Brief summary

The purpose of this research study is to test the study drug, NORA520, as a possible treatment for severe postpartum depression (PPD). The trial aims to determine: * How well NORA520 is tolerated and what side effects it may cause * If NORA520 reduces depressive symptoms in subjects with severe PPD * The amount of NORA520 in the blood at various times after taking the study drug; this provides information that helps determine how often NORA520 should be taken * In a subset of subjects, the amount of NORA520 in breastmilk at various times after taking it to determine if and how much NORA520 can pass into breastmilk Participate in this study will be randomly assigned to one of 3 different groups. All subjects will take the study drug for 3 days.

Design outcomes

Primary

MeasureTime frameDescription
Incidence, severity, and causality of AEs, SAEs, and AESIsUp to Day 30Adverse events (AEs), Serious Adverse Events (SAEs), Adverse Events of Special Interest (AESIs)
Change from baseline in HAM-D17 total score compared to placeboBaseline to Day 4The Seventeen-Item Hamilton Rating Scale for Depression (HAM-D17) contains 17 individual ratings related to the following symptoms: depressed mood, feelings of guilt, suicide, insomnia (initial, middle, and late), work and interests, psychomotor retardation, psychomotor agitation, anxiety (psychic and somatic), gastrointestinal symptoms, general somatic symptoms, sexual interest, hypochondriasis, insight, and weight loss. The total score ranges from 0 to 52, with higher scores indicating more severe depression.

Secondary

MeasureTime frameDescription
Change from baseline in HAM-D17 total scoreBaseline to Days 8 and 30The Seventeen-Item Hamilton Rating Scale for Depression (HAM-D17) contains 17 individual ratings related to the following symptoms: depressed mood, feelings of guilt, suicide, insomnia (initial, middle, and late), work and interests, psychomotor retardation, psychomotor agitation, anxiety (psychic and somatic), gastrointestinal symptoms, general somatic symptoms, sexual interest, hypochondriasis, insight, and weight loss. The total score ranges from 0 to 52, with higher scores indicating more severe depression.
HAM-D17 responseBaseline to Days 4, 8, and 30Defined as having a 50% or greater reduction from baseline in HAM-D17 total score. The total score ranges from 0 to 52, with higher scores indicating more severe depression.
HAM-D17 remissionBaseline to Days 4, 8, and 30Defined as having a HAM-D17 total score ≤7. The total score ranges from 0 to 52, with higher scores indicating more severe depression.
Change from baseline in HAM-D17 subscale and individual item scoresBaseline to Days 4, 8, and 30The Seventeen-Item Hamilton Rating Scale for Depression (HAM-D17) contains 17 individual ratings related to the following symptoms: depressed mood, feelings of guilt, suicide, insomnia (initial, middle, and late), work and interests, psychomotor retardation, psychomotor agitation, anxiety (psychic and somatic), gastrointestinal symptoms, general somatic symptoms, sexual interest, hypochondriasis, insight, and weight loss. The total score ranges from 0 to 52, with higher scores indicating more severe depression.
Change from baseline in Clinical Global Impression - Severity (CGI-S) scoreBaseline to Days 4, 8, and 30The CGI-S scale is a 7-point scale that requires the Investigator to assess how mentally ill is the patient at this time. 1 - normal, not at all ill; 2 - borderline mentally ill; 3 - mildly ill; 4 - moderately ill; 5 - markedly ill; 6 - severely ill; or 7 - among the most extremely ill patients.
Clinical Global Impression - Improvement (CGI-I) scale positive responseBaseline to Days 4, 8, and 30The CGI-I scale is a 7-point scale that requires the Investigator to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of study drug treatment. 1 - very much improved; 2 - much improved; 3 - minimally improved; 4 - no change; 5 - minimally worse; 6 - much worse; or 7 - very much worse
Change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total scoreBaseline to Days 4, 8, and 30The MADRS contains 10 individual items related to the following symptoms: apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. The total score ranges from 0 to 60, with higher scores indicating more severe depression.
Change from baseline in Hamilton Anxiety Rating Scale (HAM-A) total scoreBaseline to Days 4, 8, and 30The HAM-A contains 14 individual ratings related to the following symptoms: anxious mood, tension, fears, insomnia, intellectual, depressed mood, somatic (muscular), somatic (sensory), cardiovascular symptoms, respiratory symptoms, gastrointestinal symptoms, genitourinary symptoms, autonomic symptoms, and behavior at interview. The total score ranges from 0 to 56, with higher scores indicating more severe anxiety.
Change from baseline in Edinburgh Postnatal Depression Scale (EPDS) total scoreBaseline to Days 8 and 30The Edinburgh Postnatal Depression Scale (EPDS) is a set of 10 screening questions. The total score ranges from 0 to 30, with higher scores indicating more severe depression.
Number of patients who start any new antidepressant or anti-anxiety medicationAfter Day 8 assessments through Day 30
