Arms and Interventions

Arm Intervention/Treatment
Experimental: Durvalumab + Placebo

Durvalumab monotherapy: Durvalumab (1500 mg intravenous [IV]) q4w in combination with placebo saline solution (IV) q4w for up to 4 doses/cycles each, followed by durvalumab 1500 mg q4w. The first durvalumab monotherapy 1500 mg dose q4w will be 4 weeks after the final dose of durvalumab in combination with placebo saline solution.

Drug: Durvalumab
Durvalumab IV (intravenous infusion)
Other Names:
  • MEDI4736
  • Other: Placebo
    Placebo IV (intravenous infusion)

    Experimental: Durvalumab + Tremelimumab

    Durvalumab in combination with tremelimumab: Durvalumab (1500 mg IV) q4w in combination with tremelimumab (75 mg IV) q4w for up to 4 doses/cycles each, followed by durvalumab 1500 mg q4w. The first durvalumab monotherapy 1500 mg dose q4w will be 4 weeks after the final dose of durvalumab in combination with tremelimumab.

    Drug: Durvalumab
    Durvalumab IV (intravenous infusion)
    Other Names:
  • MEDI4736
  • Drug: Tremelimumab
    Tremelimumab IV (intravenous infusion)

    Placebo Comparator: Placebo + Placebo

    Placebo: Placebo saline solution (IV) q4w in combination with a second placebo saline solution (IV) q4w for up to 4 doses/cycles each, followed by a single placebo saline solution q4w. The first placebo saline solution monotherapy dose q4w will be 4 weeks after the final dose of the 2 placebo saline solutions in combination.

    Other: Placebo
    Placebo IV (intravenous infusion)

    Outcome Measures

    12. Presence of anti-drug antibodies (ADA) for durvalumab and tremelimumab (confirmatory results: positive or negative) [Approximately 6 years]

    13. PD-L1 expression in tumor and/or immune cells relative to response/efficacy outcomes (PFS, OS & ORR). [Approximately 6 years]

      To investigate the relationship between PDL1 expression & spatial distribution with Durva (mono) therapy & Durva+Treme (combination) therapy

    14. To assess symptoms and health-related QoL in patients treated withdurvalumab or durvalumab and tremelimumab combination therapy compared to placebo using the EORTC QLQ-LC13 [Approximately 6 years]
