Biodesix presented preliminary data evaluating a blood-based PD-L1 assay to identify patients who may benefit from cancer immunotherapies. The data were presented last week at the AACR-NCI-EORTC conference. The study was conducted in collaboration with Dr. Michael Pritchett, from FirstHealth Moore Regional Hospital, Pinehurst Medical Clinic, and Dr. Jiaxin Niu, from Banner MD Anderson Cancer Center.
