If you have hepatitis B, hepatitis C, or HIV infection, you will remain on the study as long as you are benefiting, until 12 months after your chemotherapy treatment ends, or until the study closes. Researchers may continue to check your medical record for up to 18 months after study enrollment or for up to 12 months after your chemotherapy treatment ends. If you are still receiving chemotherapy when the study closes, you will have the option to continue with your care off of the study.
