Abstract:
The epidermal growth factor receptor (EGFR) is a promising target for cancer therapy and a number of EGFR-targeted agents have been developed. Those most advanced in development are the EGFR tyrosine kinase inhibitors gefitinib ('Iressa', ZD1839) and erlotinib ('Tarceva', OSI-774), and the monoclonal antibody cetuximab ('Erbitux', IMC-C225). This review provides a clinical overview of these agents, highlighting their antitumour activities in different tumour types. Epidermal growth factor receptor-targeted agents are generally well tolerated and are not typically associated with the severe adverse events often seen with cytotoxic chemotherapy. Gefitinib is the agent with the most extensive clinical experience, particularly in non-small-cell lung cancer (NSCLC). Recently, gefitinib became the first-approved EGFR-targeted agent, for use in patients with previously treated advanced NSCLC in Japan, the USA and other countries. Further studies are required to explore the full potential of these novel agents either as monotherapy or combination therapy.
Insights
Epidermal growth factor receptor (EGFR) targeted therapies, including gefitinib, erlotinib, and cetuximab, show promise in cancer treatment. These agents are generally well-tolerated and are being investigated for various tumor types, with gefitinib approved for non-small-cell lung cancer.
Area of Science:
- Oncology
- Pharmacology
Background:
- The epidermal growth factor receptor (EGFR) is a key target in cancer therapy.
- Several EGFR-targeted agents, including tyrosine kinase inhibitors and monoclonal antibodies, have been developed.
Purpose of the Study:
- To provide a clinical overview of advanced EGFR-targeted agents.
- To highlight their antitumour activities and tolerability in different tumour types.
Main Methods:
- Review of clinical data for gefitinib, erlotinib, and cetuximab.
- Analysis of antitumour activity and adverse event profiles.
Main Results:
- EGFR-targeted agents demonstrate antitumour activity across various cancers.
- These agents are generally well-tolerated compared to cytotoxic chemotherapy.
- Gefitinib has extensive clinical experience, particularly in non-small-cell lung cancer (NSCLC), and is approved in several countries.
Conclusions:
- EGFR-targeted agents represent a significant advancement in cancer therapy.
- Further research is needed to optimize their use in monotherapy and combination regimens.
