Gritstone reduced workforce by 40% in February

In February 2024, Gritstone bio reduced its workforce by approximately 40% to reduce costs and preserve capital. The reduction primarily impacted employees associated with vaccine manufacturing and clinical infectious disease operations, who were not active in the ongoing Phase 2 study of GRANITE, Gritstone’s personalized cancer vaccine. The reduction occurred approximately two weeks following the previously announced delay of the proposed CORAL Phase 2b study, which resulted in Gritstone not receiving external funding it previously anticipated beginning in 1Q 2024, associated with the initiation of the study.
