- Registration Number
- NCT03380091
- Lead Sponsor
- University of California, San Francisco
- Brief Summary
Open-label randomized clinical trial assessing the efficacy of Metformin versus Vitamin D in improving symptoms of depressed mood in polycystic ovary syndrome.
- Detailed Description
This is a single center, open-label, randomized, pilot clinical trial. Women with polycystic ovary syndrome and depressed mood, who are insulin resistant and vitamin D insufficient are eligible. Subjects are randomly assigned to one of two interventions: Vitamin D versus metformin. Subjects are followed with questionnaires and a final wrap-up clinic visit with a physician. The study duration is 12 weeks.

- Primary Outcome Measures
Name Time Method Change From Baseline in Depression Score on the Beck Depression Inventory (BDI-II) at 12 Weeks Baseline & 12 weeks BDI-II is a validated self-reported instrument of 21 questions which are each scored 0-3. Total scores range from 0-63, with higher score totals indicating more severe depression symptoms. {0-9: indicates minimal depression; 0-18: indicates mild depression; 19-29: indicates moderate depression; 30-63: indicates severe depression}. Change = Week 12 total score - Baseline week score
- Secondary Outcome Measures
Name Time Method Changes From Baseline Week in Insulin Resistance Score at Week 12. Baseline week & week 12 Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) will be used to calculate Insulin Resistance based on fasting glucose (mg/dL) and fasting insulin (μIU/mL) blood serum assays tested at Quest Diagnostics. HOMA-IR = Fasting Insulin (uIU/mL) x Fasting Glucose (mg/dL). Healthy range is between 0.5-1.4. Values below 1.0 indicate insulin sensitivity and are optimal. Values greater than 1.9 indicate clinically significant insulin resistance.
Change From Baseline in State-Trait Anxiety Inventory Score (STAI-S) at 12 Weeks Baseline week & Week 12 STAI-S is a validated self-reported instrument of 20 questions. Range of scores for the State Anxiety (STAI-S) subtest is 20-80, the higher score indicating greater anxiety. A threshold point score of 39-40 has been suggested by recent literature to detect clinically significant symptoms. Change = Week 12 total score - Baseline week score
Changes From Baseline Week in Vitamin D 25-hydroxy Levels at Week 12. Baseline week & week 12 Vitamin D, 25-hydroxy blood serum assays will be tested at Quest Diagnostics. Changes in values from baseline week to week 12 will be calculated.
