E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to examine the efficacy of riluzole, a modulator of the glutamate /GABA balance, for treatment of psychotic symptoms and cognitive impairment in 22q11.2DS patients. |
Het doel van deze studie is om de werkzaamheid te onderzoeken van riluzol, een glutamaat / GABA modulator, voor de behandeling van psychotische symptomen en cognitieve stoornissen bij 22q11.2DS-patiënten. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective is to examine effects of riluzole on the glutamate/GABA-balance in order to increase insight in the neurobiological underpinnings of these symptoms. |
Het secundaire doel is om de effecten van riluzol op de glutamaat / GABA-balans in de hersenen te onderzoeken om meer inzicht te krijgen in de neurobiologische mechanisme die ten grondslag liggen aan deze symptomen. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Confirmed diagnosis of 22q11.2 deletion syndrome established by FISH, microarray or MLPA analysis. • 16 year or older of age and mentally competent (determined by an experienced physician) to give informed consent. • 16 years, incompetent to provide written informed consent. In these cases consent will be obtained from the legal representative of the subject. • Presence of psychotic and/or cognitive symptoms (defined as a score of ≥4, moderately ill, on the Clinical Global Impression-Schizophrenia Scale (CGI-SCH)). |
Bevestigde 22q11.2 deletie syndroom diagnose middels FISH, microarray of MLPA. • 16 jaar of ouder en wilsbekwaam ter zake om informed consent te geven.
