Trastuzumab (TR), a monoclonal antibody approved by EMA in 2000 and one of the first examples of "targeted therapy", is indicated to treat human epidermal growth factor receptor 2 (HER2) positive breast cancer. TR, whose patent will expire in 2015 in Europe, has been judged positively for reimbursement by most public authorities in the EU. Here we critically review the existing evidence on TR in metastatic breast cancer (MBC), in line with the multidisciplinary health technology assessment (HTA) approach, to assess whether the existing evidence supports TR positive reimbursement decisions taken in MBC by EU health authorities. We did a literature search for the main HTA topics (efficacy, quality of life and ethics) on the PubMed international database (2000-2013). Then, we did a specific literature search to select the full economic evaluations (FEEs) conducted in EU countries focused on TR as first-line innovative therapy in MBC. We retrieved scant evidence in the literature to support TR reimbursement in MBC. We found only two clinical trials and their results were unclear because of the large proportion of patients who crossed over. Moreover, the quality of methods was poor in all four European FEEs selected. This example of HTA exercise on a mature monoclonal antibody in a specific indication casts doubts on how often the reimbursement decisions taken by EU health authorities in emotional pathologies like cancer are rational. These decisions should at least be reconsidered periodically on the basis of the latest evidence.

Trastuzumab is a highly successful monoclonal antibody (mAb) that has been used primarily for the treatment of HER2-positive breast cancer. Because of its success and its impending patent expiry in Europe in 2014, a number of copy versions of trastuzumab have been developed and are currently undergoing a comparability exercise for marketing authorization. Although biosimilar products have been approved in Europe since 2006, including two biosimilar mAbs of infliximab approved in 2013, the use of mAbs such as trastuzumab in the cancer setting has raised a number of new concerns. The requirements for the approval of biosimilar mAbs published by the EMA will be discussed and examined in the context of trastuzumab biosimilars to highlight potential controversies.

Biosimilars have demonstrated their equivalence with biologic originators, according to rigorous specifications imposed by the regulatory agencies, the FDA and the EMA. Their development is justified by the very high cost of biopharmaceuticals, and strong incentives for their prescription lead us to hope substantial savings, allowing to finance other innovative molecules. Trastuzumab marked history of the treatment of breast cancer. Four biosimilars of trastuzumab are available for routine use and we will detail the key points of their development.
