(B) Fold change in rate of tumor growth for each animal in both young and aged mice after anti-CTLA-4 antibody treatment compared to age-matched untreated mice. 38 mice per group. (C, D) The mice were treated IP at 10 mg/kg twice weekly for a total of 6 doses with a combination of anti-PD-L1 antibody (starting 4 days after tumor cell implantation) and anti-CTLA-4 antibody (starting 7 days after tumor cell implantation).

a Group mean TV from treatment initiation on Day 10 through end of study on Day 34. n = 10 mice/group. All animals survived through Day 34 with exception of one animal in untreated group which exited study on Day 32. SPD suspensions (40 mg/mL) and vehicle were dosed IT on Days 10, 14, 18, and 22 (red triangles). Anti-mCTLA-4 (10 mg/kg) was dosed IP on Days 10, 13, 17, and 20 (black diamonds). The combination group received both SPD and anti-mCTLA-4 on the same schedules as the monotreatments. b Group mean percent change in body weight from treatment initiation on Day 10 through end of study on Day 34. Error bars =  ± SEM. Significance reported for Day 34 versus untreated/vehicle controls; ns not significant, *p
