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.
Autism Spectrum Disorders (ASD) are heterogeneous neuro-developed disorders. Autism is the most common disorder of the diseases characterized by dysfunctions in response to social interaction and communication, as well as the presence of repetitive and stereotyped behaviors. Recent reports of a sharp increase in the number of children with autism. The exact etiology of autism remains unclear. Compliance, the definition of effective treatments for autism is particularly difficult.
Although it has been understood, it can be a question of immune dysregulation. Examination of the inflammatory cytokines, dysfunction of the immune system and the immune system. 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. Our study suggest that infusion of cord blood mononuclear cells will affect Autism.
This protocol was developed on the basis of the results of the previously approved protocol of the center NCT03786744 (Transfusion of allogeneic cord blood samples in patients with autism spectrum disorders), which showed high efficiency in the rehabilitation of patients. The present protocol is intended for revealing the dependence of the clinical effect on the degree of tissue compatibility of umbilical cord blood samples and the recipient.

| ASD CB-MNC infusion low level HLA compatibility. | Biological | 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. |

| 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) |

| Evaluation of the survival of donor cells in the host body without immune responses | Evaluation of the survival of donor cells in the host body to determine the safety and duration of the cellular component. To do this, before the first injection of the cells, a sample of the patient's blood and a donor cord blood sample will be taken. 6 months after the first injection of the cells, immediately before the second injection, the patient's blood will be re-taken to conduct a study on chimerism. The obtained data will allow assessing the survival degree of donor material. The definition of chimerism is carried out by fragment analysis. For analysis, blood samples of the biomaterial will be collected from the patient before the cells are injected and 6 months after the injection. |

This is prospective, non-randomized (open-label) with control group study. In total, the study will involve 150 patients in three groups. The first and second groups will receive transfusions of umbilical cord blood hematopoietic cells, with varying degrees of selection for the genes of the HLA system. The third group will be the control group. In the control group, 50 patients with similar pathology will be examined, comparable in age, sex and degree of disorder of the type of "para-copies" against the background of standard therapy.

| The correlation of the concentration of CD34+ cells in the cord blood sample and the treatment effectiveness degree | CD34+ cells are precursors of hematopoiesis and endothelium. Studies show that CD34+ cells, when injected into an ischemic lesion zone, exert protective properties on the affected cells, stimulate angiogenesis, and are involved in reducing inflammatory reactions. In this study, we plan to find a correlation between the concentration of the introduction of CD34+ cells and treatment effectiveness. The assessment of a cord blood sample will be carried out on a flow cytometer immediately before the injection of the cells or in the next 12 hours. | At 1, at 6 months (At first and second infusion) |
