Abstract:
Recent knowledge about the intermediate steps and final consequences of ligand-dependent epidermal growth factor receptor (EGFR) activation has clearly supported the notion that EGFR plays a fundamental role in regulating the proliferation and survival of malignant neoplasms. Among the rationally designed target-based therapeutics that are being assessed, those targeting EGFR appear to be some of the most clinically relevant. The strategy of using monoclonal antibodies (mAbs) to block ligand binding to the extracellular domain of the EGFR has led to the development of therapeutics that robustly arrest malignant cell proliferation and, in some cases, induce profound tumor regression. The chimeric mAb against EGFR, cetuximab, has already been approved by regulatory agencies worldwide to treat patients with advanced colorectal cancer. Other mAbs against EGFR, particularly panitumumab (ABX-EGF), h-R3, and EMD72000, are in advanced stages of clinical development.
Insights
Epidermal growth factor receptor (EGFR) is crucial for cancer cell growth. Monoclonal antibodies targeting EGFR are effective cancer therapeutics, with cetuximab approved for colorectal cancer.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Epidermal growth factor receptor (EGFR) activation is key in malignant neoplasm proliferation and survival.
- Target-based therapeutics, particularly those inhibiting EGFR, show significant clinical relevance.
Purpose of the Study:
- To review the role of EGFR in cancer.
- To discuss the development and clinical application of EGFR-targeting monoclonal antibodies (mAbs).
Main Methods:
- Review of recent knowledge on EGFR activation pathways.
- Analysis of clinical development stages for EGFR-targeting mAbs.
Main Results:
- EGFR plays a fundamental role in cancer cell proliferation and survival.
