Randomized Clinical Trial to Evaluate The Effect of Metformin-GLP-1 Receptor Agonist Versus Oral Contraceptive (OC) Therapy on Reproductive Disorders and Cardiovascular Risks in Overweight Polycystic Ovarian Syndrome (PCOS) Patients
Phase: PHASE4
Conditions: Polycystic Ovary Syndrome (PCOS), Overweight, Obesity
Sponsor: Xinqiao Hospital of Chongqing

Abstract: Polycystic ovarian syndrome (PCOS) is one of the common endocrine diseases that lead to female
reproductive dysfunction. Up to 75% of PCOS patients have endocrine and metabolic abnormalities such as obesity,
hyperinsulinemia and hyperandrogenemia. As a classic PCOS drug, CPA/EE is mainly used to adjust estrogen and
progesterone levels and menstrual cycle. Recent studies have found that this drug may worsen blood lipids and
reduce insulin sensitivity. On the other hand, studies have found that reproductive disorders secondary to metabolic
disorders can be improved by correcting metabolic disorders. glucagon-like peptide1 receptor agonist (GLP-1 RA)
is a new type of glucagon-like glucagon-like peptide1 receptor agonist, which has a significant effect on the
improvement of metabolic disorders in obese patients. This topic aims to study.To observe the effects of metformin
combined with CPA/EE or GLP-1RA on blood glucose, blood lipids, sex hormone levels and menstrual cycle in
overweight PCOS patients.

The Effect of GLP-1 Agonists Versus OCs on Reproductive Disorders and
Cardiovascular Risks in Overweight PCOS

60 cases
Study design
All subjects underwent height, weight, waist and hip, hip circumference, blood
pressure, hairy score, blood biochemistry (blood routine, liver and kidney
function, electrolyte, thyroid funct ion, fasting blood glucose, glycated
hemoglobin, insulin release test, inflammatory markers, sex hormones, eight
items), gynecologic color Doppler ultrasound and glucose clamp examination
before admission. After informed consent was obtained, 1ml of the remaining
plasma was collected and frozen in the refrigerator at -80℃. Patients with
BMI≥24kg/m² or waist circumference ≥85cm were randomly assigned to GLP-
1RA+ metformin or Diane-35 + metformin. After 1 month, all subjects were
examined: height, weight, BMI, waist circumference, hip circumference, waist-to-
hip ratio, menstrual history, hirsutism score, diet, exercise frequency and
intensity, blood pressure and blood biochemistry. After 3 months, the general
condition of all subjects and general biochemical tests such as blood lipid, liver
and kidney function, fasting blood glucose, glycated hemoglobin, insulin release
test, inflammation markers and gynecological color ultrasound were tested again,
and 1ml of plasma was collected and frozen in the refrigerator at -80℃.
Trial objective
1. Provide new treatments for overweight or obese patients with PCOS.
2. Improve PCOS and establish regular menstrual cycles by reducing weight and
correcting metabolic disorders.

Inclusion and exclusion criteria
Inclusion criteria : a) clinical diagnosis of PCOS according to the Rotterdam criteria based on the
presence of two of three criteria (3) , oligomenorrhoea, clinical or biochemical hyperandrogenism, and
polycystic ovaries on ultrasound after exclusion of other endocrine causes of hyperandrogenism; b)
participants had no concurrent illness and were not on any prescription or over-the-counter medication
that was likely to affect insulin sensitivity or lipids for the preceding 12 weeks; c) participants were
advised not to change physical activity or dietary habits during the study period; d) given that all
subjects were of Asian ethnicity, overweight was defined as BMI ≥24 kg/m2. e.) all subjects had

exclusion criteria : a) age below 18 years or over 50 years; b) uncontrolled hypertension (blood
pressure ≥160/100 mmHg); c) signs of liver or renal failure or active liver disease (alanine
transaminase (ALT) > 2.5× the upper limit of normal values); d) patients who were postmenopausal
or pregnant; e) alcohol intake greater than 20 g/day; f) patients who could not complete the
intervention or had other conditions that made them ineligible for participation. For example, patients
taking glucocorticoid steroids or under treatment for a malignant tumor were excluded.

Subject benefits and possible risks
and compensate
This study is an intervention clinical observation trial. Due to the needs of the
treatment of their own diseases, the subjects need to collect venous blood for blood
sugar, insulin and other tests. After informed consent, the researchers will collect
1ml of the remaining serum, 1m of plasma and 1ml of urine after testing in the
laboratory, so as to avoid repeated blood extraction of the subjects and protect the
interests of the subjects to the greatest extent. The drugs used in the study were all
conventional treatment drugs for newly diagnosed polycystic ovary syndrome. For
the survey subjects, through baseline examination and follow-up, the drug response
of patients and the therapeutic effect of improving metabolic and reproductive
disorders can be clarified, providing a basis for the postoperative treatment of
patients and the selection of drugs for the prevention and treatment of complications.
In addition, survey subjects can also pass after 3 months.Follow-up examination to
understand the efficacy and safety of its treatment.
