Dr Cate Lockhart Discusses Deciding Between Trastuzumab Biosimilars

How does patient characterization play a role in the use of trastuzumab biosimilars?

You know, so far, no. In our preliminary analysis, we haven't seen any real differences in patient populations who are treated with one or another. It's possible that there are some regional differences. We don't tend to tease that out. Our population in the databases that we work with are fairly broadly distributed around the United States. And we're also looking at commercially insured population. So, there's some limitations for our particular data set.

But in terms of the basic patient characteristics, we haven't really seen anything notably different across them.
