First- and particularly second-line metastatic colorectal cancer have become very crowded treatment settings, with multiple combinations of chemotherapies and targeted agents competing for the same patient subsets.

However, the branded drug is approaching the end of its lifecycle and the recent launch of bevacizumab biosimilars will significantly erode its market share.
