E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To obtain paediatric pharmacokinetic data of enalapril and its active metabolite enalaprilat in patients treated with enalapril ODMTs to describe the dose exposure in the paediatric population with CHD.
|
|
E.2.2 | Secondary objectives of the trial |
• To demonstrate safety, in particular renal safety, of enalapril ODMTs in children with CHD.
• To characterise the dose/safety relationship from a starting dose to an optimal maintenance dose.
• To explore the dose exposure/response relationship with pharmacodynamic parameters in the paediatric population with CHD.
• To investigate the Shortening Fraction (SF) of the heart muscle by echocardiography.
• To investigate the acceptability and palatability of enalapril ODMTs in the paediatric population with CHD.

E.5 End points |
E.5.1 | Primary end point(s) |
The bioavailability of enalapril and its active metabolite enalaprilat in young children (AUC from 0 to time of last sampling point, Cmax and Tmax); descriptive pharmacokinetic investigation.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
PK/PD profile sampling timepoints: Visit day 1: pre-dose, 0h, 2, 4, 6, 8, 12 hours |
|
E.5.2 | Secondary end point(s) |
1. The bioavailability of enalapril and its active metabolite enalaprilat in the different age subsets (0 to ˂12 months and 12 months to ˂6 years) of the paediatric study population (AUC from 0 to time of last sampling point, Cmax and Tmax); descriptive pharmacokinetic investigation.
2. Markers of the renin-angiotensin-aldosterone system as exploratory pharmaco-dynamic investigation.
3. Brain natriuretic peptides (BNPs).
4. Acceptability and palatability of the novel formulation.
5. Safety parameters including blood pressure and renal function.
6. Echocardiography (Shortening Fraction)
7. Rehospitalisation due to heart failure.
8. Death due to worsening of the underlying disease.
9. Pharmacodynamic and efficacy endpoints analysis to differentiate high and low output disease.
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Biochemistry, Urine and BNP collected during each visit in the hospital to monitor renal function.
PK and PD 1 sample collected during each visit, unless the patient
terminated use of the IMP, then only PD sample is collected.
Acceptability and Palatability questionnaire is completed during initial
visit, once stable dose is reached and during end of study visit. |
