E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To perform a double-blind randomized placebo controlled multicenter study with darbepoetin in infants with MRI confirmed PAIS and to investigate whether darbepoetin can reduce brain injury in neonates who suffered from perinatal arterial ischemic stroke (PAIS). The ultimate goal of this study is therefore to develop a therapy using erythropoiesis-stimulating-agents (ESAs) such as darbepoetin to reduce or even prevent lifelong consequences of PAIS-related brain injury in this group of term newborns. |
Het uitvoeren van een dubbel-blind gerandomniseerd placebo-gecontroleerde multicenter studie met darbepoëtine in pasgeborenen met op de MRI bevestigde perinatale arteriële ischemische stroke (PAIS) en te onderzoeken of darbepoëtine hersenschade kan reduceren in pasgeborenen met PAIS. Het einddoel van de studie is daarom om door het gebruik van erytropoese-stimulerende factoren zoals darbepoëtine een therapie te ontwikkelen welke de levenslange consequenties van PAIS-gerelateerde hersenschade bij deze kwetsbare groep pasgeborenen reduceert dan wel voorkomt. |

E.5 End points |
E.5.1 | Primary end point(s) |
Our primary objective is to determine whether there is a difference in the degree in stroke tissue loss between darbepoetin and placebo treatment, which will be measured by the change in lesion size and brain growth between the time of onset of the insult and 6-8 weeks of age. Additionally we will assess whether there are differences between darbepoetin and placebo treatment in DTI parameters of selected regions of interest. Primairy endpoints will be estimated using advanced volumetric magnetic resonance (MRI) techniques and diffusion tensor imaging (DTI) MRI techniques, performed within 3 days after clinical presentation and at 6-8 weeks of age. |
Onze primaire uitkomstmaat is om te bepalen of er een verschil is in de mate van hersenschade en weefselverlies tussen de met darbepoetin en met placebo behandelde groep. Dit zal worden bepaald door de verandering in infarctgrootte en hersengroei tussen het moment van diagnose en de leeftijd van 6-8 weken te meten en te vergelijken tussen de groepen. Daarnaast zullen we kijken naar verschillen tussen de met darbepoetin en met placebo behandelde groepen wat betreft DTI parameters in verschillende regio's. Primaire eindpunten worden gemeten met behulp van geavanceerde volumetrische MRI-technieken en diffusion tensor imaging (DTI) MRI technieken, gemaakt binnen 3 dagen na klinische presentatie en op de leeftijd van6-8 weken. |

6-8 weeks postnatal age. |
6-8 weken postnatale leeftijd. |
|
E.5.2 | Secondary end point(s) |
We will assess development of USCP, and cognitive development at 18 months of age using the BSID-III and PSOM scores as well as a full neurological assessment including Gross Motor Function Classification system (GMFCS) and several handfunction tests such as Manual Ability Classification System (MACS), the Hand Assessment of Infants (HAI) and Assisting Hand Assessment (AHA) and compare them between groups (darbepoetin vs placebo). |
We zullen de neuromotore ontwikkeling vergelijken tussen de darbepoetine en met placebo behandelde groep. Hierbij zal worden gekeken naar de ontwikkeling van unilaterale spastische cerebrale parese (USCP) en de cognitieve ontwikkeling op de leeftijd van 18 maanden. Deze zullen worden onderzocht met behulp van de Bayley Scales of Infant Development (BSID) versie 3 en de Pediatric Stroke Outcome Measure (PSOM) Daarnaast zal op de leeftijd van 18 maanden ook een volledig neurologisch onderzoek inclusief de Gross Motor Function Classification system (GMFCS) en verschillende handfunctietesten zoals de Manual Ability Classification System (MACS), the Hand Assessment of Infants (HAI) and Assisting Hand Assessment (AHA) plaatsvinden. |
