Randomized open-label study comparing children aged 3 to 6 years with autism and normal cognitive development or mild cognitive impairment receiving the usual treatment plus intensive use of eGOLIAH (experimental group) with children receiving only the usual treatment (control group).

eGOLIAH (Gaming Open Library for Intervention in Autism at Home) is an accessible online platform for digital games inspired by the principles of the Early Start Denver Model (ESDM), one of the care programs validated in the management of young ASD.

The duration per patient will be one year. The exposure to e-GOLIAH for the experimental group will be done with the recommendation of intensive exposure to the game (5 sessions> ½ hour per week).

Clinical variables will be assessed at entry, 6 months and 1 year (end of study).

The EQ5D questionnaires will be collected by the supervising therapist during the follow-up visit and at the same time as the clinical variables.

In a context of increasing prevalence of Autism Spectrum Disorder (ASD) and the heterogeneity of children's profiles and abilities, early diagnosis is crucial in order to implement intensive, individualized, multidimensional therapeutic care and therefore more efficient. In the context of MICHELANGELO (FP7 European Research project), we developed a serious game called GOLIAH for Gaming Open Library for Intervention for Autism at Home. Using the first beta version as functional prototype, we showed that the demonstrator could be used at home with the help of parents in addition to usual care, during a clinical study including 25 participants. Also, Billeci and colleagues showed that, after training, children's improvement in joint attention tasks was correlated with changes in brain activity and connectivity. We then developed a new version e-GOLIAH to open the opportunity to conduct a large clinical study to assess the validity of the tool in terms of children's improvements. The goals of e-GOLIAH are to bring improvements in terms of ergonomics and accessibility to this initial prototype by finalizing the tool and distributing it to therapists, parents and children with ASD, via the Curapy.com web platform. e-GOLIAH provides, in free and open access, a platform for digital games inspired by the principles of ESDM (Early Start Denver Model) allowing intensive training to improve joint attention and imitation, two key skills for early social interaction and communication. It is a more natural, child-centered intervention method practiced at home and involving parents. This innovative solution takes the assessment and management of autism care out of the usual clinical environment. eGOLIAH (Gaming Open Library for Intervention in Autism at Home) is an accessible online platform for digital games that include ten different games with different level of complexity. A key principle is the collaboration between the child and his/her parent to proceed with the games making it interactive by nature, each participant having his own tablet.

The current study e-GOLIAH-ECO is a medico-economic study powered to recruit 150 children. It is a multisite randomized open-label study comparing children aged 3 to 6 years with autism and normal cognitive development or mild cognitive impairment receiving the usual treatment plus intensive use of eGOLIAH (experimental group) with children receiving only the usual treatment (control group).

The duration per patient will be one year. The exposure to e-GOLIAH for the experimental group will be done with the recommendation of intensive exposure to the game (5 sessions> ½ hour per week).

Clinical variables will be assessed at entry, 6 months and 1 year (end of study). The EQ5D (quality of life) questionnaires will be collected by the supervising therapist during the follow-up visit and at the same time as the clinical variables.

The main objective is to evaluate the 12-month cost-effectiveness of the management of children diagnosed with ASDs using the e-GOLIAH game used at home, compared to usual management.

Secondary objective includes:

(i) To evaluate the cost-effectiveness ratio of the management of patients with ASDs using e-GOLIAH compared to usual management at 12 months of follow-up.

(ii) To explore the remaining ASD-related annual burden of the cost of disease for the two groups studied.

(iii) To evaluate the consequences of the generalization of the management of children diagnosed with ASD using e-GOLIAH, compared to a usual management, from the point of view of the Health Insurance over a period of 3 years.

(iv) To evaluate the impact of the management of children diagnosed with ASD using the e-GOLIAH game used at home, compared to usual management, on the patient's quality of life and that of their responsible parent and the correlation between the two, on adaptive symptoms, on autistic symptoms, on social interactions, on parental stress, at 6 months and at 12 months.

(v) To assess compliance with OS by children and their caregivers. The following scales will be monitored: the EQ5D-3L for quality of life, the Vineland-II scale, the Child Autism Rating Scale (CARS), the Social Responsiveness Scale (SRS), the Parenting Stress Index. In addition the medico-economic data will be monitored from regular interview and social insurance data.
