Study summary

To investigate the efficacy of semaglutide in obese infertile women of childbearing age with polycystic ovary syndrome (PCOS), we design this prospective, randomized, open and controlled study. 75 obese infertile PCOS patients will be recruited and randomized into three groups: metformin, semaglutide and metformin+semaglutide, on the basis of calorie-restricted diet and physical exercise. All subjects will be treated for 12 weeks, and then stop taking the drug for at least 8 weeks to initiate ovulation induction or ovulation induction combined with artificial insemination. All subjects will be followed up for 24 weeks for pregnancy outcome. The primary endpoint of the study is the percentage of weight loss at 12 weeks of treatment. The secondary endpoints include HOMA-IR and androgen levels at 12 weeks of treatment, ovulation rate at 24 weeks of follow-up, clinical pregnancy rate and cumulative pregnancy rate, and depression, anxiety, diet and quality of life scores at 12 weeks of treatment.

  • Behavioralcalorie-restricted diet

    All subjects after randomization will be reviewed and evaluated by a nutritionist, and then will receive diet guidance. The clinical nutritionist will develop a written nutrition plan for each subject. The nutrition plan of this study adopted the method of calorie restriction diet (CRD) to develop a diet, which required 83.68 kJ/kg of energy per day, 1.2 g/kg of protein per day, 40%\~55% of carbohydrate energy supply ratio, and 20%\~30% of fat energy supply ratio, to ensure the intake of vegetables, fruits and other rich dietary fiber, and drinking more than 1.5 L per day. The nutritionist will explain the method of food exchange in detail to enrich the food types of patients. The diet diary will be distributed to each subject, and the subjects will be required to make a return visit once every four weeks, return the diet diary each time, and receive guidance according to their compliance.

  • Behavioralphysical exercise

    All subjects after randomization will be reviewed and evaluated by a trainer, and then will receive guidance of physical exercise.The trainer will formulate an exercise plan for each subject. The exercise plan consists of 30 minutes of moderate and low intensity continuous aerobic exercise every day, with a frequency of 5-7 days/week. The form of exercise can be determined according to personal hobbies, such as fast walking, jogging, climbing, swimming, etc. The exercise diary will be distributed to each subject, and the subjects are required to make a return visit once every four weeks, return the exercise diary each time, and the trainer will provide guidance to the subjects according to their compliance.

What researchers measure

Primary outcomes

  1. Percentage change in bodyweight at 12 weeks for semaglutide versus metformin

    Difference between body weight at 12 weeks and baseline divided by baseline body weight

    Time frame: at the end of 12 weeks of treatment

  2. Achievement of weight reduction of at least 5% at 12 weeks for semaglutide versus metformin

    Proportion of patients with weight loss at least 5% at 12 weeks of treatment

    Time frame: at the end of 12 weeks of treatment

Secondary outcomes

  1. HOMA-IR at 12 weeks of treatment

    compare HOMA-IR at 12 weeks of treatment among three groups

    Time frame: at the end of 12 weeks of treatment

  2. testosterone level at 12 weeks of treatment

    compare testosterone level at 12 weeks of treatment among three groups

    Time frame: at the end of 12 weeks of treatment

  3. androstenedione level at 12 weeks of treatment

    compare androstenedione level at 12 weeks of treatment among three groups

    Time frame: at the end of 12 weeks of treatment

  4. FAI (Free Androgen Index) at 12 weeks of treatment

    compare FAI at 12 weeks of treatment among three groups

    Time frame: at the end of 12 weeks of treatment

Other outcomes

  1. Depression score by self-rating depression scale (SDS)at 12 weeks of treatment

    Zung self-rating depression scale (SDS) contains 20 items. Each item is divided into four grades according to the frequency of symptoms, of which 10 are positive and 10 are negative. Positive scoring question rated as 1, 2, 3 and 4 in turn and reverse scoring questions rated as 4, 3, 2 and 1. Add all the scores to get the total rough score, and then multiply the rough score by 1.25 to get the integral part as the standard score. The lower the score, the better. According to the criteria of Chinese population, the cut-off value of SDS standard score is 53 points, of which 53-62 points is mild depression, 63-72 points is moderate depression, and more than 73 points is severe depression. SDS standard score ≥ 50 indicates depressive symptoms. Depression severity is evaluated by cumulative score of each item/80. Those below 0.5 are not depressed; 0.5-0.59 is mild depression; 0.6-0.69 is moderate to severe; more than 0.7 is severe depression.

    Time frame: at the end of 12 weeks of treatment

  2. Anxiety score by self-rating anxiety scale (SAS)at 12 weeks of treatment

    Zung self-reating anxiety scale (SAS) adopts a four-grade score, which is mainly used to assess the frequency of symptoms. The standard is: "1" means no or little time; "2" means sometimes; "3" means most of the time; "4" means most or all of the time. Of the 20 items, 15 items are stated in negative words, and scored in the order of 1-4 above. The remaining five items are stated in positive words and scored in reverse order of 4 to 1. The main statistical indicator of SAS is the total score. Add the scores of 20 items to get a rough score. Multiply the rough score by 1.25 and take the integer part to get the standard score. According to the criteria of Chinese population, the cut-off value of SAS standard score is 50 points, of which 50-59 points is mild anxiety, 60-69 points is moderate anxiety, and more than 70 points is severe anxiety.

    Time frame: at the end of 12 weeks of treatment

  3. Diet score by TFEQ-18 (three factor eating questionaire) at 12 weeks of treatment

    The Three-Factor Eating Questionnaire Revised 18-item includes three dimensions of questions: non-controlled eating (9 items), cognitive restricted eating (6 items), and emotional eating (3 items). Uncontrolled eating refers to a tendency to lose control of excessive eating when feeling hungry or stimulated by external factors. Cognitive restriction refers to consciously limiting food intake to control weight or promote weight loss. Emotional eating refers to the tendency to overeat under some negative emotional conditions. Questions 1 to 18 are scored with 1 to 4 points. The total score of the three dimensions is the total score of the scale. The higher the score of each dimension of the questionnaire, the higher the tendency of uncontrolled eating, cognitive restriction of eating and emotional eating.

    Time frame: at the end of 12 weeks of treatment

  4. Quality of life score at 12 weeks of treatment

    The World Health Organization Quality of Life (WHOQOL) - BREF can generate scores in four fields. The scale contains two independent analysis items: Q1 asks the individual's total subjective feelings about their own quality of life, and Q2 asks the individual's total subjective feelings about their own health status. The domain score is positive (that is, the higher the score, the better the quality of life). The domain score is obtained by calculating the average score of the items to which it belongs and multiplying by 4.

    Time frame: at the end of 12 weeks of treatment

  5. Ovulation rate at 24 weeks of follow-up after the end of treatment

    Number of patients with ovulation after natural and ovulation induction treatment/total number of patients

    Time frame: at the end of 24 weeks of follow-up after the end of treatment

  6. Clinical pregnancy rate at 24 weeks of follow-up after the end of treatment

    Clinical pregnancy rate=clinical pregnancy cycles/transplantation cycles

    Time frame: at the end of 24 weeks of follow-up after the end of treatment

  7. Cumulative pregnancy rate at 24 weeks of follow-up after the end of treatment

    Cumulative pregnancy rate=number of all pregnant patients/total number of patients

    Time frame: at the end of 24 weeks of follow-up after the end of treatment
