How Cybin aims to maximize the potential of two classical psychedelics 

Classical psychedelics can be agents of chaos. In sufficient doses, they can trigger experiences of ego death or dissolution, as researchers have noted since the 1960s. Psychedelics can also help promote neural plasticity and uproot negative patterns to treat challenging-to-treat mental health disorders. FDA has acknowledged the potential of psilocybin for mental health by twice granting Breakthrough Therapy Designation status to the compound as a potential therapy for serious depression. 

The startup Cybin (Toronto, Canada) aims to harness the therapeutic potential of psychedelics while minimizing possible adverse side effects. 

Cybin’s deuterated psilocybin analog CYB003 could treat major depressive disorder (MDD) and alcohol use disorder (AUD) while potentially being better tolerated than traditional psilocybin. 

CYB003 is the company’s first focus as psilocybin is the most studied psychedelic molecule in academic studies “with decad…

How psychedelics could address unmet need in mental health

Interest in the therapeutic potential of psychedelics is booming, given their therapeutic potential for treating depression and other conditions. It is telling that psychedelics were among the hottest topics at the World Economic Forum (WEF) meeting this year in Davos, Switzerland, prompting mockery from late-night comics. 

Although the field remains embryonic, part of the reason for the recent interest in psychedelics is their potential to address difficult-to-treat mental health conditions. For example, research such as the U.S. government-backed Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study “showed us that our available medications are not as effective as we’d hoped they would be,” said Dr. John Krystal, chair of the department of psychiatry at Yale University, in a recent webinar from Cybin (Toronto, Canada). For depressed who respond to s…

Psilocybin holds therapeutic promise — but tapping its potential could be a challenge

A growing number of small studies indicate that psilocybin, a psychoactive compound in hallucinogenic mushrooms, holds promise for treating depression, addiction and anxiety.

But while traditional psychedelics like psilocybin may have broad potential, making effective therapeutic use of them at scale is likely to be challenging in the near term, said psilocybin advocate Derek Chase, who has experience working in the pharmaceutical, cosmetic and cannabis industries.

“The mental health segment needs to be readdressed from the ground up” to make the most of psychedelics, Chase said. With psychedelics, the mental health industry should strive to find a “true linking of medication with therapy.”

Psychedelics such as psilocybin should …

Psilocybin lit up the brains of people with severe depression in small study

A British study enrolling 43 people with severe depression found that the magic mushroom compound psilocybin bested the antidepressant Lexapro (escitalopram).

The blinded study published in Nature tracked patients’ symptoms and used functional magnetic resonance imaging (fMRI) to measure the brain’s metabolic function.

Those who received psilocybin weeks showed significant and sustained reductions in depressive symptoms, while fMRI scans showed prominent neural activity throughout the brain that lasted three weeks. In addition, the brain activity of psilocybin recipients was similar to that of a healthy brain.

Conversely, those who received Lexapro had a slight improvement in symptoms and neural activity that continued to be limited to defined brain regions.

Last year, a small Phase 2 study published in NEJM found that psilocybin…

Ninth Circuit tosses psilocybin case for lack of jurisdiction

A three-judge panel on the Ninth U.S. Circuit Court of Appeals refused to hear a lawsuit filed by Dr. Sunil Aggarwal, a hospice physician, and two cancer patients who sought psilocybin, a Schedule I drug, to treat anxiety and depression in terminally ill patients.

Aggarwal’s employer, the Advanced Integrative Medical Sciences (AIMS) Institute, had sought access to use a synthetic form of the psilocybin under the Right to Try Act and similar laws, which allows unapproved treatment options for those with life-threatening diseases or those unable to obtain novel treatments in clinical trials.

The Drug Enforcement Agency (DEA) argued in a letter to AIMS that right-to-try laws do not preempt the Controlled Substances Act (CSA).

A three-judge panel on the Ninth determined the letter from the DEA did not represent formal guidance and, therefore, the Court lacked jurisdictio…

Why Tryp Therapeutics is exploring the use of psilocybin to treat chronic pain

Many researchers are exploring the potential of the psychedelic compound psilocybin to treat conditions such as depression and post-traumatic stress disorder.

But psilocybin offers broader therapeutic promise as it appears to spur neuroplasticity, according to Greg McKee, CEO of Tryp Therapeutics (San Diego).

The company is exploring the use of psilocybin-based drugs for treating eating disorders and chronic pain.

“There’s a lot of similarities mechanistically in terms of how psilocybin works to treat depression that we think could apply to treating pain,” McKee said.

Tryp is working with researchers who believe psilocybin can support neuroplasticity in a manner that reduces chronic pain. Tryp’s research partners believe psilocybin can help correct abnormal neural firing in patients with chronic pain and related conditions.

Tryp Therapeutics announces research alliance with the University of Michigan 

La Jolla, Calif.–based Tryp (CSE: TRYP) is tapping the University of Michigan to test its TRP-8803 drug formulation against traditional oral formulations of synthetic psilocybin.

The psilocybin-based drug developer will also work with the university to compare TRP-8803 with conventional formulations of synthetic psilocybin. In particular, the university will perform pharmacokinetic analysis for blood samples from patients who received psilocybin via oral and novel delivery methods.

Additionally, Tryp expects the partnership with the University of Michigan to help advance TRP-8803 to Phase 2b clinical trials. The research alliance will explore the psilocybin-induced increase in neurophysiological complexity and psilocybin’s potential to reduce chronic central pain. The University of Michigan also will explore the impact of alternative delivery strategies of psilocybin on pain indices and insular glutamate and gamma-aminobutyric acid (GABA) levels.
