REDWOOD CITY, Calif., May 06, 2021 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases, today reported financial results for the first quarter ended March 31, 2021.

“Our management team and Board are focused on conducting a thorough review of patient safety data from the ADVM-022 program to inform our next steps,” said Laurent Fischer, M.D., chief executive officer at Adverum Biotechnologies. “At ARVO last weekend, long-term data from the OPTIC trial were presented, demonstrating ADVM-022’s durability in patients with treatment-experienced neovascular or wet age-related macular degeneration. As part of our broader mission to advance the field of gene therapy, we are committed to the work our team is doing on behalf of patients who need new treatment options for ocular diseases.”

Recent Developments

• On April 28, 2021, Adverum announced a Suspected Unexpected Serious Adverse Reaction (SUSAR) of hypotony (clinically-relevant decrease in ocular pressure), with panuveitis and loss of vision in the treated eye, in its INFINITY clinical trial evaluating ADVM-022 for the treatment of diabetic patients with macular edema. The company has unmasked the study and is assessing and monitoring this patient and all patients treated with ADVM-022 and is working closely with investigators, the data monitoring committee (DMC), the scientific advisory board, and healthcare authorities. The patient impacted by the SUSAR event is undergoing in-person assessments with leading retina specialists across the U.S. who are working with Adverum to gain an understanding of the causes of the SUSAR and to develop a treatment plan for the patient. In addition, all patients who have received ADVM-022 have been requested to see their treating physician for an evaluation, including ophthalmic and advanced imaging assessments to collect additional data. Adverum, working with its expert advisors, is conducting a thorough review of data from the ADVM-022 program, taking into account learnings from the SUSAR, and plans to report its findings as the analysis progresses.
• At ARVO in May 2021, long-term OPTIC clinical data were presented (March 10, 2021 cutoff date, n=30) that continue to demonstrate the potential of ADVM-022 to greatly reduce the anti-VEGF injection burden for patients with wet AMD. All ADVM-022-related ocular adverse events (AE) were mild (80%) to moderate (20%) in OPTIC patients with wet AMD. No clinical or fluorescein evidence of posterior inflammation and no vasculitis, retinitis, choroiditis, vascular occlusions, or endophthalmitis were observed. The OPTIC data presentation is available on the Publications section of Adverum’s website.
• In light of the announced SUSAR, the company is evaluating its timelines and capital allocation priorities with an aim to extend its cash runway beyond prior guidance.

Financial Results for the Three Months Ended March 31, 2021

• Cash, cash equivalents and short-term investments were $404.0 million as of March 31, 2021, compared to $429.7 million as of December 31, 2020.
• License revenue was $7.5 million for the three months ended March 31, 2021, compared to no revenue for the same period in 2020. License revenue for the three months ended March 31, 2021 was due to an upfront payment received on a license agreement.
• Research and development expenses were $20.0 million for the three months ended March 31, 2021, compared to $14.8 million for the same period in 2020. Research and development expenses increased primarily due to higher personnel-associated costs, material production costs, and clinical trial expenses. Stock-based compensation expense included in research and development expenses was $2.3 million for the first quarter of 2021.
• General and administrative expenses were $16.2 million for the three months ended March 31, 2021, compared to $9.0 million for the same period in 2020. General and administrative expenses increased primarily due to higher personnel-associated costs, professional services costs, and depreciation expense for Adverum’s Redwood City facility. Stock-based compensation expense included in general and administrative expenses was $4.9 million for the first quarter of 2021.
• Net loss was $28.4 million, or $0.29 per basic and diluted share, for the three months ended March 31, 2021, compared to $22.9 million, or $0.31 per basic and diluted share, for the same period in 2020.
