Brief Summary:

This multi-centre study will follow a randomised, double-blind, parallel-group, active-controlled design and will evaluate the efficacy, safety and tolerability of bupropion extended-release (XL) (300 mg/day) compared with escitalopram (10-20 mg/day) in outpatients and inpatients with major depressive disorder (MDD). The total duration of the study will be 11 weeks consisting of three phases. The screening phase (phase I) will be lasting for 0-14 days, subjects will be randomised to bupropion XL or escitalopram in a 1:1 ratio for acute phase treatment phase (phase II) for 8 weeks. There are 3 dose levels during this acute treatment phase. The 3-dose level plan is designed to ensure each drug is titrated according to the prescribing information and to reach an optimal clinical dose. Finally patients will enter the taper phase (phase III) for up to 1 week to assess and reduce the possible withdrawal symptoms.

In China almost all existing antidepressants are available on the market, but bupropion XL has not yet been approved. This Phase III clinical trial will be used for the purpose of registering bupropion XL in China.

Primary Outcome Measures :
  1. Mean Change in Hamilton Depression Rating Scale - 17 (HAMD-17) Total Score From Baseline to End of Acute Treatment Phase (Week 8) [ Time Frame: Baseline (Week 0) and Week 8 ]
    HAMD-17 is used to assess the severity of depression and symptom improvement. It consisted of 17 questions. The HAMD-17 total score is calculated by summing the individual response scores if there is no missing response. HAMD-17 has a total score in a range of 0 (not present) to 52 (severe). Change from Baseline was calculated by subtracting the Baseline total score (at Day 0, Week 0) from Week 8 observed total score. The Per Protocol (PP) Population is defined as all randomized participants in the Intent-To-Treat (ITT) Population who do not meet criteria of a major protocol deviation, with overall compliance of active drug for acute treatment phase in the range of 75%-125% and complete the first 6 weeks treatment and has HAMD-17 assessment at/after week 6 (that is >=35 days). All participants in the PP population were included in the mixed model repeated measures analysis. Only those participants with data available at the specified time point were analyzed.


Secondary Outcome Measures :
  1. Response Rate Based on HAMD-17 Total Score [ Time Frame: Up to Week 8 ]
    HAMD-17 is an extensively used tool to assess the severity of depression and symptom improvement during the treatment. The HAMD-17 adopted for this study consisted of 17 questions with multiple choice responses, each of which is numerically scored. The HAMD-17 total score is calculated by summing the individual response scores if there is no missing response. HAMD-17 has a total score in a range of 0 (not present) to 52 (severe). Values at Day 0, Week 0 was considered as Baseline value. Response was defined as decrease in HAMD-17 total scores at end of acute treatment phase (Week 8) relative to Baseline by at least 50%. Non-responder Imputation was used in calculation of rates.

  2. Remission Rate Based on HAMD-17 Total Score [ Time Frame: Up to Week 8 ]
    HAMD-17 is an extensively used tool to assess the severity of depression and symptom improvement during the treatment. The HAMD-17 adopted for this study consisted of 17 questions with multiple choice responses, each of which is numerically scored. The HAMD-17 total score is calculated by summing the individual response scores if there is no missing response. HAMD-17 has a total score in a range of 0 (not present) to 52 (severe). Values at Day 0, Week 0 was considered as Baseline value. Remission was defined as HAMD-17 total scores at end of acute treatment phase (Week 8) <=7.

  3. Sustained Response Rate Based on HAMD-17 Total Score [ Time Frame: Up to Week 8 ]

The HAMD-17 total score is calculated by summing the individual response scores if there is no missing response. HAMD-17 has a total score in a range of 0 (not present) to 52 (severe). Values at Day 0, Week 0 was considered as Baseline value. Sustained response was defined as response at end of acute treatment phase and an earlier visit and the decrease from Baseline in non-missing HAMD-17 total scores at all visits between these two visits by at least 40%.

  4. Sustained Remission Rate Based on HAMD-17 Total Score [ Time Frame: Up to Week 8 ]
    HAMD-17 is an extensively used tool to assess the severity of depression and symptom improvement during the treatment. The HAMD-17 adopted for this study consisted of 17 questions with multiple choice responses, each of which is numerically scored. The HAMD-17 total score is calculated by summing the individual response scores if there is no missing response. HAMD-17 has a total score in a range of 0 (not present) to 52 (severe).

    MADRS is a 10-point rating scale. Each item is scored on a scale of 0-6, with a total score range of 0-60. Higher score indicates worst symptoms. This scale is mainly used to assess the efficacy of antidepressant treatment. The ratings were based on the signs and symptoms during the preceding week prior to the visit.

    For CGI-I rating, the raters indicated their assessment of the participant's total improvement or worsening compared to the participant's condition at the Baseline visit, whether or not the improvement or worsening was thought to be treatment related. Scores ranges from 0 to 7 where 0 represents "Not assessed", and the remaining values 1-7 represent "Very much improved" (1) to "Very much worse" (7). Participants with score 0 were excluded from analysis. All participants in the PP population were analyzed and n=X in the category titles represented the number of participants with data available at the specified time points.
