OSI-906

OSI-906 (Linsitinib) is an orally small-molecule inhibitor of IGF-1R with potential antineoplastic activity. IGF-1R has been viewed as an important therapeutic target due to its involvement in the growth and proliferation in a variety of human cancers, including adrenocortical carcinoma (ACC), ovarian and non-small cell lung cancers. A major challenge in the development of IGF-1R inhibitors is to avoid blocking the closely related insulin receptor that regulates glucose levels in the blood. OSI-906 (Linsitinib) selectively inhibits IGF-1R, which may result in the inhibition of tumor cell proliferation and the induction of tumor cell apoptosis. Overexpressed in a variety of human cancers, IGFR-1 stimulates cell proliferation, enables oncogenic transformation, and suppresses apoptosis. OSI-906 slowed the growth of IGF-1R-dependent tumors, and it also reduced proliferation and/or survival of a broad panel of tumor cell lines.
