What Avalo Therapeutics, Inc. does

In the company’s own words

Avalo Therapeutics, Inc. (Nasdaq: AVTX) is a clinical-stage biotechnology company developing treatments for immune-mediated inflammatory diseases, with a focus on therapies that inhibit interleukin-1 beta (IL-1β). Its lead candidate, abdakibart, is a humanized monoclonal antibody designed to neutralize IL-1β and is being evaluated in a Phase 2 trial for hidradenitis suppurativa, a chronic inflammatory skin disease. The trial enrolls approximately 250 adults with moderate to severe disease. Avalo also has legacy candidates targeting LIGHT, mTOR, and B and T lymphocyte attenuator pathways, as well as a preclinical candidate for a mitochondrial disorder; it is not currently pursuing clinical development of these programs and is exploring strategic alternatives. The company acquired rights to abdakibart through its 2024 acquisition of AlmataBio, including licenses from Eli Lilly and Leap Therapeutics, and is responsible for its development and commercialization. Avalo relies on contract manufacturers to supply its product candidates and has limited sales and marketing resources.
