Exclusion criteria

Primary

MeasureTime frameDescription
RE104 30 mg versus RE104 1.5 mg change from baseline in MADRS total scoreDay 7Montgomery-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.

Secondary

MeasureTime frameDescription
RE104 30 mg versus RE104 1.5 mg percentage of patients with MADRS remission (score ≤ to 10)Day 7Montgomery-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.
RE104 30 mg versus RE104 1.5 mg Clinical Global Impression-Improvement (CGI-I)Day 1, Day 7 and Day 28The Clinical Global Impression - Improvement (CGI-I) Scale is a clinician-rated instrument that weighs the clinical impact of the identified symptom(s) on behavior and function and measures changes in psychopathology since the treatment was administered on a scale from 1 (very much improved) to 7 (very much worse).
RE104 30 mg versus RE104 1.5 mg change from baseline in CGI-Severity (CGI-S)Day 1, Day 7 and Day 28The Clinical Global Impression - Severity Scale is a clinician-rated instrument that grades severity of symptoms on a scale from 1 (normal, not ill at all) to 7 (among the most extremely ill patients).
RE104 30 mg versus RE104 1.5 mg changes in total score from baseline in Hamilton Anxiety Rating Scale (HAM-A)Day 7The 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.
RE104 30 mg versus RE104 1.5 mg incidence of treatment-emergent adverse events (TEAEs) by frequency, severity and seriousness.From dosing through study completion (post-dose follow-up is for 28 days)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.
RE104 30 mg versus RE104 1.5 mg percentage of patients with MADRS response (≥ 50 percent reduction in score from baseline)Day 7Montgomery-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.
