NCT02635386

Brief Summary

This is a randomized, single-blind, parallel 5 treatment group 24-week trial designed to directly compare the therapeutic effects of exenatide once weekly (EQW), dapagliflozin (DAPA), EQW plus DAPA, combined DAPA/metformin extended release (XR) and the weight loss medication, phentermine/topiramate extended release (PHEN/TPM ER) on metabolic and endocrinological parameters in overweight/obese non-diabetic women with PCOS. In this study, we will examine the efficacy of these therapies on metabolic parameters, body weight and body composition, anthropometric measurements, and reproductive function in a well-defined group of pre-menopausal overweight/obese, non-diabetic women with PCOS, focusing on their relationship to insulin resistance and obesity. We hope to determine which treatment(s) addressing the multifaceted disturbances of individual subgroups emerge as the preferable therapy.

Outcome Measures

Primary Outcomes (1)

  • Oral Disposition (Insulin Sensitivity-insulin Secretion) Index

    An estimation of β-cell compensatory function, the insulin secretion-sensitivity index (IS-SI) will be derived by applying the concept of the oral disposition index to measurements obtained during the 2-h OGTT and calculated as the index of insulin secretion factored by insulin sensitivity (ΔINS/ΔPG 30 x Matsuda SIOGTT) from the OGTT. A higher score shows improved pancreatic insulin responsiveness relative to resistance.

    24 weeks of treatment

Secondary Outcomes (22)

  • Absolute Body Weight

    24 weeks of treatment

  • Body Mass Index (BMI)

    24 weeks of treatment

  • Change in Percent Body Weight

    Change from baseline (time 0) to study end (24 weeks)

  • Central Adiposity (Waist Circumference)

    24 weeks of treatment

  • Waist-to-Hip Ratio (WHR)

    24 weeks of treatment

  • +17 more secondary outcomes

Limitations and Caveats

One limitation of this study is the lack of a placebo only arm. As we were interested in the effects of different treatment regimens for obese women with PCOS, this study was designed to provide all patients with drug therapy. Limitations of the present study further include the absence of gold-standard measures of insulin sensitivity ; instead we used the OGTT using established surrogate measures.. Last, serial assessments were over only 24 weeks of treatment.
