Traditional efforts to treat autoimmune conditions have focused on inhibiting proteins involved in the immune response. Abivax is developing therapies that modulate RNA to enhance the body’s natural machinery to disrupt the production of cytokines, the proteins that signal the immune system to mount an attack in the first place. The company’s approach to modulating RNA may not only have utility in autoimmune conditions like inflammatory bowel disease, but in other indications including infectious disease and cancer. We spoke to Hartmut Ehrlich, CEO of Abivax, about the company’s lead therapeutic, how it works, and why the approach can have implications in a broad range of diseases.
