Open-label, Phase II, Study of Everolimus Plus Letrozole in Postmenopausal Women With ER+, HER2- Metastatic or Locally Advanced Breast Cancer

Status:
Completed
Trial end date:
2021-01-13
Target enrollment:
0
Participant gender:
Female
Summary
The purpose of this study is to find out if combining everolimus with letrozole is safe and has beneficial effects in postmenopausal women who have estrogen positive HER2 negative locally advanced or metastatic breast cancer. Additionally, this study aims to find out if everolimus plus exemestane is safe and has beneficial effects in women with estrogen positive locally advanced or metastatic breast cancer after treatment with everolimus plus letrozole. This study will also aim to find out if a mouth rinse can help reduce the severity of oral stomatitis, a common side effect of everolimus. This part of the study will be conducted only in countries where an alcohol free 0.5mg/5ml dexamethasone oral solution is commercially available.
