• Expected cash, cash equivalents, and short-term investments of approximately $112 million as of September 30, 2025.
• The company's cash runway is projected to extend into 2028.
• AVTX-009 has broad potential for indication expansion into other IL-1 driven diseases, including various arthritis indications and inflammatory bowel disease.

Risks

• Significant risks and uncertainties exist that could cause actual results to differ from forward-looking statements.
• Risks are associated with the integration of AVTX-009 into operations.
• Drug development costs, timing of trial results, and other risks, including reliance on investigators and enrollment of patients in clinical trials, pose challenges.
• Reliance on key personnel is a risk factor.
• Regulatory risks are inherent in pharmaceutical development.
• General economic and market risks and uncertainties, including those caused by geopolitical conflicts, could impact operations.
• Other risks detailed in Avalo's filings with the Securities and Exchange Commission.

Future Outlook

The company projects its lead compound, AVTX-009, to have a best-in-class and best-in-disease profile for hidradenitis suppurativa (HS), a market expected to exceed $10 billion by 2035. Topline data from the Phase 2 LOTUS trial in HS is anticipated by mid-2026, with initiation of a pivotal program projected for 2027. The company also expects its cash runway to extend into 2028.

Management Comments

• Avalo Therapeutics is advancing the next-generation of IL-1 inhibition for immune-mediated inflammatory diseases.
• The management team has a proven track record of successful leadership, product development, and commercialization in pharma and biotech.
• Our approach involves next-generation therapies targeting IL-1, a master regulator of inflammation.
• Our lead asset, AVTX-009, is a high-affinity, IL-1 specific monoclonal antibody.
• AVTX-009 has a differentiated profile with 15x higher affinity and a longer half-life than lutikizumab, offering potential for best-in-class and best-in-disease efficacy with less frequent dosing.
• Hidradenitis Suppurativa (HS) is our lead indication, projected to become a $10B+ market by 2035, driven by growth in diagnosis and treatment, and high patient need due to incomplete response rates for available anti-TNF and anti-IL-17 therapies.
• We have clinical momentum with the Phase 2 LOTUS trial in HS enrolling and topline data expected mid-2026.
• AVTX-009 has broad potential, with scientific and clinical rationale for expansion into additional IL-1 driven diseases.
• We maintain a strong financial foundation with an expected cash runway into 2028.

Industry Context

The filing positions AVTX-009 as a next-generation IL-1 inhibitor in the immune-mediated inflammatory disease space, specifically targeting hidradenitis suppurativa (HS). This aligns with a broader industry trend of developing targeted biologics for chronic inflammatory conditions where existing anti-TNF and anti-IL-17 therapies show incomplete or diminishing responses. The focus on IL-1β as a key immunoregulator in HS suggests a strategic move to address a specific pathway, potentially offering a differentiated treatment option in a growing market.

Comparison to Industry Standards

• AVTX-009 demonstrates 15x higher affinity and a longer half-life than lutikizumab, potentially leading to higher efficacy and less frequent dosing.
• AbbVie's lutikizumab (IL-1α/β) showed favorable efficacy compared to market leaders and pipeline therapeutics in a refractory HS population that had failed anti-TNF therapy.
• IL-1β (not IL-1α) is identified as a key immunoregulator in HS, differentiating AVTX-009's specific IL-1β targeting from broader IL-1α/β or IL-1α specific agents.
• Bermekimab, an IL-1α specific monoclonal antibody, performed no better than placebo in a Phase 2 HS study that included an adalimumab comparator arm.
• Current anti-TNF (e.g., Humira) and anti-IL-17 (e.g., Cosentyx) biologic therapies for HS have limited efficacy, with a large proportion of patients still reporting significant symptoms.
• The HS market is projected to grow to over $10 billion by 2035, driven by increased diagnosis and treatment, with new approvals expected to increase biologic treatment share to approximately 40% of the segment, as evidenced by the rapidly growing use of Cosentyx and Bimzelx.

Stakeholder Impact

• Shareholders: Potential for increased shareholder value if AVTX-009 trials are successful and the HS market grows as projected. The strong cash runway provides financial stability.
• Patients (HS): Potential for a new, more effective treatment option for hidradenitis suppurativa, addressing significant unmet needs and potentially improving quality of life.
• Employees: Continued employment and potential growth opportunities as the company advances its pipeline and expands its operations.
• Healthcare Providers: Introduction of a new therapeutic option to consider for managing HS patients.

Next Steps

• Continue enrollment in the Phase 2 LOTUS trial for Hidradenitis Suppurativa (HS).
• Anticipate topline data readout from the Phase 2 LOTUS trial by mid-2026.
• Initiate a pivotal program in 2027, pending the Phase 2 readout.
• Assess additional immunology indications for investment.

Key Dates

Recommendation

The investor presentation outlines a compelling investment thesis centered on AVTX-009, a differentiated IL-1β inhibitor targeting the large and underserved hidradenitis suppurativa market. The drug's superior affinity and half-life compared to competitors, coupled with strong clinical rationale for IL-1β in HS, suggest a high potential for best-in-class efficacy. The company has a clear clinical development path with a Phase 2 readout expected mid-2026 and a robust financial foundation with a cash runway into 2028. This combination of strong clinical prospects, significant market opportunity, and financial stability makes it an attractive 'buy' for investors seeking exposure to the biopharmaceutical sector.
