Trial summary

PCOS occurs when a woman does not release an egg regularly each month, causing her periods to be irregular. Women with PCOS can also have increased hair growth on the face and body, acne, head balding, infertility, pre-diabetes, and diabetes. Read more about this study

About this study

Official title: Effects of Metformin on Mitochondrial Function in Polycystic Ovary Syndrome

PCOS occurs when a woman does not release an egg regularly each month, causing her periods to be irregular. Women with PCOS can also have increased hair growth on the face and body, acne, head balding, infertility, pre-diabetes, and diabetes. PCOS is commonly treated with oral contraceptive pills (also known as the birth control pills). Sometimes, a medication called metformin is also used to treat PCOS, especially if a woman has evidence of insulin resistance or if fertility is desired. Unfortunately, metformin works in only some women with PCOS. The mechanism through which metformin works in PCOS is not clear and it difficult to predict who will benefit from metformin treatment and who will not.

The investigators are doing this research study to look at how the medication metformin affects the cells in the body of patients with PCOS. Specifically, the investigators will look at how metformin affects the mitochondria. Mitochondria are the part of cells that produce fuel (energy) for other cells and play a role in metabolism. The investigators would like to see whether there is a relationship between mitochondrial activity and symptoms of polycystic ovary syndrome (PCOS) before and after treatment with metformin. They would also like to study whether genes affect the response to metformin in women with PCOS.

Read the detailed description

Women who are eligible to enroll in this study will be treated with the medication metformin for 12 weeks. Before and after treatment with metformin, the following will be assessed:

  • Weight, blood pressure, waist circumference
  • Lipids (cholesterol)
  • Hormone levels (including testosterone and other androgens)
  • IV glucose tolerance test (to assess for early evidence of insulin resistance)
  • Effect of metformin on muscle mitochondria (this will involve one MRI scan and one muscle biopsy each before and after treatment with metformin)

Ovulation will be closely monitored at least twice a month with pelvic ultrasounds and blood tests for estrogen and progesterone levels.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Muscle Metabolism/Mitochondrial Function

    The change in mitochondrial activity before and after metformin treatment will be analyzed in relationship to the clinical response to 3 months of metformin treatment (i.e., clinical response to metformin = changes in glucose metabolism, hormone levels, and ovulation response)

    Measured: 3 months

Secondary outcomes (1)
  1. Genetic risk variants affecting mitochondrial function/metabolism

    Blood will be analyzed for differences in genes between patients and its relationship to mitochondrial function.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Metformin ER in people with Polycystic Ovary Syndrome, run by Massachusetts General Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Muscle Metabolism/Mitochondrial Function (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02198417, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Aug 2018.
