In eight tumors where patients failed immune checkpoint inhibitor (ICI) treatment, Plinabulin + radiation + PD-1 inhibitors demonstrated an overall response rate (ORR) of 23% and a disease control rate (DCR) of 54% in non-irradiated lesions. Biomarker analysis linked Plinabulin’s mechanism to GEF-H1–dependent dendritic cell maturation, offering the potential to pre-select patients at baseline and predict clinical response.... Read More
