Abstract
Background: Bevacizumab is a new humanised monoclonal antibody which targets vascular endothelial growth factor (VEGF) and thereby the neoangiogenic process in cancer. Bevacizumab has shown promising anti-tumour effect when given concurrently with taxane-based chemotherapy in breast cancer. However two neoadjuvant breast cancer trials have produced conflicting results. The NSABP-B40 study showed significant benefit for bevacizumab only in the ER+ve patients (pathological complete response (pCR) in ER+ve population 15.2% vs 23.3%, p=0.008). Whereas the GEPARQUINTO trial reported significant benefit only in the triple negative patients (pCR 27.8% vs 36.4% p=0.021). Methods: ARTemis is a phase III randomised trial to determine whether the addition to neo-adjuvant chemotherapy of bevacizumab is more effective than standard chemotherapy alone in patients with HER2-negative early breast cancer. A total of 400 patients will be randomised into each of the two treatment arms which will allow an absolute difference in the pCR rates in excess of 10% to be detected at the 5% (2-sided) level of significance with an 85% power. Primary outcome is pathological complete response rates after neo-adjuvant chemotherapy, i.e. no residual invasive carcinoma in the breast, and no evidence of metastatic disease within the lymph nodes. Secondary outcomes are disease free survival, overall survival, complete pathological response rates in breast alone, radiological response after 3 and 6 cycles of chemotherapy and rate of breast conservation and toxicities. Results: Recruitment into ARTemis began in April 2009 and as of January 2012 had recruited 469 (59%). ARTemis is due to complete recruitment by Dec 2012 and the first planned interim analysis of the primary outcome will be Dec 2013. Conclusion: The IDSMC reviewed the trial in June 2011 and recommended continuation of recruitment to this important trial given there were no safety concerns, and results from the other neoadjuvant studies (NSABP-B40 and GEPARQUINTO) are conflicting.
