On February 29, 2024, Gritstone issued a press release “announc[ing] an approximately 40% reduction of its workforce”, stating that “[t]he move comes following the recently 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.”
