Scientific title | A randomised trial assessing the role of two new agents in the management of advanced colorectal cancer |
Study acronym | MRC FOCUS (Fluorouracil, Oxaliplatin, CPT-11, Use and Sequencing) |
Study objectives | 1. The principal objective is to determine whether there is an advantage for patients for the use of combination chemotherapy for colorectal cancer compared with the standard approach of sequential single-agent therapies. 2. In addition the trial will determine whether combination therapy is best used in first-line management of advanced disease, or reserved for second-line treatment following standard first-line single-agent modified de Gramont (MdG). 3. Finally, the trial will compare the efficacy and toxicity of an irinotecan-containing combination versus the equivalent oxaliplatin-containing combination. |
Ethics approval(s) | Added 17/07/2007: Northern and Yorkshire Medical Research Ethics Committee, approval given on 12/11/1999. |
Health condition(s) or problem(s) studied | Colorectal cancer |
Intervention | This is a five-arm trial in which patients will be randomly allocated to one of five 'treatment plans'. These plans comprise first-line and, in some cases, a second-line chemotherapy treatment plan. The five plans are: Plan A: First-line Modified de Gramont (MdG) regimen. In the event of radiological or clinical disease progression, MdG will be stopped, and, if appropriate, patients will receive second-line therapy with single-agent irinotecan. Plan B: First-line MdG. In the event of radiological or clinical progression patients will, if appropriate, receive second-line therapy with MdG-plus-Irinotecan (IrMdG). Plan C: First-line treatment with IrMdG. Plan D: First-line MdG. In the event of radiological or clinical progression patients will, if appropriate, receive second-line therapy with MdG-plus-Oxaliplatin (OxMdG). Plan E: First-line treatment with OxMdG. The chemotherapy schedules employed in the plans are as follows: MdG: l-folinic acid 175 mg iv infusion over two hours 5-fluorouracil 400 mg/m^2 intravenous bolus over five minutes 5-fluorouracil 2800 mg/m^2 intravenous infusion over 46 hours Cycle repeat: 14 days Irinotecan (single agent): Irinotecan 300-350 mg/m^2 intravenous infusion over 30 minutes Cycle repeat: 21 days IrMdG: Irinotecan 180 mg/m^2 intravenous infusion over 30 minutes l-folinic acid 175 mg/m^2 intravenous infusion over two hours 5-fluorouracil 400 mg/m^2 intravenous bolus over five minutes 5-fluorouracil 2400 mg/m^2 intravenous infusion over 46 hours Cycle repeat: 14 days OxMdG:Oxaliplatin 80 mg/m^2 intravenous infusion over two hours concurrent with l-folinic acid 175 mg intravenous infusion over two hours 5-fluorouracil 400 mg/m^2 intravenous bolus over five minutes 5-fluorouracil 2400 mg/m^2 intravenous infusion over 46 hours Cycle repeat: 14 days In every case, chemotherapy schedules are continued for at least 24 weeks unless disease progression or unacceptable toxicity occurs. Dose reductions or delays for toxicity are defined in the full protocol. |
