Compass Seeks Funding After Positive Trial Data

Compass said it will sell $150 million of American Depositary Shares (ADS), each representing one ordinary share of the company, and, in the case of certain institutional investors, pre-funded warrants to purchase ADSs. The company also expects to issue underwriters a 30 day option to purchase up to an additional $22.5 million in ADS.

The capital raise comes after Compass said it met the primary endpoint in two Phase 3 trials of COMP360, its proprietary synthetic psilocybin therapy for treatment-resistant depression. The company said COMP360 is the first classic psychedelic to consistently deliver a "statistically significant" and "clinically meaningful" benefit with a well-tolerated safety profile.

In the COMP006 study, patients who received a 25 mg dose of COMP360 showed a significantly greater reduction in depression symptoms than those given a 1 mg dose. Compass said symptom reductions of over 25% were seen in 25% of participants in COMP005 and in 39% of participants in COMP006.

FDA And Data Catalysts Ahead

Compass said it has requested a meeting with the U.S. Food and Drug Administration (FDA) to discuss a rolling review and expects to submit a New Drug Application in the fourth quarter.

Meanwhile, COMP360 is entering late-stage clinical development after the FDA accepted an Investigational New Drug application for the treatment of post-traumatic stress disorder earlier this year. The company also expects to release its 26-week Part B data from the COMP006 study during the third quarter and said it is working to prepare COMP360 for a potential launch before the year’s end.
