Linifanib (ABT-869), enhances cytotoxicity with poly (ADP-ribose) polymerase inhibitor, veliparib (ABT-888), in head and neck carcinoma cells

These data suggest the possibility of combining targeted therapeutic such as linifanib with veliparib to augment the inhibition of cell growth and apoptosis via synthetic lethality in HNSCC cells. Thus, it may provide a novel therapeutic strategy and improve efficacy and outcome in HNSCC.
