SU011248 In The Treatment Of Patients With Bevacizumab (Avastin)-Refractory Metastatic 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.

TTP was defined as the time from the date of first dose of study medication to the date of the first documentation of 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.

DR was defined as the 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 that occurred within 28 days after the last dose of study medication, whichever occurred first. If tumor progression data included more than 1 date, the first date was used. DR was only calculated for the subgroup of subjects with a confirmed objective response. DR was calculated as [the end date for DR minus first CR or PR that was subsequently confirmed +1]/7. Kaplan-Meier method was used.

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

PFS was defined as the time from start of study medication to first documentation of objective tumor progression or to death due to any cause that occurred on treatment including within 28 days after the last dose of study medication, 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.

Plasma concentrations of VEGF-A that may be associated with tumor proliferation or angiogenesis collected from a subset of subjects were analyzed by ELISA analysis. Samples below the limit of quantitation and samples with insufficient volume available were excluded.

Plasma concentrations of sVEGFR-3 that may be associated with tumor proliferation or angiogenesis collected from a subset of subjects were analyzed by ELISA analysis. Samples below the limit of quantitation and samples with insufficient volume available were excluded.

Plasma concentrations of PlGF that may be associated with tumor proliferation or angiogenesis collected from a subset of subjects were analyzed by ELISA analysis. Samples below the limit of quantitation and samples with insufficient volume available were excluded.

Plasma concentrations of VEGF-C that may be associated with tumor proliferation or angiogenesis collected from a subset of subjects were analyzed by ELISA analysis. Samples below the limit of quantitation and samples with insufficient volume available were excluded.

Plasma concentrations of sVEGFR-2 that may be associated with tumor proliferation or angiogenesis collected from a subset of subjects were to have been analyzed by ELISA analysis; however, no data were collected.
