Randomized, Double-Blind, Placebo-Controlled Phase II Trial of Fulvestrant (Faslodex) Plus Everolimus in Post-Menopausal Patients With Hormone-Receptor Positive Metastatic Breast Cancer Resistant to Aromatase Inhibitor Therapy
In Brief
A Phase 2 clinical trial evaluating Fulvestrant, Everolimus, and 1 other intervention for Metastatic Breast Cancer. Completed, enrolled 131 participants across 25 sites.
Detailed Summary
Post-menopausal women with hormone-receptor positive (HR+) metastatic breast cancer resistant to aromatase inhibitor (AI) therapy will be randomized to receive Fulvestrant (Faslodex) with Everolimus or Fulvestrant (Faslodex) with a placebo (no active ingredients). Fulvestrant has demonstrated activity when used as first, second, or third line endocrine therapy, making it an attractive therapy for combination with other agents. In addition, it is commonly reserved for use following disease progression on AI therapy. Everolimus is an orally administered drug that blocks a signaling pathway called "mTOR". "mTOR" acts as a regulator for many processes in the body, including cell growth. Blocking this pathway may have an effect on cell growth. The combination of a novel class of agents (mTOR inhibitors) and an established standard treatment for metastatic HR+ breast cancer may potentially increase the clinical benefit by targeting multiple different biological pathways.

Timeline
Interventions
Fulvestrant 500 mg Day 1 \& 15 of Cycle 1, then 500 mg Day 1 of all subsequent cycles (every 28 days for 12 cycles). If no evidence of disease progression after 12 cycles, unblind and continue same dose and schedule until progression or unacceptable toxicity.
Everolimus 10 mg (2 tablets) daily x 12 cycles. If no evidence of disease progression after 12 cycles, unblind and continue same dose and schedule until progression or unacceptable toxicity.
Placebo for Everolimus (2 tablets) daily x 12 cycles. Placebo manufactured to mimic everolimus tablet.
