PPL-100, is a phosphorylated Pro-drug of Procyon's PL-100 protease inhibitor. PL-100 is the active antiviral agent that is potent, specific and non-cytotoxic with a favorable cross-resistance profile in drug and multi-drug resistant strains of HIV-1. PL-100 is active against several HIV-1 strains specifically selected for key mutations that render these strains resistant to currently-marketed protease inhibitors. Preclinical safety studies as well as animal pharmacokinetic studies have recently been completed and human clinical studies expected to commence by the end of the year.
