Prazo
Number of Participants With Treatment-Emergent Adverse Events (AEs)
Prazo: First dose up to last dose (up-to Week 12) plus 30 days
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious AE (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to 30 days after last dose that were absent before treatment or that worsened relative to pretreatment state. AEs included both non-serious AEs and SAEs.
First dose up to last dose (up-to Week 12) plus 30 days
Number of Participants With Treatment Emergent Treatment-Related Adverse Events (AEs)
Prazo: First dose up to last dose (up-to Week 12) plus 30 days
Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent were events between first dose of study drug and up to 30 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Relatedness to drug Varenicline was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category. An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. A serious AE (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both non-serious AEs and SAEs.
First dose up to last dose (up-to Week 12) plus 30 days
Number of Participants With Treatment-Emergent Neuropsychiatric Adverse Event Elicited by Neuropsychiatric Adverse Event Interview (NAEI)
Prazo: First dose up to last dose (up-to Week 12) plus 30 days
An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. SAE: AE causing: death; initial/prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent/significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to 30 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Solicited AEs collected by semi-structured NAEI inquiring about AEs: depression, anxiety, delusions, hallucinations, paranoia, psychosis, mania, panic, agitation, dissociative states, feeling abnormal, hostility, aggression and homicidal ideation. If a participant had a positive response to any item on the NAEI, investigator determined if it met criteria AE criteria.
First dose up to last dose (up-to Week 12) plus 30 days
Number of Participants With Categorical Scores on the Columbia Suicide Severity Rating Scale (C-SSRS)
Prazo: Screening, Baseline, Week 1 up to Week 12 (treatment-emergent [TE]), thereafter up to Week 52 (last follow-up [FU])
The C-SSRS (mapped to Columbia Classification Algorithm of Suicide Assessment (C-CASA) categories);was an interview-based instrument to systematically assess suicidal ideation and suicidal behavior.C-SSRS assessed whether participant experienced any of the following:completed suicide;suicide attempt(response of "Yes" on "actual attempt");preparatory acts toward imminent suicidal behavior ("Yes" on "preparatory acts or behavior","aborted attempt" or "interrupted attempt"),suicidal ideation ("Yes" on "wish to be dead","non-specific active suicidal thoughts","active suicidal ideation with methods without intent to act or some intent to act,without specific plan or with specific plan and intent,any self-injurious behavior with no suicidal intent ("Yes" on "Has participant engaged in non-suicidal self-injurious behavior").Here,number of participants with positive response (response of "yes") to suicidal behavior or/and Ideation,any non-suicidal self-injurious behavior were reported.
Screening, Baseline, Week 1 up to Week 12 (treatment-emergent [TE]), thereafter up to Week 52 (last follow-up [FU])
Change From Baseline in Hospital Anxiety and Depression Scale (HADS) - Anxiety (HADS-A) Total Scores at Specified Time-points

The HADS is a self-administered questionnaire measuring anxiety. Hospital Anxiety and Depression Scale Anxiety subscale (HADS-A) consisted of 7 items that were assessed on a scale of 0 = no anxiety to 3 = severe feeling of anxiety. Total HADS-A subscale score range from 0 = no anxiety to 21 = severe anxiety; higher scores indicated more severe anxiety.
Baseline, Weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 20, 28, 36, 44, and 52

Hospital Anxiety and Depression Scale Depression subscale (HADS-D) consists of 7 items that were assessed on a scale of 0 = no depression to 3 = severe feeling of depression. Total HADS-D subscale score range from 0 = no depression to 21 = severe feeling of depression; higher scores indicated a greater intensity of depression.
Baseline, Weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 20, 28, 36, 44, and 52

Baseline up to Week 12
Change From Baseline in Blood Pressure (BP) at Week 12
Prazo: Baseline, Week 12
Measurement of BP included supine and sitting systolic BP, standing systolic BP, supine and sitting diastolic BP and standing diastolic BP. Blood pressure was taken after participants rested in a sitting position for 5 minutes. BP was recorded after participants had been supine for approximately 5 minutes, and then orthostatic blood pressure was recorded immediately when the participant stood.
