(RESTORE)

View original scientific description
Girls and women 12-35 years old with obesity and polycystic ovarian syndrome who are on or off metformin, will receive a glucagon like peptide-1 receptor agonist intervention for 10 months to induce metabolic changes, weight loss and improve reproductive abnormalities.
Interventions
DRUG
Semaglutide Injectable Product (Wegovy and/or Ozempic)
10 months of semaglutide, with dose escalation as recommended by manufacturer. Maximum dose used will be 1.7mg
Primary outcome measures
Change in ovulation frequency before and after semaglutide in females with PCOS
Time frame: 14 months
The change in ovulation will be measured at baseline and 6-10 months post treatment with semaglutide from 4 months daily urinary progesterone metabolites
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Ages 12-35 years
- Sedentary- less than 2 hours of moderate (jogging, swimming etc.) exercise a week.
- Oligomenorrhea, on or off metformin, as defined per age category in the most recent 2018 PCOS international guidelines
- Initial BMI based on age and weight:
- If \<18 years, initial BMI percentile ≥95
- If 18-35 years, initial BMI ≥30 kg/m2 OR initial BMI ≥27 kg/m2 with at least one weight-related comorbid condition, e.g., hypertension or dyslipidemia
- Must be weight stable within ±5kg in the 3 months prior to enrollment
- Diagnosed with PCOS per the most stringent NIH criteria with adaptation for adolescents (oligomenorrhea \>24 months post-menarche or primary amenorrhea after age 15 years and clinical/ biochemical hypertestosteronemia
- Participants cannot be on hormonal contraception, so participants should remain abstinent or use reliable non-hormonal contraception (e.g., copper IUD) for the entire study period. For participants who receive semaglutide, they should avoid pregnancy for at least 2 months after stopping medication to avoid fetal exposure to the medication.
- For participants in the metformin + semaglutide group, participants must have been stable on ≥ 1500 mg of metformin a day for at least 3 months by time of screening
Exclusion criteria
- Diagnosed with or have a family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN2). Family history of medullary thyroid cancer or thyroid nodule palpated by endocrinologist at screening. - Per approved drug label
- Use of medications known to affect insulin sensitivity: metformin (cannot have been used in the 3 months prior to screening for the untreated arm of the study), chronic oral steroids, oral glucocorticoids within 10 days, atypical antipsychotics, immunosuppressant agents, HIV medications, estrogen-containing hormonal contraception (cannot have been used in the 6 months prior to screening), progesterone-containing hormonal contraception (cannot have been used in the 3 months prior to screening). Dermal patch or vaginal ring contraception methods. Weight loss medications or stimulants. Use of other products containing other GLP-1 agonists.
- Weight loss medications in the last 6 months
- Currently pregnant or breastfeeding women. Development of pregnancy during the study period will necessitate withdrawal from the study.
- Severe illness requiring hospitalization within 60 days.
- Diabetes, defined as Hemoglobin A1C ≥6.5%
- Anemia, defined as Hemoglobin \< 12 mg/dL
- Diagnosed major psychiatric or developmental disorder limiting informed consent. 10\) Known liver disease other than NAFLD, or AST or ALT \>125 IU/L. 11) Personal history of pancreatitis 12) Known renal disease of any severity or an eGFR at screening of \<45ml/min/1.73m2 13) History of severe GI disease (e.g., gastroparesis) 14) History of gallstones 15) Untreated thyroid disease 16) History of hypersensitivity to semaglutide 17) Other causes of hyperandrogenism (example: tumor, CAH) or amenorrhea (untreated thyroid disease, tumor, primary ovarian failure, prolactinoma). 18\) Active symptoms or undergoing treatment for anorexia nervosa or binging/purging disorder 19) Desiring pregnancy in the next 12-18 months. 20) Bariatric surgery 21) Use of THC (smoking or edible) more than 3 days a week 22) Alcohol use-drinking more than 2 drinks, more than 3 days a week 23) Any potential participants who cannot/will not commit to abstinence, use of a copper intrauterine device (IUD), or use of double barrier forms of contraception.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
