Plain English Summary
Background and study aims
Polycystic ovary syndrome with higher than normal men's type hormone (called androgenic PCOS) occurs in 10% of women in the population. There are many potential causes. There is no durable treatment that deals with women's four main concerns: weight loss, regular cycles, fertility and hirsutism/acne and signs of high men's type hormones. The current treatment is combined hormonal contraception (The Pill) which results in some improvement but not all can take it and the benefits wear off after 6 months from stopping. The aim of this study is to perform a feasibility study of cyclic progesterone (given for 14 days to be similar to following egg release in a normal cycle) and spironolactone (a hormone that blocks men's hormone actions) over six cycles.
Who can participate?
Women or non-binary born female with physician-diagnosed androgenic PCOS, aged 19-40 years, living in Metro Vancouver, who do not have diabetes
What does the study involve?
Participants are treated with cyclic progesterone and spironolactone for 6 months. The primary outcome of the study is a change in the PCOS-specific quality of life. The researchers will assess safety with potassium measurements at the end of the study, and observe whether cyclic progesterone prevents spironolactone-related abnormal bleeding. The researchers will obtain women's reactions to taking these medicines. Participants will have two blood tests, collect first-morning saliva on 9 different days (stored in a home freezer), keep a daily menstrual cycle diary for 2 weeks on no treatment and for about 6 months on treatment, and answer questionnaires.
What are the possible benefits and risks of participating?
The benefits of participating are helping discover new treatments for PCOS, free access to cyclic progesterone (that is costly in Canada) and spironolactone, learning about yourself through diary-keeping, learning your own lab results, learning the results of the whole study (eventually). The researchers will also provide a free menstrual cup if interested (DivaCup), and the Prior book, Estrogen's Storm Season - stories of perimenopause. The risks of participating are a possible adverse reaction to either study medicine, an elevated potassium value from spironolactone, and abnormal bleeding from spironolactone. The researchers will avoid the risk of pregnancy on spironolactone by providing condoms and vaginal spermicide for women sexually active with a man.

| Scientific title | Phase II 6-month cyclic progesterone/spironolactone pilot therapy trial in polycystic ovary syndrome: pre-post, single-arm feasibility study |
| Study acronym | Cyclic P4/Sp in PCOS |
| Study hypothesis | Cyclic progesterone and spironolactone treatment over 6 months in women with androgenic polycystic ovary syndrome will significantly improve within-woman quality of life measured using the specific, validated PCOS-Q Health-Related Quality of Life instrument. |
| Ethics approval(s) | Approved 25/01/2020, Clinical Research Ethics Board of the University of British Columbia (UBC CREB Office, Room 210, Research Pavilion, 828 West 10th Avenue, Vancouver, BC V5Z 1L8, Canada; Tel: not available; pia.ganz@ors.ubc.ca), ref: H20-02824 |
| Condition | Polycystic ovary syndrome (PCOS) |
| Intervention | This is a prospective, open-label, single-arm, pragmatic interventional feasibility study in premenopausal women without type 2 diabetes mellitus (off combined hormonal contraceptives and/or metformin for 1 month) with physician-diagnosed androgenic PCOS treated with oral micronized progesterone (biochemically the same as endogenous ovarian progesterone) for 14 days/month or menstrual cycle, at a dose of 300 mg at bedtime (CyclicP4). After the first full menstrual cycle on CyclicP4 (to avoid abnormal vaginal bleeding) the researchers will begin treating with the androgen- and mineralocorticoid-receptor blocker, spironolactone, at a dose of 200 mg at bedtime taken daily for 5 months. |

| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | Progesterone, spironolactone |
