Primary Outcome Measures
NameTimeMethod
Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)From screening until 28 days post last dose of study drug

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A SAE was an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Objective Response (OR)Baseline, assessed every 6 weeks starting from Day1 of Cycle 3 up to end of treatment (Day 1344)

Percentage 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). Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. CR are defined as disappearance of all target lesions. PR are those with at least 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.

Progression-free Survival (PFS)Baseline, assessed every 6 weeks starting from Day1 of Cycle 3 up to end of treatment (Day 1344)

Time in weeks 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) divided by 7. 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").

Duration of Response (DR)Baseline, assessed every 6 weeks starting from Day1 of Cycle 3 up to end of treatment (Day 1344)

Time in weeks from the first documentation of objective tumor response to objective tumor progression or death due to any cancer. 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) divided by 7. DR was calculated for the subgroup of participants with a confirmed objective tumor response.

Plasma Trough Concentrations (Ctrough) of SU011248 (Sunitinib), SU012662 (Sunitinib Metabolite) and Total Drug (SU011248+SU012662)Pre-dose (0 hours [H]) on Day 1 and Day 15 of Cycle 2, 4, 6 and additionally Day 15 of Cycle 1

Ctrough = the concentration prior to study medication administration. Ctrough was calculated for SU011248 (Sunitinib), SU012662 (Sunitinib metabolite) and total drug (SU011248+SU012662). Concentration values below the lower limit of quantification were taken as zero.

Maximum Observed Plasma Concentration (Cmax) of DocetaxelEnd of infusion (1 H) on Day 1 of Cycle 1, 2, 4 and 6

Concentration values below the lower limit of quantification were taken as zero.

Plasma Trough Concentrations (Ctrough) of TrastuzumabWeekly trastuzumab: Pre-dose (0 H) on Day 1 and 15 of Cycle 1, 2, 4 and 6; 3-weekly trastuzumab: Pre-dose (0 H) on Day 1 of Cycle 1, 2, 4 and 6

Ctrough = the concentration prior to study medication administration.
