Mental health disorders, or mental illness, refer to a wide range of disorders that include, but are not limited to, depressive disorders, anxiety and panic disorders, schizophrenia, eating disorders, substance misuse disorders, post-traumatic stress disorder, attention deficit/hyperactivity disorder and obsessive compulsive disorder. The severity of symptoms varies such that some individuals experience debilitating disease that precludes normal social function, while others suffer with intermittent repeated episodes across their lifespan. Although the presentation and diagnostic criteria among mental illness conditions are distinct in part, there are common endophenotypes of note across the diseases, and often comorbidities exist. Specifically, there exist phenotypic endophenotypes associated with alterations in mood, cognition and behavior. Interestingly, many of these endophenotypes extend to neurological conditions as well. For example, attentional deficits are reported in patients with attention deficit disorder, attention deficit hyperactivity disorder, eating disorders, substance use disorders, schizophrenia, depression, obsessive compulsive disorder, traumatic brain injury, Fragile X, Alzheimer’s disease, Parkinson’s disease and frontotemporal dementia.
      Many mental health disorders, as well as neurological disorders, are impacted by alterations, dysfunction, degeneration, and/or damage to the brain’s serotonergic system, which may explain, in part, common endophenotypes and comorbidities among neuropsychiatric and neurological diseases. Many therapeutic agents that modulate serotonergic function are commercially available, including serotonin reuptake inhibitors, selective serotonin reuptake inhibitors, antidepressants, monoamine oxidase inhibitors, and, while primarily developed for depressive disorders, many of these therapeutics are used across multiple medical indications including, but not limited to, depression in Alzheimer’s disease and other neurodegenerative disease, chronic pain, existential pain, bipolar disorder, obsessive compulsive disorder, anxiety disorders and smoking cessation. However, in many cases, the marketed drugs show limited benefit compared to placebo, can take six weeks to work and for some patients, and are associated with several side effects including trouble sleeping, drowsiness, fatigue, weakness, changes in blood pressure, memory problems, digestive problems, weight gain and sexual problems.
      The field of psychedelic neuroscience has witnessed a recent renaissance following decades of restricted research due to their legal status. Psychedelics are one of the oldest classes of psychopharmacological agents known to man and cannot be fully understood without reference to various fields of research, including anthropology, ethnopharmacology, psychiatry, psychology, sociology, and others. Psychedelics (serotonergic hallucinogens) are powerful psychoactive substances that alter perception and mood and affect numerous cognitive processes. They are generally considered physiologically safe and do not lead to dependence or addiction. Their origin predates written history, and they were employed by early cultures in many sociocultural and ritual contexts. After the virtually contemporaneous discovery of (5R,8R)-(+)-lysergic acid-N,N-diethylamide (LSD) and the identification of serotonin in the brain, early research focused intensively on the possibility that LSD and other psychedelics had a serotonergic basis for their action. Today there is a consensus that psychedelics are agonists or partial agonists at brain serotonin 5-hydroxytryptamine 2 A (5-HT2A) receptors, with particular importance on those expressed on apical dendrites of neocortical pyramidal cells in layer V, but also may bind with lower affinity to other receptors such as the sigma-1 receptor. Several useful rodent models have been developed over the years to help unravel the neurochemical correlates of serotonin 5-HT2A receptor activation in the brain, and a variety of imaging techniques have been employed to identify key brain areas that are directly affected by psychedelics.
      Psychedelics have both rapid onset and persisting effects long after their acute effects, which includes changes in mood and brain function. Long lasting effects may result from their unique receptor affinities, which affect neurotransmission via neuromodulatory systems that serve to modulate brain activity, i.e., neuroplasticity, and promote cell survival, are neuroprotective, and modulate brain neuroimmune systems. The mechanisms which lead to these long-term neuromodulatory changes are linked to epigenetic modifications, gene expression changes and modulation of pre- and post-synaptic receptor densities. These, previously under-researched, psychedelic drugs may potentially provide the next-generation of neurotherapeutics, where treatment resistant psychiatric and neurological diseases, e.g., depression, post-traumatic stress disorder, dementia and addiction, may become treatable with attenuated pharmacological risk profiles.
