This open-label study will assess the efficacy and safety of Avastin (bevacizumab) plus Xeloda (capecitabine) in combination with standard technique radiotherapy of the pelvic region in the neo-adjuvant setting in patients with locally advanced primary rectal cancer. Patients will receive 4 courses of Avastin at a dose of 5 mg/kg intravenously (iv) every 2 weeks and for 38 days Xeloda at dose of 825 mg/kg twice daily orally, plus radiation therapy. After surgery, adjuvant treatment with 5-fluorouracil/leucovorin and, at the discretion of the investigator, with Avastin 5 mg/kg iv every 2 weeks for at least 6 months will be given.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Pathological complete response rate (pCR) after chemo-radiotherapy (histologic tumour assessment by local and central pathologist) [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Clinical tumour and lymph node response to chemo-radiotherapy (assessments by endosonography, rectosigmoidoscopy, pelvic and abdomen CT scan or MRI) [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
  • Sphincter-saving procedure rate after pre-operative chemo-radiotherapy [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • Disease-free survival (tumor assessments by endosonography, rectosigmodoscopy and pelvic and abdomen CT scan or MRI) [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
  • Overall survival [ Time Frame: approximately 5 years ] [ Designated as safety issue: No ]
