Trial summary

Polycystic ovary syndrome is one of the main diseases leading to infertility in women of childbearing age. In addition to endocrine and reproductive dysfunction, it is often accompanied by significant metabolic abnormalities, which seriously affect long-term health and quality of life.

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 20 to 40 years
  • Women only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • The included population is PCOS patients who are seeking their first IVF treatment at the Reproductive Medicine Center of Peking University Third Hospital, aged 20-40 years old. PCOS diagnosis meets two of the following three criteria based on the 2003 Rotterdam criteria: clinical manifestations of oligomenorrhea and/or amenorrhea, hyperandrogenism or hyperandrogenism (hirsutism, acne, etc.), PCO like changes in the ovaries under ultrasound, while excluding diseases such as hyperprolactinemia, congenital adrenal hyperplasia, Cushing syndrome, and androgen secreting tumors. All selected subjects have no medical history of taking steroid drugs within 3 months.

Who cannot join

  • 1) Refusing to sign informed consent or unable to follow up on time; 2) Severe complications requiring cessation of treatment (>2 weeks) or termination of treatment; 3) Patients should take vitamin D orally before enrollment (baseline data still needs to be recorded for later statistical analysis); 4) Any unstable or medical condition that affects patient safety and research compliance. 5) Male partners have severe male infertility factors; 6) Patients undergoing embryo analysis using pre implantation genetic testing techniques (PGT-A/SR/M).

About this study

Official title: The Phenotype and Clinical Intervention of High Branched Chain Amino Acid Type of Polycystic Ovary Syndrome

Polycystic ovary syndrome is one of the main diseases leading to infertility in women of childbearing age. In addition to endocrine and reproductive dysfunction, it is often accompanied by significant metabolic abnormalities, which seriously affect long-term health and quality of life. Our preliminary research found that 68% of PCOS patients have significantly increased branched chain amino acid content, accompanied by a decrease in clinical pregnancy rate and an increase in miscarriage rate, which poses challenges to the diagnosis and treatment of PCOS. Based on this, we propose a new PCOS typing strategy that uses the concentration of branched chain amino acids as an evaluation indicator to diagnose high branched chain amino acid PCOS, where the serum BCAA concentration is higher than 405 μ Mol/L is diagnosed as high branched chain amino acid PCOS. According to the different degrees of elevation of branched chain amino acids, they are further divided into common type and ultra-high type, and the impact of different concentrations of branched chain amino acids on pregnancy outcomes, pregnancy complications, and newborns after assisted reproductive technology is analyzed; Based on the typical clinical and metabolic phenotypes of high branched chain amino acid type PCOS patients, corresponding intervention strategies are formulated. By analyzing the clinical pregnancy outcomes, pregnancy complications, and neonatal conditions of patients in the combination intervention group (protein restricted diet combined with vitamin D supplementation) and the conventional treatment group, safe and effective intervention methods are determined.

What is being measured

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

  1. clinical pregnancy rate

    Clinical pregnancy patients/(transplant cycle) patients × 100%

    Measured: one year

Secondary outcomes (5)
  1. Excellent embryo rate

    number of high-quality embryos/number of normal fertilized cleavage embryos × 100%

    Measured: one year

  2. Fertilization rate

    number of fertilized eggs/number of retrieved eggs × 100%

    Implantation rate=number of gestational sacs/total number of transplanted embryos × 100% (the number of gestational sacs in a single embryo transfer is only counted as 1)

    Measured: one year

  3. Early miscarriage rate

    number of natural abortion cycles within 12 weeks of pregnancy/number of clinical pregnancy cycles × 100%

    Measured: one year

  4. Live birth rate (transplant cycle)

    number of live births/number of transplant cycles × 100%

    Measured: one year

  5. The incidence of pregnancy complications

    number of pregnancy complications/number of clinical pregnancy cycles × 100%

    Measured: one year

Questions about this trial

What is this clinical trial studying?

A study testing protein restricted diet combined with vitamin D intervention in people with Polycystic Ovary Syndrome, run by Peking University Third Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 5 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

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?

This study is still under way. Results are not available in the source record yet.

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?

clinical pregnancy rate (time frame: one year). 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2024.
