| Purpose: |
|
RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different
ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and
help kill them or carry tumor-killing substances to them. Everolimus may stop the growth of
tumor cells by blocking some of the enzymes needed for cell growth. Bevacizumab and
everolimus may also stop the growth of tumor cells by blocking blood flow to the tumor. It
is not yet known whether bevacizumab is more effective when given together with or without
everolimus in treating ovarian epithelial cancer, fallopian tube cancer, or primary
peritoneal cancer.
PURPOSE: This randomized phase II trial is studying bevacizumab to see how well it works
when given with or without everolimus in treating patients with recurrent or persistent
ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer.

| Study Summary: |
|
OBJECTIVES:
Primary
- To compare the progression-free survival hazard ratio in patients with persistent or
recurrent ovarian epithelial, fallopian tube, or primary peritoneal cancer treated with
bevacizumab with vs without everolimus.
Secondary
- To determine the nature and degree of toxicity of these regimens.
- To compare the progression-free and overall survival of patients with measurable
disease vs those with detectable (non-measurable) disease.
- To estimate the proportion of patients with measurable disease who have objective tumor
response to treatment.
- To provide descriptive information about CA-125 response by regimen and, where
possible, by objective tumor response.
OUTLINE: This is a multicenter study. Patients are stratified according to their
platinum-free interval (≤ 182 days vs > 182 days), measurable disease status (measurable vs
non-measurable or "detectable" disease), and prior treatment with bevacizumab/aflibercept
(no vs yes). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive bevacizumab IV over 30-90 minutes on days 1 and 15 and oral
everolimus once daily on days 1-28.
- Arm II: Patients receive bevacizumab as in arm I and oral placebo once daily on days
1-28.
In both arms, courses repeat every 28 days in the absence of disease progression or
unacceptable toxicity.
After completion of study treatment, patients are followed every 3 months for 2 years and
then every 6 months for 3 years.
