Initial testing (stage 1) of mapatumumab (HGS-ETR1) by the pediatric preclinical testing program.


Journal Article

Mapatumumab (HGS-ETR1) is a fully human IgG1 agonistic monoclonal antibody that exclusively targets and activates tumor necrosis factor-related apoptosis-inducing ligand receptor 1 (TRAIL-R1). It was tested in vitro at concentrations from 0.01 to 100 microg/ml and in vivo at a dose of 10 mg/kg administered intraperitoneally using a twice-weekly schedule. Mapatumumab demonstrated limited activity against the 23 cell lines of the PPTP in vitro panel with no lines achieving 50% growth inhibition. Mapatumumab induced significant differences in event-free survival distribution compared to controls in 9 of 37 evaluable solid tumor xenografts tested, but in none of the 8 ALL xenografts.