      Although there is a general perception that psychedelic drugs are dangerous, from a physiologic safety standpoint, they are one of the safest known classes of CNS drugs. They do not cause addiction, and no overdose deaths have occurred after ingestion of typical doses of classical psychotic agents, such as LSD, psilocybin, or mescaline (Scheme 1). Preliminary data show that psychedelic administration in humans results in a unique profile of effects and potential adverse reactions that need to be appropriately addressed to maximize safety. The primary safety concerns are largely psychologic, rather than physiologic, in nature. Somatic effects vary but are relatively insignificant, even at doses that elicit powerful psychologic effects. Psilocybin, when administered in a controlled setting, has frequently been reported to cause transient, delayed headache, with incidence, duration, and severity increased in a dose-related manner [Johnson et al., Drug Alcohol Depend, 2012, 123 (1-3):132-140]. It has been found that repeated administration of psychedelics leads to a very rapid development of tolerance known as tachyphylaxis, a phenomenon believed to be mediated, in part, by 5-HT2A receptors. In fact, several studies have shown that rapid tolerance to psychedelics correlates with downregulation of 5-HT2A receptors. For example, daily LSD administration selectively decreased 5-HT2 receptor density in the rat brain [Buckholtz et al., Eur. J. Pharmacol., 1990, 109:421-425. 1985; Buckholtz et al., Life Sci. 1985, 42:2439-2445].

Classic psychedelics and dissociative psychedelics are known to have rapid onset antidepressant and anti-addictive effects, unlike any currently available treatment. Randomized clinical control studies have confirmed antidepressant and anxiolytic effects of classic psychedelics in humans. Ketamine also has well established antidepressant and anti-addictive effects in humans mainly through its action as an NMDA antagonist. Ibogaine has demonstrated potent anti-addictive potential in pre-clinical studies and is in the early stages of clinical trials to determine efficacy in robust human studies [Barsuglia et al., Prog Brain Res, 2018, 242:121-158; Corkery, Prog Brain Res, 2018, 242:217-257].
      Psilocybin (4-phosphoryloxy-N,N-dimethyltrypatmine (iii, Scheme 1) has the chemical formula C 12H 17N 2O 4P. It is a tryptamine and is one of the major psychoactive constituents in mushrooms of the psilocybe species. It was first isolated from psilocybe mushrooms by Hofmann in 1957, and later synthesized by him in 1958 [Passie et al. Addict Biol., 2002, 7 (4):357-364], and was used in psychiatric and psychological research and in psychotherapy during the early to mid-1960 s up until its controlled drug scheduling in 1970 in the US, and up until the 1980 s in Germany [Passie 2005; Passie et al., Addict Biol., 2002, 7 (4):357-364]. Research into the effects of psilocybin resumed in the mid-1990 s, and it is currently the preferred compound for use in studies of the effects of serotonergic hallucinogens [Carter et al. J. Cogn. Neurosci., 2005 17 (10):1497-1508; Gouzoulis-Mayfrank et al. Neuropsychopharmacology 1999, 20 (6):565-581; Hasler et al, Psychopharmacology (Berl) 2004, 172 (2):145-156], likely because it has a shorter duration of action and suffers from less notoriety than LSD. Like other members of this class, psilocybin induces sometimes profound changes in perception, cognition and emotion, including emotional lability.
