This study will involve two cohorts of patients, A and B. Patients are invited because they have either (A) locally recurrent or metastatic nasopharyngeal cancer; or (B) stage 4 locally advanced nasopharyngeal cancer (N2 or N3 disease and/or T4) and is known to be associated with a high risk of distant relapse.~This study is carried out to find out the safety and recommended dose of CD137L-DC-EBV-VAX in nasopharyngeal cancer. CD137L-DC-EBV-VAX is a product made from one of our own immune system cells (dendritic cell, DC). Dendritic cells are immune cells that help to stimulate our body's T lymphocytes to fight cancer by presenting specific proteins from the cancer cells. The investigators have developed in the laboratory a highly effective dendritic cell which is primed to activate T cells with the Epstein-Barr virus (EBV) proteins. It is hoped that this will stir an immune response to recognize NPC cells and kill them as part of body's immune surveillance system.
