Primary Outcome Measures:
  • Identification of potential plasma biomarkers of response to peptide immunotherapy [ Time Frame: 6 months after start of dosing ]
    Blood samples derived from the study will be submitted for proteomics analyses aimed at the identification of one or more plasma proteins whose concentration over the course of the study varies in relation to the treatment administered. The outcome will be determined on the basis of measurements from samples collected over a period commencing prior to treatment and ending 6 months following treatmen
