More than half of the high-grade brain cancers or gliomas over-express epidermal growth factor receptor (EGFR) and for the most advanced brain cancers, glioblastoma multiforme (GBM), the level of expression is even higher. A study involving 29 adults with newly diagnosed high-grade gliomas, including both anaplastic astrocytomas (AA) and GBM, who were treated with surgery, external beam radiotherapy and nimotuzumab showed that the treatment was well tolerated, the median survival time was 17.5 months for the GBM patients, and has not yet been reached for the AA patients.
Nimotuzumab
Nimotuzumab is a humanized monoclonal antibody that targets the epidermal growth factor receptor (EGFR). To date nimotuzumab has been administered to approximately 900 patients in more than a dozen clinical trials and on a compassionate basis. It has been approved in several countries and is being provided on a compassionate basis in certain countries including Canada, Germany, Australia and Japan. The drug continues to demonstrate a significantly more benign side-effect profile compared to all the other EGFR-targeting antibodies and small molecules targeting the EGF tyrosine kinase signalling pathway. The absence of any cases of severe rash to date and the very rare instances of any of the other debilitating side effects holds the prospect for nimotuzumab to become best-in-class for this important family of EGFR-targeting agents.
