Number of Participants With First Cycle Dose-limiting Toxicities (DLTs)
A DLT is any of a predefined set of unacceptable adverse events, regardless of cause. DLTs were assessed during the first cycle (4 weeks).
Time frame: Cycle 1 (Baseline to Week 4)
Maximum Observed Plasma Concentration (Cmax) of Sunitinib, SU-012662, and Total Drug (Sunitinib + SU-012662)
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 2, 4, 6, 8, 10, and 24 hours post-dose)
Time to Reach Maximum Observed Plasma Concentration (Tmax) of Sunitinib, SU-012662, and Total Drug (Sunitinib + SU-012662)
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 2, 4, 6, 8, 10, and 24 hours post-dose)
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of Sunitinib, SU-012662, and Total Drug (Sunitinib + SU-012662)
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 2, 4, 6, 8, 10, and 24 hours post-dose)
Maximum Observed Plasma Concentration (Cmax) of Tegafur and 5-FU
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 1, 2, 4, 6, 8, and 10 hours post-dose)
Time to Reach Maximum Observed Plasma Concentration (Tmax) of Tegafur and 5-FU
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 1, 2, 4, 6, 8, and 10 hours post-dose)
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of Tegafur and 5-FU
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 1, 2, 4, 6, 8, and 10 hours post-dose)
Maximum Observed Plasma Concentration (Cmax) of Total Platinum and Free Platinum
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 0.5, 1, 2, 8, and 22 hours after completing infusion)
Time to Reach Maximum Observed Plasma Concentration (Tmax) of Total Platinum and Free Platinum
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 0.5, 1, 2, 8, and 22 hours after completing infusion)
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of Total Platinum and Free Platinum
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
Time frame: Day 1 of Cycles 1 and 2 (pre-dose, 0.5, 1, 2, 8, and 22 hours after completing infusion)
Number of Participants With Objective Response
Number of participants with objective response-based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR defined as the disappearance of all target lesions. PR defined as greater than or equal to (≥) 30 percent (%) decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. Confirmed responses are those that persist on repeat imaging at least 4 weeks after initial documentation of response.
Time frame: Baseline up to 739 days
Number of Participants With Clinical Benefit Response (CBR)
CBR is defined as a confirmed complete response (CR), confirmed partial response (PR), or stable disease (SD) for at least 24 weeks on study according to RECIST. Confirmed responses are those that persist on repeat imaging at least 4 weeks after initial documentation of response.
Time frame: Baseline up to 739 days
Duration of Response (DR)
Time from the first objective documentation of tumor response (confirmed or partial response) to first documented objective tumor progression or death due to cancer. DR calculated as (the end date for DR minus first subsequent confirmed CR or PR plus 1 day).
Time frame: Baseline up to 739 days
Progression-Free Survival (PFS)
Median time from the enrollment to the first documentation of objective tumor progression or to death due to any cause, whichever occurs first. PFS calculated as (first event date minus enrollment date plus 1 day)
Time frame: Baseline up to 739 days
Time to Progression (TTP)
Time in months from enrollment to first documentation of objective tumor progression. TTP was calculated as (first event date or last known progression-free date minus the date of enrollment plus 1 day). Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease \[PD\] per RECIST).
Time frame: Baseline up to 739 days
