About this study

This randomized controlled clinical trial aims to evaluate the effect of orlistat on the metabolic and hormonal features of women with polycystic ovary syndrome (PCOS). Eligible women diagnosed with PCOS according to the Rotterdam criteria will be randomly assigned to receive either orlistat plus standard lifestyle advice or placebo plus standard lifestyle advice for three months. The study will assess the effect of orlistat on hormonal parameters, glucose metabolism, lipid profile, liver function, anthropometric measures, non-alcoholic fatty liver disease, and quality of life to determine its effectiveness as an adjunctive treatment for women with PCOS.

Read the detailed description

Polycystic ovary syndrome (PCOS) is one of the most common endocrine and metabolic disorders affecting women of reproductive age and is frequently associated with obesity, insulin resistance, dyslipidemia, and hormonal imbalance. Lifestyle modification remains the cornerstone of management; however, additional therapeutic options are needed to improve metabolic and reproductive outcomes. Orlistat, a gastrointestinal lipase inhibitor, promotes weight reduction by decreasing dietary fat absorption and has demonstrated potential benefits in improving insulin resistance and lipid metabolism.

This study is a single-center, randomized controlled clinical trial to be conducted at Ayub Teaching Hospital, Abbottabad. A total of 120 women aged 18-45 years with PCOS diagnosed according to the Rotterdam criteria will be enrolled and randomly allocated in a 1:1 ratio to either the intervention group or the control group. Participants in the intervention group will receive orlistat capsules twice daily in addition to standard lifestyle advice, while participants in the control group will receive placebo together with the same lifestyle recommendations, including a healthy diet and regular physical activity. The intervention period will last three months.

Participants will undergo baseline assessment, telephone follow-up visits at one and two months to monitor treatment adherence, and a final in-person assessment after three months. The primary outcome is improvement in at least one abnormality defined by the Rotterdam diagnostic criteria. Secondary outcomes include changes in sex hormone profile (LH, FSH, LH/FSH ratio, AMH, and free testosterone), fasting glucose and insulin parameters, HbA1c, lipid profile, liver function tests, lipid accumulation product, hepatic steatosis index, ultrasound grading of non-alcoholic fatty liver disease, anthropometric measures, and PCOS-related quality of life. The findings of this study will provide evidence regarding the effectiveness of orlistat as an adjunct to lifestyle modification for improving the metabolic and hormonal manifestations of PCOS in women.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Participants will also receive standard lifestyle advice, including a healthy diet, regular physical activity, walking, and cycling.

  • PlaceboDrug

    Matching placebo capsules administered twice daily for 3 months in addition to standard lifestyle advice, including a healthy diet, regular physical activity, walking, and cycling, for women with polycystic ovary syndrome (PCOS).

  • Standard Lifestyle AdviceBehavioural

What is being measured

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

  1. Polycystic Ovary Syndrome (PCOS) Features

    Improvement in at least one baseline abnormality according to the Rotterdam Criteria, including ovulatory dysfunction, hyperandrogenism, or polycystic ovarian morphology on ultrasonography.

    Measured: Baseline and 3 months

  2. Luteinizing Hormone/Follicle Stimulating Hormone (LH/FSH) Ratio

  3. Anti-Müllerian Hormone (AMH)

    Change in serum Anti-Müllerian Hormone concentration (ng/mL) measured by laboratory assay.

    Measured: Baseline and 3 months

  4. Follicle Stimulating Hormone (FSH)

    Change in serum FSH concentration (IU/L) measured by laboratory assay

    Measured: Baseline and 3 months

  5. Luteinizing Hormone (LH)

    Change in serum LH concentration (IU/L) measured by laboratory assay.

    Measured: Baseline and 3 months

  6. Free Testosterone

    Change in serum free testosterone concentration measured by laboratory assay.

    Measured: Baseline and 3 months

  7. Fasting Blood Glucose

    Change in fasting blood glucose concentration (mg/dL) measured by laboratory assay.

    Measured: Baseline and 3 months