      In humans as well as other mammals, psilocybin is transformed into the active metabolite psilocin, or 4-hydroxy-N,N-dimethyltryptamine (iv, Scheme 1). It is likely that psilocin partially or wholly produces most of the subjective and physiological effects of psilocybin in humans and non-human animals. Recently, human psilocybin research confirms the 5HT2A activity of psilocybin and psilocin, and provides some support for indirect effects on dopamine through 5HT2A activity and possible activity at other serotonin receptors. In fact, the most consistent finding for involvement of other receptors in the actions of psychedelics is the 5-HT1 A receptor. That is particularly true for tryptamines and LSD, which generally have significant affinity and functional potency at this receptor. It is known that 5-HT1 A receptors are colocalized with 5-HT2A receptors on cortical pyramidal cells [Martin-Ruiz et al. J Neurosci. 2001, 21 (24):9856-986], where the two receptor types have opposing functional effects [Araneda et al. Neuroscience, 1991, 40 (2):399-412].
      Although the exact role of the 5-HT2A receptor, and other 5-HT2 receptor family members, is not well understood with respect to the amygdala, it is evident that the 5-HT2A receptor plays an important role in emotional responses and is an important target to be considered in the actions of 5-HT2A agonist psychedelics. In fact, a majority of known 5HT2A agonists produce hallucinogenic effects in humans, and rodents generalize from one 5HT2A agonist to others, as between psilocybin and LSD [Aghajanian et al., Eur J Pharmacol., 1999, 367 (2-3):197-206; Nichols at al., J Neurochem., 2004, 90 (3):576-584]. Psilocybin has a stronger affinity for the human 5HT2A receptor than for the rat receptor and it has a lower K(i) for both 5HT2A and 5HT2C receptors than LSD. Moreover, results from a series of drug-discrimination studies in rats found that 5HT2A antagonists, and not 5HT1 A antagonists, prevented rats from recognizing psilocybin [Winter et al., Pharmacol Biochem Behav., 2007, 87 (4):472-480]. Daily doses of LSD and psilocybin reduce 5HT2 receptor density in rat brain.
      Clinical studies in the 1960 s and 1970 s showed that psilocybin produces an altered state of consciousness with subjective symptoms such as “marked alterations in perception, mood, and thought, changes in experience of time, space, and self.” Psilocybin was used in experimental research for the understanding of etiopathogenesis of selective mental disorders and showed psychotherapeutic potential [Rucker et al., Psychopharmacol., 2016, 30 (12):1220-1229]. Psilocybin became increasingly popular as a hallucinogenic recreational drug and was eventually classed as a Schedule I controlled drug in 1970. Fear of psychedelic abuse led to a significant reduction in research being done in this area until the 1990 s when human research of psilocybin was revived when conditions for safe administration were established [Johnson et al., Psychopharmacol., 2008, 22 (6):603-620]. Today, psilocybin is one of the most widely used psychedelics in human studies due to its relative safety, moderately long active duration, and good absorption in subjects. There remains strong research and therapeutic potential for psilocybin as recent studies have shown varying degrees of success in neurotic disorders, alcoholism, depression in terminally ill cancer patients, obsessive compulsive disorder, addiction, anxiety, post-traumatic stress disorder and even cluster headaches. It could also be useful as a psychosis model for the development of new treatments for psychotic disorders. [Dubovyk and Monahan-Vaughn, ACS Chem. Neurosci., 2018, 9 (9):2241-2251].
      Recent developments in the field have occurred in clinical research, where several double-blind placebo-controlled phase 2 studies of psilocybin-assisted psychotherapy in patients with treatment resistant, major depressive disorder and cancer-related psychosocial distress have demonstrated unprecedented positive relief of anxiety and depression. Two recent small pilot studies of psilocybin assisted psychotherapy also have shown positive benefit in treating both alcohol and nicotine addiction. Recently, blood oxygen level-dependent functional magnetic resonance imaging and magnetoencephalography have been employed for in vivo brain imaging in humans after administration of a psychedelic, and results indicate that intravenously administered psilocybin and LSD produce decreases in oscillatory power in areas of the brain’s default mode network [Nichols D E. Pharmacol Rev., 2016 68 (2):264-355].
