In vivo activity of JNJ-28871063 in human tumor xenograft models

All dosing was carried out in groups of 8 mice. TGI was calculated as the difference between the change in control and drug-treated tumor volumes on the last day of the study. Statistical significance was evaluated by comparing the mean tumor size of control groups with drug-treated groups using a two-tailed Student's t test.
