Tidsramme
Percentage of Participants With Objective Tumor Response According to Response Evaluation Criteria in Solid Tumors (RECIST)
Tidsramme: At the end of every even-numbered cycle (cycle=28 days) up to a maximum of 12 cycles and 4 to 6 weeks following initial documentation of response
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.
At the end of every even-numbered cycle (cycle=28 days) up to a maximum of 12 cycles and 4 to 6 weeks following initial documentation of response
Overall Survival (OS)
Tidsramme: 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. Participants last known to be alive were censored at the date of last contact.
Baseline, assessed monthly until death or 7.5 months after last participant was enrolled (up to January 2011)
Progression Free Survival (PFS)
Tidsramme: 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.
Baseline, assessed monthly until death or 7.5 months after last participant was enrolled (up to January 2011)
Time to Progression
Tidsramme: Monthly until death or 7.5 months after last participant was enrolled (up to January 2011)
Disease progression defined as ≥20% increase in sum 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.
Monthly until death or 7.5 months after last participant was enrolled (up to January 2011)

FDG PET assessment to characterize and monitor tumors before and after study treatment; measured as a standardized uptake value (SUV). A reduction in SUV from baseline for at least 1 tumor may indicate a positive metabolic response to treatment.

Tidsramme: At the end of every even-numbered cycle (cycle=28 days) and 4 to 6 weeks following initial documentation of response
CA 19-9 or sialylated Lewis (a) antigen (a tumor marker). Values higher than 37 units per milliliter (U/ml) considered abnormal; higher values usually indicate greater presence of disease.
