Pre-assignment details

Phase 1 only included Cycle 1 for subjects enrolled in Phase 1. Phase 2 was comprised of either Cycle 2 and beyond for subjects who were enrolled in Phase 1, or all cycles for newly enrolled subjects. Additional subjects were enrolled to make a total of 30 in the recommended dose level (50-mg).

Participants by arm

ArmCount
SU-011248 25-mg
Subjects received sunitinib malate (SU-011248) at starting dose of 25-mg once daily. Treatment cycles were 6 weeks in duration, consisting of 4 weeks daily SU-011248 administration followed by 2 weeks off treatment. Phase 1: If Dose Limiting Toxicity (DLT) was observed, the patients were withdrawn from the study treatment. Neither temporary discontinuation nor reduction was permitted. Phase 2: The initial dose could be increased to the recommended dose. Treatment cycles were repeated until a study treatment withdrawal criterion was met. If drug-related adverse event (grade\>=3) was observed, temporary discontinuation or dose reduction were taken according to the criteria.

SU-011248 50-mg
Subjects received sunitinib malate (SU-011248) at starting dose of 50-mg once daily. Treatment cycles were 6 weeks in duration, consisting of 4 weeks daily SU-011248 administration followed by 2 weeks off treatment. Phase 1: If Dose Limiting Toxicity (DLT) was observed, the patients were withdrawn from the study treatment. Neither temporary discontinuation nor reduction was permitted. Phase 2: Treatment cycles were repeated until a study treatment withdrawal criterion was met. If drug-related adverse event (grade\>=3) was observed, temporary discontinuation or dose reduction were taken according to the criteria. From Phase 1 part of this study, 50-mg was determined as the maximum tolerated dose and the recommended dose.

Time frame: Day 28 of Cycle 1

Population: All enrolled subjects who received at least 1 dose of study medication and who had at least 1 blood concentration data for Pharmacokinetic analysis.~3 subjects in 75-mg dose group discontinued before Cycle 1 Day 28, therefore no data presented.

Change From Baseline of European Quality of Life Questionnaire- 5 Dimensions(EQ-5D) Questionnaires

The EQ-5D questionnaires evaluates 5 dimensions of health. The subjects rates the severity of impairment for each dimensions on a 3-point scale(1 to 3). The digits for five dimensions were combined in a five-digit number describing the respondent's health state. Health states were converted into a weighted health state index. High score is indicating high health. Change from Baseline: weighted health state index at each observation minus weighted health state index at baseline
