Scientific rationale for extrapolation of cancer indications
Extrapolation involves extending and applying the data from clinical studies regarding one medical condition to another medical condition. Once biosimilarity has been proven, biosimilars can also be approved for one or more additional indications held by the reference product, without the need for clinical data in those indications. Author Michinori Ogura from the Tokai Central Hospital, Gifu, Japan and colleagues from France and South Korea investigated the scientific rationale for extrapolation using the rituximab biosimilar CT-P10 as an example [1].

Trastuzumab biosimilar could reduce breast cancer treatment costs
Trastuzumab is a monoclonal antibody that interferes with the human epidermal growth factor receptor 2 (HER2)/neu receptor.
