E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Stage 1 : To estimate the optimal dose of bumetanide in neonatal seizures not responding to phenobarbitone. This optimum dose will be that which achieves the maximum seizure reduction with an acceptable safety profile when used in addition to standard therapy (second dose of phenobarbitone) in > 50% of patients.
Stage 2 : To assess the pharmacokinetics of bumetanide when given at the optimal dose as an add-on to phenobarbitone for neonatal seizures not responding to the first dose phenobarbitone. |
|
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 a first dose of phenobarbitone alone.
- To assess whether bumetanide reduces the need for rescue medication.
- To assess bumetanide as a diuretic in babies with HIE.

- Anuria / renal failure defined as serum creatinine > 200 micromol/L.
- 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 defined as achieving effective seizure burden:
- Reduction of electrographic seizure burden by ≥ 80% during the 3rd and 4th hour after the first bumetanide administration compared to a 2 hour epch prior to Bumetanide administration.
- No need for rescue AED within 48 hours.
*An acceptable safety profile at any time within 48 hours after the first dose is defined as
- 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 dehydratation (dehydration with hypotension (mean BP < 35 mmHg persistent > 1 hour) which requires inotropic support) in < 10%.
◦ Stage 2 :
PK measurements (bumetanide at the optimal dose) |
|
E.5.2 | Secondary end point(s) |
Stage 1
* PK measurements
* Overall seizure control within the first 24 hr after bumetanide administration evaluated after the end of trial
Stage 2
* Safety of bumetanide in babies with HIE
* Overall seizure control within the first 24 hr after bumetanide administration evaluated after the end of trial |
