About this study
Official title: A Multi-centre, Randomised, Double-blind, Parallel Active-controlled Study Evaluating the Efficacy, Safety and Tolerability of Bupropion Hydrochloride Extended-release (Bupropion XL 300mg Once Daily), Escitalopram Oxalate (Escitalopram, 10mg-20mg Once Daily) in Subjects With Major Depressive Disorder
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Change in Hamilton Depression Rating Scale - 17 (HAMD-17) Total Score From Baseline to End of Acute Treatment Phase (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.
Measured: Baseline (Week 0) and Week 8

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

| Bupropion Treatment Arm | Experimental | Drug: Bupropion, Drug: Escitalopram Matching PlaceboSubject will receive bupropion in 3 dose levels along with escitalopram matching placebo to maintain the blind in acute treatment phase. At dose level 1 (Week 0 to Week 1), Subjects will receive bupropion XL 150 milligram (mg) per day for a week. At dose level 2 (Week 1 to Week 4), bupropion XL dose will be increased to 300mg/day for further 3 weeks. At dose level 3 (Week 4 to Week 8), bupropion XL dose will be maintained at 300mg/day. Subjects intolerable to dose level 3 will be allowed to down titrate to dose level 2 at anytime, and maintain the dose until the end of acute treatment phase (Week 8, Visit 7). At the end of acute treatment phase, the dose of bupropion XL will be reduced to 150mg/day for 1 week before discontinuation. |
| Escitalopram Treatment Arm | Active comparator | Drug: Bupropion Matching Placebo, Drug: EscitalopramSubject will receive escitalopram in 3 dose levels along with bupropion matching placebo to maintain the blind in acute treatment phase. At dose level 1 (Week 0 to Week 1), Subjects will receive escitalopram 10mg/day for a week. At dose level 2 (Week 1 to Week 4), escitalopram dose will be maintained at 10mg/day for further 3 weeks. At dose level 3 (Week 4 to Week 8), escitalopram dose will be increased to 20mg/day. Subjects intolerable to dose level 3 will be allowed to down titrate to dose level 2 at anytime, and maintain the dose until the end of acute treatment phase (Week 8, Visit 7). At the end of acute treatment phase, the dose of escitalopram 20mg/day, the dose will be reduced to 10 mg/day for 1 week before discontinuation, while those receiving 10mg/day will discontinuation directly. |

Primary outcome
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.
