Pharmacokinetic Evaluation of MDZ028

Study Overview
=================
Brief Summary
-----------------
Plasma concentration data were collected from 37 paedriatic patients and 12 healthy adults recruited in a single dose, open-label phase II pharmacokinetic study and in a single dose, randomised, open-label two-peiod crossover bioavailability study, respectively. Data were analysed using non-linear mixed effect modeling.

Detailed Description
-----------------
In the absence of a licensed formulation in many countries worldwide, ADV6209, an innovative 2mg/ml oral solution of midazolam containing cyclodextrin, has been developed for moderate sedation in paediatric patients. Population pharmacokinetics for ADV6209 is reported. Plasma concentration data were collected from 37 paedriatic patients and 12 healthy adults recruited in a single dose, open-label phase II pharmacokinetic study and in a single dose, randomised, open-label two-peiod crossover bioavailability study, respectively. Data were analysed using non-linear mixed effect modeling. Plasma concentrations of midazolam were discribed by a two-compartement model. An additional one-compartement model was added for a α-hydroxymidazolam.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetic analysis of the oral solution of midazolam (ADV6209) | The Aim of the study was to assess the pharmacokinetic analysis of an oral solution of midazolam (ADV6209) oral formulation in paedriatic patients from 6 months to 18 years ols in order to support dosing recommendations. All subjects received a single 0.3mg/kg midazolam dose of ADV6209, without exceeding a total dose of 10 mg.Population pharmacokinetic modelling was performed to characterise the concentration-time course of midazolam and its main active metabolite, and to evaluate the changes in clearance and volume of distibution in the different age groups. | 1 day |
