Cybin Announces Positive CYB004 Data Demonstrating Significant Advantages Over Intravenous and Inhaled DMT

TORONTO–(BUSINESS WIRE)– Cybin Inc. (NEO:CYBN) (NYSE American:CYBN) (Cybin or the Company), a biopharmaceutical company focused on progressing “Psychedelics to TherapeuticsTM”, today announced positive preclinical data from a pharmacokinetic study evaluating its proprietary deuterated dimethyltryptamine (DMT) molecule, CYB004, delivered via inhalation. Specifically, inhaled CYB004 demonstrated significant advantages over both IV DMT and inhaled DMT, including longer duration of action, and improved bioavailability. The study also demonstrated that inhaled CYB004 showed a similar onset of effect and dose profile to IV DMT. These data may support the potential for inhalation as a viable and well-controlled delivery system of therapeutic psychedelics. Cybin is currently developing CYB004 for the treatment of anxiety disorders.

“In many studies, DMT has shown to be a promising and effective psychedelic for the treatment of mental health issues. However, known side effects like disorientation and anxiety and its mode of administration have historically hindered its use and availability. CYB004 via inhalation may solve these challenges and finally support a clinical path forward for this important therapeutic. As part of Cybin’s overall mission to create safe and effective psychedelic-based therapeutics, inhaled CYB004 is being developed to potentially overcome the limitations of IV DMT and become an important treatment option for anxiety disorders for patients and physicians,” said Doug Drysdale, Chief Executive Officer of Cybin.

Based on preclinical results, inhaled CYB004 demonstrated:

• Approximately 2000% improved bioavailability compared with orally administered DMT, which is known to have limited to no oral bioavailability
• Approximately 41% improved bioavailability compared with inhaled DMT
• Approximately 300% longer duration of effect when compared with IV DMT, indicating potential to extend therapeutic window
• Rapid onset of effect and similar low variability equivalent to IV DMT
