E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluate the effectiveness of bumetanide treatment on the intensity of young autistic disorders with known etiology, as measured by changes in the score CARS (Childhood Autism Rating Scale) between D0 (inclusion) and D99 (after 3 first months of treatment). |
Evaluer l’efficacité d’un traitement par bumétanide sur l’intensité des troubles de jeunes autistes avec une étiologie connue, mesurée par l’évolution du score du CARS (Childhood Autism Rating Scale ou échelle d'évaluation de l'autisme infantile) entre J0 (inclusion) et J99 (après les 3 premiers mois de traitement). |
|
E.2.2 | Secondary objectives of the trial |
- Describe the evolution of the CARS score between 0 and D99, D99 and D190 (3 months + 3 months) in the etiology of autism. - Determine the safety profile of the experimental treatment |
- Décrire l’évolution du score de CARS entre J0 et J99, J99 et J190 (3 mois + 3 mois) selon l’étiologie de l’autisme. - Déterminer le profil de sécurité du traitement expérimental |
|
E.2.3 | Trial contains a sub-study | No |

E.5 End points |
E.5.1 | Primary end point(s) |
The evolution of the result of the CARS (evaluation scale of the intensity of autism in child autism) between day 0 and day 99. |
Différence d’évolution du score CARS (échelle d’évaluation de l’intensité de l’autisme infantile) entre J0 et J99 entre les deux groupes de randomisation. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
1) CARS between D0 and D99 and between D99 and D190 which will be describe by etiology. 2) Analysis of adverse events which happened during the study (comparison of the two groups between D0 and D99, and analysis of the adverse events that occurred with subjects taking the Bumetanide between D0 and D190). The adverse events will be of a clinical and biological nature.
|
1.Comparaison de l’évolution du score de CARS entre J0 et J99, et J99 et J190 pour chaque sous-groupe d’étiologie de l’autisme. 2.Analyse des évènements indésirables (EI) survenus au cours de l’étude (comparaison entre les 2 bras entre J0 et J99, et analyse des évènements indésirables survenus sous Bumétanide entre J0 et J190). Les EI considérés seront de nature clinique et biologique.
