Adverum Biotechnologies, Inc. (NASDAQ:ADVM) is a clinical-stage gene therapy company focused on developing treatments for highly prevalent ocular diseases. The company's lead product candidate, ixoberogene soroparvovec (Ixo-vec), formerly known as ADVM-022, is being evaluated for the treatment of wet age-related macular degeneration (wet AMD), a leading cause of blindness in patients over 65 years of age.

Financials

For the full year 2023, Adverum reported annual revenue of $3.6 million, primarily driven by a milestone payment received from its licensing agreement with Lexeo Therapeutics. However, the company incurred a net loss of $117.2 million and generated negative operating and free cash flows of $91.3 million and $92.1 million, respectively, as it continued to invest heavily in the development of its pipeline.

In the first quarter of 2024, Adverum reported a net loss of $24.8 million, a decrease from the $29.1 million net loss recorded in the same period of 2023. The company's research and development expenses decreased by $5.6 million to $15.4 million, primarily due to a reduction in spending on Ixo-vec as the company completed two clinical trials. General and administrative expenses also decreased by $1.4 million to $11.4 million.

Adverum's cash, cash equivalents, and short-term investments stood at $193.3 million as of March 31, 2024, up from $96.5 million at the end of 2023. This increase was largely due to the company's successful completion of a private placement in February 2024, which raised $127.8 million in gross proceeds.

Business Overview

Ixo-vec: Adverum's Lead Product Candidate for Wet AMD

Ixo-vec is a single, in-office intravitreal (IVT) injection gene therapy product designed to deliver long-term, durable therapeutic levels of the anti-vascular endothelial growth factor (VEGF) protein aflibercept. This approach aims to reduce the treatment burden and fluctuations in macular fluid associated with frequent anti-VEGF IVT injections, which are the current standard of care for wet AMD.

In the ongoing LUNA Phase 2 trial, Ixo-vec has demonstrated promising preliminary safety and efficacy data. At the 6 x 10^10 vg/eye (6E10) and 2 x 10^11 vg/eye (2E11) doses, Ixo-vec resulted in favorable reductions in annualized anti-VEGF injections and the percentage of subjects remaining free of injections, consistent with results observed in the earlier OPTIC trial. Importantly, Ixo-vec was well-tolerated, and any intraocular inflammation present was responsive to the per-protocol local corticosteroid regimen.

Regulatory Designations and Partnerships

Ixo-vec has received several regulatory designations that could expedite its development and approval process. In September 2018, the FDA granted Ixo-vec Fast Track designation, and in June 2022, the European Medicines Agency (EMA) granted it Priority Medicines (PRIME) designation. More recently, in April 2023, the UK's Medicines and Healthcare products Regulatory Agency (MHRA) granted Ixo-vec an Innovation Passport under the Innovative Licensing and Access Pathway (ILAP).

Adverum has also established a licensing agreement with Lexeo Therapeutics for the development of a gene therapy product to treat cardiomyopathy due to Friedreich's Ataxia. Under the terms of the agreement, Adverum is eligible to receive additional milestone payments and royalties on net sales.

Risks and Challenges

Adverum's Ixo-vec faces competition from a number of other gene therapy and biologic products in development for the treatment of wet AMD, including REGENXBIO's RGX-314, Kodiak Sciences' KSI-301, and Novartis' Beovu. These therapies aim to improve efficacy, durability, and/or convenience compared to the current standard of care.

Additionally, Adverum may face challenges in manufacturing and scaling up its production capabilities to meet potential future demand for Ixo-vec. The company currently relies on third-party manufacturers and suppliers, and any disruptions or quality issues in the supply chain could impact the development and commercialization of its product candidates.

Outlook

Looking ahead, Adverum's success will largely depend on the continued development and potential regulatory approval of Ixo-vec for the treatment of wet AMD. The company plans to initiate a Phase 3 clinical trial for Ixo-vec in the first half of 2025, which will be a critical milestone in its path to commercialization.

Risks to Adverum's business include the potential for delays or setbacks in its clinical trials, manufacturing challenges, competition from other therapies, and the ability to secure adequate funding to support its operations and development activities. Additionally, the company's reliance on third-party partners for key aspects of its business, such as clinical trials and manufacturing, introduces additional risks and uncertainties.

Conclusion

Adverum Biotechnologies is a promising gene therapy company focused on addressing the significant unmet medical need in the treatment of wet AMD. With its lead candidate Ixo-vec demonstrating encouraging preliminary results and regulatory designations that could expedite its development, Adverum is well-positioned to potentially disrupt the current standard of care. However, the company faces a competitive landscape and must navigate the challenges of scaling up its manufacturing capabilities and securing sufficient funding to support its ambitious clinical and commercial plans. Investors will closely monitor Adverum's progress as it advances Ixo-vec through late-stage clinical trials and works towards potential regulatory approval and commercialization.
