Description
Dalotuzumab (MK-0646) is a humanized monoclonal antibody that targets the insulin-like growth factor-1 receptor (IGF-1R) pathway. This targeted therapy has been evaluated in metastatic colorectal cancer, particularly in combination with established treatments like cetuximab and irinotecan. The drug was developed to block IGF-1R signaling, which promotes tumor cell growth and survival in various cancer types including colorectal cancer.
Mechanism of Action
Dalotuzumab binds specifically to the insulin-like growth factor-1 receptor (IGF-1R), blocking the binding of IGF-1 and IGF-2 ligands to this receptor. This inhibition disrupts downstream signaling pathways including PI3K/AKT and MAPK pathways, which are critical for cancer cell proliferation, survival, and metastasis.
