NCT01000493

Brief Summary

This is a 12-week, randomized, multicenter, double-blind, placebo controlled, fixed-dose parallel group study to assess the efficacy and safety of orvepitant (60 mg/day) versus placebo in subjects with a diagnosis of noncombat-related Posttraumatic Stress Disorder (PTSD), whose symptoms are considered moderate or severe. Following an initial screening visit, subjects fulfilling the study inclusion and exclusion criteria will enter a pre-treatment screening phase to permit evaluation of the laboratory and ECG assessments and to confirm eligibility for inclusion into the study. This screening phase will be a minimum of 7 days, but no longer than 21 days. At the completion of the screening period, eligible subjects will be randomized at the baseline visit to receive either orvepitant 60mg/day or placebo (1:1 ratio). Those subjects randomized to receive placebo will receive study medication identical in appearance to that received by subjects assigned to receive orvepitant. Efficacy will be assessed using the Clinician Administered PTSD Scale (CAPS) as the primary efficacy measure. Key secondary efficacy endpoints will be based on the Davidson Trauma Scale (DTS), the Short PTSD Rating Interview (SPRINT), the Clinical Global Impression- Global Improvement and Severity of Illness Scales (CGI-I and CGI-S, respectively), the Hamilton Depression Rating Scale (HAM-D), the Cognitive and Physical Functioning Questionnaire (CPFQ) and the Pittsburgh Sleep Quality Index (PSQI). Safety will be assessed by monitoring for adverse events (side effects) and through periodic laboratory evaluations (blood tests), vital signs assessments (e.g., blood pressure, heart rate, temperature) and heart function measurements (electrocardiograms, or ECGs).

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in the 17-item Clinician Administered Posttraumatic Stress Disorder (PTSD) Scale (CAPS) Total Severity Score at Week 12

    The CAPS was a 30-item clinical interview. Both frequency (0: never; 4: daily or all the time) and intensity (0: none or no problem with symptoms; 4: extreme, incapacitating) ratings were made on a 5-point scale. The CAPS total severity score was based on the 17 items that assess the frequency and intensity of PTSD symptoms. There were 8 items assessing associated features (guilt, hopelessness, memory impairment, overall response validity, global PTSD severity, global improvement and social and occupational impairment). The total score 0-136, higher scores means more severity, \< 20: few symptoms or being asymptomatic, 20-39: mild or subthreshold PTSD, 40-59: threshold and moderate PTSD, 60-79: severe PTSD symptoms and \> 80: extreme PTSD symptoms. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. Baseline was defined as value on Day 1 (pre-dose).

    Baseline (Day 1 pre-dose) and Week 12

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:
