Primary Outcome Measures
NameTimeMethod
Number of Participants With First Cycle Dose-limiting Toxicities (DLTs)Cycle 1 (Baseline to Week 4)

A DLT is any of a predefined set of unacceptable adverse events, regardless of cause. DLTs were assessed during the first cycle (4 weeks).

Secondary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of Sunitinib, SU-012662, and Total Drug (Sunitinib + SU-012662)Day 1 of Cycles 1 and 2 (pre-dose, 2, 4, 6, 8, 10, and 24 hours post-dose)

Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

Maximum Observed Plasma Concentration (Cmax) of Tegafur and 5-FUDay 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 Sunitinib, SU-012662, and Total Drug (Sunitinib + SU-012662)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 Tegafur and 5-FUDay 1 of Cycles 1 and 2 (pre-dose, 1, 2, 4, 6, 8, and 10 hours post-dose)
Progression-Free Survival (PFS)Baseline up to 739 days

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)

Maximum Observed Plasma Concentration (Cmax) of Sunitinib, SU-012662, and Total Drug (Sunitinib + SU-012662)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 Total Platinum and Free PlatinumDay 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 PlatinumDay 1 of Cycles 1 and 2 (pre-dose, 0.5, 1, 2, 8, and 22 hours after completing infusion)

Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

Number of Participants With Clinical Benefit Response (CBR)Baseline up to 739 days

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.

Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of Tegafur and 5-FUDay 1 of Cycles 1 and 2 (pre-dose, 1, 2, 4, 6, 8, and 10 hours post-dose)

Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

Time to Reach Maximum Observed Plasma Concentration (Tmax) of Total Platinum and Free PlatinumDay 1 of Cycles 1 and 2 (pre-dose, 0.5, 1, 2, 8, and 22 hours after completing infusion)
Number of Participants With Objective ResponseBaseline up to 739 days

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.

Duration of Response (DR)Baseline up to 739 days

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 to Progression (TTP)Baseline up to 739 days

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).
