Frequently asked questions about EMP-01

What is EMP-01?

EMP-01 is an investigational small molecule being developed by AtaiBeckley Inc. for the treatment of social anxiety disorder. It is a psychiatric candidate that has completed a Phase 2 clinical trial. EMP-01 has not been approved by any regulatory agency and remains in clinical development.

What is EMP-01 used for?

EMP-01 is being studied for social anxiety disorder, a psychiatric condition characterized by intense fear or anxiety in social situations. Its clinical program has focused on this single indication. Because EMP-01 is still investigational, it is not available as a prescribed treatment outside of clinical research.

What does EMP-01 target?

EMP-01 targets the 5-HT2A receptor, also written as 5-HT2AR, a serotonin receptor. The 5-HT2A receptor is a G protein-coupled receptor that mediates effects of serotonin in the brain. EMP-01 is a small molecule designed to act at this receptor target.

Who is developing EMP-01?

EMP-01 is being developed by AtaiBeckley Inc., which trades under the ticker ATAI. The company is the sponsor of the drug's clinical program in social anxiety disorder. AtaiBeckley is a psychiatry-focused biopharmaceutical company.

What phase is EMP-01 in?

EMP-01 is in Phase 2 development. Its Phase 2 trial in social anxiety disorder has been completed, and no trials are currently listed as active. EMP-01 is investigational and has not received FDA approval.

What clinical trials is EMP-01 in?

EMP-01 has been evaluated in one clinical trial, NCT06693609, titled Exploratory Safety and Efficacy of EMP-01 in Social Anxiety Disorder. The Phase 2 study was completed, enrolled 70 participants, was randomized, double-blind, and placebo-controlled, and was conducted in the United Kingdom in adults aged 18 years and older.
