Breast Cancer
Phase 3
ShortStop HER2 Duration Study
This phase 3 study tests whether people with early HER2-positive breast cancer who have no invasive cancer left after pre-surgery chemotherapy (a pathologic complete response) can safely get a shorter course of HER2-targeted therapy. Participants are randomly assigned to receive trastuzumab (with or without pertuzumab, based on their doctor's choice) for either about 6 months or about 12 months given every three weeks by IV or as a subcutaneous shot. The trial looks mainly at whether cancer recurrence-free survival with 6 months is no worse than with 12 months. It also compares patient-reported quality of life and side effects, and tracks serious side effects, overall survival, and time to brain recurrence. Patients have heart checks and routine imaging during treatment. After treatment, people are followed every 6 months for 5 years, then yearly up to 10 years total.
