Outcome Measures

Primary Outcomes (1)

  • Change From Baseline to Endpoint at Week 8 Using the Total Score of the Hamilton Depression Rating Scale (HAM-D)

    Hamilton Rating Scale for Depression (HAM-D) assesses the range of symptoms that are most frequently observed in subjects with major depressive disorder (MDD) on a scale from 0 to 52. Higher HAM-D scores indicate more severe levels of depressive symptoms, thus, a negative change from baseline indicates a reduction (or improvement) in depressive symptoms.
