Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the non-inferiority of the sedative properties of continuous intravenous (i.v.) clonidine compared to continuous i.v. midazolam in mechanically ventilated children and adolescents (0 - <18 years) admitted to a paediatric intensive care unit (PICU).; Secondary Objective: - To evaluate the safety and tolerability (including withdrawal effects) of clonidine compared with midazolam in ventilated children and adolescents admitted to PICU. - To determine clonidine dose-dependent effects on sedation. - To establish the pharmacokinetics - pharmacodynamics (PK-PD) relationship of clonidine for sedation in PICU. - To compare the cumulative total morphine consumption/kg between the two arms in the first 48 hours of investigational medical product (IMP) administration. - To determine if candidate genes predict adequate response to clonidine and midazolam in critically ill paediatric patients. - To identify polymorphisms of clinical relevance to the sedative action of clonidine, midazolam and morphine. - To correlate midazolam pharmacokinetics to polymorphisms of candidate genes. - To correlate clonidine pharmacokinetics to polymorphisms of candidate genes. -To correlate morphine pharmacokinetics to polymorphisms of candidate genes. ;Primary end point(s): proportion of subjects receiving clonidine with sedation failure compared to those subjects receiving midazolam;Timepoint(s) of evaluation of this end point: Sedation and pain assessed at: baseline/ randomization, treatment period, completion visit, post dose monitoring for up to 24 hours.

Secondary

MeasureTime frame
Secondary end point(s): • Primary PK parameters: clearance (CL), volume of distribution (VD) and inter-compartmental clearance (Q), Cmax, AUC, t1/2, Csteady state, Ctrough. • PKPD modeling. • PKPD covariate model • Safety and tolerability assessments • Extent of withdrawal effects. • The extent of delirium. • Rebound hypertension. • Percentage of respiratory depression per group. • Adverse event reporting of symptoms indicative of post-ICU stress. • Neurodevelopment. • CYP3A4, CYP3A5, CYP2D6, COMT, OPRM1, OCT1 and UGT2B7 polymorphisms (additional polymorphisms are listed in protocol). ; Timepoint(s) of evaluation of this end point: • PK parameters: treatment period, completion visit, post dose monitoring. • Safety and tolerability assessments: treatment period, completion visit, post dose monitoring, follow up (14 days post final dose and 1 year post final dose [neonates only]). • Extent of withdrawal effects, including the extent of delirium: treatment period, completion visit, post dose monitoring for at least 24 hours. • Rebound hypertension: for at least 72 hours post cessation of treatment. • Respiratory depression: during re-intubation apnaea in treatment period, completion visit, post dose monitoring every 24 hours. • Neurodevelopment: at 12 months after cessation of IMP (neonates only). • Polymorphisms: On 1 day of treatment period only.
