ACTIVE MOIETY
IDX320: Idenix researchers presented 2 posters on IDX320, an non-covalent NS3/4A HCV protease inhibitor further back in the development pipeline.; L.B. Lallos and colleagues reported that IDX320 interfered with HCV protease activity in laboratory studies using purified proteases, an HCV replicon model, and an infectious HCV virus in cell cultures. IDX320 was found to bind tightly to the HCV NS3/4A protease, with a dissociation half-life of more than 9 hours. The drug inhibited the protease enzyme of HCV genotypes 1a, 1b, 2a, and 4a, as well as 3a at a higher concentration. In contrast, it did not interfere with 9 human cellular proteases.; In the second poster, S.S. Good and colleagues reported preclinical pharmacokinetic and safety data from laboratory and animal studies. IDX320 had good bioavailability, with a mean plasma half-life of 6 hours in mice and 10 hours in monkeys after a 2 mg/kg IV dose. The drug was highly protein bound. Of the 8 human CYP450 enzymes that process drugs in the liver, only 3A4 metabolized IDX320, and the drug in turn did not significantly inhibit 5 of these enzymes.
