Transforming mental health care with psilocybin treatments.

APEX is a patient-driven pharmaceutical company. 

Our mission is to develop and commercialize clinically evaluated psilocybin-derived treatments to tackle the most critical unmet need in depression, anxiety, and PTSD among Veterans and the general public. 

Our vision is to work with regulators and advocacy groups to expedite our clinical programs and data capture to facilitate broader global access.

Addressing a sub-optimal standard of care 

Despite being the current standard of care treatment for depression, anxiety and PTSD, studies estimate antidepressants improve symptoms in around half of patients, a coin toss at best.

The APEX Strategy

Develop and commercialize pharmaceutical assets that address significant unmet need across many established patient segments through phased clinical trial pipelines and a robust early access program (EAP).

Commercial strategy

APEX is currently evaluating two unique drug assets seeking Health Canada Approval that will be optimized for all relevant disease states: 

  • Microdose drug candidate (APEX-52) optimized for take-home dosing targeting mild to moderate disease severity 
  • Macrodose drug candidate (APEX-90) positioned for in-clinic dosing with assisted psychotherapy targeting more severe disease

Regulatory Strategy

Following Canadian phase 2b study completion with demonstrated outcomes, APEX will pursue a regulatory pathway towards commercial approval in the US, Europe and Australia.

Patient Focus

As a Veteran-founded organization, APEX is seeking indications for the general population and will prioritize Veteran patient communities that represent very high unmet need in clinical trial recruitment and the EAP. APEX will leverage access to a network of thousands of Veteran patients and strong relationships with Veteran-focused practitioners to expedite recruitment to the most qualified patient candidates.
