HOPE: Olaparib, Palbociclib and Fulvestrant for BRCA-Associated, ER/PR-Positive, Her2-Negative Metastatic Breast Cancer
About the Study
The goal of this study is to find the best dose and measure side effects of palbociclib when given together with olaparib and fulvestrant, in treating people with hormone receptor-positive (HR+), HER2-negative metastatic breast cancer who have a BRCA1 or BRCA2 mutation. Palbociclib and Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Fulvestrant is a type of treatment that may prevent breast cancer cell growth by blocking estrogen and progesterone receptor stimulation.
Type of Study
Phase I of this study is a non-randomized, dose-escalation study to find the ideal dose of Palbociclib.
Phase II study is non-randomized study where participants will receive the dose of Palbociclib determined by Phase 1.
What the Study Entails
Patients enrolled in Phase 1 will receive:
- Olaparib 300 mg by mouth twice a day, days 1-28
- Fulvestrant 500 mg intramuscularly, Day 1 + 500 mg intramuscularly Cycle 0 Day 15
- Palbociclib by mouth, days 1-21 on a 28-day cycle (dose will be determined by dose-escalation schedule)
Treatment will continue until disease progression, unacceptable toxicity, or withdrawal of consent.
Study participants will be followed for an estimated average of 7 months.
