The objective of the current study is to investigate the safety and efficacy of a single dose of intranasal (IN) ketamine in treatment-resistant depression (TRD).
Major Depressive Disorder
Intervention Model: Crossover Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
||Intranasal (IN) Ketamine in Treatment-Resistant Depression (TRD)
Primary Outcome Measures:
- Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: 24 hours ]
Number of patients meeting response criteria of >=50% decrease in MADRS score from baseline , ie, difference in depressive symptoms using MADRS instrument, 24 hours following drug administration
10-item instrument used for the evaluation of depressive symptoms in adults and for the assessment of any changes to those symptoms. Each of the 10 items is rated on a scale of 0 to 6, with differing descriptors for each item. These individual item scores are added together to form a total score, which can range between 0 and 60 points.
