Abstract

Background: Despite advances in targeted therapy for lung Cancer, survival for patients remains poor and lung Cancer remains the leading cause of cancer-related deaths worldwide. The type I insulin-like growth factor receptor (IGF-IR) has emerged as a potential target for lung Cancer treatment, however, clinical trials to date have provided disappointing results. Further research is needed to identify if certain patients would benefit from IGF-IR targeted therapies and the ideal approach to incorporate IGF-IR targeted agents with current therapies.

Methods: The dual IGF-IR/Insulin Receptor Inhibitor, BMS-754807, was evaluated alone and in combination with platinum-based chemotherapeutics in two human non-small cell lung Cancer (NSCLC) cell lines. Cell survival was determined using WST-1 assays and drug interaction was evaluated using Calcusyn software. Proliferation and Apoptosis were determined using immunofluorescence for phospho-histone H3 and cleaved Caspase 3, respectively.

Results: Treatment with BMS-754807 alone reduced cell survival and wound closure while enhancing Apoptosis in both human lung Cancer cell lines. These effects appear to be mediated through IGF-IR/IR signaling and, at least in part, through the PI3K/Akt pathway as administration of BMS-754807 to A549 or NCI-H358 cells significantly suppressed IGF-IR/IR and Akt phosphorylation. In addition of BMS-754807 enhanced the cytotoxic effects of carboplatin or cisplatin in a synergistic manner when given simultaneously to A549 cells.

Conclusions: BMS-754807 may be an effective therapeutic agent for the treatment of NSCLC, particularly in lung Cancer cells expressing high levels of IGF-IR.
