简要总结
This study will assess safety and feasibility of bone marrow-derived allogeneic MSCs, administered by the nasal route, in neonates who suffered from PAIS.
详细描述
Perinatal arterial ischemic stroke (PAIS) is an important perinatal cause of long-lasting neurodevelopmental problems. Recent studies report an incidence of PAIS of 1 per 2300 full-term infants born alive. Adverse consequences of PAIS include hemiplegia, cognitive dysfunction, epilepsy and speech problems. In 50-75% of infants, neonatal stroke leads to abnormal neuromotor and -developmental outcome or epilepsy. The estimated annual mortality rate of neonatal stroke is 3.49/100,000 annually. Current treatment options for PAIS mainly focus on controlling convulsions and associated infections. There is no treatment available that leads to reduction of neonatal brain damage in this severely affected group of infants. This leads to life-long consequences of PAIS and forms a large burden for patients and society. The overall aim of this project is to meet this need by developing a cell based treatment strategy. Animal models of neonatal brain injury provide evidence for the feasibility and efficacy of intranasal mesenchymal stromal cell (MSC) application in the treatment of PAIS. Additionally, results from human trials with MSCs in the treatment of adult stroke or other pathologic conditions provide evidence that MSC treatment is safe. This project aims at making the first step towards clinical application of MSCs to treat PAIS. Successful completion of this project will provide the first evidence of the safety and feasibility of MSCs to treat brain damage in newborn infants. This study will assess safety and feasibility of bone marrow-derived allogeneic MSCs, administered by the nasal route, in neonates who suffered from PAIS.

研究组 & 干预措施
Mesenchymal Stem Cells
All (near-)term newborns ≥36 weeks of gestation with or without clinical symptoms of PAIS but with a magnetic resonance imaging (MRI) confirmed PAIS (in the Middle Cerebral Artery region) will be eligible for this study. Following written parental consent, 10 patients will be included in our study.
干预措施: Mesenchymal Stem Cells (Biological)
结局指标
主要结局
Number of Participants With Adverse Events Related to Intranasal MSC Treatment (Safety and Tolerability) in the Acute Setting.
时间窗: 24 hours after treatment
The primary objective is to determine if MSC treatment in neonates with PAIS is safe and tolerable in the acute setting. This will be measured by the number of Participants with treatment-related adverse events after MSC treatment.
次要结局
- Number of Participants With Adverse Events Related to Intranasal MSC Treatment (Safety and Tolerability) in the Subacute/Long-term Setting(3 months postnatal age)
