Oral Glibenclamide in Preterm Infants With Hyperglycaemia (GALOP)

Amglidia®: glibenclamide oral suspension 6 mg/ml administered by gastric tube after dilution to 1/6th in human milk

"* For the first 10 patients during the test phase, four 0.2 ml samples will be taken at H3, H6, H10, and H24 (+/- 1 hour) after the first dose; an additional sample will be taken for patients whose blood sugar levels stabilize beyond 24 hours, after 6 hours of stable blood sugar levels (4-10 mmol/l);~* For subsequent patients included during phase II:~* 1 sample of 0.2 ml within the first 24 hours of treatment, during a care assessment.~* 1 sample of 0.2 ml within the first 24 hours of treatment, during a care assessment~* 1 sample of 0.2 ml per day at each daily check-up as part of care during the treatment period.~* In centers that are unable to perform the samples and the appropriate techniques for centralizing these PK points, these samples will not be taken.~PK parameters of glibenclamide will be determined using nonlinear analysis: area under the plasma concentration time curve (AUC), absorption constant, apparent clearance and volume of distribution."

blood sampling at before first administration and after 24 hours for measurement of C-peptide proinsulin ratio if it is impossible to collect both volumes, the C-peptide collection will be prioritized

"If there are not performed as part of standard care, biological monitoring of ALT, AST, complete blood count, hemostasis, urea, creatinine, blood ionogram, total bilirubin and conjugated bilirubin will be done before first administration at the following time frame : 48 hours after the first administration than each days during treatment period, and 48 hours after the end of treatment.~Transaminases and hemostasis will be done only in case of clinical indication before the first administration."
