Study of FOLFIRI Plus Bevacizumab in Colorectal Cancer Patients

2011年9月14日 更新者:M.D. Anderson Cancer Center

Phase II Study of Irinotecan, Leucovorin, 5-Fluorouracil (FOLFIRI) Plus Bevacizumab as First-Line Treatment for Metastatic Colorectal Cancer

Objectives:

  1. To estimate progression-free survival (PFS) at 12 months in subjects with metastatic colorectal cancer who receive FOLFIRI [folinic acid (leucovorin or LV), 5-Fluorouracil (5-FU), irinotecan) plus bevacizumab as first line treatment.
  2. To determine the objective response rate and the duration of objective response in this population.
  3. To assess overall survival (OS) in this population.
  4. To measure the effect of treatment on intratumoral blood volume and microvascular permeability by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in consenting patients in whom it is technically feasible.
  5. To correlate plasma proteomics with response.
  6. To assess the safety of this regimen.

調査の概要

詳細な説明

Colorectal cancer growth may be affected by a protein in the body called "vascular endothelial growth factor" (VEGF). A drug that blocks VEGF may be an effective treatment for colorectal cancer. Bevacizumab is designed to block VEGF. Bevacizumab will be added to 5-Fluorouracil (5-FU), leucovorin (LV), and irinotecan, a drug combination routinely used in the treatment of advanced colorectal cancer.

Before you can start treatment on the study, you will have what are called "screening tests". These tests will help the doctor decide if you are eligible to take part in the study. You will be asked questions about your medical history and about any medications you are currently taking or have taken in the past. You will have a complete physical exam and your heart rate, temperature, breathing rate, blood pressure, height, and weight will be measured. You will be asked about your ability to perform every day activities. You will have an electrocardiogram (ECG - a test that measures the electrical activity of the heart). You will have a chest x-ray and scans (either computed tomography (CT) or magnetic resonance imaging (MRI)) of your abdomen and pelvis to evaluate the cancer. Scans of other parts of your body also may be taken if your doctor thinks they are needed to evaluate your cancer. Blood (about 3 tablespoons) and urine samples will be collected for routine tests, including complete blood count, carcinoembryonic antigen (CEA) level (a marker for your cancer), and chemistry profile. Women who are able to have children must have a negative blood or urine pregnancy test

If the screening evaluations show you are eligible to take part in the study, you may begin treatment Study treatment is repeated every 2 weeks (14 days). Each 14-day period of treatment is called a "cycle" of therapy. You must receive study treatment at M. D. Anderson.

All study drugs will be given through a needle into a vein. For your first treatment, you will receive bevacizumab alone first. The first dose of bevacizumab will be given over about 90 minutes. If you do not have a reaction (such as fever/chills), the next dose will be given over about 60 minutes, and if again no reaction occurs, each dose after that will be given over about 30 minutes. If you experience a reaction to the bevacizumab infusion, you may be given acetaminophen (such as Tylenol) by mouth and/or an antihistamine by vein over 30 minutes before each dose to help decrease the risk of further reactions.

Fourteen (14) days later and for all future cycles, you will receive bevacizumab, LV, and irinotecan given on Day 1 of each cycle. 5-FU is given over 46 hours over Days 1-3.

Bevacizumab will be given as described above. When the bevacizumab infusion ends, you will receive LV and irinotecan, starting at the same time. You will receive irinotecan over 90 minutes and LV over 2 hours. When the LV infusion ends, 5-FU will be given over 2 to 4 minutes. This is followed by more 5-FU given over 46 hours using a small portable pump (about the size of a standard paperback book).

Before each new cycle of study treatment, you will be asked questions about any side effects you may have had and about any medications you are currently taking or have taken since you last saw the study doctor. You will have a complete physical exam, including measurements of blood pressure, pulse, temperature, and weight. You will be asked about your ability to perform every day tasks. About 3 tablespoons of blood will be taken for routine laboratory tests. These tests include a complete blood count and chemistry profile. A urine sample will be taken before every other cycle of treatment. During the first cycle of treatment, on Day 8, you will have a sample of blood (about 3 teaspoons) drawn. This test may be done at a lab close to your home.

You will also have either CT scans or MRI of the tumor(s) every 8 weeks and at the end of the study treatment. About 1 tablespoon of blood will be taken to check your CEA level at the same time scans are done. Additional tests may be done during the study if your doctor feels it is necessary for your care. Except for the weekly blood test, which may be done at a lab close to home, all testing and evaluations must be done at M. D. Anderson.

If you experience severe side effects, treatment may be delayed, stopped, or you may receive smaller doses of the treatment. You may continue to receive study treatment unless the disease gets worse, you decide not to take part any longer, or your doctor decides it is in your best interest to stop treatment.

When you stop study treatment, you will be asked to have some tests and evaluations done at an end of study visit. Urine and about 3 tablespoons of blood will be taken for routine laboratory tests, including complete blood count, CEA level, and chemistry profile. You will also have a physical exam. CT scan or MRI scan of your abdomen and pelvis will also be done to check the size and location of your disease.

Once you stop receiving study treatment, the study doctor or nurse will continue to check how you are doing, either in the clinic or by telephone if you stop coming to M. D. Anderson, every 3 months for the rest of your life.

This is an investigational study. The drugs used in this study are approved by the FDA for treatment of advanced colorectal cancer. Up to 43 patients will take part in this multicenter study. About 38 will be enrolled at M. D. Anderson.
