Brief Summary:
The aim of the study is to perform a randomized double-blind placebo controlled prospective study in newborn infants with MRI confirmed Middle Cerebral Artery (MCA) Perinatal Arterial Ischemic Stroke (PAIS) with darbepoetin. It will be investigated whether intravenous administered darbepoetin can induce the formation of neuronal tissue and restore brain function in neonates who suffered from PAIS compared to placebo treated controls. The ultimate goal of this study is therefore to develop a therapy using erythropoiesis-stimulating agents (ESA) such as darbepoetin to reduce or even prevent lifelong consequences of PAIS-related brain injury in this group of term newborns.

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 80 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: An international multicenter, randomized placebo controlled intervention study
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: This will be a double-blinded study, meaning that both the patient (and his/her parents) and the health care providers, including neonatologist, pediatrician, nurses, physiotherapists, etc, are not allowed to know what treatment the patient has been given. Those that collect outcome parameters, such as MRI data and neurodevelopmental outcome, are also unaware of treatment allocation, meaning that blinding will be maintained during the full study-period of 18 months.
Primary Purpose: Treatment
Official Title: Darbepoetin for Ischemic Neonatal Stroke to Augment Regeneration
Actual Study Start Date : July 1, 2017
Estimated Primary Completion Date : December 31, 2024
Estimated Study Completion Date : June 1, 2025

Arm Intervention/treatment
Experimental: Darbepoetin
Darbepoetin alfa (Aranesp, Amgen)
Drug: Darbepoetin Alfa
Darbepoetin alfa (Aranesp, Amgen) 2 doses of 10 microgram/kg i.v.
Other Name: Aranesp

Placebo Comparator: Placebo
Drug: Saline
The placebo will consist of saline, containing 9.0 g of salt per liter (0.90%) i.v.
Other Name: Sodium Chloride

Primary Outcome Measures :
  1. Change in stroke tissue loss [ Time Frame: 6-8 weeks of age ]
    The 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 between the time of onset of the insult and 6-8 weeks of age. The primary endpoint will be estimated using advanced volumetric magnetic resonance (MRI) techniques, performed within one week after clinical presentation and at 6-8 weeks of age.

Secondary Outcome Measures :
  1. Reorganization of corticospinal connectivity [ Time Frame: 6-8 weeks of age ]
    To assess whether there are differences between darbepoetin and placebo treatment in Diffusion Tensor Imaging (DTI) parameters of selected regions of interest. DTI-MRI techniques are performed at 6-8 weeks of age.

  2. Neurodevelopment [ Time Frame: 18 months of age ]
    To assess cognitive and motor development at 18 months of age using the Bayley Scales of Infants and Toddler Development (BSITD)-III scores compare them between groups (darbepoetin vs placebo).

  3. Neurological assessment [ Time Frame: 18 months of age ]
    To assess neurological deficit and function using the Pediatric Stroke Outcome Measure (PSOM) and compare this score between groups (darbepoetin vs placebo). The PSOM is performed at 18 months of age.

  4. Development of Cerebral Palsy [ Time Frame: 18 months of age ]
    Development of Unilateral Spastic Cerebral Palsy (USCP) using the Gross Motor Function Classification system (GMFCS) and compare this between groups (darbepoetin vs placebo).
