Time in days from the first documentation of objective tumor response to objective tumor progression or death due to any cause. Duration of tumor response was calculated as the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first CR or PR that was subsequently confirmed plus 1. DR was calculated for the subgroup of participants with a confirmed objective tumor response.

Time in days from the start of study treatment to date of death due to any cause. OS was calculated as the death date minus the date of first dose of study medication plus 1. Death was determined from AE data (where outcome was death) or from follow-up contact data (where the participant current status was death). For participants who were alive, overall survival was censored at the last contact.

Plasma concentrations of soluble proteins (vascular endothelial growth factor [VEGF], placental growth factor [PlGF] and soluble vascular endothelial growth factor receptor-2 [sVEGFR2]) may be associated with tumor angiogenesis or tumor physiology and may correlate with efficacy or biological activity. It is presented as ratio to baseline, which is obtained by dividing the plasma soluble protein concentration at each time point by its concentration at baseline.

Time in days from start of study treatment to first documentation of objective tumor progression or death due to any cause. PFS was calculated as (first event date minus the date of first dose of study medication plus 1). Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD]), or from adverse event (AE) data (where the outcome was "Death").

ITT population included all participants who received at least 1 dose of study medication.

Subgroup of participants from the ITT population with a confirmed objective tumor response (CR or PR).

Time in days from the start of study treatment to date of death due to any cause. OS was calculated as the death date minus the date of first dose of study medication plus 1. Death was determined from AE data (where outcome was death) or from follow-up contact data (where the participant current status was death).

Population pharmacokinetic analysis involved mixed effects modeling using nonlinear mixed effects modeling (NONMEM) software. The intent of this analysis was to establish a basic population pharmacokinetic model for axitinib (AG-013736) and to determine inter-individual and residual variability in population (oral) clearance, and volume of distribution of drug. Relationship of demographic variables (gender, age, body weight, height and ethnicity), concomitant medications and measures of altered hepatic and renal function were examined by fitting measured axitinib (AG-013736) concentrations.

Population pharmacokinetic values were not summarized as descriptive statistics since the data was not available for the single study and data for all the axitinib (AG-013736) Phase 2 studies would be pooled together in a separate report.
