Summary
The purpose of this randomized controlled Phase II study is to assess the efficacy of
PDR001 versus investigator's choice of chemotherapy in patients with advanced
nasopharyngeal carcinoma (NPC).
By blocking the interaction between PD-1 and its ligands PD-L1 and PD-L2, PDR001 leads to
the activation of a T-cell mediated antitumor immune response.
