Primary Outcome Measures
NameTimeMethod
Number of Subjects With Overall Confirmed Objective Response (OR)From start of treatment through Day 1 of Weeks 5, 9, and every 8 weeks thereafter

OR = subjects with confirmed complete response (CR) or partial response (PR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) persisting \> = 4 weeks after initial documentation of response. A CR was defined as the disappearance of all target lesions. A PR was defined as a ≥ 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.

Secondary Outcome Measures
NameTimeMethod
sVEGFR2 at Baseline Stratified by Tumor Response (CR or PR or [SD > = 12 Weeks] Versus PD)Baseline (Cycle 1, Day 1)

Summary statistics of sVEGFR2 at baseline by group (CR or PR or SD versus PD) are presented.

Duration of Response (DR)From start of treatment through Day 1 of Weeks 5, 9, and every 8 weeks thereafter or death due to any cause

Time from start of the first documentation of objective tumor response (CR or PR) to the first documentation of objective tumor progression or to death due to to any cause, whichever occurred first. If tumor progression data included more than 1 date, the first date was used. DR was calculated as \[the end date for DR minus first CR or PR that was subsequently confirmed +1\]/7.

sVEGFR2 Ratio to Baseline at Each Time PointBaseline to Day 1 of Weeks 3 through 53

Time to Tumor Progression (TTP)From start of treatment through Day 1 of Weeks 5, 9, and every 8 weeks thereafter

Time from date of first dose of study medication to first documentation of objective tumor progression. The 50% quartile point estimate is provided. The criteria for tumor progression was according to RECIST.

Progression-Free Survival (PFS)From start of treatment through Day 1 of Weeks 5, 9, and every 8 weeks thereafter or death

Time from start of study medication to first documentation of objective tumor progression or to death due to any cause, whichever occurred first.

Contains 15 questions. Each question was answered on a 5-point Likert-type scale ranging from 0 to 4 (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much). Total FKSI score = sum score of the 15 item scores; total range: 0 - 60; 0 (most severe symptoms and concerns) to 60 (no symptoms or concerns).
