Inclusion criteria: Demographic • Men and women between 21 and =65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: Demographic • Patient has history of transmeridian travel (across > 3 time zones) or shift work (permanent night shift or rotating day/night shift work) within past 2 wks or will have to travel (across > 3 time zones) at any time during the study. Diagnostic • Patient’s current depressive episode is his/her first major depressive episode. • Patient has a current primary diagnosis (ie, a diagnosis designated by the investigator as the primary source of current distress and functional impairment) of an Axis I disorder other than MDD. • Patient has a lifetime diagnosis of bipolar disorder, schizophrenia, schizoaffective disorder, or other psychotic disorder, as determined by the investigator. Note that a history of psychotic features in the context of a previous depressive episode is permitted; however psychotic features associated with the current episode are exclusionary. • Patient has a known or suspected personality dysfunction that could, in the investigator's opinion, interfere with trial participation or efficacy evaluation. A patient with known antisocial or borderline personality disorder should be excluded. • Patient has a diagnosis of mental retardation, a history of traumatic brain injury causing ongoing cognitive difficulties, Alzheimer's Disease or another form of dementia, or any chronic organic disease of the central nervous system. • Patient is at imminent risk of self-harm, based on clinical interview and responses on the Columbia Suicidality Severity Rating Scale (C-SSRS), or of harm to others in the opinion of the investigator. Patients must be excluded if they report suicidal ideation with intent, with or without a plan (i.e., MADRS item 10 = 3 and/or Type 4 or 5 on the C-SSRS) in the past 1 month or suicidal behavior in the past 6 months. • Patient currently (within the past year) meets criteria for alcohol or other substance abuse or dependence (excluding nicotine), posttraumatic stress disorder (PTSD), obsessive compulsive disorder (OCD), or eating disorder. • Patient has a positive screening urine drug screen (e.g., positive for benzodiazepines, cannabinoids, cocaine, etc.).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: (1) To evaluate the efficacy of MK-6096 in comparison with placebo as treatment augmentation for patients with MDD, based on change from baseline to week 6 in MADRS total score. (2) To assess the safety and tolerability of MK-6096 as augmentation therapy for patients with MDD. ;Secondary Objective: The secondary objectives are to assess the efficacy of MK-6096 in comparison with placebo as treatment augmentation for patients with MDD, based on the following: 1. Change from baseline to week 6 in the MADRS total score excluding the sleep item; 2. Change from baseline to week 6 in the HAM-D Bech subscale score; 3. HAM-D17 remission (HAM-D17 total score = 7) rate at week 6. ;Primary end point(s): Change from baseline to week 6 in MADRS total score;Timepoint(s) of evaluation of this end point: 6 weeks from baseline (randomization) visit | — |
