Design outcomes

Primary

MeasureTime frame
MDZ PK parameters, as measured by laboratory analysis of plasma concentrations from blood samples including, but not limited to, the following at multiple timepoints over 25 days: 1. Maximum concentration (Cmax) 2. Time to reach maximum concentration (tmax) 3. Area under the concentration-time curve from time zero to infinity (AUC8) 4. Terminal elimination half-life (t1/2)

Secondary

MeasureTime frame
1. Incidence of treatment-emergent adverse events (TEAEs) and SAEs as reported by the participant continuously over 25 days: 2. MDZ metabolite PK parameters, as measured by laboratory analysis of plasma concentrations from blood samples including, but not limited to, the following at multiple timepoints over 25 days: 2.1 Maximum concentration (Cmax) 2.2 Time to reach maximum concentration (tmax) 2.3 Area under the concentration-time curve from time zero to infinity (AUC8) 2.4 Terminal elimination half-life (t1/2) 3. DNL343 PK parameters, as measured by laboratory analysis of plasma concentrations from blood samples including, but not limited to, the following at multiple timepoints over 25 days: 3.1 AUC during a dosage interval (tau) (AUCt) 3.2 Maximum concentration at steady state (Cmax,ss)
