Segment Reporting [Abstract] |
Segment Reporting | 17. Segment Reporting The Company operates in one business segment, which includes all activities related to the discovery, development, and potential commercialization of off-the-shelf viral immunotherapies that help patients fight cancer. The determination of a single business segment is consistent with the consolidated financial information regularly provided to the Company’s chief operating decision maker (CODM). The Company’s CODM is its Chief Executive Officer, who reviews and evaluates consolidated net income (loss) for purposes of assessing performance, making operating decisions, allocating resources, and planning and forecasting for future periods. In addition to the significant expense categories included within consolidated net income (loss) presented on the Company's condensed consolidated statements of operations and comprehensive income (loss), see below for disaggregated amounts that comprise research and development and general and administrative expenses:
