What is the purpose of this trial?

This trial aims to explore how different factors contribute to high levels of male hormones in women with Polycystic Ovary Syndrome (PCOS). It examines how the body's hormone responses and insulin levels affect this condition, especially comparing younger and older women. Participants will receive two types of hormone injections—ACTH (Adrenocorticotropic hormone) and rhCG (Recombinant Human Chorionic Gonadotropin)—to help researchers understand these effects. Women with PCOS who have irregular periods or fewer than nine periods a year may be a good fit for this study. As an Early Phase 1 trial, this research focuses on understanding how these hormone treatments work in people, offering participants a chance to contribute to groundbreaking insights.

Will I have to stop taking my current medications?

Yes, you will need to stop taking any medications that affect the reproductive system, such as birth control pills, metformin, and certain mood stabilizers, at least 2 months before screening and 3 months before the study.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that ACTH, a hormone, is generally safe for women with PCOS, as their reactions are similar to those of healthy individuals. This indicates it is usually well-tolerated. Studies also suggest that rhCG, another hormone, is well-tolerated and effective, particularly in aiding women who struggle with ovulation. Both treatments have been used safely in medical settings. However, as this trial is just beginning, the researchers are still gathering safety information. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using ACTH (Cosyntropin) and rhCG (Ovidrel) for polycystic ovary syndrome (PCOS) because these treatments work in unique ways compared to standard options like hormonal contraceptives and anti-androgens. ACTH stimulates the adrenal glands, potentially balancing hormone production, while rhCG mimics a hormone involved in reproductive processes, which might help regulate ovarian function. Unlike typical treatments that primarily manage symptoms, this combination targets underlying hormonal imbalances, offering a promising new approach for those struggling with PCOS.

What evidence suggests that this trial's treatments could be effective for PCOS?

Research has shown that ACTH, a hormone, can increase the production of adrenal hormones in women with polycystic ovary syndrome (PCOS), potentially managing symptoms caused by high levels of male hormones. In this trial, some participants will receive ACTH. Studies also suggest that rhCG, another hormone, supports ovulation and improves pregnancy rates in women with PCOS. Even small amounts of rhCG have shown promise in increasing the chances of ovulation and reducing unsuccessful treatments. Participants in this trial may receive rhCG as part of their treatment. These treatments aim to correct hormone imbalances, a major issue in PCOS. ^{1 6 7 8 9}

Published Research Related to This Trial

In a study involving 42 women with polycystic ovary syndrome (PCOS) and 42 matched healthy controls, it was found that women with PCOS had significantly higher levels of androgens across four different steroid biosynthetic pathways, indicating a complex hormonal imbalance associated with the condition.

The research revealed that while PCOS women exhibited elevated serum testosterone levels and metabolites from various androgen pathways, no specific diagnostic pattern was identified in their steroid profiles, suggesting that PCOS may not have a unique biochemical signature compared to other conditions affecting steroid biosynthesis.

The serum steroid signature of PCOS hints at the involvement of novel pathways for excess androgen biosynthesis. Altinkilic, EM., du Toit, T., Sakin, Ö., et al.[2023]

In lean women with polycystic ovary syndrome (PCOS), there is increased production of cortisol and androgens, indicating a dysregulation of steroid metabolism, which may involve enhanced activity of the enzyme 5alpha-reductase (5alpha-R) and reduced activity of 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1).

Insulin levels were found to positively correlate with the activity of 5alpha-R in PCOS, suggesting that insulin may enhance the conversion of steroids, but this was not linked to elevated cortisol production rates, indicating that the dysregulation of steroid metabolism is complex and not the primary cause of PCOS.

In a study of 12 women with polycystic ovary syndrome (PCOS), it was found that their response to corticotropin-releasing hormone (CRH) was significantly greater than that of age- and weight-matched controls, indicating a heightened adrenal response.

The prolonged secretion of ACTH and cortisol in PCOS patients suggests a hyperfunction of the hypothalamic-pituitary-adrenal axis, which may contribute to the complex symptoms associated with PCOS.

In a study of 30 women with polycystic ovary syndrome (PCOS), 70% had elevated levels of DHEA sulfate and 53% had elevated 11 beta-hydroxyandrostenedione, indicating significant adrenal androgen excess in this population.

