Drug Overview
Etrolizumab (Roche) is a humanized anti-beta7 integrin subunit monoclonal antibody.
The drug was discovered by Genentech, which was acquired by Roche in 2009. Etrolizumab binds to the beta7 subunit of the alpha4-beta7 and alphaE-beta7 integrin heterodimers. This prevents the interaction of alpha 4-beta7 integrin with mucosal addressing cell adhesion molecule-1 and the interaction of alphaE-beta7 integrin with E-cadherin.
In turn, this results in interference with immune cell trafficking into the intestine in a selective manner that avoids broad immunosuppression.
The drug is in late-phase development in Crohn’s disease and ulcerative colitis. The US Food and Drug Administration has granted orphan drug designation to Etrolizumab for pediatric patients.
