Fig. 6: CDX0239-PBD demonstrates potent in vivo antitumor activity in ALK-expressing xenograft models.

A Average tumor volume in neuroblastoma xenograft models NB-1, NB-SD, COG-N-424x, SK-N-AS, and NGP ALK wild-type (WT) with 3 weekly treatments of 1 mg/kg CDX0239-PBD (blue line with circles) compared to IgG (gray line with squares) and normal saline vehicle (black line with circles). B Average tumor volume of colorectal carcinoma xenograft models HCT-116 and SW-48 and fusion-positive rhabdomyosarcoma xenograft model RH-41 with 3 weekly treatments of 1 mg/kg CDX0239-PBD (blue line with circles) compared to IgG (gray line with squares) and normal saline vehicle (black line with circles). C Average tumor volume in neuroblastoma xenograft model NB-1 with a single 1 mg/kg dose of CDX0239-PBD (blue line with circles) compared normal saline vehicle (black line with circles). D Average tumor volume in neuroblastoma xenograft model NGP ALK knockout (KO) with 3 weekly treatments of 1 mg/kg CDX0239-PBD (blue line with circles) compared to IgG (gray line with squares) and normal saline vehicle (black line with circles). All data are plotted as mean ± standard deviation with n = 5 mice per treatment condition for all experiments, and each experiment was completed once. All p-values represent CDX0239-PBD vs vehicle tumor volumes using a square root transformation analysis with linear mixed effects model.
