ListOutcomeTime frameDescription
PrimaryChange From Baseline in Hamilton Depression Rating Scale (HAMD-17) Total Score at Weeks 8Baseline and at Week 8
The HAMD-17 was a 17-item clinician-rated instrument used to assess the range of symptoms that were most frequently observed in participants with major depression. All items were scored on an ordinal scale between 0 and 4 (9 items) or 0 and 2 (8 items) of increasing severity. Each of 17 items was rated by clinician with rating of 0: absent, 1: doubtful to mild, 2: mild to moderate, 3: moderate to severe, and 4: very severe. A total score (0 to 52) was calculated by adding scores of all 17 items, where 0 indicated no depression and 52 indicated severe depression. Higher score represents more severe condition. Baseline is defined as the latest non-missing measurement prior to or within 1 hour of the first administration of study drug. Change from Baseline is defined as post dose visit value minus Baseline value.
SecondaryClinical Global Impression of Improvement (CGI-I) ScoreAt Week 8
The CGI-I scale is a clinician-rated instrument that measures the improvement of the participant's symptoms. It is a 7-point scale where a score of 1 indicates that the participants is "very much improved," a score of 4 indicates that the participant has experienced "no change, and a score of 7 indicates that the participant is "very much worse." The total score is the item response; lower scores indicate greater improvement.
SecondaryChange From Baseline in Snaith-Hamilton Pleasure Scale (SHAPS) ScoreBaseline and at Week 8
The SHAPS is a self-report 14-item, instrument, developed for the assessment of hedonic capacity. Participants score whether they experience pleasure in performing a list of activities or experiences. Participants can rate the answers as "definitely/strongly agree", "agree", "disagree" or "strongly disagree". "Definitely agree" will be rated 1, "Agree" will be rated 2, "Disagree" will be rated 3, and "Definitely disagree" will be rated 4. The participant's item responses are summed to provide a total score ranging from 14 to 56. A higher total SHAPS score indicates higher levels of current anhedonia. Baseline is defined as the latest non-missing measurement prior to or within 1 hour of the first administration of study drug. Change from Baseline is defined as post dose visit value minus Baseline value.
SecondaryChange From Baseline in Hospital Anxiety and Depression Scale (HADS) Subscales (ie, Anxiety Subscale [HADS-A] and Depression Subscale [HADS-D]) ScoresBaseline and at Week 8
The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-report questionnaire with 2 subscales: anxiety and depression. Seven of the items are used to evaluate anxiety and 7 evaluate depression. Each item on the questionnaire is scored from 0 to 3. Therefore, the anxiety subscale (HADS-A) and the depression subscale (HADS-D) each range from 0 to 21. Higher scores indicate higher levels of anxiety and depression, respectively. Baseline is defined as the latest non-missing measurement prior to or within 1 hour of the first administration of study drug. Change from Baseline is defined as post dose visit value minus Baseline value.
SecondaryChange From Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total ScoreBaseline and at Week 8
The HAM-A was administered to assess severity of anxiety, its improvement during the course of treatment, and the timing of such improvement. This instrument was completed by qualified and trained investigator site raters based on a semi-structured interview of his/her assessment of the participant. The HAM-A is a 14-item scale to measure severity of different anxiety-related symptoms in participants. Each of the 14 items is rated by the clinician on a 5-point scale ranging from 0 (not present) to 4 (maximum degree) with a total score range of 0 to 56 where higher score indicates greater symptom severity. Baseline is defined as the latest non-missing measurement prior to or within 1 hour of the first administration of study drug. Change from Baseline is defined as post dose visit value minus Baseline value.
SecondaryChange From Baseline in Sheehan Disability Scale (SDS) ScoresBaseline and at Week 8
The Sheehan Disability Scale (SDS) is a 3-item self-rated questionnaire used to evaluate impairments in the domains of work/school, social life, and family life/home responsibility on a 10-point visual analog scale. In each domain of the overall scale, the minimum score is a 0 (indicating that symptoms have been 'not at all' disruptive to functioning) and the maximum score is a 10 (indicating that symptoms have been 'extremely' disruptive to functioning). The three items were summed into a single dimensional measure of global functional impairment with total score ranging from 0 (unimpaired) to 30 (highly impaired) with the highest scores representing the higher level of disability/greater functional impairment. SDS Total Score is calculated for subjects with all 3 domain scores (work/school, social, and family life) and an unmarked checkbox for "No work or school". Baseline is defined as Day 1. Change from Baseline is defined as the post dose visit value minus the Baseline value.
SecondaryChange From Baseline to Week 8 in Clinical Global Impression Scale - Severity (CGI-S) ScoresBaseline and at Week 8
The CGI-S is a clinician-rated instrument that measures the severity of depression at the time of assessment. This rating is based upon observed and reported symptoms, behavior, and function in the past 7 days. The score reflected the average severity level across the 7 days. The CGI-S is scored on a 7-point scale where a score of 1 indicates that the participant is normal, not at all ill, a score of 4 indicates that the participant is moderately ill, and a score of 7 indicates that the participant is among the most extremely ill participants. Baseline is defined as the latest non-missing measurement prior to or within 1 hour of the first administration of study drug.
SecondaryPercentage of Participants With a HAMD-17 ResponseAt Week 8
The HAMD-17 is a 17-item clinician-rated instrument used to assess the range of symptoms that were most frequently observed in participants with major depression. All items were scored on an ordinal scale between 0 and 4 (9 items) or 0 and 2 (8 items) of increasing severity. Each of 17 items was rated by clinician with rating of 0: absent, 1: doubtful to mild, 2: mild to moderate, 3: moderate to severe, and 4: very severe. A total score (0 to 52) was calculated by adding scores of all 17 items, where 0 indicated no depression and 52 indicated severe depression. Higher score represented more severe condition. HAMD-17 response rate, where response is defined as ≥ 50% decrease in HAMD-17 total score from Baseline to Week 8.
SecondaryNumber of Participants Reporting >2% Treatment Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), and Adverse Events of Special Interest (AESIs)Up to 8 Weeks
An AE is any event that was not present prior to the initiation of study treatment, or any event already present that worsens in either intensity or frequency following exposure to study treatment. A TEAE is any event that was not present prior to the initiation of study treatment, or any event already present that worsens in either intensity or frequency following exposure to study treatment. An SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect or is an important medical event that may jeopardize the participant or may require medical or surgical intervention to prevent one of the above outcomes.
SecondaryNumber of Participants With Clinically Significant Changes in Hematology ParametersUp to 8 Weeks
Blood samples were collected for the analysis of hematology parameters - basophils, eosinophils, erythrocyte mean corpuscular hemoglobin, erythrocyte mean corpuscular volume, erythrocytes, hematocrit, hemoglobin, leukocytes, lymphocytes, monocytes, neutrophils and reticulocytes
