OBJECTIVE: The authors compared the efficacy of standard-of-care treatment plus intranasal esketamine or placebo for rapid reduction of symptoms of major depression, including suicidality, among individuals at imminent suicide risk. METHOD: In a double-blind, multicenter, proof-of-concept study, 68 participants were randomly assigned to receive esketamine (84 mg) or placebo twice weekly for 4...

Patients with treatment‐resistant depression who received intranasal esketamine as adjunctive therapy with an antidepressant experienced greater symptom improvement than patients receiving adjunctive placebo, a multiphase study with 67 participants has found. The antidepressant effect seen in the study was dose‐related, and adverse events led to study discontinuation in only a small number of...

Abstract Background Recognizing the importance not only of the clinician’s opinion but also of the patient’s experience and perspective, Sequenced Treatment Alternatives to Relieve Depression (STAR*D) utilized both clinician-reported and patient-reported outcomes in a large-scale multi-step study on antidepressant effectiveness in real-world settings. Both approaches indicate that <17% of Major...

Rationale: The mechanisms responsible for the unique antidepressant properties of ketamine have only been partly resolved. Recent preclinical reports implicate the neurotransmitter serotonin [5-hydroxytryptamine (5-HT)] in the antidepressant-like response of ketamine, and modulation of 5-HT1B receptors has been hypothesized to attain an important role. Objectives: To evaluate the role of...

Importance: Approximately one-third of patients with major depressive disorder (MDD) do not respond to available antidepressants. Objective: To assess the efficacy, safety, and dose-response of intranasal esketamine hydrochloride in patients with treatment-resistant depression (TRD). Design, Setting, and Participants: This phase 2, double-blind, doubly randomized, delayed-start,...

There is a great unmet need for new medications with novel mechanisms of action that can effectively treat patients who do not benefit from standard antidepressant therapies. After a period in which it seemed as if the pharmaceutical pipeline for new antidepressants was going dry, the past decade has witnessed renewed interest, beginning with discovery of the antidepressant effects of ketamine....

Background: The neurovascular plasticity of hippocampus is an important theory underlying major depression. Ketamine as a novel glutamatergic antidepressant drug can induce a rapid antidepressant effect within hours. In a mechanistic proof of this concept, we examined whether ketamine leads to an increase in synaptogenesis and vascularization within 24 hours after a single injection in a...
