Brief summary
The aim of this study is to define the efficacy and safety of Fluzoparib and Camrelizumab in treating patients with recurrent/metastatic nasopharyngeal carcinoma that progressed after first-line chemotherapy.
Detailed description
Currently, the standard first-line treatment for recurrent/metastatic nasopharyngeal carcinoma is cisplatin-based chemotherapy. The recommended subsequent line therapy is single-agent chemotherapy or single-agent PD-1 antibody (nivolumab or pembrolizumab), according to NCCN guidelines (head and neck cancer, version 2021.3). However, the efficacy of nivolumab or pembrolizumab in subsequent line setting is limited, range from 20-30%. In order to improve the efficacy, we launch this study to evaluate whether combination treatment of PARP inhibitor (Fluzoparib) and PD-1 antibody (Camrelizumab) has the potential to increase efficacy in the subsequent line treatment, meanwhile has tolerable adverse effect.
Interventions
Maintenance therapy of Fluzoparib and Camrelizumab, until disease progression or intolerable adverse effect.
