Polycystic Ovary Syndrome - Improving Outcomes

Polycystic ovary syndrome affects a striking 9-18% of Australian reproductive aged women and has been associated with a number of metabolic abnormalities.

Given the strong correlation between metabolic abnormalities and increased sympathetic activity, we hypothesise that reducing this activity using medication (moxonidine) can help improve the metabolic abnormalities, and therefore improve outcomes in polycystic ovary syndrome.

Condition Intervention Phase
Polycystic Ovary Syndrome Drug: Moxonidine Drug: Placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Polycystic Ovary Syndrome - Targeting the Sympathetic Nervous System to Improve Outcomes

Further study details as provided by Markus Schlaich, Baker IDI Heart and Diabetes Institute:

Primary Outcome Measures:
  • Microneurography [ Time Frame: 3 months ]
    Microneurography is a technique developed to measure the sympathetic activitiy directly from the peroneal nerve. Microneurography will be performed at baseline visit and at 3 months follow up visit.

Secondary Outcome Measures:
  • Blood biochemistry measurement [ Time Frame: 3 months ]
    To assess the metabolic function of the participants we will be drawing fasting blood samples for biochemical analysis. These test will be performed at baseline and 3 months follow up visit

  • Oral glucose tolerance test [ Time Frame: 3 months ]
    A standard 75g glucose tolerance test will be performed. Venous blood will be taken before and 2 hours after the glucose drink was given.
