Shattuck Labs, Inc. is moving to focus its clinical efforts on autoimmune diseases with SL-325 after deciding to discontinue its hematology-oncology candidate, SL-172154, due to efficacy that did not reach a high enough bar for overall survival (OS) improvement. The decision marks a strategic shift for the company, which includes a 40% reduction in its workforce, but also yet another blow for the once-promising field of CD47-directed cancer immunotherapies.
