CT-P6, a proposed biosimilar to trastuzumab, exhibited long-term disease-free survival (DFS) and overall survival (OS) similar to the reference product in the treatment of patients with HER2-positive early breast cancer. Two-year results from a phase III comparison confirmed the similar efficacy and safety that was apparent at 1 year.

In addition, breast pCR was similar between CT-P6 and reference trastuzumab (51.6% vs 55.1%, respectively) and for pCR without ductal carcinoma in situ (39.9% vs 41.4%).
