NEW YORK and BERLIN, January 4, 2024 -- atai Life Sciences (NASDAQ: ATAI) (“atai” or “Company”), a clinical-stage biopharmaceutical company aiming to transform the treatment of mental health disorders, today announced a strategic investment in Beckley Psytech Limited (“Beckley Psytech”), a private clinical-stage biotechnology company dedicated to transforming short-duration psychedelics into effective and rapid-acting medicines for neuropsychiatric conditions.

This strategic investment and collaboration aims to accelerate the development of Beckley Psytech’s two clinical-stage, patent-protected, short-duration psychedelic candidates, BPL-003 and ELE-101, by adding them to atai’s mental health innovation platform. BPL-003 is a novel, short-duration, intranasal formulation of 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT also known as Mebufotenin), and ELE-101 is a novel intravenous formulation of psilocin, the primary moiety of psilocybin.

“This transaction underscores our conviction in the potential of psychedelics as groundbreaking treatments for people living with mental health disorders. Short-duration psychedelics have the potential to offer similar clinical benefit to longer-acting psychedelics, in a more efficient and scalable way, which could lead to increased patient access. By including BPL-003 and ELE-101 in the atai platform, we are building the largest portfolio of psychedelic compounds with prior clinical evidence,” said atai Founder and Chairman, Christian Angermayer.

Beckley Psytech’s CEO, Cosmo Feilding Mellen said: “Beckley Psytech and atai Life Sciences share a vision for the future of mental health treatment, and we are excited to join forces on the journey to develop effective, accessible, rapid-acting psychedelic medicines for people in need. Alongside the financial investment, we are optimistic about the numerous possible synergies of this collaboration, especially in developing digital tools to optimize patient support and planning for future commercialization. We look forward to exploring these in the coming months.”

BPL-003 is currently in development for two indications: Treatment Resistant Depression (TRD) and Alcohol Use Disorder (AUD), with three clinical trials underway. The first trial is a global, multi-site, double-blind, randomized Phase 2b study in people living with TRD, evaluating the effects of a medium and high dose of BPL-003 against an active placebo comparator in 225 patients with moderate-to-severe TRD. Medium and high dosages were found to reliably induce profound psychedelic experiences in a completed Phase 1 trial, with a rapid onset of psychedelic effects within minutes and the resolution of all perceptual effects within 60-90 minutes. In addition to the Phase 2b study in TRD that is anticipated to read out in the second half of 2024, BPL-003 is also being investigated in two small Phase 2a open-label studies in TRD and AUD, with data expected in the first half of 2024 and mid 2024 respectively.

Beckley Psytech’s second candidate ELE-101 is being developed for the treatment of Major Depressive Disorder (MDD). This compound has the potential to offer the therapeutic benefits of psilocybin, which has demonstrated significant antidepressant effects in multiple clinical studies, in a more consistent, controllable, and shorter treatment paradigm of less than 2 hours. Initial results from the current ELE-01 Phase 1/2a study are anticipated in the first half of 2024.

atai Co-founder and Chief Executive Officer, Florian Brand added:“When it comes to mental health, there is no one-size-fits-all solution, and the diverse pharmacology of our drug candidates acknowledges the heterogeneity of neuropsychiatric patient populations. Looking ahead to the next 12 months,adding to our already strong pipeline of potential catalysts, we anticipate this investment will lead to several additional meaningful clinical readouts, including topline results from the BPL-003 Phase 2b study, expected in the second half of 2024.”

Under the terms of the investment Beckley Psytech will remain an independent, privately-owned company and atai will own 35.5% of Beckley Psytech. This is based on a $50m total investment, with a $40m direct investment into the company to fund ongoing research programs, and an additional $10m in secondary share purchases from existing shareholders. Upon closing, atai will receive 1:1 warrant coverage at a 30% premium on the primary issuances. atai will also have the right to appoint and hold 3 of the 9 seats in Beckley Psytech’s Board of Directors, and will hold a time-limited right of first refusal on a future sale of the company, asset sales or other transfer of commercial rights, as well as an indefinite right of first negotiation for BPL-003 and ELE-101.
