NCT03973229

Brief Summary

This study will test for effects of estradiol (E2) on PTSD symptoms and functional magnetic resonance imaging (fMRI) indicators of stress vulnerability, in naturally-cycling women who are not using hormonal birth control. Enrollment will be targeted to create three groups within two cohorts (early follicular phase and luteal phase):

  1. 1.PTSD: Women who meet Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for PTSD
  2. 2.Trauma-Exposed (TC): Women matched for age and trauma exposure severity but without PTSD
  3. 3.Healthy Control (HC): Women matched for age, but without trauma history or psychiatric disorder (self-reported)

Outcome Measures

Primary Outcomes (3)

  • Change in amygdala response to fearful faces stimuli

    Responses to threat cues will be assessed by fMRI responses as participants view 15 blocks each of fearful face and neutral face stimuli, while amygdala reactivity is measured.

    Mid-cycle second cycle, Mid-cycle third cycle (each cycle is an average of 28 days)

  • Change in amygdala response to fear conditioning task

    Indicators of fear conditioning will be assessed by fMRI during the fear conditioning tasks. Deficits in fear inhibition have been present in persons with PTSD and during phases of the ovarian cycle.

    Mid-cycle second cycle, Mid-cycle third cycle (each cycle is an average of 28 days)

  • Change in ventromedial prefrontal cortex (vmPFC) activation during the fear extinction task

    Indicators of fear extinction will be assessed by fMRI during the fear extinction tasks. Fear extinction is impaired in persons with PTSD and depends on the vmPFC and its inhibition of amygdala responses to threat stimuli.

    Mid-cycle second cycle, Mid-cycle third cycle (each cycle is an average of 28 days)

Secondary Outcomes (2)

  • Change in PTSD checklist for DSM-5 (PCL-5)

    Baseline, Mid-cycle second cycle, Mid-cycle third cycle (each cycle is an average of 28 days)

  • Change in Beck Depression Inventory (BDI)

    Baseline, Mid-cycle second cycle, Mid-cycle third cycle (each cycle is an average of 28 days)

Masking Details
Randomization will be double blind, with the key held by the study coordinator in a locked file. The study coordinator will do checks of appropriate enrollment to groups after each 20 participants, but no blind will be broken to individuals analyzing study data. Grady pharmacy services will also hold the randomization schedule, as they will dispense the appropriate patch at the appropriate time point.

Shared Documents
STUDY PROTOCOL
Time Frame
