Liver cancer is the fourth greatest cause of cancer related mortality. AD80 is a multi-kinase inhibitor with anti-tumoral activity across a variety of hepatocellular carcinoma (HCC) preclinical models, including mouse xenografts. AD80 is highly active in a tumor xenograft model. Experimental dosing for AD80 was determined from maximum tolerated dosage (MTD) studies and pharmacokinetic (PK) analysis. Quantities of AD80 in blood plasma were determined by LC-MS/MS at Medicilon.
