a Treatment regimen illustrating the schedule of delivery of anti-TGFβ (pan or isoform-specific inhibition) with either anti-CTLA-4 or anti-PD-1 therapy beginning 11 days post tumor implantation. Anti-TGFβ therapy was given via intraperitoneal injection (200 µg/mouse) every other day for a total of 8 doses. Anti-CTLA-4 (clone 9H10) was given via intraperitoneal injection (100 µg/mouse) every 3 days for a total of 3 doses. Anti-PD-1 was given via intraperitoneal injection (250 µg/mouse) every 3 days for a total of 5 doses. b Tumor growth curves for indicated treatment combinations with anti-CTLA-4. c Tumor growth curves for indicated treatment combinations with anti-PD-1. Data shown are representative of two independent experiments ± SEM. Statistics were calculated 24 days post tumor implant (n = 10 mice/group) using 2-way ANOVA. Only statistically significant differences among untreated and treated groups are shown. *p < 0.05; **p < 0.005; ***p < 0.0005; ****p < 0.0001.
