Sponsor's own description

Primary Objective: (i) To identify panels of RNAs and proteins predictive of response to HER2 targeted agents, considering clinical responses. (ii) To investigate associations between presence vs. absence (or relative levels) of identified extracellular (EC) RNAs/proteins and patients' clinicopathological characteristics, including age at diagnosis, time to progression and overall survival, as well as correlations with serum protein biomarkers routinely analysed for these patients. (iii) To compare HER2 positive samples versus HER2 negative samples for the existence of RNAs/proteins identified in (i) and (ii). Secondary Objective: To develop a predictive model for use in the HER2 positive population based on the most accurate and sensitive combination of the identified biomarkers.
