Primary Outcome Measures
NameTimeMethod
PFSFrom enrollment to the end of treatment at 8 weeks

PFS defined as the time from XTD initiation to first documented disease progression, relapse after XTD, death from any cause, or last follow-up.

Secondary Outcome Measures
NameTimeMethod
ORRFrom enrollment to the end of treatment at 8 weeks

The overall response rate (ORR) was defined as the cumulative proportion of patients attaining either a complete response (CR) or partial response (PR) .

OSFrom enrollment to the end of treatment at 8 weeks
