Outcomes
Primary Outcomes
Objective response rate (ORR)
Time Frame: Week9/17/25/33 and every 12 weeks after (up to 2 years)
ORR: the proportion of patients with confirmed complete response (CR) or partial response (PR), assessed by the independent review committee (IRC) according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1.
Duration of response (DoR)
Time Frame: Week9/17/25/33 and every 12 weeks after (up to 2 years)
DoR: the duration from the first evaluation as CR or PR to the first evaluation as progressive disease (PD) or death of any cause, per RECIST v1.1 assessed by investigator (INV) and IRC.
Disease control rate (DCR)
Time Frame: Week9/17/25/33 and every 12 weeks after (up to 2 years)
DCR: the proportion of patients whose overall response is confirmed to be CR or PR or stable disease (SD) per RECIST v1.1, assessed by INV and IRC.
Overall survival (OS)
Time Frame: from the first date of Infigratinib treatment until date of death.
from the first date of Infigratinib treatment until date of death.
Investigator evaluated ORR
Time Frame: Week9/17/25/33 and every 12 weeks after (up to 2 years)
the proportion of patients with confirmed CR or PR assessed by INV according to RECIST v1.1
Progression-free survival (PFS)
Time Frame: Week9/17/25/33 and every 12 weeks after (up to 2 years)
the duration from the first date of treatment to the date of progression or death due to any cause, assessed by INV and IRC
