Segment Reporting [Abstract] |
Segment Information | 12. Segment Information The Company operates and manages its business as a single operating and reportable segment for the purpose of assessing performance and making operating decisi ons. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the Company’s chief operating decision maker, or decision-making group (the “CODM”), in deciding how to allocate resources and assess performance. The Company’s chief executive officer, who is the CODM, reviews the Company’s financial information on an aggregated basis for pu rposes of evaluating financial performance and allocating resources. The CODM assesses operating performance as compared to planned activities for the operating segment and decides how to allocate resources based on net loss that also is reported on the consolidated statement of operations and comprehensive loss. As a single reportable segment entity, the Company’s segment performance measure is net loss. In addition to the significant expense categories included within consolidated net loss presented in the condensed consolidated statements of operations and comprehensive loss, the below table sets forth disaggregated amounts that comprise research and development expenses and general and administrative expenses (in thousands):
