Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • A primary diagnosis of PTSD [Post Traumatic Stress Disorder, according to DSM-5 (Diagnostic and Statistical Manual of Mental Disorders)] with the primary traumatic event occurring ≥12 months prior to screening.

Primary Outcome Measures

CAPS-5 [Clinician-Administered PTSD Scale for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition)] Total Score and Subscores
CAPS-5 [Clinician Administered PTSD Scale for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition)] is a structured interview for diagnosis and assessment of PTSD. The assessor combines information about frequency and intensity of an item into a severity rating (0-4). CAPS-5 total symptom severity score is calculated by summing severity scores for the 20 DSM-5 PTSD symptoms. CAPS-5 symptom cluster severity scores are calculated by summing the individual item severity scores for symptoms corresponding to a given DSM-5 cluster: intrusions (items 1-5, minimum score 0, maximum score 20), avoidance (items 6-7, minimum score 0, maximum score 8), negative alterations in cognitions and mood (items 8-14, minimum score 0, maximum score 28), and alterations in arousal and reactivity (items 15-20, minimum score 0, maximum score 24). CAPS-5 Total Scores range from 0 to 80. A higher score corresponds to more severe PTSD.

Secondary Outcome Measures

PCL-5 (PTSD-Checklist for DSM-5)
Assess the effect of NYX-783 compared to placebo in changes of symptoms as measured by PCL-5. The PCL-5 ranges from 0 to 80; a higher score corresponds to more severe PTSD.
PSQI (Pittsburgh Sleep Quality Index) Global Score
Assess the effects of NYX-783 compared to placebo in changes in sleep quality as measure by the PSQI Global Score. The PSQI is a questionnaire to assess sleep quality and disturbances. In scoring the PSQI, seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality. A score >5 indicates significant sleep disturbance.
PSQI-A (Pittsburgh Sleep Quality Index-Addendum) Global Score
Assess the effects of NYX-783 compared to placebo in changes in sleep quality as measure by the PSQI-A Global Score. The PSQI-A score ranges from 0-21; lower scores represent less disruptive behavior.
BAC (Brief Assessment of Cognition) Symbol Coding
Assess the effect of NYX-783 compared to placebo in changes in cognitive function as measured by the BAC Symbol Coding. BAC symbol coding score is a count which ranges from 0 to 110; higher scores represent higher function.
CGI-S (Clinical Global Impression - Severity)
Assess the effect of NYX-783 compared to placebo in the change in global clinical severity of PTSD symptoms as measured by the CGI-S. The Clinical Global Impressions-Severity (CGI-S) score ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill subjects).
HADS-A (Hospital Anxiety and Depression Scale)
The HADS is a self-assessment tool consisting of two subscales, one for anxiety (HADS-A) and one for depression (HADS-D). Scores for items in each subscale of the HADS are summed to produce an anxiety score (HADS-A) or a Depression score (HADS-D), or can be added to produce a total score (HADS-T). Each item is rated on a 4-point scale (ranging from 0 = no not at all, to 3 = yes definitely), for a total score ranging from 0-42 and sub scores for anxiety or depression ranging from 0-21 for each subscale. Higher scores represent more severe anxiety or depression. HADS-A is presented here.
