Brief Summary
This single arm study will evaluate alterations in molecular marker expression in HER2-positive targeted therapy, and will evaluate the effect of continued treatment with Herceptin and Xeloda beyond progression following initial Herceptin-taxane chemotherapy. Patients who develop progressive disease will receive first-line Herceptin (8mg/kg iv loading dose and 6mg/kg iv every 3 weeks) + taxane therapy. patients who develop progressive disease within 9 weeks of treatment will continue treatment with Herceptin in combination with Xeloda (1000mg/m2 po bid on days 1-14 of each 3-week cycle).Biopsies of tumor tissue will be taken for biomarker and gene profiling evaluation. The anticipated time on study treatment is until disease progression, intolerable side effects or patient choice, and the target sample size is 100 individuals.

Outcome Measures
Primary Outcomes (6)
Part I: Progression Free Survival (PFS) by Biomarker
Progression was defined as an increase by at least 20 percent (%) from the smallest value in the Sum of Longest Diameter (SLD) of lesions. Biomarkers investigated: p95 human epidermal growth factor receptor 2 (p95HER2) positive (+ve) and negative (-ve) , insulin growth factor-1 receptor (IGF1R) less than (\<) median and greater than or equal to (≥) median membrane H score, c-MET \<median and ≥median membrane H score, phosphatase and tensin homolog gene (PTEN) \<median and ≥median cytoplasm H score, HER2 \<median and ≥median membrane H score, phosphatidylinositol-3-kinase (PI3K) catalytic subunit wild type (WT) and mutation (M), and FC gamma receptors IIIa homozygous Phenyl alanine (FF), heterozygous Phenyl alanine/Valine (VF) and homozygous Valine (VV), receptor IIa Phenotypes homozygous Histidine (HH), heterozygous Histidine/Arginine (HR) and homozygous Arginine (RR) IIb phenotypes homozygous Isoleucien (II),heterozygous Isoleucine/Threonine (IT) and homozygous Threonine (TT) .
End of first 2 Cycles (Weeks 3 and 6), every 3 Cycles for 18 weeks, then every 4 cycles until progression, unacceptable toxicity or participant decision to cease treatment up to 46 months
Part II: Progression Free Survival (PFS) by Biomarker
PFS was calculated from first study medication in Part II to date of progression or death.The relationship between PFS and the following biomarker variables was investigated in each of study Part 1 and 2: p95HER2 +ve and -ve population, IGF1R \<median and ≥ median membrane H score, c-MET \<median and ≥median membrane H score, PTEN \<median and ≥median cytoplasm H score, HER2 \<median and ≥median membrane H score, PI3K catalytic subunit WT and M, and FC gamma receptors IIIa, IIa and IIb Phenotypes FF, VF and VV, HH, HR and RR, and II, IT and TT.
End of first 2 Cycles (Weeks 3 and 6), every 3 cycles for 18 weeks, then every 4 cycles until progression, unacceptable toxicity or participant decision to cease treatment up to 46 months
Part I: Time to Progression (TTP) by Biomarker
Progression was defined as an increase by at least 20% from the smallest value in the SLD of lesions.TTP was determined as the time in months from the date of screening until first progression.The relationship between PFS and the following biomarker variables was investigated in each of study Part 1 and 2: p95 HER2 +ve and -ve population, IGF1R \<median and ≥median, c-MET \<median and ≥median, PTEN \<median and ≥median, HER2 \<median and ≥median, PI3K catalytic subunit WT and M, and FC gamma receptors IIIa, IIa and IIb Phenotypes FF, VF and VV, HH, HR and RR, and II, IT and TT . The correlation between the biomarker variables and TTP were investigated using a univariate Cox regression model and time-to-event methods (Kaplan-Meier).
End of first 2 Cycles (Weeks 3 and 6), every 3 Cycles for 18 weeks, then every 4 cycles until progression, unacceptable toxicity or participant decision to cease treatment up to 46 weeks
Part II: TTP by Biomarker
TTP was calculated from first study medication in Part II to date of progression. The relationship between TTP and the following biomarker variables was investigated in each of study Part 1 and 2: p95 HER2 +ve and -ve population, IGF1R \<median and ≥median, c-MET \<median and ≥median, PTEN \<median and ≥median, HER2 \<median and ≥median, PI3K catalytic subunit WT and M, and FC gamma receptors IIIa, IIa and IIb Phenotypes FF, VF and VV, HH, HR and RR, and II, IT and TT .
End of first 2 Cycles (Weeks 3 and 6), every 3 cycles for 18 weeks, then every 4 cycles until progression, unacceptable toxicity or participant decision to cease treatment up to 46 months
Part I: Percentage of Participants With a Best Overall Response (BOR) of Complete Response (CR), Partial Response (PR), Stable Disease (SD) or Progrerssive Disease (PD) by Biomarker
BOR was defined according to the Response Evaluation Criteria In Solid Tumors (RECIST). CR: disappearance of all target lesions and all pathological lymph nodes below 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions. The relationship between best response and the following biomarkers was investigated: p95 HER2 (+ve/-ve), IGF1R, c-MET, PTEN, HER2 (median/≥median), PI3K catalytic subunit (WT/M), and FC gamma receptors IIIa, IIa and IIb (phenotypes FF, VF, VV, HH, HR, RR and II, IT and TT respectively). The correlation between the biomarker variables and percentage of participants with best response were investigated using a univariate regression analysis.

Part II: Percentage of Participants With a Best Overall Response of CR, PR, SD or PD by Biomarker
Best Overall response was defined according to RECIST. CR: disappearance of all target lesions and all pathological lymph nodes below 10 mm.PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions. The relationship between best response and the following biomarkers was investigated: p95 HER2 (+ve/-ve), IGF1R, c-MET, PTEN, HER2 (\<median/≥median) , PI3K catalytic subunit (WT/M), and FC gamma receptors IIIa, IIa and IIb (phenotypes FF, VF, VV, HH, HR, RR and II, IT and TT respectively). The correlation between the biomarker variables and percentage of participants with best response were investigated using a univariate regression analysis.
