Primary Outcome Measures :
  1. Definition of a biomarker (profile) characterizing "good responders" to dual blockade T and P anti-HER2 blockade that have similar pCR rates as patients treated with identical dual anti-HER2 blockade + taxane backbone [ Time Frame: After 12 weeks of therapy ]
    pCR will be measured after 12 weeks of randomized treatment.
