A Randomized Placebo Controlled Phase II Trial of Metformin in Conjunction With Chemotherapy Followed by Metformin Maintenance Therapy in Advanced Stage Ovarian, Fallopian Tube and Primary Peritoneal Cancer

This randomized phase II trial studies how well metformin hydrochloride and combination
chemotherapy works in treating patients with stage III-IV ovarian, fallopian tube, or primary
peritoneal cancer. Drugs used in chemotherapy, such as carboplatin, paclitaxel and docetaxel,
work in different ways to stop the growth of tumor cells, either by killing the cells, by
stopping them from dividing, or by stopping them from spreading. Metformin hydrochloride may
help carboplatin, paclitaxel and docetaxel work better by making tumor cells more sensitive
to the drugs. Studying samples of blood and tissue in the laboratory from patients receiving
metformin hydrochloride may help doctors learn more about the effects of metformin
hydrochloride on cells. It may also help doctors understand how well patients respond to
treatment. Giving metformin hydrochloride together with combination chemotherapy may kill
more tumor cells.

PRIMARY OBJECTIVES:

I. To determine if the addition of metformin to standard adjuvant or neoadjuvant chemotherapy
plus extended metformin (metformin hydrochloride) beyond standard chemotherapy increases
progression free survival when compared to 6 cycles of standard chemotherapy alone in
non-diabetic subjects with stage III (with any gross residual disease) or stage IV ovarian,
primary peritoneal, or fallopian tube carcinoma.

SECONDARY OBJECTIVES:

I. To determine whether the addition of metformin to standard chemotherapy plus extended
metformin beyond standard chemotherapy increases the time to biochemical progression when
compared to chemotherapy alone.

II. To compare biochemical (cancer antigen [CA]-125) response rates in the two arms.

III. To describe and compare toxicities in the two arms. IV. To compare overall survival in
both arms.

TERTIARY OBJECTIVES:

I. To elucidate metformin's molecular mechanism of action in ovarian, fallopian tube or
primary peritoneal cancer by: determining whether metformin's anti-cancer effects are
mediated by systemic metabolic changes, a direct effect on tumor cells, or both, and testing
the metabolic and proteomic alterations induced in biospecimens from non-diabetic patients
prospectively treated with standard chemotherapy in conjunction with metformin compared to
placebo.

OUTLINE:

Patients receive a standard chemotherapy regimen at the discretion of the treating physician.
Regimens include either paclitaxel intravenously (IV) over 2-3 hours and carboplatin IV over
30-60 minutes on day 1; docetaxel IV over 1 hour on and carboplatin IV over 30-60 minutes on
day 1; or paclitaxel IV over 1 hour on days 1, 8, and 15, and carboplatin IV over 30-60
minutes on day 1. Treatment repeats every 21 days for up to 6 courses. Patients are
randomized to 1 of 2 treatment arms.

ARM I: Patients receive metformin hydrochloride orally (PO) twice daily (BID) and standard
chemotherapy regimen as above for 6 courses. Treatment for metformin hydrochloride continues
for up to 2 years in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive placebo PO BID and standard chemotherapy regimen as above for 6
courses. Treatment for placebo continues for up to 2 years in the absence of disease
progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 2 years.
