E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To estimate the optimal dose of bumetanide for use in neonatal seizures not responding to phenobarbitone (standard therapy). This optimum dose will be that which achieves the maximum seizure reduction with an acceptable safety profile. |
|
E.2.2 | Secondary objectives of the trial |
• To assess the feasibility of neonatal seizure treatment with bumetanide in babies with HIE and seizures that are not responding to phenobarbitone alone • To assess whether bumetanide reduces the need for rescue medication. • To assess bumetanide as a diuretic in babies with hypoxic ischemic encephalopathy. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Male or female term baby with gestational age of 37-43 weeks and postnatal age <48 hours One or more of the following: o APGAR score < 5 at 5 mins. o Umbilical cord or first arterial blood sample pH < 7.1 or base deficit >16 mmol/L. o Postnatal resuscitation still required 10 minutes after birth Clinical evolving encephalopathy Received one dose of standard anticonvulsive therapy (phenobarbitone, 20mg/kg) for clinical or electrographic seizures. Electrographic seizures more than cumulative 3 minutes over a period of 2 hours or ≥ 2 seizures with durations of 30 seconds each within a 2-hour window within the first 48 hours of life and after administration of one standard (20mg/kg) dose of phenobarbitone. Written informed consent of parent or guardian. EEG monitoring has commenced within the first 48 hours of birth. |
|
E.4 | Principal exclusion criteria |
Suspected or confirmed brain malformation, inborn error of metabolism, genetic syndrome, or major congenital malformation Congenital (in utero) infection (TORCH) if known Babies who have received diuretics such as furosemide or bumetanide in routine clinical management within the last 24 hours. On any other anticonvulsive medication other than phenobarbitone or bolus of midazolam / pentobarbitone for intubation. Severe electrolyte depletion (Na < 120 mmol/L, K <3.0 mmol/L) |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Stage 1 The optimal dose is defined as achieving effective seizure reduction: Defined as reduction of electrographic seizure burden by >80% within 12 hours after bumetanide administration over a 2 hour epoch compared to a 2 hour epoch prior to Bumetanide administration. No need for rescue AED within 48 hours Safety: acceptable safety profile Absence of Suspected Unexpected Serious Adverse Reactions (SUSARs) Serious Adverse Reactions (SAR) which are at least probably related in <10% Clinically acceptable frequency of adverse reactions * Severe hypokalaemia (<2.8mmol/l) and/or ECG changes in <10% * Severe dehydration (weight loss >10% over 24 hours with hypotension) in <10% Stage 2 PK measurements (bumetanide at the optimal dose) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
