At the IBC Antibody Engineering Conference in San Diego, X-Body Biosciences reported that it has discovered and optimized its first lead anti-angiogenesis compound, XB2202, from its DNA display and sequencing platform. The compound satisfied the requirements for a lead compound, including inhibition of receptor phosphorylation in renal carcinoma cells and inhibition of retinal pericyte migration, through its binding of platelet-derived growth factor receptor beta (PDGFRB).