      Preliminary studies using positron emission tomography (PET) showed that psilocybin ingestion (15 or 20 mg orally) increased absolute metabolic rate of glucose in frontal, and to a lesser extent in other, cortical regions as well as in striatal and limbic subcortical structures in healthy participants, suggesting that some of the key behavioral effects of psilocybin involve the frontal cortex [Gouzoulis-Mayfrank et al., Neuropsychopharmacology, 1999, 20 (6):565-581; Vollenweider et al., Brain Res. Bull. 2001, 56 (5):495-507]. Although 5HT2A agonism is widely recognized as the primary action of classic psychedelic agents, psilocybin has lesser affinity for a wide range of other pre- and post-synaptic serotonin and dopamine receptors, as well as the serotonin reuptake transporter [Tyls et al., Eur. Neuropsychopharmacol. 2014, 24 (3):342-356]. Psilocybin activates 5HT1 A receptors, which may contribute to antidepressant/anti-anxiety effects.
      Depression and anxiety are two of the most common psychiatric disorders worldwide. Depression is a multifaceted condition characterized by episodes of mood disturbances alongside other symptoms such as anhedonia, psychomotor complaints, feelings of guilt, attentional deficits and suicidal tendencies, all of which can range in severity. According to the World Health Organization, the discovery of mainstream antidepressants has largely revolutionized the management of depression, yet up to 60% of patients remain inadequately treated. This is often due to the drugs’ delayed therapeutic effect (generally 6 weeks from treatment onset), side effects leading to non-compliance, or inherent non-responsiveness to them. Similarly, anxiety disorders are a collective of etiologically complex disorders characterized by intense psychosocial distress and other symptoms depending on the subtype. Anxiety associated with life-threatening disease is the only anxiety subtype that has been studied in terms of psychedelic-assisted therapy. This form of anxiety affects up to 40% of individuals diagnosed with life-threatening diseases like cancer. It manifests as apprehension regarding future danger or misfortune accompanied by feelings of dysphoria or somatic symptoms of tension, and often coexists with depression. It is associated with decreased quality of life, reduced treatment adherence, prolonged hospitalization, increased disability, and hopelessness, which overall contribute to decreased survival rates. Pharmacological and psychosocial interventions are commonly used to manage this type of anxiety, but their efficacy is mixed and limited such that they often fail to provide satisfactory emotional relief. Recent interest into the use of psychedelic-assisted therapy may represent a promising alternative for patients with depression and anxiety that are ineffectively managed by conventional methods.
      Generally, the psychedelic treatment model consists of administering the orally-active drug to induce a mystical experience lasting 4-9 h depending on the psychedelic [Halberstadt, Behav Brain Res., 2015, 277:99-120; Nichols, Pharmacol Rev., 2016, 68 (2): 264-355]. This enables participants to work through and integrate difficult feelings and situations, leading to enduring anti-depressant and anxiolytic effects. Classical psychedelics like psilocybin and LSD are being studied as potential candidates. In one study with classical psychedelics for the treatment of depression and anxiety associated with life-threatening disease, it was found that, in a supportive setting, psilocybin, and LSD consistently produced significant and sustained anti-depressant and anxiolytic effects.
      Psychedelic treatment is generally well-tolerated with no persisting adverse effects. Regarding their mechanisms of action, they mediate their main therapeutic effects biochemically via serotonin receptor agonism, and psychologically by generating meaningful psycho-spiritual experiences that contribute to mental flexibility. Given the limited success rates of current treatments for anxiety and mood disorders, and considering the high morbidity associated with these conditions, there is potential for psychedelics to provide symptom relief in patients inadequately managed by conventional methods.
