Raising Insulin Sensitivity in Post Menopause (RISE)

Brief Summary:

The purpose of this study is to find out if a novel drug approved by the Food and Drug Administration [Duavee™, Pfizer, Inc] for treatment of postmenopausal symptoms (vaginal dryness and hot flashes) and prevention of osteoporosis also improves insulin sensitivity by decreasing body fat especially in your liver.

DUAVEE™ (Conjugated Estrogens/Bazedoxifene) is a new prescription medicine that contains a mixture of estrogen (the main female hormone made by the ovaries) and bazedoxifene, which is FDA approved. For over 60 years, estrogens have been used as hormonal treatments to help manage hot flashes and help prevent postmenopausal bone loss. But in the treatment of postmenopausal women, the use of estrogens alone can increase the risk of developing cancer of the uterus. So estrogens have been traditionally paired with a progestin to decrease the risk of hyperplasia (the thickening of the lining of the uterus), which can be a precursor to cancer. DUAVEE™ uses bazedoxifene, a selective estrogen receptor modulator (SERM), in place of a progestin to help protect the uterus against thickening of the uterus that may result from estrogens alone.

In this study, you will get either DUAVEE™ or the placebo (a "dummy pill" that may look like medicine but contains no active medication) first and then switch to the other pill.

Primary Outcome Measures :
  1. 2-step hyperinsulinemic clamp at 90 mg/dl glucose with resting metabolic rate measure [ Time Frame: 8 weeks ]
    Insulin sensitivity by a 2-step hyperinsulinemic euglycemic clamp performed at the end of the two 8-week treatment periods.

Secondary Outcome Measures :
  1. Metabolic rate [ Time Frame: 8 weeks ]
    Metabolic rate step, O2 consumption and CO2 production will be measured by indirect calorimetry for 40 min (last 30 min will be used for calculations) using a metabolic cart (DeltaTrac, SensorMedics,Yorba Linda, CA). Participants will void before the test, and urine will be collected to determine urinary nitrogen and substrate oxidation.

  2. Body Composition [ Time Frame: 8 weeks ]
    DXA and MRS scans will be used for measuring body composition
