  • Vaccination within 4 weeks of the first dose of avelumab and while on study.
  • Ongoing immunosuppressive therapy.
  • Use of a strong inhibitor or inducer of cytochrome P450 3A4 (CYP3A4) within 7 days prior to the start of study therapy or expected requirement for use of a strong CYP3A4 inhibitor or inducer during study therapy.
