Adverum Reports Second Quarter 2021 Results

REDWOOD CITY, Calif., Aug. 05, 2021 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc. ADVM, a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases, today reported financial results for the second quarter ended June 30, 2021.

"Adverum has an experienced team and is well capitalized to execute our current plans to prioritize the development of ADVM-022 in wet age-related macular degeneration," said Laurent Fischer, M.D., president and chief executive officer at Adverum Biotechnologies. "Based on our current focus and timelines, we are able to extend our cash runway into 2024. The long-term data from OPTIC in patients with wet AMD show the potential for the low dose of ADVM-022 to offer durable, disease-modifying treatment following a single, in-office intravitreal injection. The current standard of care for wet AMD requires frequent anti-VEGF injections in the eye, which are a burden for patients, caregivers, and healthcare systems and make access challenging for many patients. Our team is committed to patient safety and moving forward with the best possible path to deliver ADVM-022 to patients with wet AMD, and potentially delivering a durable new treatment alternative to frequent injections for these patients in the future."

Recent Developments

• At the Association for Research in Vision and Ophthalmology (ARVO) meeting in May, long-term OPTIC clinical data (n=30, March 10, 2021 data cut) were presented demonstrating the potential of ADVM-022 to greatly reduce the anti-VEGF intravitreal (IVT) injection burden for patients with wet AMD. Data demonstrated long-term durability and maintained efficacy with a majority of patients free of supplemental injection following a single, in-office IVT injection of ADVM-022 in difficult-to-treat patients with wet AMD.
• Adverum is no longer planning to develop ADVM-022 for diabetic macular edema (DME) or at the high dose (6 x 10^11 vg/eye). No similar clinically-relevant events like the dose-limiting toxicity (DLT) at the high dose in DME patients have been observed to date in patients with wet AMD, and patients in OPTIC have reached a follow-up period of between 1 and 2.5 years post treatment.
• Adverum is in active discussions to sublease the company's 174,000-square-foot Good Manufacturing Practices (GMP) commercial manufacturing facility in Research Triangle Park, NC. Adverum will leverage its contract manufacturing organization (CMO) partners for ongoing supply of ADVM-022.
  

Anticipated Milestones for ADVM-022:

• Plan to present long-term OPTIC data in wet AMD in 2H21, including 52-week data from Cohort 4 (high dose of 6 x 10^11 vg/eye with steroid eye drop prophylaxis, n=9), at a medical conference
• Plan to present INFINITY data in DME in 2H21 at a medical conference
• Plan to complete data analysis by YE21 to develop a protocol and seek investigator and regulatory feedback on a Phase 2 clinical trial in wet AMD to evaluate low doses (2 x 10^11 vg/eye and lower) of ADVM-022 and alternative prophylactic regimens
  

Financial Results for the Three Months Ended June 30, 2021

• Cash, cash equivalents and short-term investments were $363.8 million as of June 30, 2021, compared to $404.0 million as of March 31, 2021. Adverum expects this quarter-end cash position to fund operations into 2024, 18 months beyond prior guidance of mid-2022. Adverum's cash runway extension is based on current development and manufacturing plans for ADVM-022, including conducting a Phase 2 trial instead of two Phase 3 trials in wet AMD, not pursuing future development in DME, and continuing to utilize contract CMO partners in lieu of establishing a GMP commercial manufacturing facility.
• Research and development expenses were $22.6 million for the three months ended June 30, 2021, compared to $19.2 million for the same period in 2020. Research and development expenses increased primarily due to higher personnel-associated costs, rent expense, clinical trial expenses, consultant and contractor fees, and laboratory costs, partially offset by decreased material production costs. Stock-based compensation expense included in research and development expenses was $2.6 million for the second quarter of 2021, compared to $1.7 million for the same period in 2020.
• General and administrative expenses were $21.9 million for the three months ended June 30, 2021, compared to $10.6 million for the same period in 2020. General and administrative expenses increased primarily due to higher professional services costs, including proxy related fees, personnel-associated costs, and rent for new leases commenced in the second quarter of 2021. Stock-based compensation expense included in general and administrative expenses was $5.7 million for the second quarter of 2021, compared to $3.1 million for the same period in 2020.
• Net loss was $44.3 million, or $0.45 per basic and diluted share, for the three months ended June 30, 2021, compared to $29.2 million, or $0.36 per basic and diluted share, for the same period in 2020.
