MLN0415 is a novel, small molecule IKK2 inhibitor, discovered by Millennium scientists. In preclinical studies, MLN0415 was shown to decrease NF-kB activation and down-regulate the expression of a number of inflammatory proteins. Because inflammatory proteins play a critical role in inflammation and drive the inflammatory response to disease, controlling these proteins may prevent or slow disease progression. A Phase I trial to evaluate MLN0415 in inflammatory disorders is underway.
