Brief summary: This study is looking at the efficacy, durability, safety, and tolerability of multiple single doses of Ketamine vs. active placebo for treating patients with treatment resistant depression who are taking an antidepressant that is not working for them.

Detailed description: The primary objective is to investigate whether all doses (0.1 mg/kg, 0.2 mg/kg, 0.5 mg/kg, and 1.0 mg/kg) of ketamine are superior to active placebo (midazolam 0.045 mg/kg) therapy in the acute treatment of patients with treatment resistant depression within 72 hours (Day 3), when added to ongoing and stable antidepressant therapy.

Eligibility criteria: Inclusion Criteria:

* Male or female, 18-70 years old.

* Has a history of TRD during the current MDE.
* Meet the threshold on the total MADRS score of greater than or equal to 20 at both screening and baseline visits (Day -7/-28 and Day 0), as confirmed by the remote centralized MGH CTNI rater between the screen visit and the baseline visit.
* In good general health
* For female participants, status of non-childbearing potential or use of an acceptable form of birth control