      Further emerging clinical research and evidence suggest psychedelic-assisted therapy, also shows potential as an alternative treatment for refractory substance use disorders and mental health conditions, and thus may be an important tool in a crisis where existing approaches have yielded limited success. A recent systematic review of clinical trials published over the last 25 years summarizes some of the anti-depressive, anxiolytic, and anti-addictive effects of classic psychedelics. Among these, are encouraging findings from a meta-analysis of randomized controlled trials of LSD therapy and a recent pilot study of psilocybin-assisted therapy for treating alcohol use disorder [dos Santos et al., Ther Adv Psychopharmacol., 2016, 6 (3):193-213]. Similarly encouraging, are findings from a recent pilot study of psilocybin-assisted therapy for tobacco use disorder, demonstrating abstinence rates of 80% at six months follow-up and 67% at 12 months follow-up [Johnson et al., J Drug Alcohol Abuse, 2017, 43 (1):55-60; Johnson et al., Psychopharmacol. 2014, 28 (11):983-992], such rates are considerably higher than any documented in the tobacco cessation literature. Notably, mystical-type experiences generated from the psilocybin sessions were significantly correlated with positive treatment outcomes. These results coincide with bourgeoning evidence from recent clinical trials lending support to the effectiveness of psilocybin-assisted therapy for treatment-resistant depression and end-of-life anxiety [Carhart-Harris et al. Neuropsychopharmacology, 2017, 42 (11):2105-2113]. Research on the potential benefits of psychedelic-assisted therapy for opioid use disorder (OUD) is beginning to emerge, and accumulating evidence supports a need to advance this line of investigation. Available evidence from earlier randomized clinical trials suggests a promising role for treating OUD: higher rates of abstinence were observed among participants receiving high dose LSD and ketamine-assisted therapies for heroin addiction compared to controls at long-term follow-ups. Recently, a large United States population study among 44,000 individuals found that psychedelic use was associated with 40% reduced risk of opioid abuse and 27% reduced risk of opioid dependence in the following year, as defined by DSM-IV criteria [Pisano et al., J Psychopharmacol., 2017, 31 (5):606-613]. Similarly, a protective moderating effect of psychedelic use was found on the relationship between prescription opioid use and suicide risk among marginalized women [Argento et al., J Psychopharmacol., 2018, 32 (12):1385-1391]. Despite the promise of these preliminary findings with classical psychedelic agents, further research is warranted to determine what it may contribute to the opioid crisis response given their potential toxicity. Meanwhile, growing evidence on the safety and efficacy of psilocybin for the treatment of mental and substance use disorders should help to motivate further clinical investigation into its use as a novel intervention for OUD.
      Regular doses of psychedelics also ameliorate sleep disturbances, which are highly prevalent in depressive patients with more than 80% of them having complaints of poor sleep quality. The sleep symptoms are often unresolved by first-line treatment and are associated with a greater risk of relapse and recurrence. Interestingly, sleep problems often appear before other depression symptoms, and subjective sleep quality worsens before the onset of an episode in recurrent depression. Brain areas showing increased functional connectivity with poor sleep scores and higher depressive symptomatology scores included prefrontal and limbic areas, areas involved in the processing of emotions. Sleep disruption in healthy participants has demonstrated that sleep is indeed involved in mood, emotion evaluation processes and brain reactivity to emotional stimuli. An increase in negative mood and a mood-independent mislabeling of neutral stimuli as negative was for example shown by one study while another demonstrated an amplified reactivity in limbic brain regions in response to both negative and positive stimuli. Two other studies assessing electroencephalographic (EEG) brain activity during sleep showed that psychedelics, such as LSD, positively affect sleep patterns. Moreover, it has been shown that partial or a full night of sleep deprivation can alleviate symptoms of depression suggested by resetting circadian rhythms via modification of clock gene expression. It further was suggested that a single dose of a psychedelic causes a reset of the biological clock underlying sleep/wake cycles and thereby enhances cognitive-emotional processes in depressed people but also improving feelings of well-being and enhances mood in healthy individuals [Kuypers, Medical Hypotheses, 2019, 125:21-24].
