Trial overview
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
Trial description: 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.

- Female patients of child-bearing potential only: patients must not be lactating and must test negative for pregnancy at screening and agree to use a medically accepted method of birth control during the study.
- Liver function tests: alanine aminotransferase (ALT) <2x upper limit of normal (ULN); alkaline phosphatase and bilirubin <=1.5xULN (isolated bilirubin >1.5 x ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Corrected QT (QTc) criteria： QTc <450 milliseconds (msec) or QTc <480msec for patients with bundle branch block. The QTc is the QT interval corrected for heart rate according to either Bazett’s formula (QTcB), Fridericia’s formula (QTcF), or machine or manual overread. For subject eligibility and withdrawal, QTcF will be used. For purpose of data analysis, QTcF will be used. The QTc should be based on single or averaged QTc values of triplicate electrocardiograms (ECGs) obtained over a brief recording period.
Exclusion criteria:
