A clinical study investigating the pharmacokinetic interaction between NN703 (tabimorelin), a potential inhibitor of CYP3A4 activity, and midazolam, a CYP3A4 substrate

Objective NN703 (tabimorelin) is an orally active growth hormone (GH) secretagogue intended for use as an alternative to daily injections of GH. In vitro studies in human liver microsomes have indicated that NN703 is a mechanism-based inhibitor of CYP3A4. The aim of the present study was to investigate in man the effects of NN703 on the pharmacokinetics of midazolam, a substrate of CYP3A4.
