What is the purpose of this trial?

This trial tests a combination of nanatinostat, valganciclovir, and pembrolizumab in patients with certain EBV-related cancers. Nanatinostat makes cancer cells more vulnerable, allowing valganciclovir to kill them, while pembrolizumab boosts the immune system to fight the cancer.
