Responses of Ewing sarcoma xenografts to CP-751,871, rapamycin or the combination treatment.
Responses of osteosarcoma xenografts to CP-751,871, rapamycin or the combination treatment.
Tumor-bearing mice were treated with CP-751,871 (0.25 mg/mouse twice weekly × 4). Rapamycin (5 mg/kg daily × 5 per week for up to 12 consecutive weeks) or the combination of CP-751,871 and rapamycin. Tumor diameters were measured weekly.
Left panels: Kaplan Meier event free survival (EFS). Control (black), CP-751,871 (green), rapamycin (blue) or CP-751,871 + rapamycin (red). Curves show the probability of mice being event-free (tumor volume < 4-fold that at initiation of treatment) against days post treatment initiation.
Center panels: Growth of individual tumors; Controls (light gray), CP-751,871 treated (black). Right panels: Growth of individual tumors; Rapamycin (light gray), CP-751,871 + rapamycin treated (black).
