Lead Clinical Development Programs

Deuterated Psilocybin Analog Program

CYB003 is a proprietary molecule derived from psilocybin, which is part of a family of molecules called indolamines that includes more common neurotransmitters like serotonin. Psilocybin is dephosphorylated to form its metabolite, psilocin, which can cross the blood-brain-barrier. Given its structural similarity to serotonin, psilocybin can easily activate the serotonin 5-HT2A receptor. CYB003 is a deuterated psilocybin analog being developed to potentially provide a safer and more effective outcome for patients and providers.

CYB003 is being evaluated as a potential treatment for Major Depressive Disorder (MDD).

Current status: Positive Phase 2 topline data in MDD released

Upcoming milestones:

Additional Phase 2 data assessing long-term efficacy for CYB003 at 3 months expected in Q1 2024

FDA end of Phase 2 meeting in early 2024

Initiate Phase 3 trial of CYB003 in MDD in Q2 2024

N,N-Dimethyltryptamine (DMT) Program (CYB004, SPL028, SPL026)

Cybin’s portfolio includes the most advanced and extensive DMT dataset in the psychedelic drug development sector. The Company’s DMT portfolio is comprised of deuterated DMT (“dDMT”) molecules CYB004 and SPL028, which have the potential for less invasive, more convenient and patient-friendly dosing methods, in addition to SPL026, intravenous (“IV”) DMT.

CYB004, Cybin’s proprietary dDMT molecule, is being evaluated as a potential treatment for Generalized Anxiety Disorder. CYB004 is protected by a U.S. composition of matter patent expected to provide coverage until at least 2041.

The Company has completed multiple clinical trials providing proof-of-concept for its DMT/dDMT assets, including:

Phase 2a safety and efficacy for SPL026 (IV DMT) in 34 participants with MDD, demonstrating a clinically relevant and statistically significant reduction in depression symptoms at two weeks after dosing (-7.4 point difference in MADRS between SPL026 and placebo). Durable antidepressant response and remission rates were observed at 6 months. Among participants who had achieved remission within three months with SPL026, 64% sustained remission to 6 months.
Phase 1 studies evaluating intramuscular (“IM”) SPL026 and SPL028 supporting IM administration for patient-friendly dosing. The completed Phase 1 study of IV/IM SPL028 in healthy volunteers showed that SPL028 is safe and well-tolerated, and demonstrated that IM dosing of SPL028 produced robust psychedelic effects lasting a short duration in the majority of subjects
Phase 1b study evaluating the safety and efficacy of SPL026 in conjunction with SSRIs in 17 participants with MDD, demonstrating no relevant drug-drug interactions, a favorable safety profile and enhanced efficacy when SPL026 was administered with SSRIs, and a 92% remission rate at 4 weeks in the DMT + SSRI combination cohort (n=12). Phase 1 topline data for IV CYB004 demonstrated robust and rapid-onset psychedelic effects at lower doses compared to native DMT, suggesting potential as a short-acting, scalable treatment

Exploratory analysis of data from these studies also shows significant improvements in symptoms of anxiety, as measured using the State Trait Anxiety Inventory – Trait version (STAI-T), with a 22 point improvement from baseline at the 2 week endpoint, in the DMT+SSRI combination group.

Current status: Phase 1 CYB004 and Phase 1 IM/IV SPL028 studies complete with a Phase 2 study in Generalized Anxiety Disorder (“GAD”) in the United States expected to begin in Q1 2024.
