NCT06852365

Brief Summary

This study will enroll women with PCOS to study the effects of first line therapy, oral contraceptive pills, and then either 12 weeks of resistant starch or 12 weeks of placebo to explore if resistant starch improves cardiometabolic parameters or impacts gut dysbiosis compared to placebo.

Eligibility Criteria

Age18 Years - 40 Years
Sexfemale(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Women between ages of 18-40 years with BMI greater than or equal to 25 kg/m² to less than or equal to 48 kg/m² diagnosed with PCOS defined by the Rotterdam criteria based on a history of chronic anovulation (8 or fewer periods), androgen excess \[defined as total serum testosterone, free testosterone or a FAI greater than or equal to 90% of the upper limit of normal) or hirsutism (Ferriman-Gallwey score greater than 6 for Hispanics/ Black and greater than or equal to 2 for women of Asian descent)\] and polycystic ovaries as defined by a pelvic ultrasound (20 or more follicles or ovarian vol greater than 10cm3) or elevated AMH.
  • For women with more regular bleeding patterns, but who are suspected to be experiencing periodic anovulatory bleeding, a midluteal progesterone (P4) level less than 3ng/dL will be evidence of ovulatory dysfunction and qualify as anovulation.
  • Women with only hyperandrogenic PCOS phenotype (hyperandrogenism + one more criteria) will be included to decrease the heterogeneity of the cohort and as metabolic risks are increased in these women compared to normo-androgenic women with PCOS.
  • Subjects should be willing to avoid pregnancy for the entire duration of the study.

You may not qualify if:

  • Subjects with other causes for irregular menses such as pregnancy, lactation, untreated hypothyroidism, untreated hyperprolactinemia and premature menopause.
  • Subjects with late onset adrenal hyperplasia
  • Subjects with history of bariatric surgery
  • Those who are unable to comply with the study procedures, for instance due to mental illness, substance abuse, or participation in other studies.
  • Subjects taking medications that affect weight or metabolic parameters (e.g. lipid lowering medications).
  • History of Crohn's disease and ulcerative colitis as well as current use of probiotics and laxatives are excluded.
  • Subjects could not have taken antibiotics for at least 3 months prior to randomization visit.
  • Subjects with greater than 20 g/day of dietary fiber intake based on pre-screening ASA-24 survey will be excluded.
  • Subjects with medical conditions that are contraindications to use of OCP and other medical conditions such as:
  • Type 1 or 2 diabetes
  • liver disease or dysfunctional liver (AST/ALT greater than 2x normal or a total bilirubin greater than 2.5 mg/dL)
  • renal disease (BUN greater than 30 mg/dL or serum creatinine greater than 1.4 mg/dL)
  • severe anemia (hemoglobin less than 10 mg/dL)
  • alcohol abuse
  • poorly controlled hypertension
  • +4 more criteria
