Number of Participants With Treatment-Emergent Adverse Events (AEs)First dose up to last dose (up-to Week 12) plus 30 daysAn 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.
Change From Baseline in Pulse Rate at Week 12Baseline, Week 12Measurement of pulse rate included supine, sitting and standing pulse rate. Pulse rate was taken after participants rested in a sitting position for 5 minutes. Pulse rate was recorded after participants had been supine for approximately 5 minutes and then immediately upon standing.
Change From Baseline in Blood Pressure (BP) at Week 12Baseline, Week 12Measurement of BP included supine and sitting systolic BP, standing systolic BP, supine and sitting diastolic BP and standing diastolic BP.

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.

Time frame: Baseline, Weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 20, 28, 36, 44, and 52

Population: The safety analysis set included all participants who took at least one dose of randomized study medication, including partial doses. Here, 'Number analyzed' signifies participants evaluable for this outcome measure at specified timepoints.

Number of Participants With Categorical Scores on the Columbia Suicide Severity Rating Scale (C-SSRS)

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.

Time frame: Screening, Baseline, Week 1 up to Week 12 (treatment-emergent [TE]), thereafter up to Week 52 (last follow-up [FU])

Population: The safety analysis set included all participants who took at least one dose of randomized study medication, including partial doses.

Number of Participants With Treatment-Emergent Adverse Events (AEs)

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.

Time frame: First dose up to last dose (up-to Week 12) plus 30 days

Population: The safety analysis set included all participants who took at least one dose of randomized study medication, including partial doses.

Number of Participants With Treatment-Emergent Neuropsychiatric Adverse Event Elicited by Neuropsychiatric Adverse Event Interview (NAEI)

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.

Number of Participants With Treatment Emergent Treatment-Related Adverse Events (AEs)

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.
