Summary
Brief summary (as posted)
This open-label single arm study will evaluate the efficacy and safety of Avastin added to XELOX or FOLFOX in patients with metastatic colorectal cancer and disease progression on 1st line therapy with FOLFIRI plus Avastin. Patients will receive either Avastin (7.5mg/kg iv infusion every 3 weeks) and standard XELOX (Xeloda \[capecitabine\] plus oxaliplatin) chemotherapy or Avastin (5 mg/kg iv infusion every 2 weeks) and standard FOLFOX (5-FU and leucovorin plus oxaliplatin) chemotherapy. The anticipated time on study treatment is until disease progression, and the target sample size is 100 individuals.

- Progression-Free Survival (PFS) From the Start of Treatment Beyond Progression
- timeFrame
- Baseline, every 9 weeks until disease progression, at end of treatment or withdrawal, for up to 24 months
- description
- PFS from the start of treatment beyond progression was defined as the interval between the start of beyond-progression therapy and the date at which disease progression was documented. Progression of disease was evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) criteria version 1.1 and abdominal/pelvic computerized tomography (CT) or magnetic resonance imaging (MRI) scanning as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. The same method of assessment and the same technique were to be used to evaluate each lesion throughout the entire study. If more than one method was used, data from the most accurate method according to RECIST were recorded. Median PFS was estimated using the Kaplan-Meier method.
