You will be hospitalized to receive the study drug combination. The morning after you enter the hospital, you will have a catheter placed in your right groin area. A catheter is a sterile flexible tube. It will be placed into a large artery (the blood vessel that carries blood to your liver) while the area is numbed with local anesthetic. Your doctor will explain this procedure to you in more detail, and you will be asked to sign a separate consent form for it.
