Linsitinib is an experimental drug candidate for the treatment of various types of cancer. It is an inhibitor of the insulin receptor and of the insulin-like growth factor 1 receptor (IGF-1R).^[1] This prevents tumor cell proliferation and induces tumor cell apoptosis.^[2]

Linsitinib was discovered by OSI Pharmaceuticals and is currently in Phase III clinical trials for adrenocortical carcinoma and Phase II clinical trials for lung and ovarian cancers.^[3]^[4]
