Study Endpoints

Primary Endpoints

Change From Baseline in 17-item Hamilton Raing Scale for Depression (HAM-D17) Total Score at Week 8 or Early Termination
Baseline, Week 8 or Early termination

HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression (symptoms such as depressed mood, work and activities, sleep, suicide, psychomotor agitation/retardation, appetite, sexual interest, anxiety, and somatic symptoms). The items of the HAM-D17 are rated on a scale of 0 to 2 or 0 to 4, and the total score ranges from 0 to 52. Higher scores indicate more severe symptoms. Change from baseline: mean score at Week 8 or early termination minus mean score at baseline.

Evaluation of the efficacy of pregabalin and Venlafaxine XR in the treatment of generalized anxiety disorder.
Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months

Any untoward medical occurrence in a participant who received study drug was considered an adverse event (AE), without regard to possibility of causal relationship. Treatment-emergent adverse events: those which occurred or worsened after baseline. An AE resulting in any of the following outcomes, was considered to be a serious adverse event: death; lifethreatening; initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect.

Number of Participants With Clinical Significant Vital Changes
Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months

Clinical significant changes were pre-defined for systolic blood pressure (SBP), diastolic blood pressure (DBP) , and pulse rate (PR). An average value of 3 measurements in each visit meeting the following criteria for 3 consecutive visits was determined as clinical siginificant changes: DBP \>= 90 mmHg with change from the baseline \>= 10 mmHg; SBP \>= 140 mmHg with change from the baseline \>= 20 mmHg; PR \>= 100 bpm with change from the baseline \>= 15 bpm.

Number of Participants With Clinical Significant Laboratory Tests Changes
Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months

Clinical significant changes were pre-defined for each laboratory test based on the criteria: Red Blood Cell Count \<0.8 x lower limit normal (LLN); Lymphocytes (%) \<0.8 x LLN; Eosinophils (%) \>1.2 x upper limit normal (ULN); Total Bilirubin \>1.5 x ULN; Alanine Aminotransferase (ALT) \>3.0 x ULN; Gamma glutamyl transferase (GGT) \>3.0 x ULN; Uric Acid \>1.2 x ULN; Cholesterol \>1.3 x ULN; Low density lipoprotein (LDL) cholesterol \>1.2 x ULN; Triglycerides \>1.3 x ULN; Glucose \>1.5 x ULN; Urine Glucose \[qualitative (Qual)\] \>=1; Urine Protein (Qual) \>=1; Urine Blood/Hemoglobin (Hgb) (Qual) \>=1.

Number of Participants With Clinical Significant Electrocardiogram (ECG) Changes
Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months

Clinically significant ECG findings included: corrected QT (QTc), QT interval corrected using the Bazett's formula (QTcB), and QT interval corrected using the Fridericia formula (QTcF)\> 450 millisecond (ms), \>480 ms, and \>500 ms respsctively, change from baseline in QTc, QTcB, and QTcF \>= 30 ms, and \>= 60 ms, respectively.

Number of Participants With no at Baseline and Yes at Any Post Baseline for Columbia Suicide-Severity Rating Scale (C-SSRS) According to the Columbia Classification Algorithm of Suicide Assessment (C-CASA) Categories
Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months

C-SSRS is a participant rated questionnaire to assess suicidal ideation, suicidal behavior, actual attempts (yes or no responses), and intensity of ideation (rated 1=low severity to 5=high severity). Yes/No responses are mapped to Columbia Classification Algorithm of Suicide Assessment (C-CASA) categories: Completed suicide, suicide attempt, preparatory acts toward imminent suicidal behavior, suicidal ideation, and self-injurious behavior, or no suicidal intent. A participant could have a yes or no response in more than one category.

To evaluate the improvement of social function following therapy with Venlafaxine extended release (XR)in the Treatment of Panic Disorder in comparison to Paroxetine.
Final on therapy Social Anxiety Scale-Adolescents and Children (SAS-AC) total score.
Postdose QTcF (Fridericia's correction) intervals
0 to 24 hours
