- More than half of the patients demonstrated remission of depression at 18 months, after a single dose of 25mg investigational COMP360 psilocybin with psychological support
- Open label phase 2 study, conducted by Sunstone Therapies and scheduled to be presented at the ASCO annual meeting on June 5, is believed to be the longest clinical study of psilocybin ever conducted
LONDON, May 26, 2023 (GLOBE NEWSWIRE) -- COMPASS Pathways plc (Nasdaq: CMPS) (“COMPASS”), a mental health care company dedicated to accelerating patient access to evidence-based innovation in mental health, today announced that new long-term efficacy data of investigational COMP360 psilocybin in cancer patients with major depressive disorder will be presented at the Annual Meeting of the American Society of Clinical Oncology (ASCO).
More than half of the patients (16/28) treated with a single dose of 25mg COMP360 psilocybin with psychological support remained in remission from their depression at 18 months post administration. The investigator-initiated study, led by Manish Agrawal, MD, at Sunstone Therapies, is believed to be the longest study of psilocybin therapy ever conducted.
The trial was a phase 2, single-center, fixed-dose, open-label study in 30 patients with curable and incurable cancer and major depressive disorder. Patients were treated with a single dose of 25mg of COMP360 psilocybin, administered simultaneously in group cohorts of 3-4, with group and individual psychological support, and evaluated at 8 weeks and 18 months. Of 30 patients from the parent study, 28 were enrolled in the follow-up study. Key results:
- 18/28 patients (64.2%) demonstrated sustained clinical response from baseline to 18 months follow-up
- 16/28 patients (57.1%) demonstrated remission of depression at 18 months
The original phase 2 study conducted by Sunstone was completed in 2021 and results were published in JAMA Oncology in April 2023.
Guy Goodwin, MD, Chief Medical Officer, COMPASS Pathways, said: “This study conducted by Sunstone Therapies is extremely encouraging and demonstrates the potential durability of COMP360 psilocybin therapy. COMPASS Pathways is looking at the long-term effects of COMP360 in our phase 3 programme in treatment-resistant depression.”
Manish Agrawal, MD, Chief Executive Officer, Sunstone Therapies, and the trial’s Principal Investigator, said: “This pioneering study is the first of its kind, conducted within a community hospital cancer center. The results show significant improvement in these patients’ depression symptoms long-term and, if replicated in larger studies, could open the door to a wider and faster adoption of psilocybin therapy in the future.”
COMP360 is COMPASS’s investigational proprietary formulation of synthetic psilocybin, administered in conjunction with psychological support. COMPASS is currently conducting a phase 3 clinical program of COMP360 psilocybin therapy in treatment-resistant depression (TRD), the largest of its kind ever conducted. This program follows positive results from COMPASS’s phase 2b study published in the New England Journal of Medicine.
