Study on Allopregnanolone and Depression in Perimenopausal Women

Phase 4TerminatedNCT05329779

Brigham and Women's Hospital2 enrolled

Overview

This study aims to identify how the progesterone metabolite allopregnanolone affects behavior and neurobiology that may underlie perimenopausal depression.

Midlife women are burdened with depression risk that is at least partly attributed to changing reproductive steroid dynamics across a prolonged reproductive transition. The investigators hypothesize that declining endogenous allopregnanolone (ALLO) levels across the menopause transition underlies perimenopausal depression. This mechanistic trial aims to amplify the contrast between lower endogenous ALLO levels in perimenopausal women and higher levels experimentally induced by exogenous ALLO. This will be achieved by using the exogenous ALLO treatment, brexanolone, which is FDA-approved to treat depression in postpartum patients, in a randomized, double-blind, parallel-arm, placebo-controlled trial. By manipulating ALLO levels together with key measurement of depression domains, this study harnesses the endocrine biology of perimenopause to explicate behavioral and neurobiological mechanisms underlying depression in perimenopausal women.

Outcomes

Primary Outcomes

Within-person Change in Score on the Ruminative Responses Scale

The Ruminative Responses Scale (RRS) comprises 22 items which ask how frequently the participant thinks certain statements when they feel depressed. Each item is scored from 1-4. Total scores range from 22-88 with higher scores indicating more severe rumination.

Time frame: Baseline to 4 days
