Site for A Randomized, Double-Blind, Phase III Trial of Paclitaxel/Trastuzumab/Pertuzumab with Atezolizumab or Placebo in First-Line HER2-Positive Metastatic Breast Cancer (NRG-BR004) (PSCI# 20-136).
The purpose of this study is to compare the usual treatment plus placebo to the usual treatment plus atezolizumab. The addition of atezolizumab to the usual treatment could stabilize your cancer. This study will help the study doctors find out if this different approach is better, the same, or worse than the usual approach. To decide if it is better, the study doctors will be looking to see if the atezolizumab lengthens the time during and after the treatment of your cancer that you live with your cancer and it is stable. Atezolizumab is already approved by the FDA for use in non-small cell lung cancer and urinary cancer. Its use in this study is considered experimental. There will be about 600 people taking part in this study.
