  Purpose

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.

Further study details as provided by Ottawa Hospital Research Institute:

Primary Outcome Measures:
  • 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 ] [ Designated as safety issue: Yes ]
  • 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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Response rates and duration of response [ Time Frame: every 2 cycles - 6 weeks ] [ Designated as safety issue: No ]
  • Overall survival [ Time Frame: continuous ] [ Designated as safety issue: Yes ]
  • Qualitative and quantitative toxicity [ Time Frame: continuous ] [ Designated as safety issue: Yes ]

Enrollment: 23
