The addition of sorafenib (Nexavar) to standard chemotherapy or hormone therapy for metastatic breast cancer patients won't extend progression-free survival, according to findings presented at the 2011 European Multidisciplinary Cancer Congress by researchers from Milan's San Raffaele Research Institute.
218 patients took part in the phase II trial (FM-B07-01) of sorafenib, a tyrosine kinase inhibitor with anti-angiogenic and anti-proliferative activity that is currently indicated for renal and hepatocellular carcinoma (kidney and liver cancers).
The primary endpoint was progression-free survival, and findings showed that sorafenib was no better than a placebo when combined with docetaxel (Taxotere) or letrozole (Femara).
