What researchers measure

Primary outcomes

  1. RE104 30 mg versus RE104 1.5 mg change from baseline in MADRS total score

    Montgomery-Åsberg Depression Rating Scale (MADRS) is a 10-item clinician rated scale measuring depression severity. The total score ranges from 0-60 with higher scores representing greater severity of depression.

    Time frame: Day 7

Secondary outcomes

  1. RE104 30 mg versus RE104 1.5 mg changes in total score from baseline in Hamilton Anxiety Rating Scale (HAM-A)

    The Hamilton Rating Scale for Anxiety (HAM-A) is a 14-item scale that is used to rate the severity of symptoms of anxiety. The total score ranges from 0-56 with higher scores representing greater severity of anxiety.

    Time frame: Day 7

  2. RE104 30 mg versus RE104 1.5 mg incidence of treatment-emergent adverse events (TEAEs) by frequency, severity and seriousness.

    A treatment-emergent adverse event (TEAE) is defined as any unfavorable and unintended sign, symptom or disease temporally associated with the use of a study drug.

    Time frame: From dosing through study completion (post-dose follow-up is for 42 days)
