Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Infusional fluorouracil/leucovorin plus irinotecan-based regimen (FOLFIRI) with bevacizumab has been widely used as first-line treatment for patients with metastatic colorectal cancer (mCRC). Recently, the investigators have shown that prospective analysis of uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) genotyping for irinotecan dose escalation (FOLFIRI regimen) with combination of bevacizumab biweekly as the first-line setting in mCRC patients (ASCO Abstract #491 - 2013 Gastrointestinal Cancers Symposium).
In this study, the investigators will enroll approximately 320 mCRC patients (It was considered that an increase of response rate of 15% compared to conventional irinotecan dose of 180 mg/m2, and these were chosen as parameters with which to calculate the study power. Initial power calculation was suggested that a minimum of 140 patients in each group would be required to achieve statistical significance with a power of 80% at the 5% significance level. It is estimated that about 10% of 320 mCRC patients fail to complete the study). For these enrolled patients, the investigators will randomize and divide these patients into two groups: control group and study group. Control group includes mCRC patients who will receive the conventional regimen of FOLFIRI plus bevacizumab. Otherwise, patients in the study group will have genotyping of UGT1A1 before therapy, and dose escalating of irinotecan will depend on results of genotyping.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Regimen for treatment consisted of bevacizumab (Avastin) 5mg/Kg (IV infusion) on day 1, follow by irinotecan (180 mg/m2 as a 120-min IV infusion), LV (400 mg/m2 IV infusion over 2 hours), and 5-FU (2800 mg/m2 IV infusion over a 46-hour period), repeated every 2 weeks.
Study group: FOLFIRI (infusional fluorouracil/leucovorin plus irinotecan) + Bevacizumab. The dosage of irinotecan is adjusted to the UGT1A1 genotyping
The wild-type (6/6) of UGT1A1:
Regimen for treatment consisted of bevacizumab (Avastin) 5mg/Kg (IV infusion) on day 1, follow by irinotecan (180 mg/m2 as a 120-min IV infusion), LV (400 mg/m2 IV infusion over 2 hours), and 5-FU (2800 mg/m2 IV infusion over a 46-hour period), repeated every 2 weeks.
After 2 cycles of each different dose of irinotecan, we will observe the adverse effects (AEs) of hematological / non-hematological. If the grade is under the grade 2, we will escalate the dose of 30 mg/m2 gradually. The estimated maximal dose of irinotecan is 260 mg/m2.
The (6,7) type of UGT1A1:
Regimen for treatment consisted of bevacizumab (Avastin) 5mg/Kg (IV infusion) on day 1, follow by irinotecan (180 mg/m2 as a 120-min IV infusion), LV (400 mg/m2 IV infusion over 2 hours), and 5-FU (2800 mg/m2 IV infusion over a 46-hour period), repeated every 2 weeks.
After 2 cycles of each different dose of irinotecan, we will observe the adverse effects (AEs) of hematological / non-hematological. If the grade is under the grade 2, we will escalate the dose of 30 mg/m2 gradually. The estimated maximal dose of irinotecan is 240 mg/m2.
The (7,7) type of UGT1A1:
Regimen for treatment consisted of bevacizumab (Avastin) 5mg/Kg (IV infusion) on day 1, follow by irinotecan (120 mg/m2 as a 120-min IV infusion), LV (400 mg/m2 IV infusion over 2 hours), and 5-FU (2800 mg/m2 IV infusion over a 46-hour period), repeated every 2 weeks.
After 2 cycles of each different dose of irinotecan, we will observe the adverse effects (AEs) of hematological / non-hematological. If the grade is under the grade 2, we will escalate the dose of 30 mg/m2 gradually. The estimated maximal dose of irinotecan is 180 mg/m2.
