Phase II Study of Weekly Paclitaxel with Trastuzumab and Pertuzumab in Patients with Human Epidermal Growth Receptor 2 Overexpressing Metastatic Breast Cancer: 5‐Year Follow‐up

Conclusion.With a longer follow‐up of almost 5 years, combination of weekly paclitaxel, trastuzumab, and pertuzumab remains effective with a favorable median PFS and a median OS not reached.Implications for Practice.The combination of weekly paclitaxel, trastuzumab, and pertuzumab has been endorsed by the National Comprehensive Cancer Network as one of the first‐line treatment options in patients with human epidermal growth receptor 2 (HER2)‐positive metastatic breast cancer (MBC). However, the long‐term safety and efficacy are still unknown. Findings from this phase II study provide favorable preliminary data on the safety and efficacy of trastuzumab and pertuzumab in combination with weekly paclitaxel at 5‐year follow‐up, and it remains an effective first‐line treatment option for patients with HER2‐positive MBC.
