Brief Summary
Autism is one of those disorders in Autism spectrum disorders (ASD), which characterized by social interaction abnormalities, impaired verbal and non-verbal communication, and repetitive, obsessive behavior, while the therapeutic effect of current treatments remains limited progress. The possible reason for ASD is neural hypoperfusion and immune dysregulation. The Human Umbilical Cord Blood Mononuclear Cells (hUCB-MNCs) have been shown to have the ability to modulate the immune response and enhance angiogenesis, suggesting the novel and promising therapeutic strategy. In this study, the safety and efficacy of hUCB-MNCs infusion will be evaluated in patients with Autism with regarding to HLA compatibility.

Outcome Measures
Primary Outcomes (3)
Number of participants with non-serious and serious adverse events.
Safety assessment. Adverse events rate will be assessed in all patients.
baseline, change from baseline at 12 month
The Childhood Autism Rating Scale (CARS2).
Rating for behavior, characteristics, and abilities against the expected developmental growth. Will be assessed fifteen items, including: relationship to people; imitation; emotional response; body; object use; adaptation to change; visual response; listening response; taste-smell-touch response and use; fear and nervousness; verbal communication; non-verbal communication; activity level; level and consistency of intellectual response; general impressions. Total score will be assessed. Scores range form 15 to 60 with 30 being the cutoff rate for a diagnosis of mild autism. Scores 30-37 indicate mild to moderate autism, while scores between 38 and 60 are characterized as severe autism.
baseline, change from baseline at 6,12 month
Autism Treatment Evaluation Checklist (ATEC).
Will be assessed: I. Speech/Language Communication (14 items); II. Sociability (20 items); III. Sensory/ Cognitive Awareness (18 items); and IV. Health/Physical/Behavior (25 items).
baseline, change from baseline every month (total 12 evaluations)
Secondary Outcomes (4)
Evaluation of the survival of donor cells in the host body without immune responses
baseline, change from baseline at 6 month
The correlation of the concentration of T-regulatory cells (CD4/CD25/FoxP3) in the sample of umbilical cord blood and the treatment effectiveness degree
At 1, at 6 months (At first and second infusion)
The correlation of the concentration of T-regulatory cells (CD4/CD25/FoxP3) in the patient depending on the severity of the disease.
At 1, at 6 months (At first and second infusion)
The correlation of the concentration of CD34+ cells in the cord blood sample and the treatment effectiveness degree
At 1, at 6 months (At first and second infusion)
Study Arms (3)
Group 1 Low HLA compatibility
EXPERIMENTALASD CB-MNC infusion from different donors and standard therapy. CBU with 3 or less HLA compatibility degree in A, B, DRB1 loci will be used.
Group 2 High HLA compatibility
EXPERIMENTALASD CB-MNC infusion from different donors and standard therapy. CBU with 3 or more HLA compatibility degree in A, B, DRB1 loci will be used.
Group 3 Control
OTHERPatients with standard therapy as a control group.
Interventions
CB-MNC infusion from different donors. One dose consists of 2-15х10\^7 cells per 1 kg of patient weight for each infusion. The protocol includes 2 infusions with an interval of 6-x months. HLA compatibility of the cord blood is 3 or fewer by A, B, DRB1 loci.
CB-MNC infusion from different donors. One dose consists of 2-15х10\^7 cells per 1 kg of patient weight for each infusion. The protocol includes 2 infusions with an interval of 6-x months. HLA compatibility of the cord blood is 4 or more by A, B, DRB1 loci.
The standard therapy can include drugs, special psychology training etc.
Eligibility Criteria
