Yksityiskohtainen kuvaus
Tämän kaksoissokkoutetun vaiheen II tutkimuksen tarkoituksena on määrittää ihmisen napanuorakudoksesta peräisin olevien mesentsymaalisten stroomasolujen (hCT-MSC) tehokkuus kahdessa eri annostusstrategiassa lapsille, joilla on autismispektrihäiriö (ASD).
Tähän tutkimukseen otetaan 4–11-vuotiaita lapsia, joilla on ASD. Hyväksytyt koehenkilöt käyvät läpi neuropsykologisen arvioinnin, EEG-testin, katseen seurannan, CVA-arvioinnit ja tutkimustuotteen infuusion. Koehenkilöt satunnaistetaan toiseen kahdesta tutkimushaarasta; 1) yksittäinen infuusio 6,0 x 106 solua/kg lähtötilanteessa, jota seuraa sokkoutettu lumelääkeinfuusio kuuden kuukauden kuluttua tai 2) lumelääke-infuusio lähtötilanteessa, jota seuraa suonensisäinen annos 6 x 106 solua/kg kuuden kuukauden kuluttua.
Tämän tutkimuksen ensisijainen päätepiste on sosiaalisen kommunikaatiotaidon muutos lähtötasosta kuuteen kuukauteen. MSC-infuusion mahdollisia riskejä ovat reaktio tuotteeseen (ihottuma, hengenahdistus, hengityksen vinkuminen, hengitysvaikeudet, hypotensio, turvotus suun, kurkun tai silmien ympärillä, takykardia, hikoilu), infektion leviäminen ja HLA-herkistyminen.

Change on the Average Socialization and Communication Subscale Standard Scores on the Vineland Behavior Scales (VABS-3)
Aikaikkuna: 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
Aikaikkuna: 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.

Change in the Pediatric Quality of Life (PedsQL) Total Scale Score
Aikaikkuna: 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.
