Abstract

Introduction: Mental illness has a chronic course of illness with a number of clinical manifestations. Affected individuals experience significant functional, emotional, cognitive, and/or behavioral impairments. The growing prevalence of mental illness has been associated with significant social and economic costs. Indeed, the economic burden of mental illness is estimated to exceed $1.8 trillion USD over the next 30 years. A significant number of individuals affected by mental illness fail to respond to first-line treatment options. Therefore, there remains an unmet need for rapidly attenuating therapeutic options for mental health disorders with minimal social and economic burden.

Areas covered: The paucity of novel treatment options warrants a renewed investigation of psychedelic-based psychotherapy. Herein, the authors will evaluate the therapeutic potential of traditional psychedelics, psilocybin, and MDMA, in the treatment of mental illness with a narrative review of available literature.

Expert opinion: Psychedelics, such as psilocybin and MDMA, offer an alternative avenue of therapy for many mental health disorders. Available evidence indicates that psychedelics may offer a single-dose, rapid effect model that have robust effects with treatment-resistant mental disorders and a unique advantage as a possible monotherapy for mental illness. Novel clinical trials that evaluate the safety, tolerability, and efficacy in clinically representative populations are warranted.

Abstract

As interest has grown in the potential psychiatric applications of ketamine, the number of registered clinical trials has grown substantially. Herein, we summarize and analyze clinical trials registered with ClinicalTrials.gov that assess the treatment of any psychiatric disorder with ketamine or ketamine enantiomers (e.g., S-ketamine, R-ketamine), with a focus on ongoing clinical trials. A ClinicalTrials.gov search on February 21, 2020 returned 140 registered trials. Frequency data was analyzed to determine the distribution of study designs. The majority of trials (70%) investigated the therapeutic effect of ketamine in mood disorders (unipolar: 60%, bipolar: 0.7%, both: 5.7%). Suicidal ideation (13.1%), post-traumatic stress disorder (5.4%), and obsessive-compulsive disorder (3.6%) were also investigated. Intravenous (IV) administration was the most common route with 87% of the studies using IV ketamine. Single-dose studies represented 50% of IV ketamine studies. Few studies were assessing maintenance treatment. Most studies were phase I or II with few definitive phase III trials registered. Given the large number of ongoing studies assessing psychiatric application of ketamine, researchers and relevant stakeholders should consider not only completed, published studies, but also ongoing registered studies in adjudicating the most relevant research questions. More definitive phase III trials and maintenance studies of IV ketamine for mood disorders are required, as numerous completed and ongoing studies have already assessed and demonstrated the proof-of-concept of acute antidepressant effects in phase I and II trials.
