Reunion Neuroscience Inc. (NASDAQ: REUN | TSX: REUN), a biopharmaceutical company committed to developing innovative and patented therapeutic solutions for underserved mental health conditions, today reported its business update and fiscal second quarter ended September 30, 2022 results.

“Reunion has hit the ground running as an independent company, advancing our mission of developing innovative and patent protected therapeutic solutions for mental health conditions for the hundreds of millions of people with unmet mental health needs. We are well positioned to round out the year in preparation for what promises to be an exciting 2023. I am thrilled to announce that we have dosed all subjects in the first four cohorts of our Phase 1 study with a planned readout set for Q1 2023 and have strengthened our leadership team, appointing seasoned industry professionals in the roles of Chief Financial Officer, Vice President of Medical Affairs, and General Counsel to support our next stage of growth.”

Greg Mayes, President & Chief Executive Officer of Reunion

Key Highlights and Recent Developments

RE104
Reunion is developing its lead clinical-stage drug candidate, RE104, a patent protected novel serotonergic psychedelic designed to deliver quick onset, limited duration psychoactivity and durable antidepressant activity. RE104, the only novel prodrug of 4-OH-DIPT, aims to reduce the treatment burden for patients and payers and provide a safe and effective new therapeutic option for the large population of underserved patients suffering from postpartum depression, and potentially other mental health indications.

Reunion announced the first successful dosings in the RE104 Phase 1 Clinical Study in July 2022, and subsequent to quarter end, completed the dosing of the four prespecified cohorts, representing 32 subjects, for its planned interim analysis to be released in the first calendar quarter of 2023. The study aims to determine the safety, tolerability, pharmacokinetics and pharmacodynamic effects of RE104 over a range of dosage levels. Results of subjective measurements including intensity, duration and feelings produced by the period of acute psychoactivity after administration of RE104 will be used to select an appropriate recommended phase 2 dose (RP2D). Per the Phase 1 protocol, up to two additional dosing cohorts may be evaluated based on pharmacokinetics, pharmacodynamics and safety.

Data generated from the interim analysis will be used to support its planned pre-IND regulatory interactions with the United States Food and Drug Administration (US FDA) in early 2023 where the Company will also present plans for opening an Investigational New Drug (IND) application later in the year for the development of RE104 as a treatment for postpartum depression.

Dr. Nathan Bryson, Chief Scientific Officer, Reunion, commented, “The rapid enrollment of our RE104 Phase 1 clinical study clearly demonstrates significant progress toward our goal of advancing a differentiated molecule which could offer a convenient and effective therapeutic option for patients who suffer from depression and other mental health disorders. We look forward to sharing data from the Phase 1 study in the first quarter of 2023 and laying the groundwork in preparation for our RE104 Phase 2 program.”

RE200 Series
Reunion is also developing the RE200 series. These novel molecules are structurally similar to classical psychedelics, but have selective potency at the target serotonin 2A receptor (5HT2A) and are devoid of 5HT2B receptor agonism. During the second quarter, Reunion progressed in its understanding of some of the structural features that define this class of new chemical entity (NCE) molecules, initiated preclinical work to identify potential drug candidates in the RE200 series and strengthened its patent portfolio. The Company plans to nominate its first lead clinical candidate from the RE200 series in 2023.

Corporate Updates

In September, the Company appointed Greg Mayes as President and Chief Executive Officer, with Joseph del Moral stepping into the role of Chairman. Mr. Mayes’ initial focus is on the successful completion of the Company’s Phase 1 clinical trial with RE104 and the planned launch of its Phase 2 study in postpartum depression. Mr. Mayes will also progress Reunion’s preclinical RE200 research focused on the discovery of selective and specific serotonergic psychedelics.

Post quarter end, Reunion announced the appointment of Edward Smith as the Company’s Chief Financial Officer, Dr. Aviva Asnis-Alibozek as Vice President, Medical Affairs and Curtis Weber as General Counsel.

Mr. Mayes continued, “Reunion’s strong composition of matter intellectual property significantly differentiates us from other psychedelic therapeutic companies. Making Reunion even more exciting is the Company’s development program, which targets a niche initial indication with high unmet therapeutic need – PPD. We firmly believe that our IP is what distinguishes us, our choice of molecule differentiates us, and our team is what will separate us from the growing number of companies in this space. These factors will continue to generate further interest in Reunion as we seek to build partnerships and expand our clinical pipeline toward the future.”

Corporate Structure and Basis of Presentation

On August 11, 2022, the Company completed its previously announced spinout of its clinics and botanical research operations (Clinic Operations) to Field Trip Health & Wellness with the resulting drug discovery and development business renamed Reunion Neuroscience Inc., which is listed on the NASDAQ Stock Market and Toronto Stock Exchange under the ticker symbol “REUN”.

Reunion accounted for the Clinic Operations as discontinued operations whose assets and liabilities are classified and presented separately as current items held for transfer in the statement of financial position and are measured at their carrying amount. Clinic Operations are excluded from the results of continuing operations and are presented as a single amount as a net loss from discontinued Clinic Operations in the unaudited interim condensed consolidated statements of loss.
