Phase I Pharmacokinetic and Biologic Correlative Study of Mapatumumab, a Fully Human Monoclonal Antibody With Agonist Activity to Tumor Necrosis Factor–Related Apoptosis-Inducing Ligand Receptor-1

Abstract

Mapatumumab can be administered safely and feasibly at 10 mg/kg IV every 14 days. The absence of severe toxicities and the attainment of plasma mapatumumab concentrations that are active in preclinical models warrant further disease-directed studies of this agent alone and in combination with chemotherapy in a broad array of tumors.
