SHP647, a fully human IgG2 monoclonal antibody, binds to human mucosal addressin cell adhesion molecule-1 (MAdCAM-1) to reduce lymphocyte homing to the gastrointestinal tract. SHP647 was well tolerated in a randomized, double-blind phase 2 trial (TURANDOT I; NCT01620255) in patients with ulcerative colitis (UC) over 12 weeks.
