Fish Oil Versus Statins Versus Placebos in Reducing Atrial Fibrillation in Patients Undergoing Thoracic Surgery for Lung Cancer

July 31, 2012 updated by: M.D. Anderson Cancer Center

A Double Blinded, Randomized Study Comparing the Effectiveness of Fish Oil Supplements, Oral Statins, and Placebo in Reducing the Incidence of Atrial Fibrillation Following a Lung Resection in Patients With Lung Cancer

The goal of this clinical research study is to learn if Lipitor (atorvastatin) or fish oil supplements can help to control side effects of the heart that are commonly seen after lung surgery (such as irregular heartbeat). Researchers also want to learn if one of these drugs is more effective than the other at controlling side effects.

Study Overview

Detailed Description

The Study Drugs:

Atorvastatin is designed to lower cholesterol by blocking its production in the liver. This may help to decrease the chances of having a heart attack or a stroke.

Fish oil supplements are designed to lower fat levels in the blood by blocking their production in the liver. This may help to decrease the chances of having a heart attack or a stroke.

Atorvastatin is FDA-approved and commercially available for lowering cholesterol or fat levels in the blood. Fish oil supplements are also commercially available.

Researchers want to compare the anti-inflammatory effects of Atorvastatin and fish oil supplements.

Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to a study "Part" based on when you join this study. Up to 132 participants will be enrolled in Part 1 of the study. Up to 120 participants will be enrolled in Part 2 of the study.

If you are enrolled in Part 1, you will be randomly assigned (as in a roll of dice) to 1 of 3 groups. You will be provided with enough unmarked capsules for fourteen days plus a test dose. You will take the test dose in the clinic in the presence of the research nurse. Beginning 5 days before lung surgery (Day -5), you will take 1 capsule in the morning, as well as 3 capsules 2 time each day (a total of 7 unmarked capsules each day) for 5 days. The capsules should be taken with a cup (8 ounces) of water and may be taken with or without food. You will be reminded by the research nurse to bring the remaining capsules from home prior to your admission for surgery.

  • If you are in Group 1, the capsules you will take will be fish oil supplements and placebo. A placebo is a substance that looks like the study drug but has no active ingredients.
  • If you are in Group 2, the capsules you will take will be atorvastatin and placebo.
  • If you are in Group 3, the capsules you will take will be placebo only.

You will have an equal chance of being assigned to each group. Neither you nor the study staff will know if you are receiving the study drug or the placebo. However, if needed for your safety, the study staff will be able to find out what you are receiving.

After Part 1 is complete, the groups will be compared to learn if any group was more effective than the others. If neither fish oil supplements nor atorvastatin is shown to be more effective than the placebo, the study will be stopped. If fish oil or atorvastatin is found to be more effective than the placebo, the study will continue to Part 2.

If you are enrolled in Part 2, you will be randomly assigned to 1 of 2 study groups. You will be provided with enough unmarked capsules for fourteen days plus a test dose. You will take the test dose in the clinic in the presence of the research nurse, and begin taking capsules 5 days before surgery (Day -5) for 5 days. If atorvastatin was found to be the more effective drug in Part 1, you will take 1 unmarked capsule in the morning each day. If fish oil was found to be the more effective drug in Part 1, you will take 3 capsules 2 times each day (a total of 6 unmarked capsules each day). The capsules should be taken with a cup (8 ounces) of water and may be taken with or without food.

You will be reminded by the research nurse to bring the remaining capsules from home prior to admission for surgery.

  • If you are in Group 1, the capsules you will take will be the drug that was found to be more effective in Part 1 (either fish oil supplements or atorvastatin).
  • If you are in Group 2, the capsules you will take will be placebo only.

You will have an equal chance of being assigned to each group. Neither you nor the study staff will know if you are receiving the study drug or the placebo. However, if needed for your safety, the study staff will be able to find out what you are receiving.

Surgery:

After you have taken the study drug/placebo for 5 days, you will have standard of care lung surgery performed. You will be given a separate consent form to read and sign for the surgery.

On the day of surgery, any unused capsules will be collected and the days, times, and reasons why any doses were missed will be recorded. You will then continue taking the study drug/placebo for up to 9 days after surgery or until you are released from the hospital (whichever comes first). You will follow the same dosing schedule you followed before surgery.

Study Visits:

Each day while you are in the hospital, your vital signs will be measured and you will be checked for any allergic reaction you may have had to the study drug/placebo.

On Days 1 and 3, and on the last day that you take the study drug/placebo, blood (about 1 teaspoon) will be drawn to check your liver function.

About 4-6 weeks after surgery, you will have a follow-up visit. At this visit, the following tests and procedures will be performed:

  • You will have a physical exam, including measurement of your vital signs.
  • You will be asked about any symptoms and/or side effects you may have had.
  • Blood (about 1 teaspoon) will be drawn to check your liver function.

Length of Study:

You will take the study drug/placebo for 5 days before surgery, and for up to 9 days after surgery (up to a total of 14 days). Your participation in the study will be over after the follow-up visit. You will be taken off study early if you have intolerable side effects (such as allergic reaction or abnormal liver function tests).

This is an investigational study.

Up to 252 participants will take part in this study. All will be enrolled at M. D. Anderson.
