From Wikipedia, the free encyclopedia

Dalotuzumab is an anti-IGF1 receptor (IGF1R) humanized monoclonal antibody designed for the potential treatment of various cancers.[1] Common adverse effects include hyperglycemia, nausea, vomiting, and fatigue.[2] Dalotuzumab was developed by Merck and Co., Inc.[3]

Indications[edit]

Dalotuzumab is indicated to treat breast cancer, colorectal cancer, multiple myeloma, neuroendocrine tumors, non-small cell lung cancer (NSCLC), pancreatic cancer, and solid tumors.[1]

Adverse Effects[edit]

Mechanism of Action[edit]

Insulin-like growth factors (IGFs) are pivotal in cellular processes contributing to normal physiology as well as certain pathologies (e.g., cancer).[3] The IGF family of proteins, also known as the IGF axis, consists of three ligands (insulin, IGF1, IGF2), three cell surface receptors (insulin receptor [IR], IGF1 receptor [IGF1R], IGF2 receptor [IGF2R]), and seven IGF binding proteins (IGFBP1-7).[5] Notably, IGF1R serves as the primary receptor within the IGF axis.[5] The IGF1R is a receptor tyrosine kinase (RTK) with a heterotetrameric structure composed of two extracellular α subunits and two transmembrane β subunits.[3][5] Upon ligand-induced activation of this receptor, cytoplasmic adaptor proteins, Src-homology collagen (Shc) and insulin receptor substrate (IRS), are phosphorylated and, in turn, trigger the activation of the Ras/Raf/MEK/Erk and phosphoinositide 3-kinase (PI3K)/Akt signaling pathways, respectively.[3] These signaling pathways are involved in the regulation of cell survival and cell cycle progression.[3]

Furthermore, IGF1R amplification and overexpression has been observed in the formation of tumors and metastasis of various human cancers.[5] These findings justified the development of anti-IGF1R therapies with the goal of inhibiting aberrant receptor activity and potentially yielding anticancer effects.[3] Among said therapies, Dalotuzumab, a humanized monoclonal antibody, was designed to target and bind the extracellular domains of IGF1R, effectively blocking ligand activation of the receptor and preventing downstream signaling.[3] Moreover, the binding of Dalotuzumab to IGF1R, as seen with other anti-IGF1R antibodies, downregulates the expression of the receptors by prompting the internalization and degradation of IGF1R.[3]

History[edit]

There are now more than 30 different anti-IGF1R candidate drugs involved in over 70 industry and academic-initiated clinical trials.[6]

Dalotuzumab (MK-0646) was developed by Merck and Co., Inc. under license from French pharmaceutical company, Pierre Fabre.[3] Dalotuzumab presently remains in clinical trials and has not been granted FDA approval.[7]
