Outcome Measures

Primary Outcomes (1)

  • Change from baseline in the Hamilton Depression Rating Scale, 17-item (HAMD-17) score at Week 6

    The HAMD-17 consists of 17 items that are used to rate the severity of depression symptoms. Each item is scored in a range of 0 to 2 points or 0 to 4 points, with higher scores indicating a greater degree of depression. The score for each item is summed to compute a total score, which ranges from 0 to 52 points.

    Baseline to Week 6

Secondary Outcomes (4)

  • Change from baseline in the Snaith-Hamilton Pleasure Scale (SHAPS) score at Week 6

    Baseline to Week 6

  • Change from baseline in the Hamilton Depression Rating Scale, 17-item (HAMD-17) score at Week 1

    Baseline to Week 1

  • Change from baseline in the Clinical Global Impression of Severity (CGI-S) score at Week 6

    Baseline to Week 6

  • To assess the safety and tolerability of azetukalner (e.g., adverse events)

    From screening (approximately 4 weeks prior to baseline) through to 8 weeks post-final dose.
