Trial Outcomes & Findings for Neurosteroids for Treatment of PTSD in Veterans (NCT NCT03799562)

NCT ID: NCT03799562

Last Updated: 2026-08-26

Results Overview

The CAPS is the gold standard in PTSD assessment. The CAPS-5 is a 30-item structured interview that can be used to make a diagnosis of PTSD and assess PTSD symptoms. It assesses the intensity and frequency of PTSD symptoms. Scores range from 0-80; higher score indicates greater severity.

Participant Flow

Eligible participants were identified by searching the VA clinical data warehouse for patients with PTSD and residing within a reasonable travel distance from the Durham VA Medical Center, Durham, NC. Potential candidates were enrolled at in-person screening visits between June 2019 and May 2025. Recruitment was on hold from March 2020 - May 2021 due to COVID epidemic restrictions.

Of 236 screened participants, 97 met inclusion criteria and were randomized to treatment. Of the 97 randomized participants, two were later found to be ineligible due to laboratory findings and did not receive actual treatment. Thus in total, 95 participants received study drug. The primary analysis for this phase II study was conducted within treated participants (modified intent-to-treat).

PRIMARY outcome

Timeframe: Study drug onset to treatment week 8

Population: This summary represents the 74 participants retained to treatment week 8. Of those, 7 participants had incomplete CAPS-5 measures such that the endpoint determination is missing.

SECONDARY outcome

Timeframe: Study drug onset to treatment week 8

Population: This summary represents the 74 participants retained to treatment week 8. Of those, 4 participants had incomplete collection of the Brief Pain Inventory measures such that the pain-related endpoint determination is missing.

The Brief Pain Inventory, Short Form (BPI-SF) is a self-reported scale that measures the severity of pain and the interference of pain on function. The scores range from 0 (no pain) to 10 (pain as severe as you can imagine). There are 4 questions assessing worst pain in past 24 hrs, least pain in past 24 hrs, average pain, and pain right now. The Interference scores range from 0 (does not interfere) to 10 (completely interferes). There are 7 questions assessing the interference of pain in the past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life.

SECONDARY outcome

Timeframe: Study drug onset to treatment week 8

Population: This summary represents the 74 participants retained to treatment week 8. Of those, 7 participants had incomplete HAM-D measures such that the endpoint determination is missing.

The HAM-D measures the severity of depressive symptoms. It is a checklist of 17 items that are ranked on a scale of 0-4 or 0-2. The range for the total score (which is the sum of the scores of all 17 items) is 0-52; a higher score indicates greater severity of symptoms.
