Study Of SU011248 Plus Gefitinib (Iressa) In Patients With Advanced Renal Cell Carcinoma

Objective disease response = subjects with confirmed complete response (CR) or partial response (PR) according to RECIST. 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.

TTR was defined as the time from date of the first dose of study medication to first documentation of objective tumor response (CR or PR). For subjects proceeding from PR to CR, the onset of PR was taken as the onset of response. If lesion assessment data included more than 1 date, the first date was used. TTR was calculated as (first event date minus first dose date +1)/7. TTR was calculated based on the subgroup of subjects with a baseline disease assessment, who had the correct histological cancer type, and had a confirmed objective tumor response. Kaplan-Meier method was used.

DR was defined as the time from start of the first documentation of objective tumor response to the first documentation of objective tumor progression or death due 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. DR was calculated for the subgroup of subjects with an objective tumor response (CR or PR).

TTP was defined as the time from the date of first dose of study medication to first documentation of objective tumor progression. If tumor progression data included more than 1 date, the first date was used. TTP (in weeks) was calculated as (first event date minus first dose date +1)/7. Kaplan-Meier method was used.

OS was defined as the time from date of the first dose of study medication to date of death due to any cause. OS (in weeks) is calculated as (date of death minus first dose date +1)/7. For subjects not expiring, their survival times were censored at the last date of known contact they were known to be alive. Subjects lacking data beyond the day of first dose had their survival times censored at 1 day. Kaplan-Meier method was used.

PFS was defined as the time from the date of first dose of study medication to the date of first documentation of tumor progression or death due to any cause, whichever occurred first. If tumor progression data included more than 1 date, the first date was used. PFS (in weeks) was calculated as (first event date minus first dose date +1)/7. Kaplan-Meier method was used.

Survival rate was defined as the percentage of subjects alive at 1 year after the date of first administration of study medication. Survival rate was estimated using the Kaplan-Meier method.

Concentration of VEGF at baseline.

VEGF concentration at each time point divided by VEGF concentration at baseline (ratio to baseline).

Concentration of VEGF-C at baseline.

VEGF-C concentration at each time point divided by VEGF-C concentration at baseline (ratio to baseline).

Concentration of sVEGFR2 at baseline.

sVEGFR2 concentration at each time point divided by sVEGFR2 concentration at baseline (ratio to baseline).

Concentration of sVEGFR3 at baseline.

sVEGFR3 concentration at each time point divided by sVEGFR3 concentration at baseline (ratio to baseline).

Change = median VEGF level at each specified time point for subjects with tumor response (CR or PR or [SD > = 6 weeks] versus PD) minus median VEGF 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).

Change = median VEGFC level at each specified time point for subjects with tumor response (CR or PR or [SD > = 6 weeks] versus PD) minus median VEGFC 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).

Change = median VEGFR2 level at each specified time point for subjects with tumor response (CR or PR or [SD > = 6 weeks] versus PD) minus median VEGFR2 level at Baseline.

Change = median VEGFR3 level at each specified time point for subjects with tumor response (CR or PR or [SD > = 6 weeks] versus PD) minus median VEGFR3 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).

Change = median VEGF level at each specified time point for subjects with tumor response PFS >= Median or PFS < Median minus median VEGF 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).

Change = median VEGFC level at each specified time point for subjects with tumor response PFS >= Median or PFS < Median minus median VEGFC 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).

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).

Change = median VEGFR3 level at each specified time point for subjects with tumor response PFS >= Median or PFS < Median minus median VEGFR3 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).

Change = median VEGF level at each specified time point for subjects with tumor response TTP >= Median and TTP < Median minus median VEGF 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).
