About B244

AOB’s B244 platform is a patented, proprietary, topical formulation. Once deployed, B244 produces nitric oxide, a signaling molecule known to regulate inflammation and vasodilation. B244 has been observed to be well-tolerated in clinical studies to date.

Additionally, recently published immunology data demonstrates that B244 can reduce the inflammatory and pruritic cytokines IL-4, IL-5, IL-13, and IL-31.  See full article at:
