      Trial Summary

      This is an open-label, dose-finding, safety, pharmacokinetics (PK), and evidence-of-activity study of GDC-0927 in postmenopausal women with locally advanced or metastatic Estrogen Receptor Positive (ER+) Human Epidermal Growth Factor Receptor 2 (HER2) breast cancer. The study will be conducted in two parts: Dose escalation and Dose expansion. During dose escalation, GDC-0927 will be administered orally as a single dose on Day -7 for PK evaluation during the lead-in period. Depending on safety and tolerability, participants will be assigned sequentially to escalating doses of GDC-0927 using standard 3+3 design. During dose expansion, there will be no PK week lead-in period. All participants will be treated until disease progression, unacceptable toxicity, participant withdrawal of consent or study termination.

      This clinical trial was done to study a new medicine called, “GDC-0927”. Researchers wanted to find out what the highest dose of GDC-0927 was that was safe for patients with ER+/HER− breast cancer. Researchers also wanted to investigate GDC-0927 doses in order to be able to recommend a safe dose that could be used in future studies. Forty-two patients took part in this study at 14 study centers in 2 countries.
