May 30, 2023 updated by: Franck Mauvais-Jarvis, Tulane University Health Sciences Center
The goal of this pilot clinical study is to perform a randomized placebo-controlled study to assess the beneficial effect of a 3 month-treatment with Bazedoxifene/Conjugated Estrogens (BZA/CE) vs. placebo on glucose homeostasis and body composition in 20 post-menopausal women. The recruitment will be performed at Tulane Health Sciences Center.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Bazedoxifene/Conjugated Estrogens (BZA/CE)
Participants assigned to BZA/CE will receive a daily tablet containing conjugated estrogens 0.45 mg and bazedoxifene 20 mg. BZA/CE (bazedoxifene/conjugated estrogens) tablets, 0.45 mg/20 mg are oval, biconvex, pink tablets, branded with "0.45/20" in black ink on one side. The recommended and only FDA approved dosage is one BZA/CE tablet daily, taken without regard to meals. Tablets should be swallowed whole. If a dose of BZA/CE is missed, participants will be instructed to take it as soon as remembered unless it is almost time for the next scheduled dose. They should not take two doses at the same time. The dose is one tablet per day independent of weight and fat mass. Participants will be provided with information about BZA/CE and its potential side effects and contraindications.
Daily tablet containing conjugated estrogens 0.45 mg and bazedoxifene 20 mg.
Other Names:
  • DUAVEE
Placebo Comparator: Placebo
Participants assigned to placebo will receive a daily tablet that matches the BZA/CE to maintain the blind. Placebo tablets, 0.45 mg/20 mg are oval, biconvex, pink tablets, branded with "0.45/20" in black ink on one side. Also to assure the blind is maintain, participants in the placebo group will be given the same instructions for taking the study medication.Tablets should be swallowed whole. If a dose, participants will be instructed to take it as soon as remembered unless it is almost time for the next scheduled dose. They should not take two doses at the same time. The dose is one tablet per day independent of weight and fat mass. Participants will be provided with information about BZA/CE and its potential side effects and contraindications, again to maintain the blind.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Body Mass Index
Time Frame: Change at 3 months from baseline
Body composition will be assessed through change in body mass index at baseline and at 3 months post-treatment.
Change at 3 months from baseline
Effect of CE/BZA on Body Composition Using Waist-to-hip Ratio
Time Frame: Change at 3 months from baseline
Body composition will be assessed through change in waist-to-hip ratio at baseline and at 3 months post-treatment.
Change at 3 months from baseline
Change in Body Composition Using Dual-energy X-ray Absorptiometry (DXA)
Time Frame: Change at 3 months from baseline
Dual-Energy X-ray Absorptiometry was used to assess body composition. DXA uses an x-ray technique to look at the density of the body and can then estimate the amount of lean muscle mass and fat tissue. Body composition will be assessed through change in DXA body composition at baseline and at 3 months post-treatment.
Change at 3 months from baseline
Change in Acute Insulin Response to Glucose (AIRg)
Time Frame: Change at 3 months from baseline
This will be assessed through an IV Glucose Tolerance Test (IVGTT) conducted at baseline and 3 months to measure the change in acute insulin response to glucose. IVGTT data derived by MINMOD Millennium software. MINMOD: a computer program to calculate insulin sensitivity and pancreatic responsivity from the frequently sampled intravenous glucose tolerance test. Acute Insulin Response (AIRg) to Intravenous Glucose is based on glucose and insulin levels obtained during the frequently sampled intravenous glucose tolerance test and calculated using a mathematical model. AIRg is measured as the magnitude of the insulin response to an intravenous glucose injection following glucose administration. A low AIRg indicates decreased ability of the pancreas to secrete insulin.
Change at 3 months from baseline
Change in Basal Glucose Concentration (Gb)
Time Frame: Change at 3 months from baseline
This will be assessed through an IV Glucose Tolerance Test (IVGTT) conducted at baseline and 3 months to measure the change in basal glucose concentration. IVGTT data derived by MINMOD Millennium software.
Change at 3 months from baseline
Change in Disposition Index (DI)
Time Frame: Change at 3 months from baseline
Disposition index (DI) is the product of insulin sensitivity times the amount of insulin secreted in response to blood glucose levels. DI is commonly used as a measure of β-cell function. This will be assessed through an IV Glucose Tolerance Test (IVGTT) conducted at baseline and 3 months to measure the change in disposition index (DI). IVGTT data derived by MINMOD Millennium software. DI is based on glucose and insulin levels obtained during the frequently sampled intravenous glucose tolerance test and calculated using a mathematical model. DI is the product of insulin sensitivity and the amount of insulin secreted in response to blood glucose levels. Disposition index is used as a measure of beta cell function and the ability of the body to dispose of a glucose load. A low DI is indicative of a higher risk of developing diabetes.
Change at 3 months from baseline
Change in Insulin Sensitivity (SI) Index
Time Frame: Change at 3 months from baseline
SI indicates the net capacity for insulin to promote the disposal of glucose and to inhibit the endogenous production of glucose. This will be assessed through an IV Glucose Tolerance Test (IVGTT) conducted at baseline and 3 months to measure the change in insulin sensitivity (SI) index. IVGTT data derived by MINMOD Millennium software. SI is based on glucose and insulin levels obtained during the frequently sampled intravenous glucose tolerance test and calculated using a mathematical model. SI is a measure of tissue response to circulating insulin in the blood following glucose injection. A low SI signifies low insulin sensitivity and high SI represents high insulin sensitivity.
Change at 3 months from baseline
Change in Homeostatic Model Assessment (HOMA) β-cell Function
Time Frame: Change at 3 months from baseline
The homeostasis model assessment of β-cell function (HOMA-β) is an index of insulin secretory function derived from fasting plasma glucose and insulin concentrations. This will be assessed at baseline and 3 months to measure the change in Homeostatic model assessment (HOMA) β-cell function. (HOMA) β-cell function is a method used to quantify beta-cell function from fasting blood samples of insulin and glucose. Normal levels for (HOMA) β-cell function is 107 or more. Lower numbers mean higher risk of developing diabetes.
Change at 3 months from baseline
Change in Homeostatic Model Assessment (HOMA) Insulin Resistance (IR)
Time Frame: Change at 3 months from baseline
Homeostatic model assessment (HOMA) is a method for assessing β-cell function and insulin resistance (IR) from basal (fasting) glucose and insulin or C-peptide concentrations. This will be assessed at baseline and 3 months to measure the change in Homeostatic model assessment (HOMA) insulin resistance. HOMA IR is a method used to quantify insulin resistance from fasting blood samples of insulin and glucose. Normal levels for HOMA-IR is less than 2.0. Higher levels mean higher risk for developing diabetes.
Change at 3 months from baseline
Change in Fasting Insulin Clearance (FIC)
Time Frame: Change at 3 months from baseline
This will be assessed at baseline and 3 months to measure the change in fasting insulin clearance (FIC). FIC derived from fasting C-peptide to insulin ratio.
Change at 3 months from baseline
Change in Glucose-stimulated Insulin Clearance (GSIC)
Time Frame: Change at 3 months from baseline
This will be assessed through an IV Glucose Tolerance Test (IVGTT) conducted at baseline and 3 months to measure the change in glucose-stimulated insulin clearance (GSIC). GSIC derived from molar ratio of C-peptide to insulin area under curve (AUC) over first 20 min of IVGTT.
