Effects of pregnenolone on depression in menopausal women

Targeting Allopregnanolone to Probe Behavioral and Neurobiological Mechanisms That Underlie Depression in Women Across the Menopause Transition

Not applicable Interventional Brigham and Women's Hospital · NCT06238700

What this trial studies

This study investigates how increasing allopregnanolone levels through the dietary supplement pregnenolone may influence behavior and neurobiology related to depression in midlife women undergoing menopause. It focuses on the hypothesis that declining natural allopregnanolone levels contribute to perimenopausal depression. The trial is designed as a randomized, double-blind, placebo-controlled study, comparing the effects of pregnenolone against a placebo on depressive symptoms. Key measurements will assess the relationship between hormonal changes and depression during the menopause transition.

Who should consider this trial

Good fit: Ideal candidates are healthy women aged 40 to 60 years experiencing depressive symptoms during the menopause transition.

Not a fit: Patients currently on systemic hormone therapy or with primary psychiatric illnesses may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel treatment approach for alleviating depression in perimenopausal women.

How similar studies have performed: While the approach of manipulating allopregnanolone levels is innovative, similar studies have shown promise in understanding hormonal influences on mood disorders.
