TAK-960 is an orally bioavailable, selective inhibitor of Plks with IC50 values of 0.8, 16.9, and 50.2 nM for Plk1, Plk2, and Plk3, respectively.

FES/FPS:58.2 nM, MLCK/MYLK:25.6 nM, PLK2:16.9 nM, PLK1:0.8 nM, PLK3:50.2 nM, PTK2/FAK:19.6 nM

CRC cell lines demonstrated a variable anti-proliferative response to TAK-960 with IC50 values ranging from 0.001 to >?0.75 μmol/L. Anti-proliferative effects were sustained after removal of drug. Following TAK-960 treatment a highly variable accumulation of mitotic (indicating cell cycle arrest) and apoptotic markers was observed. TAK-960 treatment induced G2/M arrest and polyploidy. Six out of the eighteen PDX models responded to single agent TAK-960 therapy (TGII

Fifty-five CRC cell lines and 18 PDX models were exposed to TAK-960 and evaluated for proliferation (IC50) and Tumor Growth Inhibition Index, respectively.?Additionally, 2 KRAS wild type and 2 KRAS mutant PDX models were treated with TAK-960 as single agent or in combination with cetuximab or irinotecan.?TAK-960 mechanism of action was elucidated through immunoblotting and cell cycle analysis[1].
