|
Number of participants with objective response based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST.
Confirmed CR defined as disappearance of all target lesions.
Confirmed PR defined as ≥30% decrease in sum of the longest dimensions (LD) of the target lesions taking as a reference the baseline sum LD according to RECIST.
Confirmed responses are those that persist on repeat imaging study ≥4 weeks after initial documentation of response.

|
Overall Survival (OS)
大体时间:Baseline, assessed monthly until death or 7.5 months after last participant was enrolled (up to January 2011)
|
OS is time from baseline to death from any cause.

Baseline, assessed monthly until death or 7.5 months after last participant was enrolled (up to January 2011)
|
Progression Free Survival (PFS)
大体时间:Baseline, assessed monthly until death or 7.5 months after last participant was enrolled (up to January 2011)
|
PFS is time from baseline to first progression (Prog) or death from any cause.
Participants last known to be alive, had not started a new (non-protocol) cancer treatment, were Prog-free, and who had a baseline and ≥1 on-study disease assessment were censored at date of last objective disease assessment that verified lack of Prog.
Participants who were off treatment prior to Prog and who had no on-study disease assessment were also censored.
Prog: ≥20% increase in sum of longest dimension (LD) of target lesions from smallest sum LD recorded since treatment start or appearance of ≥1 new lesions.

Criteria for progression also included unequivocal progression of existing nontarget lesions.

Area under the serum concentration time-curve from time zero to the last measured concentration.
AUClast analyzed using a noncompartmental approach to estimate individual participant values.
|
