Description of intervention(s) / exposure
Treatment: Other - Pembrolizumab
Treatment: Drugs - Capecitabine

Experimental: Pembrolizumab - Participants receive pembrolizumab 200 mg intravenously (IV) on Day 1 of each 3-week cycle (Q3W) until progressive disease (PD) or unacceptable toxicity for a maximum of up to 35 cycles (up to approximately 2 years). Eligible participants who stop pembrolizumab with Stable Disease (SD) or better but progress after discontinuation may be able to initiate a second course of pembrolizumab 200 mg Q3W for up to 17 cycles (up to approximately 1 additional year).

Active comparator: Standard Treatment - 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 on 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.

Summary
Brief summary
This is a study of pembrolizumab (MK-3475) versus standard 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 standard treatment.

The primary study hypothesis is that pembrolizumab treatment prolongs Overall Survival (OS) when compared to standard treatment.

With Amendment 7 (effective 2-March-2022), upon study completion, participants will be discontinued and may be enrolled in an extension study.
