Study & Design

Arm && Interventions

Group	Intervention	Description
Comprehensive treatment	Triprilimab(JS001)	Patients with multiple metastatic NPC were given Triprilimab(JS001) and chemotherapy combined with local treatment.

Primary Outcome Measures

Name	Time	Method
Progression-Free Survival(PFS)	2 year	PFS was defined as the time from diagnosis of metastasis to first documented disease progression (PD) using Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) or death from any cause, whichever occurred first. For target lesions, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum of the longest diameter recorded since treatment started or the appearance of 1 or more new lesions. For non-target lesions, PD was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions.

Secondary Outcome Measures

Name	Time	Method
ORR	2 year	Objective response rate
DCR	2 year	Disease contral rate
