Effect of Clarithromycin on PK of Linaprazan, Linaprazan on PK of Clarithromycin and Linaprazan on PK of Midazolam

This is a phase I, open-label, fixed sequence design, drug-drug-interaction (DDI) study divided in 2 parts. Part I is designed to evaluate whether concomitant treatment with linaprazan glurate and clarithromycin, a strong inhibitor of cytochrome P450 3A4 (CYP3A4) and P-glycoprotein P (PgP), leads to an effect on the systemic exposure to linaprazan glurate and linaprazan and whether there is an effect on the pharmacokinetics of clarithromycin after a single dose of linaprazan glurate. Part II is designed to evaluate the effect of repeated doses of linaprazan glurate on the pharmacokinetics (PK) of a sensitive substrate of CYP3A (midazolam).
