Avalo Therapeutics, Inc. is a clinical-stage biotechnology company focused on the treatment of immune dysregulation. The Company's lead asset is AVTX-009, an anti-IL-1β mAb, targeting inflammatory diseases. AVTX-009 is a humanized monoclonal antibody (IgG4) that binds to interleukin-1β (IL-1β) with high affinity and neutralizes its activity. IL-1β is a central driver in the inflammatory process. Overproduction or dysregulation of IL-1β is implicated in many autoimmune and inflammatory diseases. IL-1β is a major, validated target for therapeutic intervention. There is evidence that inhibition of IL-1β could be effective in hidradenitis suppurativa and a variety of inflammatory diseases in dermatology, gastroenterology, and rheumatology. AVTX-009 is in the Phase II LOTUS trial for hidradenitis suppurativa (HS).