After 3 to 6 months of GnRH agonist therapy, the number of women with elevated DHEA sulfate decreased to 37%, suggesting that the therapy can effectively reduce adrenal androgen levels, particularly in those with initially high levels.

The novel recombinant human chorionic gonadotropin (rhCG; CG beta) was found to be safe and well-tolerated in a first-in-human trial involving 84 healthy subjects, indicating its potential for further clinical development.

CG beta demonstrated higher pharmacokinetic (PK) exposure compared to CG alfa, with a longer half-life and greater serum testosterone response, suggesting that it may be effective at lower therapeutic doses.

In a study comparing 13 women with polycystic ovary syndrome (PCOS) to 15 healthy women, both groups showed similar increases in androgen levels during an ACTH infusion, indicating that the adrenal response to ACTH is not impaired in women with PCOS.

The findings suggest that the hyperandrogenemia seen in PCOS may result from dysregulated steroid production in both the adrenal glands and ovaries, as individual responses to ACTH and hCG were significantly correlated in women with PCOS.

In a study of 45 women with polycystic ovary syndrome (PCOS) compared to 27 controls, significant increases in serum androstenedione, total and free testosterone were observed, confirming a hyperandrogenic state in PCOS patients.

The study also revealed overactivity of the hypothalamic-pituitary-adrenal axis in PCOS, indicated by increased urinary free cortisol and decreased corticosteroid-binding globulin, suggesting that urinary free cortisol is not a reliable marker to differentiate PCOS from Cushing's disease.

In a study of 1741 women with polycystic ovary syndrome (PCOS), obesity was linked to higher levels of testosterone, which increased the risk of symptoms like hirsutism, infertility, and menstrual cycle disturbances.

The research found that elevated luteinizing hormone (LH) levels above 10 IU/l were associated with infertility, suggesting that weight loss could improve symptoms and that treatment should be tailored based on hormone levels.

In a study of 204 women with PCOS, using gold standard methods for measuring free testosterone (FT) revealed that 70.6% were hyperandrogenemic, while routine assays significantly misclassified 29.4% of patients, affecting their clinical phenotype assignment.

The findings suggest that relying on routine testosterone assays can lead to incorrect classifications of PCOS phenotypes and metabolic risk, highlighting the importance of using accurate measurement techniques for better diagnosis and treatment.

In a study comparing 24 unexplained infertile women to 13 fertile women, the infertile group showed significantly higher baseline testosterone levels, indicating that their elevated testosterone likely originated from ovarian sources.

Despite the higher testosterone levels, 46.66% of the infertile women who received follow-up treatment successfully conceived after ovulation induction therapy, suggesting that elevated testosterone may not preclude successful fertility treatments.

Both 'classic' polycystic ovary syndrome (PCO) patients and 'PCO-like' patients show elevated adrenal androgen responses, specifically androstenedione and dehydroepiandrosterone (DHEA), when stimulated with corticotropin-releasing factor (CRF).

Basal levels of DHEA sulfate (DHEA-S) do not effectively predict adrenal responses to CRF, indicating that DHEA-S may not be a reliable marker for adrenal hyperactivity in these patients.

In a study of 187 non-obese women aged 18-35, higher serum Anti-Müllerian hormone (AMH) levels were significantly associated with menstrual disturbances, indicating that AMH could be a useful biomarker for diagnosing PCOS-related menstrual issues.

Women with serum AMH levels greater than 60 pmol/L had a 28.5-fold increased likelihood of experiencing menstrual disturbances compared to those with lower AMH levels, highlighting the potential of AMH in identifying women at risk for PCOS.

In women with polycystic ovary syndrome (PCOS), a low dose ACTH stimulation test (1 microg) revealed adrenal hyperactivity, particularly shown by increased levels of dehydroepiandrosterone sulfate (DHEAS).

The study found that at a standard dose of ACTH (250 microg), women with PCOS had significantly higher responses of 17-hydroxyprogesterone, androstenedione, and DHEAS compared to healthy women, indicating dysregulation of adrenal hormone production in PCOS.
