Study seeks best heart check schedule for breast cancer drug

NCT ID NCT02696707

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at 200 women with early-stage HER2-positive breast cancer who were taking trastuzumab. The goal was to compare two standard schedules for monitoring heart function: every 3 months versus every 4 months. Researchers wanted to see if less frequent monitoring could be safe and effective, since trastuzumab can sometimes cause heart damage.
