    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).
  • Part II: TTP by Biomarker [ Time Frame: 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 ] [ Designated as safety issue: No ]
    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 .

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.

    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.

A Study of Herceptin (Trastuzumab)and Biomarkers in Patients With HER2-Positive Metastatic Breast Cancer
A Prospective Study to Evaluate Alterations in Molecular Biomarkers in HER2 Neu Positive Metastatic Breast Cancer Together With Assessment of Trastuzumab Use Beyond Progression After Initial Response to Trastuzumab-taxane Based Treatment
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.
