Segments | 15. Segments The Company has one operating and reportable segment focused on inventing and developing novel medicines for patients with depression, anxiety, and other debilitating neuropsychiatric disorders using the Company's proprietary Glyph™ Platform. The chief operating decision-maker, or CODM, manages the Company’s operations on a consolidated basis, and assesses performance based on consolidated net loss that is reported on the condensed consolidated statements of operations and comprehensive loss. The CODM makes decisions about allocating resources and assessing performance for the entire company. The measure of segment assets is reported on the condensed consolidated balance sheet as total consolidated assets.
