• Has received prior anticancer therapy or thoracic radiation therapy within 14 days before the first dose of study treatment
• Has ≥Grade 2 non-hematological residual toxicities from prior therapy
• Has had a prior anticancer monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤Grade 1 or at baseline) from AEs due to agents administered ≥4 weeks earlier

• Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis
• Has an active infection requiring intravenous systemic therapy
• Has a known history of human immunodeficiency virus (HIV) infection
• Has known, active hepatitis B or hepatitis C infection
• Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of study treatment
