• Non-healed dental/oral surgery, including tooth extraction
• Planned invasive dental procedures
• Evidence of any of the following conditions per subject self-report or medical chart review:
• Any prior invasive malignancy within 5 years before randomization
• Any non-invasive malignancy not treated with curative intent or with knownactive disease within 5 years before randomization
• Major surgery or significant traumatic injury occurring within 4 weeks before randomization
• Active infection with Hepatitis B virus or Hepatitis C virus
• Known infection with human immunodeficiency virus (HIV)
• Active infection requiring IV anti-infective therapy
• Subject is pregnant or breast feeding, or planning to become pregnant within 5 months after end of treatment
• Female subject of child bearing potential is not willing to use highly effective contraception during treatment and for 5 months after the end of treatment (see section 6.3)