| Primary outcome measure | Health-related quality of life (HRQoL) change is measured within-woman with androgenic PCOS by the PCOS-Questionnaire© (PCOS-Q) instrument comparing the total score, and domain-specific scores between Phase 0 (screening, random cycle day) and the early follicular phase of Cycle 7 (study end) after 6-months’ treatment with cyclic progesterone (CyclicP4) and 5-months’ treatment with spironolactone (Sp) therapies |
| Secondary outcome measures | Current secondary outcome measures as of 29/12/2021: 1. Serum luteinizing hormone (LH) measured by conventional laboratory methods and salivary free testosterone (FreeT) measured by liquid chromatography/mass spectroscopy (LC/MS-MS) in a quantitative aliquot (derived from three separate mornings’ samples) given the pulsatility of hormones in saliva) changes are compared within-woman between Phase 0 and Cycle 7 2. Salivary FreeT change measured by liquid chromatography/mass spectroscopy (LC/MS-MS) is compared within-woman between Phase 0 and Cycle 1 early follicular phase after 14 days of CyclicP4 taken in late Phase 0 to bring on menstruation 3. Weight (kg, measured using balance beam), height (m, measured using weight scale stadiometer), waist circumference (cm, measured using NIH method), blood pressure (seated, automated mean of three readings), body mass index (kg/m²), blood HbA1c (measured using standard laboratory methods), tobacco and alcohol use measured using CaMos questionnaire, and physical activity changes within-woman assessed between Cycle 1 and Cycle 7 4. Menstrual cycle lengths, variability (predictability), flow (assessed by counts of soaked standard-sized pad/tampons or by menstrual cup semi-quantitative measures) and Menstrual Cycle Diary© (Diary) experience changes recorded within-woman are compared between Phase 0 data and the mean of experiences from Cycles 1-6, and also compared between Phase 0 and Cycle 6 5. Estradiol, progesterone, cortisol and DHEA saliva data within-woman changes measured using high-throughput liquid chromatography-tandem mass spectrometry from Phase 0 to Cycle 1 (after one 14-day CyclicP4 exposure) and from Phase 0 to Cycle 7 6. Women’s Perceived Change questionnaire on acne and sleep quality, scored on a Likert Scale (-5 to 0 to +5), assessed in the follicular phase of Cycle 7 7. Generic HRQoL changes assessed within-woman using the SF-36 instrument domain scores and mental and physical summary scores from Phase 0 to Cycle 7 8. SF-36 HRQoL domain and summary scores at Phase 0, and also at Cycle 7, are compared with most recent SF-36 data in age- and BMI range-similar local population-based women from the regional population-based BC Canadian Multicentre Osteoporosis Study (CaMos) cohort. 9. Serum C-reactive protein (hsCRP) and albumin (assessing inflammation) by local laboratory methods, Leukocyte Telomere Length (LTL) and mitochondrial DNA copy number (assessments of genetic aging, by UBC Cote lab-specific methods), and Anti-Mullerian Hormone (AMH, assessment of reproductive reserve) by the best method available (in archived serum stored at -70°C) in 2022-2023 changes will be measured and compared within-woman from Phase 0 to Cycle 7 10. Diary Phase 0, and also Cycle 6 records will be compared with similar-aged normative premenopausal data (archived from the 1-year Prospective Ovulation Cohort, n=53, Prior NEJM 1990) using non-parametric methods and principal components analysis 11. Changes within-woman in all measures between Phase 0 and Cycle 7 will be assessed using regression methods for an influence related to how long (in months, up to 1-year) since women in this trial stopped taking combined hormonal contraceptives (CHC) or metformin treatments 12. Serum potassium (K+) measured by standard laboratory methods at Cycle 7 and determined to be, or not be, within or less than 10% above the local laboratory reference range 13. Potential adverse effects of Sp assessed using the presence/absence of abnormal/unpredictable menstrual timing and flow in Cycle 2 14. Women’s willingness to continue taking CyclicP4/Sp therapy assessed using a 7-part Likert scale at Cycle 7; women’s preference assessed on a 7-part Likert scale for CHC vs CyclicP4/Sp therapy in women who had previously taken CHC as a PCOS treatment _____ Previous secondary outcome measures: 1.
