Abstract:The IGF-1R pathway is activated in many cancer types which has led to clinical development of many IGF1R targeted therapeutics. Multiple clinical trials targeting IGF1R are currently underway, however after initial optimism in NSCLC and Ewing's sarcoma, several trials have failed to show efficacy or had severe toxicity. Pretreatment quantitation of tumor IGF1R protein expression remains a challenge due to high homology between IGF1R and the insulin receptor. Thus, there is a need for a specific and quantitativ… Show more
