Measure Type Secondary
Measure Title Change From Baseline in VEGFR2 by Time Point Stratified by PFS >= Median and PFS < Median
Measure Description Change = median VEGFR2 level at each specified time point for subjects with tumor response PFS >= Median or PFS < Median minus median VEGFR2 level at Baseline. A measure of dispersion is not included because the Wilcoxon rank sum test is a non-parametric test that makes no assumptions about the distribution of the data (eg, normality).
Time Frame Baseline (Cycle 1, Day 1) to Cycle 3, Day 28 inclusive  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
ITT. Number of participants analyzed = number of subjects evaluable for PFS (ie, those who died or had tumor progression) with baseline biomarker values. n=number of subjects with soluble protein biomarkers at baseline and at the specified time point.
