Patients with controlled infections must undergo periodic monitoring of hepatitis B virus DNA. Note: Patients with hepatitis C (positive hepatitis C virus antibody) who have controlled infection (undetectable hepatitis C virus RNA by PCR either spontaneously or in response to a successful prior course of anti-hepatitis C virus therapy) are permitted.
Have received a live vaccine within 30 days of study Day 1. Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however, intranasal influenza vaccines (eg, Flu-Mist®) are live attenuated vaccines, and are not allowed
