Secondary Outcome Measures:
  • Number of Participants Reporting Treatment Emergent Adverse Events (TEAE). [ Time Frame: Starting at the time the ICF was signed to Day 126/Early termination ] [ Designated as safety issue: Yes ]
    Safety was measured according to standard adverse event collection as described in the adverse event section of the results.

  • Number of Participants With Laboratory Values of Potential Clinical Relevance. [ Time Frame: Day 1, Day 28, Day 126/Early termination ] [ Designated as safety issue: Yes ]
    The laboratory tests were collected and processed in accordance with directions from the clinical chemistry laboratory. Based on criteria for identifying laboratory values of potential clinical relevance, the abnormal values were noted. Some of the criteria are as follows: For fasting triglycerides: men: ≥ 160 mg/dL and women: ≥ 120 mg/dL; Fasting glucose: ≥ 115 mg/dL; Prolactin: > upper limit of normal (ULN); Neutrophils: ≤ 1,500/mm3; and Creatine phosphokinase: ≥ 3 x ULN.

  • Number of Participants With Vital Signs of Potential Clinical Relevance-Blood Pressure [ Time Frame: Day 1, Day 14, Day 28 and Day 126/Early termination ] [ Designated as safety issue: Yes ]
    Vital sign assessment included orthostatic (supine and standing) blood pressure. Orthostatic assessments were made after participants had been in the supine position for at least 5 minutes and again after participants had been standing for 2 minutes, but not more than 3 minutes. Orthostatic hypotension defined as >/= 20 mm Hg decrease in systolic blood pressure and >/= 25 beats per minute increase in heart rate from supine to standing.

  • Number of Participants With Vital Signs of Potential Clinical Relevance-Temperature [ Time Frame: Day 1, Day 14, Day 28 and Day 126/Early termination ] [ Designated as safety issue: Yes ]
    Vital sign assessment included body temperature measured in centigrade(C). Temperatures >=37.8°C and increase of >= 1.1°C were recorded.

  • Number of Participants With Vital Signs of Potential Clinical Relevance-Heart Rate [ Time Frame: Day 1, Day 14, Day 28 and Day 126/Early termination ] [ Designated as safety issue: Yes ]
    Vital sign assessment included heart rate (supine and standing). Heart rate with increase or decrease of >/= 15 beats per minute were recorded.

  • Number of Participants With Electrocardiogram (ECG) Measurements of Potential Clinical Relevance [ Time Frame: Day 1, Day 14, Day 28 and Day 126/Early termination ] [ Designated as safety issue: Yes ]
    Three 12 lead ECGs were performed approximately 5 minutes apart at each time point. The participant were supine and at rest (for at least 10 minutes) prior to the first ECG and will remain supine through the final ECG. Based on criteria for identifying ECG measurements of potential clinical relevance, the abnormal values were noted. Some of the criteria are as follows: For bradycardia: ≤ 50 beats per minute (bpm); and for increase in QTc: QTc ≥ 450msec.

  • Visual Analog Scale (VAS) Score at Day 1, Day 14, Day 28 and Last Visit. [ Time Frame: Day 1, Day 14, Day 28 and last visit ] [ Designated as safety issue: Yes ]
    Injection site pain was assessed using a VAS, which was completed by the trial participant, and the investigator's assessment of most recent injection site, which was completed by the investigator. VAS is 100 mm line, 0=no pain, 100=unbearably painful.

  • Number of Participants With Categorical Scores on the Columbia Suicide Severity Rating Scale. [ Time Frame: Screening, Baseline, Week 1, Week 2, Week 8, Week 18 visit and Last visit. ] [ Designated as safety issue: Yes ]
    This scale consists of a baseline evaluation that assesses the lifetime experience of the participant with suicide events and suicidal ideation and a post baseline evaluation that focuses on suicidality since the last trial visit.
