Trial Outcomes & Findings for Clinical Evaluation of BRL29060A (Paroxetine Hydrochloride Hydrate) in Posttraumatic Stress Disorder (PTSD) (NCT NCT00557622)

NCT ID: NCT00557622

Last Updated: 2020-11-30

Results Overview

The Clinical-Administered PTSD Scale (CAPS) is a structured interview for assessing PTSD diagnostic status and symptom severity. The CAPS assesses both the frequency and intensity of individual PTSD symptoms on separate five-point (0-4) rating scales, and these ratings can be summed to create a nine-point (0-8) severity score for each symptom. The total CAPS score can range from 0 to 136, with a higher value indicating increased severity. A minus value for change from baseline indicates an improvement of symptom severity.

Participant Flow

Prior to assignment to the 12-week treatment phase, all participants received placebo in a single-blind manner in a 4-week run-in phase. Participants completing the run-in phase were then randomized to receive either placebo or paroxetine for the remainder of the study. Two participants were withdrawn from the study before randomization.

PRIMARY outcome

Timeframe: Baseline and Week 12

Population: Full Analysis Set (FAS): All participants who received at least one dose of study medication for the treatment phase and had at least one post-baseline efficacy assessment. Participants who failed to satisfy major entry criteria measured prior to randomization (e.g., participant with disease other than PTSD) were excluded.

Timeframe: Baseline and Week 12

Participants who failed to satisfy major entry criteria measured prior to randomization (e.g., participant with disease other than PTSD) were excluded.

Change in regional blood flow (rCBF) measured by fMRI represents altered neuronal responses in PTSD patients and is considered to be the biomarker for treatment response. fMRI measures are provided as blood oxygeneration level-dependent (BOLD) signals (z-score). To trigger neuronal activation, 2 visual stimuli were used: MVA-task (consisting of MVA-related and unpleasant pictures) and face-task (consisting of a variety of facial expressions \[e.g., neutral, happy, fear\]). Week 0 and 12 rCBF data from 1 participant were invalid (involuntary movement in the fMRI machine); no analysis was done.
