Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 42 years
  • Women only
  • No healthy volunteers
  • Adult

Study population: Women will be recruited from the multi-physician Yale Reproductive Endocrinology clinical practice and Yale Fertility Center. Metformin is a routinely employed therapeutic strategy utilized for managing PCOS by practitioners at YFC. Almost 1/3 of the patients with PCOS are not interested in pursuing fertility in the immediate future and it is these patients who will be offered participation in the trial.

Who may be able to join

  • Premenopausal between 18-42 years of age
  • Diagnosed with PCOS as defined by chronic oligo- or amenorrhea (8 menstrual periods annually); biochemical hyperandrogenemia (elevated total or free testosterone) and /or clinical hyperandrogenism (excessive facial hair \&/or acne); exclusion of common medical disorders (normal thyroid function tests and serum prolactin and exclusion of 21-hydroxylase deficiency by a fasting 17-hydroxyprogesterone <200 ng/dl).
  • Acceptable health on the basis of interview, medical history, physical examination, and laboratory tests (CBC, SMA20, urinalysis) performed within the past 6 months
  • Able to provide signed informed consent
  • Able to comply with study requirements
  • Willing to delay the start of clinically prescribed metformin treatment

Who cannot join

  • Known diabetics or those with clinically significant and known pulmonary, cardiac, renal, hepatic, neurologic, psychiatric, infectious, neoplastic and malignant disease (other than non-melanoma skin cancer)
  • Current use of hormonal contraceptives
  • Seeking pregnancy; use of fertility drugs within 6 months of study
  • Current or recent (within 3 months) use of metformin
  • Ingestion of any investigational drug within two months prior to study onset
  • Evidence of endometrial hyperplasia or cancer upon baseline EMBx

About this study

The investigators aim is to conduct a prospective un-blinded pilot study of premenopausal women diagnosed with Polycystic Ovarian Syndrome (PCOS), defined using criteria developed at the 1990 NICHD conference on PCOS, undergoing treatment for ovulation induction with Metformin. We propose that improving insulin sensitivity with use of Metformin in women diagnosed with PCOS has facilitatory influences on the uterine endometrium.

Read the detailed description

Endometrial assessments are proposed following three month and then nine month treatment with metformin; expression of specified markers at respective time points will be compared to baseline.

Visit 1: Screening

  • Signed informed consent
  • Comprehensive history intake
  • Physical exam: Vital signs, height, weight, waist circumferences, waist : hip ratio
  • Urine pregnancy test
  • Subjects provided with a 10 day supply of vaginal progesterone and EMBx will be scheduled between days 6-8 of progesterone use.

Visit 2: Baseline

  • Urine pregnancy test
  • Endometrium thickness will be measured via transvaginal ultrasound
  • EMBx: sample of endometrial tissue will be sent for histopathology to rule out endometrial hyperplasia or cancer
  • 20cc blood
  • Metformin prescription and dispensing will be as per clinical care.
  • Women will be advised to use barrier method of contraception (ie; condoms, contraceptive jellies or foam, sponge, diaphragm, or cervical cap) for the duration of the study.

Visits 3 and 5 (Weeks 8-10 and 30-34, respectively)

  • Urine pregnancy test
  • A 10 day course of vaginal progesterone to allow scheduling of EMBx's time points specified under visit 1

Visits 4 and 6 (Weeks 12 ± 1 week and 36 ± 1 week respectively)

  • The procedure specified for baseline (Visit 2) will be repeated.
Being tested
Endometrin (progesterone 100mg vaginal inserts), Metformin

What is being measured

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

  1. It is anticipated that endometrial expression of implantation markers will be upregulated by metformin treatment compared to baseline and improved parameters will be identified with longer duration of metformin exposure. endometrium biopsy

    Measured: baseline

  2. It is anticipated that endometrial expression of implantation markers will be upregulated by metformin treatment compared to baseline and improved parameters will be identified with longer duration of metformin exposure. endometrium biopsy

    Measured: 3 months

  3. It is anticipated that endometrial expression of implantation markers will be upregulated by metformin treatment compared to baseline and improved parameters will be identified with longer duration of metformin exposure. endometrium biopsy

    Measured: 9 months

Secondary outcomes (2)
  1. blood draw (20mL)

    Measured: on day of EMBx

  2. A combination of quantitative real time PCR, immunohistochemistry, and Western Blot techniques will be utilized for studying endometrial markers of receptivity in the endometrial tissue

    Measured: 9 months

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

It is anticipated that endometrial expression of implantation markers will be upregulated by metformin treatment compared to baseline and improved parameters will be identified with longer duration of metformin exposure. endometrium biopsy (time frame: baseline). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.
