“The clinical progress we have made over the past few months is truly remarkable, exemplified by our recently released positive Phase 2 interim data for CYB003 in major depressive disorder (“MDD”), which demonstrated rapid and significant improvement in depression symptoms three weeks after a single dose,” said Doug Drysdale, Chief Executive Officer of Cybin. “In coming months, we look forward to presenting the complete Phase 2 topline data for CYB003 in MDD, as well as Phase 1 data readouts for our proprietary novel deuterated N,N-dimethyltryptamine (“DMT”) compounds, CYB004 and SPL028.”

Upcoming clinical milestones:

CYB003 - Deuterated Psilocybin Analog Program

• Complete Phase 2 topline safety and efficacy data readout for CYB003 in MDD, including 6-week data and results on the incremental benefit of a second dose expected in Q4 2023
• Submission of topline data to U.S. Food and Drug Administration (“FDA”) following readout, for an end of Phase 2 meeting in early 2024
• Additional Phase 2 data assessing durability of effect for CYB003 at 12 weeks expected in Q1 2024
• Progression to an international, multisite Phase 3 trial in early 2024 to further evaluate the safety and efficacy of CYB003 capsules in a larger MDD patient population, with recruiting expected to begin by end of Q1 2024

Deuterated DMT Program

• Phase 1 dosing, pharmacokinetic (“PK”) and pharmacodynamic (“PD”), and safety data for CYB004 and SPL028 expected in Q4 2023
