High PD-L1 protein and gene expression were associated with improved PFS

TUMOR, SOLID TUMORS
Next, we asked whether expression of PD-L1 as the primary drug target is associated with improved PFS in children. PD-L1 IHC was performed on available baseline tumor samples from iMATRIX-atezo. PD-L1 expression on immune cells ranged from 0 to 60% (median 0.5%) and was higher in lymphoma versus solid tumors (Fig.
