ATN-161

ATN-161 is a non-RGD based integrin binding peptide targeting alpha-5 beta-1 and alpha-v beta-3. It inhibits the migration and adhesion of particular integrins on activated endothelial cells that play a critical role in tumor angiogenesis. This approach targeting both the tumor vasculature and the cancer cells themselves, may be effective in single therapy as well as combination therapy. Since the expression of alpha(5)beta(1) integrin by cancer cells and the role of this molecule in tumor angiogenesis is similar across a range of different cancers, the therapeutic benefit of ATN-161 is expected to extend to a variety of cancers.
