The mean final tumor volumes (mean ± SD, mm3) were PBS, 1754.8 ± 207.6; VEGF-siRNA LNP, 1608.2 ± 224.5; anti-PD-L1 antibody-modified scramble-siRNA LNP, 1377.3 ± 205.8; isotype control antibody-modified VEGF-siRNA LNP, 979.8 ± 115.7; and anti-PD-L1 antibody-modified VEGF-siRNA LNP, 579.2 ± 68.3. Here, VEGFA is linked to neoplasm.
