Superior antitumor response by adoptively transferred T cells with NKTR-214 compared to IL-2. a Schematic of the pmel-1 ACT model. Time points in days throughout the text refer to the number of days post-administration of ACT + NKTR-214 or ACT + IL-2 at day 0. Subsequent to day 0, no further ACT was given. A second dose of either NKTR-214 (one dose) or IL-2 (qdx3) was given at day 9 and day 18 per the q9dx3 dosing regimen. b Changes in mean tumor volume over time. Data are means ± s.e.m (n = 12). *p < 0.0001 compared to ACT + IL-2; #p < 0.0001 compared to vehicle (two-way ANOVA, with Bonferroni-Dunn multiple comparisons test). (c)Tumor growth delay was assessed for each tumor growth curve by interpolating the time to achieve tumor volume of 1000 mm3. #p < 0.0001 compared to ACT + IL-2 (Log-Rank Mantel–Cox test). The experiment is representative of three replicates.
