Summary

This was a planned early-stage trial to test a new oral drug called ERW316, alone or with hormone therapies, in people with advanced breast cancer or other solid tumors. The study aimed to find a safe dose and check for side effects. However, the trial was withdrawn before any participants were enrolled, so no results are available.
