| Bioactivity | Veledimex (INXN-1001), a synthetic analog of the insect molting hormone ecdysone, is an orally active activator ligand for a proprietary gene therapy promoter system. Veledimex can be used to activate certain genes using the ecdysone receptor (EcR)-based inducible gene regulation system, the RheoSwitch Therapeutic System (RTS). Veledimex can cross blood-brain barrier (BBB) in both orthotopic GL-261 mice and cynomolgus monkeys[1][2]. | ||||||||||||
| In Vivo | Veledimex (INXN-1001) generally has moderate to low oral bioavailability after a single oral administration in mice and monkeys (-56% in mice and up to 17.4% in cynomolgus monkeys) with mostly low plasma clearance (1399 and 1170 mL/h per kilogram in mice and monkeys, respectively), high volume of distribution (20271 and 9180 mL/h per kilogram in mice and monkeys, respectively), and long terminal half-lives (-10 hours in mice and -30 hours in monkeys) after intravenous administration[1]. Ad-RTS-mIL-12 + Veledimex have demonstrated a dose-related increase in tumor IL-12 mRNA and IL-12 protein expression. Discontinuation of Veledimex resulted in a return to baseline IL-12 mRNA and protein expression in numerous syngeneic mouse tumor models. Veledimex crosses the blood-brain-barrier in both naive and orthotopic GL-261 mice with increased brain tissue level of -6 fold observed in tumor bearing vs. normal mice. Ad-RTS-mIL-12 + veledimex demonstrate a dose-related increase in survival without significant adverse events[2]. | ||||||||||||
