Inclusion Criteria

Subjects must have the ability to comprehend the key components of the consent form.

Male or female outpatients aged 18-64, inclusive.

3A primary diagnosis of MDE associated with MDD, single episode or recurrent, according to DSM-IV-TR (296.2 or296.3), diagnosed through a comprehensive psychiatric evaluation [in conjunction with the Mini International Neuropsychiatric Interview (MINI), Clinician Rated Version 5.0], as assessed by a physician with adequate training in psychiatry (e.g. Board Certified psychiatrist).

Subjects must, in the investigator’s opinion based on the subject’s history, have met DSM-IV-TR criteria for their current MDE for at least 8 weeks prior to the Screening Visit.

Subjects with a Carroll Depression Scale-Revised (CDS-R) self-assessment total score of less than or equal to 24 at the Screen Visit and Baseline Visit.

Subjects must have a CGI- Severity of Illness score = 4 at the Baseline Visit.

Subjects with a history of peptic ulcer disease (PUD) with a known etiology must provide documentation by a gastroenterologist of the etiology of the PUD and that effective treatment was provided with full eradication of ulcers and symptoms. For such subjects appropriate steps must also have been taken to minimize reoccurrence risk (i.e. if PUD was nonsteroidal anti-inflammatory drug [NSAID] induced, the subject should no longer be taking NSAID medications; if cause was H. pylori, the subject should have been appropriately treated).

Women of childbearing potential must commit to consistent and correct use of an acceptable method of birth control; GSK acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of a physician, are as follows:
a)Non-childbearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is post-menopausal. For purposes of this study, postmenopausal is defined as one year without menses)
b)Child-bearing potential, has a negative serum pregnancy test result at screen and a negative urine dipstick pregnancy test at baseline (prior to study drug administration), and agrees to one of the following:
•Male partner who is sterile prior to the female subject's entry into the study and is the sole sexual partner for that female subject
•Oral contraceptives (either combined or progestogen only) with double-barrier method of contraception consisting of spermicide with either condom or diaphragm
•Double-barrier method of contraception consisting of spermicide with either condom or diaphragm
•IUD with a documented failure rate of less than 1% per year
•Complete abstinence from intercourse for two weeks before exposure to the investigational product, throughout the clinical trial, and for a period after the trial to account for elimination of the drug (minimum of three days, equivalent to five half lives)
c)If subjects indicate they will remain abstinent during the period described above, they must agree to follow GSK guidelines for the consistent and correct use of an acceptable method of birth control should they become sexually active.

Subjects maintained on thyroid medication must be euthyroid for a period of at least 6 months prior to the Screening Visit
Subjects have any screening electrocardiography (ECG) parameter outside of the
Sponsor-specified ranges

be clinically significant and not resolved by the Baseline Visit
Subjects with active PUD and/or history of PUD of an unknown etiology
Subjects with a screening serology test that is positive for H. pylori
Subjects who will likely require the use the following medications:
