Outcome Measures
Primary Outcome Measures
- overall response rate (ORR) [at 6 months]
ORR according to RECIST v1.1
Secondary Outcome Measures
- clinical benefit rate, CBR [at 6 months]
CR+PR + SD more than 12 weeks
- median duration of response, DOR [at 6 months]
DOR is related to the quality of life and is one of the methods for evaluating tumor response approved by pharmaceutical regulatory agencies
- median progression free survival, PFS [at 6 months]
from enrollment to disease progression, death or withdrawal
- safety profiles [at 6 months]
safety profiles according to CTCAE 4.0
