Brief Summary:
Triplets of irinotecan, oxaliplatin and infusional 5-fluorouracil(FU)/leucovorin (LV) are associated with high response rates and long survival as first-line treatment for metastatic colorectal cancer (mCRC). The oral fluoropyrimidine, capecitabine, is better tolerated and shows better response rates than 5-FU/LV in metastatic colorectal cancer. A phase I dose-escalation study established dose limiting toxicity (DLT), maximum tolerated dose (MTD) and recommended phase II doses (RPIID) of irinotecan, oxaliplatin and capecitabine. This phase I /II study is to determine dose-limiting toxicities (DLTs), maximum tolerated dose (MTD), phase II recommended dose (RD) of IXO and bevacizumab combination and safety at the RD in an expanded cohort.

Drug Information available for: Bevacizumab

Arm Intervention/treatment
Experimental: IXO regimen + bevacizumab
This is phase I/II safety and efficacy study. There is only one arm of Irinotecan, Xeloda and Oxaliplatin (IXO) regimen with Avastin (bevacizumab)
Drug: IXO regimen + bevacizumab

Phase I study - identifies the safety of IXO with bevacizumab and recommended phase II dose

Phase II study - assesses efficacy and safety of IXO with bevacizumab

Other Names:
  • irinotecan - Camptosar
  • capecitabine - Xeloda
  • Oxaliplatin - Eloxatin
  • bevacizumab - Avastin

Primary Outcome Measures :
  1. Phase I: Assess the MTD and RD for phase II of IXO and bevacizumab combination given every 3 weeks in 1st line patients with mCRC [ Time Frame: 3-week cycle, continuous monitoring of AE ]
  2. Phase II: Using the RD established in phase I, assess efficacy of the IXO with bevacizumab combination as measured by progression-free survival [ Time Frame: 3-week cycle, continuous monitoring of AE ]

Secondary Outcome Measures :
  1. Response rates and duration of response [ Time Frame: every 2 cycles - 6 weeks ]
  2. Overall survival [ Time Frame: continuous ]
  3. Qualitative and quantitative toxicity [ Time Frame: continuous ]
