Brief Summary

Official Title: “Treatment of Hyperandrogenism vs. Insulin Resistance in Infertile PCOS Women”

Condition Keyword(s):

The goal of this three-armed randomized controlled trial is to establish the relative roles of treatment of hyperandrogenism versus obesity (as the largest modifiable factor contributing to insulin resistance) in treating infertility and improving pregnancy outcomes among obese PCOS women. We hypothesize that the key to restoring ovulation leading to live birth is to correct hyperandrogenism with oral contraceptive pills, but the key to avoiding later pregnancy complications isto improve insulin sensitivity with weight loss.

Study Type: Interventional

Detailed Clinical Trial Description

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility among women, and women with PCOS are at increased risk for pregnancy complications such as gestational diabetes and pre-eclampsia. Both hyperandrogenism (HA) and obesity exacerbated insulin resistance (IR) are characteristics of the syndrome, and are targets for treatment, but which should be the predominant focus is still unknown. Phase 1 of this study will be a randomized trial of three preconception interventions in infertile women with PCOS. The first arm will be a combined intervention of medication, meal replacements, and lifestyle modification to improve IR. Sibutramine is a combined norepinephrine-serotonin re-uptake inhibitor that is associated with increased satiation (fullness) and a resulting reduction in food intake. The second arm will be the use of a continuous OCP for 4 months to improve HA.

Lo-Estrin 1/20 will be used in a continuous method for 4 months to suppress the ovary. The third arm is the combination of both to improve HA an IR. Phase II of this study will involve ovulation induction with clomiphene citrate with hopeful outcome of pregnancy.

Finally, Phase III involve following the pregnancies for outcomes and complications.

Intervention(s) in this Clinical Trial

  • Drug: Sibutramine (Meridia) and Lifestyle Intervention with exercise and diet
    • Sibutramine will be initiated at a dose of 5 mg/day. The dose will be increased over the following visits from 5 mg/day to a maximum of 15 mg/day.
  • Drug: Loestrin 1/20
    • Patients will be started on a low dose containing OCP for a continuous 4 month period.
  • Drug: Sibutramine (Meridia) and Loestrin 1/20
    • Medications will be administered as described for Arm A and Arm B.

Arms, Groups and Cohorts in this Clinical Trial

  • Active Comparator: Phase 1, Arm A
    • Weight Loss via Medication/Meal Replacement/Lifestyle Modification
  • Active Comparator: Phase 1, Arm B
    • Reducing HA will consist of continuous low dose OCP
  • Active Comparator: Phase 1, Arm C
    • Combination of treatments from Arm A and Arm B

Outcome Measures for this Clinical Trial

Primary Measures

  • Identify the effects of weight loss vs. OCP therapy on the PCOS reproductive phenotype. Pretreatment with OCP will most improve the preconception PCOS phenotype compared to weight loss, and the combination of both will be the best.
    • Time Frame: Assessed during data analysis
      Safety Issue?: Yes

Secondary Measures

  • Compare impact of weight loss vs. OCP vs. the combination of both on the live birth rate. The live birth rate will be lowest in the weight loss group, higher in the OCP group and highest in the group treated with both.
    • Time Frame: At time of data analysis
      Safety Issue?: No

Criteria for Participation in this Clinical Trial
