Experimental: NYX-783 Low Dose Drug: NYX-783
NYX-783 is a small molecule that modulates the N-methyl-D-aspartate receptor (NMDAR).

Experimental: NYX-783 High Dose Drug: NYX-783
NYX-783 is a small molecule that modulates the N-methyl-D-aspartate receptor (NMDAR).




Primary Outcome Measures :
  1. CAPS-5 (Clinician-Administered PTSD Scale for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition)) Total Score and Subscores [ Time Frame: From baseline to week 4 and Week 4 to Week 8 ]
    Change in CAPS-5 total score and Subscores


Secondary Outcome Measures :
  1. PCL-5 (PTSD-Checklist for DSM-5) [ Time Frame: From baseline to week 4 and Week 4 to Week 8 ]
    Assess the effect of NYX-783 compared to placebo in changes of symptoms as measured by PCL-5

  2. PSQI (Pittsburgh Sleep Quality Index) Global Score [ Time Frame: From baseline to week 4 and Week 4 to Week 8 ]
    Assess the effects of NYX-783 compared to placebo in changes in sleep quality as measure by the PSQI Global Score

  3. PSQI-A (Pittsburgh Sleep Quality Index-Addendum) Global Score [ Time Frame: From baseline to week 4 and Week 4 to Week 8 ]
    Assess the effects of NYX-783 compared to placebo in changes in sleep quality as measure by the PSQI-A Global Score

  4. BAC Symbol Coding (Brief Assessment of Cognition) [ Time Frame: From baseline to week 4 and Week 4 to Week 8 ]
    Assess the effect of NYX-783 compared to placebo in changes in cognitive function as measured by the BAC Symbol Coding

  5. CGI-S (Clinical Global Impression - Severity) [ Time Frame: From baseline to week 4 and Week 4 to Week 8 ]
    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

  6. HADS (Hospital Anxiety and Depression Scale) [ Time Frame: From baseline to week 4 and Week 4 to Week 8 ]
    Compare NYX-783 vs. placebo in the changes in levels of anxiety and depression as measured by the HADS
