Hypoxic ischemic encephalopathy
Conditions
Brief summary
Primary endpoint of step 1 will be the measured plasma concentrations of Sildenafil., Primary endpoint of step 2 will be survival without brain lesions at hospital discharge on brain MRI. The MRI will be performed between the end of rewarming (day 3.5) and day 5
Detailed description
Step 1: estimated clearance parameters and volumes of distribution for IV sildenafil, Step 1: area under the plasma sildenafil concentration-time curve and the maximum plasma sildenafil concentration achieved (individual exposure), Step 1: brain damage-free survival at hospital discharge on MRIs performed between 3.5 to 5 days and/or 10-30 days” (treatment efficacy), Step 2: Secondary end-points, related to potential benefits, will be based on changes in EEG patterns, detailed analysis of MRIs and spectroscopy, and 2-year assessment (neurodevelopmental impairment, autism spectrum disorders assessed using M-CHAT (Modified Checklist for Autism in Toddlers), PARCA-R and Parenting Stress Index-Short Form (PSI-SF)., Step 2: Secondary end-points, related to safety, will include incidence of low systemic pressure requiring hemodynamic support, and cardiac function assessment.
