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.

Other Name: 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.
