Adjusted Mean Change From Baseline in the Hamilton Depression Rating Scale (HAM-D; 17 Items) Total Score at Week 8 [ Time Frame: Baseline (Week 0) and Week 8 ] [ Designated as safety issue: No ]
The HAM-D measures the severity of depressive symptoms in participants with major depressive disorder (MDD). It is a checklist of 17 items that are ranked on a scale of 0-4 or 0-2. The range for the total score (which is the sum of the scores of all 17 items) is 0-52; a higher score indicates greater severity of symptoms. Mean change from baseline was calculated as the value at Week 8 minus the Baseline value.
Change from baseline in HAM-D (Hamilton Depression Rating Scale) (17 items) total score to Week 8 (value at Week 8 - value at Week 0) [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

  • Mean Change From Baseline in the HAM-D Total Score at Weeks 1, 2, 3, 4, 6, and 8 [ Time Frame: Baseline (Week 0); Weeks 1, 2, 3, 4, 6, and 8 ] [ Designated as safety issue: No ]
    The HAM-D measures the severity of depressive symptoms in participants with MDD. It is a checklist of 17 items that are ranked on a scale of 0-4 or 0-2. The range for the total score (which is the sum of the scores of all 17 items) is 0-52; a higher score indicates greater severity of symptoms. Mean change from baseline was calculated as the value at each time point minus the Baseline value.
  • Percentage of HAM-D Responders at Weeks 4 and 8 [ Time Frame: Weeks 4 and 8 ] [ Designated as safety issue: No ]
    The HAM-D measures the severity of depressive symptoms in participants with MDD. It is a checklist of 17 items that are ranked on a scale of 0-4 or 0-2. The range for the total score (which is a sum of the scores of all 17 items) is 0-52; a higher score indicates greater severity of symptoms. Responders are defined as participants with a 50 percent or greater reduction from baseline in the HAM-D total score.
  • Percentage of HAM-D Remitters at Weeks 4 and 8 [ Time Frame: Weeks 4 and 8 ] [ Designated as safety issue: No ]
    The HAM-D measures the severity of depressive symptoms in participants with MDD. It is a checklist of 17 items that are ranked on a scale of 0-4 or 0-2. The range for the total score (which is the sum of the scores of all 17 items) is 0-52; a higher score indicates greater severity of symptoms. Remitters are defined as participants with a HAM-D total score of 7 or less.
  • Mean Change From Baseline in the Clinical Global Impression-Severity of Illness (CGI-SI) Scores at Weeks 1, 2, 3, 4, 6, and 8 [ Time Frame: Baseline (Week 0); Weeks 1, 2, 3, 4, 6, and 8 ] [ Designated as safety issue: No ]
    The 7-point CGI-SI scale assesses the clinician's impression of the participant's current illness state. Scores on the CGI-SI range from 1 = not ill at all to 7 = among the most extremely ill. Mean change from baseline was calculated as the value at each time point minus the baseline value.
  • Percentage of Responders Based on the Clinical Global Impression-Global Improvement (CGI-GI) Scores at Weeks 4 and 8 [ Time Frame: Weeks 4 and 8 ] [ Designated as safety issue: No ]
    The 7-point CGI-GI assesses the participant's improvement or worsening from baseline. Scores on the CGI-GI range from 1 = very much improved to 7 = very much worse. Responders are defined as participants with a score of 1 or 2 = much improved.
  • Change from baseline in HAM-D (17 items) total score to Weeks 1, 2, 3, 4, and 6 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Change from baseline in CGI Severity of Illness to Weeks 1, 2, 3, 4, 6 and 8 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Percentage of CGI Global Improvement responders at Weeks 4 and 8 (defined as proportion of subjects 'very much' or 'much' improved) [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Percentage of HAM-D (17 items) responders at Weeks 4 and 8 (defined as >50% reduction from Week 0 HAM-D total score) [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Percentage of HAM-D (17 items) remitters at Weeks 4 and 8 (defined as HAM-D total score <=7) [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Changes in vital signs including: blood pressure, pulse rate, ECG & body weight. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Adverse events type/severity/incidence and "Possibly Suicidality-Related Adverse Events") [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Controlled-release Paroxetine in Major Depressive Disorder (Double-blind, Placebo-controlled Study)
A Randomized, Double-blind, Placebo Controlled Trial to Evaluate the Clinical Effects of Controlled Release Paroxetine in the Treatment of Major Depressive Disorder

This is a randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy of controlled-release (CR) formulation of paroxetine orally administered to patients with major depressive disorder (MDD) at a dose level in the range of 25 - 50 mg/day (initial dose level, 12.5 or 25 mg/day) once daily after evening meal for 8 weeks based on the decrease in HAM-D (Hamilton Depression Rating Scale) total score, to evaluate the safety based on adverse events, laboratory data and vital signs, and to describe the efficacy and safety of immediate release (IR) formulation of paroxetine.
