Colorectal Cancer RECHALLENGE

This study has been withdrawn prior to enrollment.
Information provided by:
Sanofi Identifier:
First received: September 28, 2009
Last updated: December 21, 2009
Last verified: December 2009

Primary Objective:

  • To demonstrate that re-challenge with an oxaliplatin based regimen (modified FOLFOX-6) will provide a clinical disease control rate (DCR) of at least 20% at the end of the chemotherapy.

Secondary Objective:

  • To evaluate other measures of tumour's responses and safety.

Further study details as provided by Sanofi:

Primary Outcome Measures:
  • Primary endpoint for the first thirteen patients according to the Simons Design: Clinical DCR (Disease Control Rate) at the end of stage I, based on Response Evaluation Criteria on Solid Tumors (RECIST) criteria. [ Time Frame: At the end of 8 cycles or end of treatment which occurs first. ]

Secondary Outcome Measures:
  • Progression-free survival (PFS) [ Time Frame: evaluated at 10 weeks, 16 weeks and 40 weeks ]
  • Duration of response [ Time Frame: evaluated at 10 weeks, 16 weeks and 40 weeks ]
  • Adverse events [ Time Frame: At each visit, i.e. every two weeks ]
  • Overall response rate of stage I and II [ Time Frame: evaluated at week 14 ]

Enrollment: 0
Study Start Date: October 2009
Estimated Study Completion Date: May 2012
Estimated Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1

Patients will receive modified FOLFOX-6 regimen:

  • oxaliplatin 85mg/m2, day 1 (given as a 2-hour infusion)
  • LV 400mg/m2, day 1 (given as a 2-hour infusion simultaneous to oxaliplatin)
  • 5-FU given as a bolus IV 400mg/m2 dose on day 1 followed by 2400mg/m2 continuous infusion over 46 hours (day 1 and 2)

A cycle is defined as 2 weeks. Patients will receive cycles of modified FOLFOX-6 regimen every 2 weeks up to a maximum of 8 cycles. Use of bevacizumab is at the discretion of the treating physician.
