Three sessions of 3,4‐methylenedioxymethamphetamine (MDMA)‐assisted therapy over 3 months significantly improved symptoms of post‐traumatic stress disorder (PTSD) compared with placebo plus therapy in a Phase 3 trial. MDMA‐assisted therapy also resulted in improvement in a measure of functional impairment. Study results were published online Sept. 14, 2023, in Nature Medicine.

A single 25‐mg dose of psilocybin administered with psychological support led to significant and sustained improvement in depressive symptoms compared with placebo in a Phase 2 study of patients with major depressive disorder. A higher number of adverse events occurred in the psilocybin group, but no serious treatment‐emergent adverse events were reported. Study results were published online...

Ongoing antidepressant treatment is believed to alter the psychedelic effect of psilocybin, so most psilocybin trials have required withdrawal from antidepressants before enrollment. There has been recent evidence, however, that administration of a selective serotonin reuptake inhibitor (SSRI) does not significantly alter the acute subjective effects of psilocybin. A Phase 2 open-label trial...

Vitamin D3, omega-3s show no protection against late-life depression Some older adults with subthreshold depression or at high risk for depression might have elevated inflammation or poor vascular and metabolic health, suggesting that supplementation could improve mood in these individuals. An ancillary study to a trial of vitamin D3 and omega-3 fatty acids examined the effects of these...

A large‐scale open‐label trial conducted at electroconvulsive therapy (ECT) clinics has found that twice‐weekly dosing of ketamine was noninferior to three sessions a week of ECT in patients with treatment‐resistant major depression. Relapse rates during a 6‐month follow‐up period after the initial 3‐week treatment period were higher among patients receiving ECT than patients receiving...

Interim results from a Phase 3 study of esketamine nasal spray in patients with treatment‐resistant depression showed no emerging safety concerns and sustained improvement in depressive symptoms. Nearly half of study participants met criteria for remission at the end of the study's optimization/maintenance phase, the investigators reported. Study results were published online May 12, 2023, in...

The infusions were well-tolerated, with no serious adverse events. Most of the findings were suggestive but not statistically significant. Post-infusion scores on the primary outcome decreased more in the ketamine group than in the midazolam group. The greatest...

Results of a systematic review and meta‐analysis comprising six clinical trials suggest that electroconvulsive therapy (ECT) is more efficacious than ketamine in reducing the severity of depressive symptoms in patients with a major depressive episode. No significant between‐group differences in the prevalence of adverse events were observed. Results of the meta‐analysis were published online...

The effort to identify alternative treatments for anxiety has led to research into the potential of lysergic acid diethylamide (LSD) in reducing anxiety symptoms. Based on results of a placebo‐controlled pilot study showing that two high doses of LSD in patients with a life‐threatening illness resulted in reductions in anxiety for up to 2 months, investigators conducted a Phase 2 study to...

Adults with treatment‐resistant depression who received a single 25‐mg dose of psilocybin saw significant improvement in depressive symptoms relative to a control dose at 3 weeks, a Phase 2b trial has found. A smaller 10‐mg dose of psilocybin did not result in significant improvement over the control dose of 1 mg, and adverse events were common in both of the higher‐dose groups. Study results...

Classic psychedelic drugs such as psilocybin have been associated with reduced depressive symptoms when used as an adjunct to therapy, but concern remains over the potential for adverse events such as seizures when these drugs are used outside controlled clinical settings. A study used a survey of U.S. adults to examine the association between use of classic psychedelics and seizures. The...

Two sessions of psilocybin‐assisted psychotherapy resulted in reduced heavy‐drinking days and other alcohol‐related problems relative to placebo plus psychotherapy in a randomized trial involving patients with alcohol use disorder (AUD). There were no serious adverse events associated with psilocybin administration, and no signs of psychotic disturbances. Study results were published online...

A medication combining dextromethorphan and bupropion was more efficacious than an active comparator and placebo in reducing depressive symptoms in adults with major depressive disorder, a pair of trials has found. Remission rates with dextromethorphan‐bupropion separated from the comparator and placebo by week 2 of treatment in each study, according to researchers. Results of the Phase 2 trial...

In healthy adults, LSD produces little change in cognition, mood There have been numerous anecdotal reports of beneficial mood and cognitive effects from repeated administration of low doses of lysergic acid diethylamide (LSD) at intervals of 3 to 4 days, but few controlled studies have been conducted. Animal research has suggested that repeated low doses of LSD could confer antidepressant...

Extending adjunctive treatment with esketamine nasal spray over 4 weeks showed benefit in a group of patients with treatment‐resistant depression who did not respond within the first week of treatment, a post hoc analysis of two Phase 3 studies has found. The results suggest that a full 4‐week induction of esketamine with an oral antidepressant may optimize treatment outcomes, the researchers...

Although research findings to date do not support the use of psychedelic compounds in the treatment of psychiatric disorders, the existing body of research justifies continued investigation, a literature review concludes. The review found the most significant evidence supporting use of psilocybin and 3,4‐methylenedioxymethamphetamine (MDMA). Both of these drugs have been given “breakthrough...
