Description
OSI-906 (linsitinib) is an oral dual inhibitor of insulin-like growth factor 1 receptor (IGF-1R) and insulin receptor (IR) that was developed for treatment of various solid tumors including colorectal cancer. The compound targets the IGF/insulin signaling pathway, which plays a role in cancer cell proliferation and survival. In colorectal cancer, OSI-906 has been evaluated as monotherapy with continuous or intermittent dosing schedules, and in combination with everolimus for patients with refractory metastatic disease.
Mechanism of Action
OSI-906 functions by competitively binding to and inhibiting both IGF-1R and IR tyrosine kinases, blocking downstream signaling through the PI3K/AKT and MAPK pathways. This dual inhibition disrupts cancer cell growth, survival signals, and metabolic processes that tumor cells depend on for progression and metastasis.
