What was measured

An AE was defined as any untoward medical occurrence in a participant temporally associated with the use of study treatment, whether or not considered related to the study treatment. SAEs were any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a medically important event. Some AEs and higher-level terms were considered AESI or AEPIs and this list of categories were provided by the patient safety team.

Analysis population: The Safety analysis set included all participants who received any amount of study treatment.

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.
