Study Arms:
- Pembrolizumab 2 mg/kg (Type: EXPERIMENTAL): Participants were initially randomized to receive pembrolizumab 2 mg/kg intravenously (IV) once every 3 weeks (Q3W). With Amendment 03, this dosing was discontinued and all study participants were to be treated with fixed-dose open label pembrolizumab 200 mg IV Q3W. Participants were to receive study drug until discontinuation due to progression of disease, toxicity, or choice. (Up to \~66 months)
- Pembrolizumab 10 mg/kg (Type: EXPERIMENTAL): Participants were initially randomized to receive pembrolizumab 10 mg/kg IV Q3W. With Amendment 03, this dosing was discontinued and all study participants were to be treated with fixed-dose open label pembrolizumab 200 mg IV Q3W. Participants were to receive study drug until discontinuation due to progression of disease, toxicity, or choice. (Up to \~66 months)
- Investigator-Choice Chemotherapy (ICC) (Type: ACTIVE_COMPARATOR): Participants were initially randomized to receive 1 of 4 possible chemotherapy regimens decided at the treating institution (carboplatin+paclitaxel, paclitaxel alone, dacarbazine, or temozolomide). Participants were to receive study drug until discontinuation due to progression of disease, toxicity, or choice. (Up to \~66 months)
- ICC→Pembrolizumab 2 mg/kg (Type: EXPERIMENTAL): Participants who were initially randomized to ICC, subsequently experienced confirmed progressive disease (PD) and met all switching criteria at study treatment Week 12, had the opportunity to switch to receive pembrolizumab 2 mg/kg or 10 mg/kg. Participants received pembrolizumab 2 mg/kg IV Q3W. With Amendment 03, this dosing was discontinued and all study participants were to be treated with fixed-dose open label pembrolizumab 200 mg IV Q3W. Participants were to receive study drug until discontinuation due to PD, toxicity, or choice. (Up to \~66 months)
- ICC→Pembrolizumab 10 mg/kg (Type: EXPERIMENTAL): Participants who were initially randomized to ICC, subsequently experienced confirmed progressive disease (PD) and met all switching criteria at study treatment Week 12, had the opportunity to switch to receive pembrolizumab 2 mg/kg or 10 mg/kg. Participants received pembrolizumab 10 mg/kg IV Q3W. With Amendment 03, this dosing was discontinued and all study participants were to be treated with fixed-dose open label pembrolizumab 200 mg IV Q3W. Participants were to receive study drug until discontinuation due to PD, toxicity, or choice. (Up to \~66 months)
