Restructuring and Related Activities [Abstract] |
Restructuring | 9. Restructuring On March 7, 2025, the Company committed to a plan to reduce its workforce by approximately 13% as part of its cost reduction initiatives in order to align resources with the Company’s strategic priorities, including advancing its preclinical and research pipeline. The Company initiated a reduction in force impacting approximately 25 employees across the organization. For the six months ended June 30, 2025, the Company incurred restructuring costs of approximately $2.3 million, primarily consisting of personnel expenses such as salaries, severance payments, and other benefits. Cash payments related to these expenses were paid out in 2025. On October 21, 2025, the Company committed to a plan to reduce its workforce, which impacted approximately 47% of its workforce, in order to align resources with the Company’s strategic priorities, following the results of the Phase 3 INFRONT-3 clinical trial evaluating the safety and efficacy of latozinemab in individuals with frontotemporal dementia due to a progranulin gene mutation (FTD-GRN). Total incremental restructuring charges associated with the reduction in force were approximately $7.0 million, consisting primarily of severance and related termination benefits. Cash payments related to these expenses were paid out and the reduction in force was completed during the first half of 2026. For the three and six months ended June 30, 2026, the Company recorded a reduction of less than $0.1 million and $0.4 million, respectively to previously recognized restructuring costs, primarily due to lower-than-expected related termination benefits and this was included in operating expenses.
