Adjuvant Study of Pyrotinib in HER-2 Positive Breast Cancer

• Status: Not yet recruiting
• Trial end date: 2028-08-01
• Target enrollment: 0
• Participant gender: Female

Summary

This is a prospective, randomised, multicenter, no placebo-controlled, open label study for evaluating the efficacy and safety of pyrotinib in women with residual invasive HER2-positive breast cancer after neoadjuvant chemotherapy plus anti-HER2 target therapy. The main purpose is to investigate whether pyrotinib can further reduce the risk of recurrence from previously diagnosed HER-2 positive breast cancer based on the 1-year trastuzumab standard adjuvant treatment with or without pertuzumab.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No