      In a systematic meta-analysis of clinical trials from 1960-2018 researching the therapeutic use of psychedelic treatment in patients with serious or terminal illnesses and related psychiatric illness, it was found that psychedelic therapy (mostly with LSD) may improve cancer-related depression, anxiety, and fear of death. Four randomized controlled clinical trials were published between 2011 and 2016, mostly with psilocybin treatment, that demonstrated psychedelic-assisted treatment can produce rapid, robust, and sustained improvements in cancer-related psychological and existential distress. [Ross S, Int Rev Psychiatry, 2018, 30 (4):317-330]. Thus, the use of psychedelics in the fields of oncology and palliative care is intriguing for several reasons. First, many patients facing cancer or other life-threatening illnesses experience significant existential distress related to loss of meaning or purpose in life, which can be associated with hopelessness, demoralization, powerlessness, perceived burdensomeness, and a desire for hastened death. Those features are also often at the core of clinically significant anxiety and depression, and they can substantially diminish quality of life in this patient population. The alleviation of those forms of suffering should be among the central aims of palliative care. Accordingly, several manualized psychotherapies for cancer-related existential distress have been developed in recent years, with an emphasis on dignity and meaning-making. However, there are currently no pharmacologic interventions for existential distress per se, and available pharmacologic treatments for depressive symptoms in patients with cancer have not demonstrated superiority over placebo. There remains a need for additional effective treatments for those conditions [Rosenbaum et al., Curr. Oncol., 2019, 26 (4): 225-226].
      Recently, there has been growing interest in a new dosing paradigm for psychedelics such as psilocybin and LSD referred to colloquially as microdosing. Under this paradigm, sub-perceptive doses of the serotonergic hallucinogens, approximately 10% or less of the full dose, are taken on a more consistent basis of once each day, every other day, or every three days, and so on. Not only is this dosing paradigm more consistent with current standards in pharmacological care, but may be particularly beneficial for certain conditions, such as Alzheimer’s disease and other neurodegenerative diseases, attention deficit disorder, attention deficit hyperactivity disorder, and for certain patient populations such as elderly, juvenile and patients that are fearful of or opposed to psychedelic assisted therapy. Moreover, this approach may be particularly well suited for managing cognitive deficits and preventing neurodegeneration. For example, subpopulations of low attentive and low motivated rats demonstrate improved performance on 5 choice serial reaction time and progressive ratio tasks, respectively, following doses of psilocybin below the threshold for eliciting the classical wet dog shake behavioral response associated with hallucinogenic doses (Blumstock et al., WO 2020/157569 A1). Similarly, treatment of patients with hallucinogenic doses of 5HT2A agonists is associated with increased BDNF and activation of the mTOR pathway, which are thought to promote neuroplasticity and are hypothesized to serve as molecular targets for the treatment of dementias and other neurodegenerative disorders (Ly et al. Cell Rep., 2018, 23 (11):3170-3182). Additionally, several groups have demonstrated that low, non-hallucinogenic and non-psychomimetic, doses of 5HT2A agonists also show similar neuroprotective and increased neuroplasticity effects (neuroplastogens) and reduced neuroinflammation, which could be beneficial in both neurodegenerative and neurodevelopmental diseases and chronic disorders (Manfredi et al., WO 2020/181194, Flanagan et al., Int. Rev. Psychiatry, 2018, 13:1-13; Nichols et al., 2016, Psychedelics as medicines; an emerging new paradigm). This repeated, lower, dose paradigm may extend the utility of these compounds to additional indications and may prove useful for wellness applications.
      Psychosis is often referred to as an abnormal state of mind that is characterized by hallucinatory experiences, delusional thinking, and disordered thoughts. Moreover, this state is accompanied by impairments in social cognition, inappropriate emotional expressions, and bizarre behavior. Most often, psychosis develops as part of a psychiatric disorder, of which, it represents an integral part of schizophrenia. It corresponds to the most florid phase of the illness. The very first manifestation of psychosis in a patient is referred to as first-episode psychosis. It reflects a critical transitional stage toward the chronic establishment of the disease, that is presumably mediated by progressive structural and functional abnormalities seen in diagnosed patients. [ACS Chem. Neurosci. 2018, 9, 2241-2251]. Anecdotal evidence suggests that low, non-hallucinogenic, doses (microdosing) of psychedelics that are administered regularly can reduce symptoms of schizophrenia an
