Pre-infusion and post-infusion on Cycle 1 Day 1, Cycle 1 Day 8, Cycle 1 Day 15, pre-infusion and post-infusion on Cycle 2 Day 1, pre-infusion and post-infusion in Cycle 3, 4, 6, 8, 10 and 12

What was measured

Serum samples were collected from the participants at the defined timepoints. Cmax was determined using standard non-compartmental methods.

Analysis population: The pharmacokinetic (PK) analysis set included all participants who received at least 1 dose of study treatment per the clinical study protocol (CSP) for whom any post-dose data were available who did not violate or deviate from the CSP in ways that would significantly affect the PK analysis.

Groups in this outcome

Arm A (>= 35 kg): Durvalumab 20 mg/kg + Tremelimumab 1mg/kg

Participants who weighed \>= 35 kg were administered durvalumab 20 mg/kg IV in Cycle 1 followed by durvalumab in combination with tremelimumab 1 mg/kg IV in Cycles 2-5 every 28 days. From Cycle 6 onwards participants were administered durvalumab 20 mg/kg every 28 days until clinical or confirmed disease progression or until any of other discontinuation criterion was met, whichever occurred first.

Arm A (>= 35 kg): Durvalumab 30 mg/kg + Tremelimumab 1mg/kg

Participants who weighed \>= 35 kg were administered durvalumab 30 mg/kg IV in Cycle 1 followed by durvalumab in combination with tremelimumab 1 mg/kg IV in Cycles 2-5 every 28 days. From Cycle 6 onwards participants were administered durvalumab 20 mg/kg every 28 days until clinical or confirmed disease progression or until any of other discontinuation criterion was met, whichever occurred first.

Arm B (< 35 kg): Durvalumab 20 mg/kg + Tremelimumab 1mg/kg

Participants who weighed \< 35 kg were administered durvalumab 20 mg/kg IV in Cycle 1 followed by durvalumab in combination with tremelimumab 1 mg/kg IV in Cycles 2-5 every 28 days. From Cycle 6 onwards participants were administered durvalumab 20 mg/kg every 28 days until clinical or confirmed disease progression or until any of other discontinuation criterion was met, whichever occurred first.

Arm B (< 35 kg): Durvalumab 30 mg/kg + Tremelimumab 1mg/kg

Participants who weighed \< 35 kg were administered durvalumab 30 mg/kg IV in Cycle 1 followed by durvalumab in combination with tremelimumab 1 mg/kg IV in Cycles 2-5 every 28 days. From Cycle 6 onwards participants were administered durvalumab 20 mg/kg every 28 days until clinical or confirmed disease progression or until any of other discontinuation criterion was met, whichever occurred first.
