We believe that ADVM-022 has the potential to reduce the treatment burden for the millions of patients living worldwide with these chronic ocular diseases with a potential “one and done” treatment. The FDA’s recent removal of the partial clinical hold is an important milestone achievement as we intend to initiate our pivotal trial for ADVM-022 in wet AMD in mid-2021. Based on the positive data from OPTIC in wet AMD and the progress with INFINITY in DME, we are preparing to meet with regulators to discuss our development plans for ADVM-022 in order to accelerate our development, manufacturing, and future commercial launch plans for this therapy. We continue to expand our team of leaders as we establish world-class capabilities across operational functions to plan for future opportunities to deliver novel gene therapies to patients.”

Recent Progress

• Adverum has received notification that the U.S. Food and Drug Administration (FDA) has removed the partial clinical hold on ADVM-022 after the company provided the agency with the requested information related to CMC. The partial hold did not affect the INFINITY Phase 2 trial for DME or current doses evaluated in the OPTIC Phase 1 trial for wet AMD. Adverum plans to meet with the agency to discuss the company’s plans for pivotal trials to support the filing of a Biologics License Application (BLA) for ADVM-022 in wet AMD.
• Adverum raised approximately $203.4 million in net proceeds from an underwritten public offering in August 2020.
• Thomas Kochy joined Adverum as vice president, commercial and program strategy. Mr. Kochy has program leadership, product marketing, and sales management expertise, including 10 years of experience in Genentech’s Ophthalmology franchise.
• Christopher J. Morrison, Ph.D. joined Adverum as vice president, process science. Dr. Morrison has 10 years of pharmaceutical industry experience and has a background in gene therapy, recombinant adeno-associated viral vector (rAAV) process development, and clinical manufacturing.
