Gedetailleerde beschrijving
Het doel van deze dubbelblinde fase II-studie is het bepalen van de werkzaamheid van van menselijk navelstrengweefsel afgeleide mesencymale stromale cellen (hCT-MSC), toegediend in twee verschillende doseringsstrategieën, bij kinderen met een autismespectrumstoornis (ASS).
Deze studie zal kinderen met ASS in de leeftijd van 4-11 jaar inschrijven. In aanmerking komende proefpersonen ondergaan neuropsychologische evaluatie, EEG-testen, eye-tracking, CVA-beoordelingen en infusie van onderzoeksproduct. Onderwerpen worden gerandomiseerd naar een van de twee studiearmen; 1) een enkelvoudige infusie van 6,0x106 cellen/kg bij baseline, gevolgd door een geblindeerde placebo-infusie na zes maanden, of 2) Placebo-infusie bij baseline, gevolgd door een intraveneuze dosis van 6x106 cellen/kg na zes maanden.
Het primaire eindpunt van deze studie is de verandering in sociale communicatieve vaardigheden vanaf de basislijn tot zes maanden. De mogelijke risico's die gepaard gaan met infusie van MSC's zijn onder meer een reactie op het product (uitslag, kortademigheid, piepende ademhaling, moeite met ademhalen, hypotensie, zwelling rond de mond, keel of ogen, tachycardie, diaforese), overdracht van infectie en HLA-sensibilisatie.

Change on the Average Socialization and Communication Subscale Standard Scores on the Vineland Behavior Scales (VABS-3)
Tijdsspanne: Baseline, 6 months
|
The primary outcome measure is the mean of the Socialization and Communication Subscale Standard Scores on the Vineland Adaptive Behavior Scales (VABS-3) from the Comprehensive Interview form.
The primary endpoint is the change in this outcome measure from baseline to six months before the second infusion.
A positive change in the scores indicates an improvement in socialization and communication.
A standard score of 100 is the mean with a standard deviation of 15 points.
A score of 100 should be understood as being similar to the typical population of the same age.
Scores greater than or equal to 86 are considered adequate or above adequate.
Domain scores less than or equal to 85 are considered moderately low to low and indicate the patient has a significant skill deficit when compared with similarly aged peers.

CGI-S (Clinical Global Impression - Severity of Illness) Overall Score
Tijdsspanne: 6 months
|
The CGI-S Overall Score is a 7-point scale that requires the clinician to rate the severity of the participant's overall functioning and symptoms of autism at the time of assessment, relative to the clinician's experience with participants who have the same diagnosis.
The clinician rates the severity of autism symptoms - 1, normal, no symptoms; 2, borderline level of symptoms; 3, mild symptoms; 4, moderate symptoms; 5, marked symptoms; 6, severe symptoms; or 7, extremely severe symptoms.
The higher ratings indicate greater severity of overall functioning impairment.

The symptoms are rated as: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse.
The lower scores indicate greater improvement.

Change in the Pediatric Quality of Life (PedsQL) Total Scale Score
Tijdsspanne: Baseline, 6 months
|
The PedsQL 4.0 Generic Core Scales is a 5-minute parent questionnaire that measures the child's functioning in the dimensions of physical, emotional, social, and school.
The items use a Likert rating scale from 0 (Never) to 4 (Almost Always).
This 0-4 scale is then transformed to 0=100, 1=75, 2=50, 3=25, and 4=0 for a reverse score.
The Total Scale Score is then computed as the sum of all the items over the number of items answered on all the Scales for a total score range of 0 to 100.
Higher scores indicate a better quality of life.
