Description of intervention(s) / exposure
Treatment: Other - Pembrolizumab
Other interventions - Placebo

Experimental: Pembrolizumab - Participants receive 200 mg pembrolizumab (2 mg/kg for a maximum of 200 mg in pediatric participants) by intravenous (IV) infusion once every 3 weeks (Q3W; 21-day cycles) for up to 17 cycles (up to \~1 year) in Part 1. Participants who complete the initial treatment of 17 cycles of pembrolizumab and experience disease recurrence may be eligible for re-challenge with pembrolizumab at the same dose and schedule of 200 mg Q3W (21-day cycles) for up to 35 cycles (up to \~2 years) in Part 2.

Placebo comparator: Placebo - Participants receive saline placebo by IV infusion Q3W (21-day cycles) for up to 17 cycles (up to \~1 year) in Part 1. Participants who complete the initial treatment of 17 cycles of placebo and experience disease recurrence may be eligible to switch over to pembrolizumab 200 mg Q3W (21-day cycles) for up to 35 cycles (up to \~2 years) in Part 2.
