We are a mental health care company dedicated to accelerating patient access to evidence-based innovation in mental health. We are motivated by the need to find better ways to help and empower people suffering with mental health challenges who are not helped by existing therapies, and are pioneering the development of a new model of psilocybin therapy, in which psilocybin is administered in conjunction with psychological support. Our initial focus is on treatment-resistant depression, or TRD, a subset of major depressive disorder, or MDD, comprising patients who are inadequately served by the current treatment paradigm. Early signals from academic studies, using formulations of psilocybin not developed by us, have shown that psilocybin therapy may have the potential to improve outcomes for patients suffering with TRD, with rapid reductions in depression symptoms and effects lasting up to six months, after administration of a single high dose. We have developed a proprietary, high-purity polymorphic crystalline formulation of psilocybin, COMP360. In 2019, we completed a Phase I clinical trial administering COMP360, along with psychological support, to 89 healthy volunteers, the largest randomized, controlled trial with psilocybin therapy to date. In this trial, we observed that COMP360 was generally well-tolerated and supported continued progression of Phase IIb studies. We are currently evaluating COMP360 in conjunction with psychological support in a Phase IIb trial and we plan to report data from this trial in late 2021. We believe that a single dose of our COMP360 monotherapy with psychological support from specially trained therapists could offer a new approach to depression care.

Globally, more than 320 million people suffer with MDD. The economic burden of MDD in the United States, accounting for comorbid physical and psychiatric conditions, is estimated to be over $200 billion per year. TRD, a condition affecting the approximately 100 million patients worldwide who are not helped after two or more existing depression treatments, has even greater economic and societal cost than non-TRD MDD. TRD patients are often unable to perform daily tasks, are more likely to receive disability or welfare benefits and more frequently have co-occurring conditions compared with non-TRD MDD patients. Direct medical costs for TRD patients are estimated to be two to three times higher than for non-TRD MDD patients, caused by, among other factors, increased rates of hospitalization and longer average hospital stays. In addition, there is approximately a seven-fold increase in suicide rate for TRD patients compared with non-TRD MDD patients.

Patients suffering with depression are treated through a variety of approaches, each of which can have significant shortcomings in certain subsets of patients. Most pharmacotherapies for depression employ the same mechanism of action, targeting the modulation of the brain’s neurotransmitter monoamine levels, and have exhibited limited efficacy in a significant portion of patients and can result in high relapse rates. There are only two pharmacotherapies specifically approved for TRD in the U.S.: esketamine, and a combination of olanzapine (an atypical antipsychotic) and fluoxetine (a selective serotonergic reuptake inhibitor). Esketamine was recently approved by the U.S. Food and Drug Administration, or FDA. Mixed efficacy and limited durability were observed in clinical trials as well as potential side effects, including dissociation and cognitive impairment. The olanzapine-fluoxetine combination has also shown mixed efficacy and can commonly lead to side effects such as dizziness, drowsiness and weight gain. In addition to pharmacotherapies, various forms of somatic intervention are also used, although these treatments tend to be invasive and/or onerous, and there are limited data supporting their long-term benefit. Psychotherapy is another common treatment approach, but it requires a significant time commitment and is subject to large variability in availability and administration. Despite the range of treatments and therapies available for depression, patients suffering with TRD continue to be underserved, prolonging a significant health, social and economic burden. We believe patients suffering with TRD need a paradigm-shifting treatment that can deliver rapid and sustained relief of their depression.
