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.
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.
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.
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.
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.
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.

Effexor is used for the treatment of depression, including major depressive disorder. It is a small molecule psychiatry therapy developed by Pfizer, Inc. Clinical development has focused on major depression, with studies conducted in adult and elderly patient populations.
Effexor is developed and manufactured by Pfizer, Inc., which trades on the New York Stock Exchange under the ticker PFE. Pfizer is the company behind the Effexor and Effexor XR brands.
Yes, Effexor XR is an alternative name for Effexor. The extended-release formulation is referred to as Effexor XR, and the two names refer to the same Pfizer antidepressant product. People searching for either name are looking at the same drug.
Effexor has been studied in Phase 3 clinical development for depression. Three Phase 3 trials have been completed, and none are currently active. The program enrolled a total of 840 patients across those completed studies.
Effexor has been evaluated in three completed Phase 3 trials: NCT00225511, which studied Effexor XR for major depression in 590 patients; NCT00225524, a long-term safety study in 150 patients; and NCT00225485, which studied Effexor XR in elderly patients with major depression in 100 patients. All three were conducted in Japan.
The Effexor Phase 3 depression trials enrolled adults aged 20 years and older, with one study restricted to elderly patients aged 65 years and older. All three trials were conducted in Japan, enrolled both sexes, and did not include healthy volunteers.
