This is a study of pembrolizumab (MK-3475) versus standard of care (SOC) treatment (capecitabine, gemcitabine, or docetaxel) for the treatment of recurrent or metastatic nasopharyngeal cancer (NPC). Participants will be randomly assigned to receive either pembrolizumab or Investigator's choice of SOC treatment.
The primary study hypothesis is that pembrolizumab treatment prolongs Overall Survival (OS) when compared to SOC treatment.

|Estimated Study Completion Date :||May 28, 2022|
Participants receive pembrolizumab 200 mg intravenously (IV) on Day 1 of each 3-week cycle until progressive disease (PD) or unacceptable toxicity or a maximum of up to 35 cycles.
Active Comparator: Standard of Care Chemotherapy
Participants receive capecitabine 1000 mg/m^2 orally (PO) twice each day (BID) on Days 1-14 of each 3-week cycle OR gemcitabine 1250 mg/m^2 IV Days 1 and 8 of each 3-week cycle OR docetaxel 75 mg/m^2 IV on Day 1 of each 3-week cycle until PD or unacceptable toxicity.
