RATIONALE: Drugs used in chemotherapy, such as fluorouracil, oxaliplatin, and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug, combination chemotherapy, may kill more tumor cells. Studying samples of blood in the laboratory from patients with cancer receiving fluorouracil in combination with oxaliplatin and leucovorin calcium may help doctors learn how fluorouracil works in the body and how patients will respond to treatment.
PURPOSE: This phase I trial is studying biomarker-guided fluorouracil in treating patients with colorectal cancer receiving combination chemotherapy.
|Condition or disease||Intervention/treatment||Phase|
|Colorectal Cancer Diarrhea Neutropenia||Drug: fluorouracil Drug: leucovorin Drug: oxaliplatin||Phase 1|
- To determine whether 4 courses of pharmacokinetic (PK)-guided 5-fluorouracil chemotherapy improves the ability to achieve a targeted area under the curve (20 to 25 mg*hr/L) in patients with colorectal cancer receiving mFOLFOX6 chemotherapy as compared to historical non-PK-guided therapy in patients treated with a similar FOLFOX regimen.
- To determine and compare the incidence of neutropenia and diarrhea in patients treated with these regimens.
OUTLINE: This is a multicenter study.
- Standard mFOLFOX6 (course 1): Patients receive fluorouracil IV bolus over 1-5 minutes followed by fluorouracil IV continuously over 46 hours, oxaliplatin IV over 2 hours, and leucovorin calcium IV over 2 hours on day 1.
Patients undergo plasma sample collection periodically during study for pharmacokinetic (PK)-guided fluorouracil dose determination for courses 2-4.
- PK-guided mFOLFOX6 (courses 2-4): Patients receive fluorouracil bolus, oxaliplatin, and leucovorin calcium as in course 1. Patients also receive fluorouracil* IV continuously as determined by the PK-guided analysis.
NOTE: *The continuous infusion fluorouracil dose adjustment is calculated based on the results of PK plasma concentrations and the corresponding AUC from the preceding course.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||76 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Multicenter Study Investigating Utilization of Pharmacokinetic-Guided 5-Fluorouracil in Patients Receiving mFOLFOX6 With or Without Bevacizumab|
|Study Start Date :||February 2010|
|Primary Completion Date :||November 2012|
|Study Completion Date :||September 2013|
Patients will receive cycle 1 of standard dose mFOLFOX6, with the same dose of mFOLFOX6 continued in subsequent cycles, once patient achieves the target AUC.
mFOLFOX 6 is a regimen comprised of Oxaliplatin + Leucovorin +5-Fluorouracil (FU)
