ASC - Autism Study

Study Purpose


  • - Autism Pilot Study is a single center randomized open dose titrating phase I clinical intervention pilot trial with the aim of investigating safety and treatment effect of an allogeneic adipose tissue derived mesenchymal stromal cell product (C2C_ASC) in children with autism spectrum disorder (ASD) and gastrointestinal symptoms.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 6 Years - 14 Years
Gender All

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details


  • - Autism Pilot Study will be performed at the Child and Adolescent Psychiatry, Aalborg University Hospital, Denmark.
10 children aged 6-14 years with ASD and gastrointestinal symptoms will be enrolled through the Child and Adolescent Psychiatry, Psychiatry Clinic South, Aalborg University Hospital, Denmark. The participants will randomly be divied into two treatment groups: 1. participant 1-5 will be treated with 1 x 1000000 C2C_ASCs/kg body weight. 2. participant 6-10 will be treated with 2 x 1000000 C2C_ASCs/kg body weight. C2C_ASC treatment: The C2C_ASCs product will be diluted in 50 ml isotonic saline and infused in an arm vein within 15 min. In both groups there will for each participant be a week observation for SAE's related to the cell treatment before the next participant will be treated, if no SAE's have been detected. The investigators hypothesize that the connection between gastrointestinal symptoms/leaky gut syndrome, increase local gastrointestinal and systemic elevated immunological and inflammatory activity, bacterial toxins in the blood and symptoms of ASD in children with symptoms of leaky gut syndrome can be reduced or normalized by modulating the immunological activity and inflammation by treatment with mesenchymal stromal cells.

Drug: - Adipose tissue derived mesenchymal stromal/stem cells (Cell2Cure®)

The Investigational Product is a C2C_ASC cell product (Cell2Cure®, Cell2Cure Aps, Denmark). C2C_ASC is an advanced therapy investigational medicinal product (ATIMP) manufactured from abdominal adipose tissue derived mesenchymal stromal cells (ASC) from healthy donors. C2C_ASC is aseptically procured and manufactured according to tissue law and GMP by Cell2Cure ApS or Cardiology Stem Cell Center, Rigshospitalet, Copenhagen, Denmark, using manual isolation of cells from abdominal fat tissue, xeno-free cell expansion in automated closed bioreactor systems and cryopreservation of the final product. The active substance is the in vitro expanded ASCs. The final product, C2C_ASC, is provided as a cryopreserved suspension of 50 million ASCs per ml with a total volume of 1,3 ml per vial. The excipient is CryoStor10 (Biolife Solutions), holding 10% DMSO.
