LONDON & NEW YORK / Oct 31, 2024 / Business Wire / Compass Pathways plc (Nasdaq: CMPS) (“Compass”), a biotechnology company dedicated to accelerating access to evidence-based innovation in mental health, today reported its financial results for the third quarter 2024 and an update on recent business progress.

“Ensuring the success of our lead COMP360 program is our absolute priority. We remain confident that COMP360 can be an effective therapy for patients with serious mental illness and our focus on delivering new treatment options for patients living with treatment-resistant depression remains paramount,” said Kabir Nath, Chief Executive Officer of Compass Pathways. “The shift in the phase 3 pivotal program timeline has forced us to look carefully at our operations and ensure that every resource is focused on this goal. As such, we have made the difficult decision to reduce our workforce and exit activities that are not directly tied to the completion of the trials, regulatory filing and commercialization if approved. These are necessary strategic decisions that we believe will position the COMP360 program for success.”

Business highlights

COMP360 psilocybin treatment in TRD

The phase 3 clinical program of COMP360 psilocybin treatment in TRD is the largest randomized, controlled, double-blind psilocybin treatment clinical program ever conducted. Top-line pivotal COMP005 trial data is expected in the second quarter 2025. In addition, as a result of the increased regulatory scrutiny on functional unblinding, the company has decided to shift the data release for COMP006 until after the 26-week time point and the completion of the blinded portion has been reached for all patients to protect against the risk of unblinding. With this change, Compass now expects data for COMP006 in the second half of 2026.

Prioritization of resources

As a result of changing timelines for the phase 3 trials, we will be reducing our workforce by approximately 30%, including eliminating some senior management positions, to further focus the organization and its capital resources on successfully delivering the COMP360 program. Our non-COMP360 preclinical efforts will be stopped and we are exploring a potential externalization for our digital health tools.
