Arm A
Metformin dose of 500 mg twice a day After one week, increase dose of metformin to 1000 mg as the first dose of the day and 500 mg as the second dose. After another week, increase to 1000 mg of metformin two times a day. Metformin tx initiated 1 week before beginning chemotherapy, chemotherapy not delayed for metformin loading. Paclitaxel: 200 mg/m² IV over 3 hours, day 1 of each cycle. Paclitaxel + Carboplatin + Bevacizumab will be administered once every 21 days (Day 1) for up to 6 cycles. If subject has complete response, partial response, stable disease, or unacceptable toxicity. Bevacizumab with Metformin (Arm A) or Bevacizumab alone (Arm B) may continue as maintenance therapy. Carboplatin: Carboplatin is administered at AUC= 6 mg/ml X min IV over 15-30 minutes, immediately following Paclitaxel infusion every 21 days Bevacizumab: 15 mg/kg every 21 days, every 21 days until PD

If subject has complete response, partial response, stable disease, or unacceptable toxicity. Bevacizumab with Metformin (Arm A) or Bevacizumab alone (Arm B) may continue as maintenance therapy Bevacizumab: All patients will receive the drug at 15 mg/kg every 21 days, given immediately after completion of chemotherapy, starting with Cycle 1. After induction chemotherapy is completed (4 cycles), bevacizumab will continue at 15 mg/kg every 21 days until PD (provided neither PD nor toxicity requiring discontinuation has occurred) measured from date of first dose of bevacizumab.
