Metformin Hydrochloride and Combination Chemotherapy in Treating Patients With Stage III-IV Ovarian, Fallopian Tube, or Primary Peritoneal Cancer

Overview

About this study

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.

  • ELIGIBILITY CRITERIA FOR REGISTRATION: subjects undergoing primary debulking surgery must have stage III or IV disease and have undergone surgery to include, at a minimum, removal of the uterus, ovaries and fallopian tubes; these patients may be optimally debulked (less than 1 cm residual disease) but must have grossly visible macroscopic residual disease OR be suboptimally debulked
  • ELIGIBILITY CRITERIA FOR REGISTRATION: subjects for whom neoadjuvant chemotherapy followed by interval cytoreductive surgery is planned must have fine needle aspirate (FNA) or other cytology showing adenocarcinoma OR core biopsies OR surgically directed biopsies showing adenocarcinoma AND CA125 over 250 OR CA125:CEA ratio > 25 OR CA =< 250 with no evidence of GI cancer; they should have presumed stage III or IV disease, generally based on abdominal carcinomatosis, omental caking, pleural effusions or ascites
  • ELIGIBILITY CRITERIA FOR REGISTRATION: the subject and her physician must agree to six cycles of one of the standard of care regimens allowed on this protocol; these regimens (starting dosage) include:
    • IV paclitaxel 175 mg/m^2 and carboplatin area under the curve (AUC) 5-6 every 21 days
    • IV docetaxel 75 mg/m^2 and carboplatin AUC 5-6 every 21 days
    • IV paclitaxel 80 mg/m^2 day 1, 8, and 15 and carboplatin AUC 5-6 day 1 every 21 days
      • Use of granulocyte colony stimulating factor is permitted, but additional chemotherapy agents (e.g. gemcitabine) or biologic agents (e.g. bevacizumab) are not; dose modifications for patients over age 70 are allowable as outlined in the protocol
  • ELIGIBILITY CRITERIA FOR REGISTRATION: ECOG performance status =< 2
  • ELIGIBILITY CRITERIA FOR REGISTRATION: Leukocytes >= 3,000/mcL
  • ELIGIBILITY CRITERIA FOR REGISTRATION: absolute neutrophil count >= 1,500/mcL

  • ELIGIBILITY CRITERIA FOR REGISTRATION: women of child-bearing potential must agree to use an effective method of birth control on trial, as the safety of metformin in pregnancy has not been established; an effective method of birth control includes surgical sterilization of woman or her partner, abstinence, or two barrier methods (e.g. condom plus diaphragm); hormonal methods of birth control are not permitted on this study
