"During the past 12 months, we have continued to focus on building out the strong foundation that underpins the clinical and regulatory milestones we anticipate in the coming year," said Doug Drysdale, Chief Executive Officer of Cybin. "Heartened by U.S. Food and Drug Administration Commissioner Dr. Martin Makary's recent comments in support of prioritizing this innovative scientific work, as well as the burgeoning government and media attention the field is receiving, we remain steadfastly committed to advancing our two lead programs, CYB003 and CYB004, toward potential approval and commercialization."

"Developing novel therapies to address the unmet need in mental health care requires dedication, scientific rigor, and the integration of expertise across domains. To help us accelerate our clinical goals, we have entered into several strategic collaborations, including with Osmind and Thermo Fisher Scientific, and have formed strategic partnership agreements among our clinical trial sites. In this way, we leverage the competencies, resources, and infrastructures of these key stakeholders with a goal of expediting the development pathway. Cybin's lead clinical programs – CYB003, our Phase 3 pivotal program for the adjunctive treatment of major depressive disorder, and CYB004, our Phase 2 program in generalized anxiety disorder – continue to advance, and we look forward to sharing future updates."
