Cyclical Neuroactive Steroid Changes, Arousal, and Proximal Suicide Risk: An Experimental Approach

University of Illinois at Chicago·interventional·Posted Oct 2, 2019·Updated Dec 19, 2025

In Brief

A Phase 4 clinical trial evaluating Estradiol Transdermal Patch 0.1 mg/24 hrs, Oral Micronized Progesterone 200mg, and 2 other interventions for Suicidal Ideation. Completed, enrolled 124 participants across 1 site.

Detailed Summary

Female suicide attempts occur more often in the weeks before and after menses onset, and have been linked to ovarian hormone withdrawal. The proposed project will use a two-week intervention to stabilize hormones in females with recent suicidal thoughts; this paradigm is a safe way to learn how cyclical changes in hormones and their metabolites influence short-term risk of suicide. The data acquired will contribute to our understanding of the biology of acute suicide risk and advance efforts to develop safe and effective treatments that eliminate predictable monthly worsening of suicide risk in reproductive-age females.
