Cybin: Clinilabs Granted Schedule I DEA License for CYB003 Phase 1/2a First-In-Human Clinical Trial – Form 6-K

Cybin Inc. (NEO: CYBN) (NYSE American: CYBN), a biopharmaceutical company focused on progressing “Psychedelics to TherapeuticsTM”, and its partner Clinilabs Drug Development Corporation, a global, full-service contract research organization with deep expertise in central nervous system drug development, today announced that the U.S. Drug Enforcement Agency (“DEA”) has granted a Schedule I license to support the first-in-human Phase 1/2a clinical trial of CYB003, a proprietary deuterated psilocybin analog that is being developed for the treatment of major depressive disorder (“MDD”).

The DEA license is a federal requirement for any investigators who intend to study, produce, analyze, or otherwise work with Schedule I controlled substances.

The Phase 1/2a trial is a randomized, double-blind, placebo-controlled study evaluating people with moderate to severe MDD. Participants will receive two administrations (placebo/active and active/active) and a response/remission will be assessed at Week 3 (after first dose) and at Week 6 (after second dose). Importantly, participants in the trial that are currently being treated with antidepressants will be allowed to remain on their antidepressant medication.

Using the Montgomery-Asberg Depression Rating Scale, the trial will assess rapid onset of antidepressant effect on the day of dosing. The study will also evaluate the incremental benefit of a second dose of CYB003 when administered at Week 3 and will provide important PK and safety data to determine a clinical path forward. An optional period of assessment will help

determine the durability of treatment effect out to 12 weeks. The detailed Phase 1/2a study protocol is available at clinicaltrials.gov under the Identifier number: NCT05385783.

This research study is recruiting individuals between the ages of 21 and 55 who have been diagnosed with MDD and who are currently taking an antidepressant medication that is not working to their satisfaction. Participation includes 11 outpatient visits and two 2-day inpatient stays. Participants who are located within reasonable travel distance to the Clinilabs Eatontown, New Jersey clinical research unit, may pre-screen for study entry at www.depressionpsychedelicstudy.com or by telephone at (212) 994-4567.

CYB003 is a deuterated analog of psilocybin, which is part of a family of molecules called indolamines that include more common neurotransmitters, such as serotonin. Psilocybin is dephosphorylated to form its metabolite psilocin, which can cross the blood-brain-barrier. Given its structural similarity to serotonin, psilocin can easily activate the serotonin 5-HT2A receptor.

CYB003 is designed to potentially address the challenges and limitations of oral psilocybin. Based on preclinical data, CYB003 achieved less variability in plasma levels, faster onset of action, and shorter duration of effect. We believe CYB003 has the potential to reduce time and resource burden on patients, providers, and payers, and possibly improve scalability and accessibility of treatment.
