Biological therapy with cediranib improves survival in women with recurrent ovarian cancer
Date:9/30/2013

Women with ovarian cancer that has recurred after chemotherapy have survived for longer after treatment with a biological therapy called cediranib, according to new results to be presented today (Monday) at the 2013 European Cancer Congress (ECC2013) [1].

Cediranib, which is taken in pill form, is an inhibitor of a cell signalling process involved in formation of tumour blood vessels, essential for tumour growth, and it is the first oral inhibitor of its kind to show an improvement in the time before patients' disease progresses and in overall survival. The drug is a tyrosine kinase inhibitor, a type of biological therapy that blocks vascular endothelial growth factor (VEGF) receptors, which control the development of blood vessels required for growing tumours.

Professor Jonathan Ledermann, Professor of Medical Oncology at UCL Cancer Institute, University College London, presented first results from ICON6, an international randomised, double-blind, academic clinical phase III trial of cediranib.

"In women whose ovarian cancer had been treated with platinum-based chemotherapy together with cediranib given during and after the chemotherapy, we found that the time before the tumour started to grow again was extended by an average of 3.2 months. This sounds like a modest increase but represents about a 30% improvement, with overall survival also increased by a similar amount, to an average of 2.7 months over a two-year period of follow-up," he said.

Studies with chemotherapy alone have shown that the time before patients experience disease progression following treatment for a relapse that is sensitive to platinum-based chemotherapy is an average of eight to nine months. These latest results show that cediranib in addition to chemotherapy increased the time before the disease progressed from 9.4 to 12.6 months over a period of two years, and it extended overall survival from 17.6 to 20.3 months.
