Compass Pathways Announces First Quarter 2024 Financial Results and Business Highlights
Compass Pathways plc (Nasdaq: CMPS) (“Compass”), a biotechnology company dedicated to accelerating patient access to evidence-based innovation in mental health, today reported its financial results for the first quarter 2024 and provided an update on recent business progress.

Kabir Nath, Chief Executive Officer, said, “We were pleased to see the positive results from the phase 2 PTSD study, a condition with significant unmet need and limited therapeutic options for the people who live with it. PTSD is a logical extension for COMP360 psilocybin treatment as there is significant overlap in patients living with treatment-resistant depression and PTSD. These strong data enable us to explore the optimal path forward to advance clinical development in PTSD alongside our phase 3 pivotal program in TRD, which is on track for initial data this year. We also continue to prepare for commercialization of COMP360 in TRD if approved by the FDA and have established collaborations with important mental health providers in the US to investigate models for the delivery of COMP360 psilocybin treatment at scale in diverse care settings.”

Business highlights

COMP360 psilocybin treatment in treatment-resistant depression (TRD):

  • Phase 3 program ongoing, composed of two pivotal trials with an integrated, long-term outcomes component
    • Pivotal trial 1 (COMP005): single dose monotherapy, n=255, top-line data expected Q4 2024
    • Pivotal trial 2 (COMP006): fixed repeat dose monotherapy, n=568, top-line data expected mid-2025
    • Long-term follow up in each trial will generate data on duration of response and potential effect of retreatment
    • Additional research collaborations with Reliant Medical Group (a part of Optum Care), Mindful Health Solutions, and Journey Clinical launched to explore and develop multiple commercial delivery templates for COMP360 psilocybin treatment, if approved

COMP360 psilocybin treatment in post-traumatic stress disorder (PTSD):

  • 22 patient, multi-center open label study, single administration of 25mg COMP360 with psychological support
  • COMP360 was well tolerated with no treatment emergent serious adverse events reported
  • Early and durable change from baseline in CAPS-5 observed at week 4 (29.9 points) and week 12 (29.5 points)
  • Improvement over time in Sheehan Disability Scale (SDS) measure of functional impairment over 12 weeks from a mean total score of 22.7 at baseline to a 11.7 point reduction at week 4 and a 14.4 point reduction at week 12
  • High and sustained rates of response and remission relative to baseline, with early onset of symptom improvement, accompanied by increasing functional improvement at 4 and 12 weeks
  • Based on results, Compass is exploring the optimal path forward for PTSD

Management update

  • Michael Gold, MD, will join Compass as Chief Research and Development Officer, effective May 20, 2024. Previously Chief Medical Officer at Neumora Therapeutics, Gold brings more than 25 years of experience across all aspects of drug development in neuroscience, with extensive therapeutic experience in neurological disorders and psychiatric disorders, including depression. Gold will work with Guy Goodwin, Compass's Chief Medical Officer, to continue developing COMP360 in TRD and other indications, and to explore and advance other potential pipeline opportunities.
  • Trevor Mill, Chief Development Officer, will leave Compass to pursue other opportunities. Trevor led the development of the COMP360 program in TRD, launched programs in PTSD and anorexia nervosa, and was instrumental in guiding the exploration of additional early pipeline opportunities.

Financial highlights

  • Net loss for the three months ended March 31, 2024, was $35.2 million, or $0.55 loss per share (including non-cash share-based compensation expense of $5.1 million), compared with $24.2 million, or $0.57 loss per share, during the same period in 2023 (including non-cash-share-based compensation expense of $4.1 million). 
  • Research and development expenses were $24.9 million for the three months ended March 31, 2024, compared with $19.0 million during the same period in 2023. The increase was primarily attributable to development expenses, associated with advancing our COMP360 phase 3 clinical trials, and increased personnel expenses due to increased R&D headcount. 
  • General and administrative expenses were $13.7 million for the three months ended March 31, 2024, compared with $12.8 million during the same period in 2023. The increase was primarily attributable to increases in non-cash share-based compensation, and legal and professional fees.
  • Cash and cash equivalents were $262.9 million as of March 31, 2024, compared with $220.2 million as of December 31, 2023. 
  • Long term debt was $29.1 million as of March 31, 2024, compared with $28.8 million as of December 31, 2023. 
  • Additional $63.5 million net cash raised in first quarter 2024 through ATM facility and proceeds from exercise of warrants

Financial Guidance

Second quarter 2024 net cash used in operating activities is expected to be in the range of $32 million to $38 million. The full-year 2024 net cash used in operating activities is expected to be in the range of $110 million to $130 million and assumes the 2023 R&D tax credit is received in 4Q 2024. The cash position at March 31, 2024, is expected to be sufficient to fund operating expenses and capital expenditure requirements into 2026.

About Compass PathwaysCompass Pathways plc (Nasdaq: CMPS) is a mental health care company dedicated to accelerating patient access to evidence-based innovation in mental health. Our focus is on improving the lives of those who are suffering with mental health challenges and who are not helped by current treatments. We are pioneering the development of a new model of psilocybin treatment, in which our proprietary formulation of synthetic psilocybin, COMP360, is administered in conjunction with psychological support. COMP360 has been designated a Breakthrough Therapy by the U.S. Food and Drug Administration (FDA) and has received Innovative Licensing and Access Pathway (ILAP) designation in the UK for treatment-resistant depression (TRD). We have commenced a phase 3 clinical program of COMP 360 psilocybin treatment in TRD, the largest randomised, controlled, double-blind psilocybin treatment clinical program ever conducted. Previously, we completed a phase 2b study with top line data showing a statistically significant (p<0.001) and clinically relevant improvement in depressive symptom severity after three weeks for patients who received a single high dose of COMP360 psilocybin with psychological support. We are also conducting a phase 2 clinical study of COMP360 psilocybin treatment for anorexia nervosa. Compass is headquartered in London, UK, with offices in New York and San Francisco in the United States. Our vision is a world of mental wellbeing.
