BR Metastatic - DOCEtaxel and trastuzumab Q3W
Treatment Overview
This regimen contains a biological anti-cancer medicine where one or more biosimilars may exist. These have been reviewed by the regulator (Medsafe) and by haematologists and/or oncologists nationally. Where haematologists and/or oncologists have agreed that there are no clinically significant differences in either safety or effectiveness between a biosimilar and originator product, these drugs may be used interchangeably. If a prescriber thinks there is a difference, then a specific brand will be named when prescribing.
