Ketamine and esketamine show no adverse cognitive effects

A systematic review of medical research has shown that ketamine and esketamine show no adverse cognitive effects in treatment-resistant depression.

The review of medical research has shown that both ketamine and esketamine have no adverse effects on memory, attention or other cognitive processes. According to the findings, some cognitive functions improved seven to 13 days after repeated ketamine infusions.

The review has been published in the Harvard Review of Psychiatry.

Cognitive safety

Ketamine, which is a widely used surgical anaesthetic, has been shown to have rapid antidepressant effects at low doses, and esketamine, a variation of the drug, has recently been approved for depression treatment. Although ketamine is not yet approved for treatment of depression, some physicians prescribe it for the condition on an “off-label” basis. 

Despite offering promise as a treatment, there are potential safety concerns with ketamine such as memory impairment after long-term recreational use of ketamine, as well as in medical studies in which healthy volunteers received just one infusion. Such problems, and other cognitive symptoms, are a key aspect of major depressive disorder.

According to the new research, led by Breno Souza-Marques, BA, and Lucas C. Quarantini, MD, PhD, of Federal University of Bahia, Salvador, Brazil: “Current evidence suggests that ketamine and esketamine do not appear to exert significant deleterious neurocognitive effects in treatment-resistant depression.”

For the review, 14 studies were identified that collectively involved 1,019 patients: one study of esketamine nasal spray for 44 weeks, seven studies of a single ketamine intravenous infusion, and six studies in which patients received six ketamine infusions over two or three weeks.

The esketamine study showed no changes in cognitive performance, where as five studies of ketamine reported improvements in memory, processing speed, or cognitive flexibility. Only one of the 14 studies reported cognitive impairment after ketamine treatment. 

Memory was worse 24 hours after six ketamine infusions, and processing speed was worse 24 hours after a single infusion, but these deficits were no longer present seven days after treatment. 

The researchers noted: “Results suggest possible neuropsychological profiles predictive of antidepressant response to ketamine, such as lower attention, slower processing speed, or higher working memory, that should be further assessed in future studies, as these results could provide time-saving evidence to clinicians and mental health practitioners.”

The review highlights that, despite this encouraging evidence, further studies are needed to assess the longer-term neurocognitive effects of the drugs.

Psychedelic therapy programmes launch to address heartbreak, burnout and more

Mindbloom has launched its new Mastermind Series of psychedelic programmes for overcoming heartbreak, burnout and other unique mental health challenges. 

Led by and developed with leading experts in the field, each programme combines specialised teachings with ketamine therapy.

All programmes will include six ketamine therapy sessions focusing on a specific mental health issue, expert-led audio, video, and written content for preparation, treatment, and integration, practical tools such as meditation, one-on-one coaching and group integration sessions.

The first programme in the Series is ‘Recovering from Rejection and Failure’, led by Dr Guy Winch who is a leading authority on emotional health, and a best-selling author and TED speaker whose talks have received over 30 million views.

Winch’s programme focuses on healing and preventing emotional injuries that people suffer in their personal, professional and romantic lives.

Mindbloom CEO and Founder Dylan Beynon stated: “More than 100 studies and 20 plus years of clinical use show that ketamine therapy may be the most transformational mental health treatment available today.

“In the face of epidemics of mental illness, addiction, and loneliness, we’re thrilled to offer our clients access to top experts across a range of issues – and to pair their expertise with our best-in-class ketamine therapy honed over hundreds of thousands of treatment sessions.”

“Emotional wounds like rejection and failure can be even more devastating than physical wounds, yet we don’t give them the same time and attention,” added Dr Winch.

“I’m thrilled to combine my techniques for emotional first aid with ketamine therapy, which has been shown to increase neuroplasticity and help build emotional resilience.”

Additional Mastermind programmes will be released in the coming months, including: Getting Unstuck, by Dr Elizabeth Lombardo; Beating Burnout, by Dr Shauna Shapiro; and Coping with Cravings, by Dr Jud Brewer

“Americans are struggling with heartbreak, burnout, and other challenges every day, and they’re looking for new tools to address them,” said Mindbloom’s Medical Director Dr Leonardo Vando.

“I’m grateful to these experts for providing Mindbloom’s clients with the unique practices and insights they’ve cultivated during their distinguished careers, to help them overcome the biggest obstacles in their lives.”

Psilocybin analogue shows positive results in Phase 2 depression study

Psilocybin analogue shows positive results in Phase 2 depression study

Cybin has announced positive Phase 2 topline safety and efficacy data for its proprietary deuterated psilocybin analogue – CYB003 – for the treatment of major depressive disorder (MDD).

Results from Cybin’s study have shown that 79% of patients were in remission from depression at six weeks after receiving two doses of CYB003.

CYB003 demonstrated a large improvement in symptoms after one dose and a total of 79% of patients were responsive to the treatment. The compound also demonstrated an excellent safety profile in doses tested, with all reported adverse events mild to moderate and self–limiting.

Additionally, Cybin has stated that the magnitude of improvement was superior compared to approved antidepressants and recently reported data with other psychedelics, stating that the effects translate into an unprecedented effect size.

The company has said that the results compare favorably to pooled data from 232 industry studies of current standard-of-care antidepressants, SSRIs, submitted to the FDA.

The announcement follows Phase 2 interim results in early November 2023, which demonstrated that CYB003 saw a “rapid, robust and statistically significant reduction in symptoms of depression three weeks following a single 12mg dose compared to placebo”.

Cybin CEO, Doug Drysdale, stated: “We are delighted to share that CYB003 achieved the primary efficacy endpoint in this study and showed rapid and statistically significant improvements in depression symptoms after a single dose, with a clear incremental benefit of a second dose, resulting in four out of five patients in remission from their depression at six weeks.

“This is an impressive finding and follows on from the unprecedented interim results we announced earlier this month.”

Drysdale emphasised that the strength of the data will support CYB003 into Phase 3 of the study.

Cybin CMO, Amir Inamdar, added: “The significant reduction in depression symptoms observed in our Phase 2 study is highly gratifying.

“At the three-week primary efficacy endpoint, a single 12mg dose of CYB003 showed a rapid, robust, and highly statistically significant improvement in depression symptoms compared to placebo, with a -14.08 point difference in change from baseline in MADRS. 

“This translated into a very large effect size. Similar significant and robust effects were also seen with a single 16mg dose, which resulted in an improvement in symptoms of depression as measured using the MADRS total score by about 13 points versus placebo. 

“These effects were evident on day one with the 16mg dose and were also highly statistically significant. When data from 12mg and 16mg are pooled, these robust effects are maintained. Further, with two doses, response and remission rates in excess of 75% were observed with CYB003 (12mg). 

“With these findings in hand, we are encouraged by the potential of CYB003 to help those with MDD and look forward to progressing to a multinational, multisite Phase 3 study early next year.”

Cybin is planning on submitting topline data to the FDA with an aim to hold a Phase 2 meeting in Q1 of 2024, with further 12-week durability data from Phase 2 CYB003 expected in Q1, and recruitment for the Phase 3 study anticipated to begin by the end of Q1 2024.
