I did not copy this as a direct link but this study goes over the HERA trial but all participants did receive some type of chemo and then had Herceptin alone (not in combination with chemo as in the USA trials). This site requires you to register which is no problem and has some search capabilities on studies and trial reports. Maybe you can find something but I am not sure anything with Herceptin as an adjuvant (alone without chemo) has been done.
