Revolo Biotherapeutics' ‘1104, derived from Mycobacterium tuberculosis, targets antigen-presenting cells to shift the immune system from a pro-inflammatory to a homeostatic state, potentially providing remission for allergic diseases. It acts upstream in the inflammatory response, reducing IL-4 and IL-13 signaling via SHP-1 activation, and increases regulatory T and B cells. This upstream approach contrasts with traditional therapies, offering potential for more durable disease control and fewer side effects. Preclinical and clinical findings support its broad-spectrum efficacy across Th2-driven conditions like eosinophilic esophagitis, asthma, and atopic dermatitis, with potential for less frequent dosing and long-term remission.
