Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To examine the pharmacokinetics of different prednisolone formulations i.e. crushed tablets and oral solutions to characterise its bioavailability relative to standard whole tablets (controls).Herein compare the AUC, Cmax and Tmax;Secondary Objective: • Tolerability of different formulations assessed by number of doses swallowed, patient preferences and vomiting. • Adverse events • Modified Pulmonary Index Score (MPIS) and Paediatric Early Warning Score (PEWS) • Validation of the saliva samples by using plasma samples;Primary end point(s): Concentration-time data on prednisolone concentration measured in saliva to determine AUC, Tmax and Cmax. ;Timepoint(s) of evaluation of this end point: Every patient is randomized to one of two time schedules for saliva sampling: T0, T0.5, T1.5, T2.5, T3.5, T7, T11 T0, T1, T2, T3, T4, T8, T12 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Tolerability of different formulations measured by the Wong-Baker FACES scale • Adverse events • MPIS and PEWS score at administration time for dose 1 and 2 • Concentration-time data on prednisolone concentration measured in plasma to determine AUC, Tmax and Cmax ;Timepoint(s) of evaluation of this end point: Tolerability is evaluated at each dose. Adverse events, MPIS and PEWS score are evaluated at baseline and at each dose. Plasma samples are only obtained if an intravenous access already exists, sampling time will follow the same schedule as saliva sampling. | — |
