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 | Progression free survival (PFS) evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 and Gynecological Cancer Intergroup (GCIG) criteria | Kaplan-Meier curves will be generated and the metformin and placebo groups compared using a logrank test stratified by initial treatment (primary debulking surgery or neoadjuvant therapy). A one-sided alpha level of 0.15 will be used to determine statistical significance. Median PFS and associated 90% confidence interval will be estimated using the method described in Brookmeyer and Crowley. A Cox regression model will also be fit to assess and adjust for the effects of the stratification factor and other baseline covariates (for example, age, ECOG performance status). | Time from randomization until disease progression or death from any cause, assessed up to 2 years | |
Secondary | Time to biochemical (CA-125) progression using GCIG criteria | Analyzed using Kaplan-Meier curves, stratified logrank test, and Cox regression modeling. CA-125 response rates in the subgroup of patients with elevated CA-125 at entry (i.e., > institutional ULN) will be compared between the two treatment arms using a chi-square test. | Up to 2 years | |
Secondary | Overall survival | Analyzed using Kaplan-Meier curves, stratified logrank test, and Cox regression modeling. | Up to 2 years | |
Secondary | Incidence of adverse events, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 | Adverse events will be summarized by type, grade, and attribution. Treatment group comparisons will be performed using chi-square or Fisher's exact test. | Up to 2 years |
