E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Test the hypothesis that antibiotic treatment of GAS colonisation compared to placebo is associated with a larger reduction of tic and associated neuropsychiatric symptoms in the short-term (1 month) in patients with a tic disorder colonised by GAS. |
De hypothese testen dat antibiotica behandeling van GAS colonisatie vergeleken met placebo samen hangt met een grotere reductie van tic en aanverwante neuropsychiatrische symptomen op de korte termijn (1 maand) in patiënten met een tic stoornis met een GAS colonisatie. |
|
E.2.2 | Secondary objectives of the trial |
Test the hypothesis that antibiotic treatment of GAS colonisation is superior to placebo in the long-term (1 year) reduction of tic and associated neuropsychiatric symptoms in patients with a tic disorder colonized by GAS. Investigate the influence of possible moderators on treatment outcome. Investigate the effects of antibiotic treatment on patient’s immune responses to GAS antigens. |
De hypothese testen dat antibiotica behandeling van GAS colonisatie vergeleken met placebo superieur is op de lange termijn (1 jaar) en samen hangt met een grotere reductie van tic en aanverwante neuropsychiatrische symptomen in patiënten met een tic stoornis met een GAS colonisatie. De invloed van mogelijke moderatoren op behandelings uitkomsten onderzoeken. De invloed onderzoeken van de effecten van antibiotica behandeling op de immuun responsen op GAS antigenen. |

E.4 | Principal exclusion criteria |
The participant may not enter the study if ANY of the following apply: • Children and/or parents are unable to understand and comply with protocol • Any antibiotic treatment for any reason during the last month before enrolment in the trial. • Clinical manifestations of pharyngitis or other streptococcal infections at moment of enrolment in the trial. • Known or suspected hypersensitivity to penicillin or other β-lactam antibacterials, a history of amoxicillin-clavulanate-associated cholestatic jaundice or hepatic dysfunction. • Known and/or suspected renal or hepatic impairment (due to the potential for drug-related toxicity in patients with such a condition). • Scheduled elective surgery or other procedures requiring general anaesthesia during the study. • Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant’s ability to participate in the study. Participants who have participated in another research study involving an investigational product in the past 12 weeks |
De deelnemer mag niet aan de studie deelnemen indien een van de volgende dingen van toepassing is: Kinderen en/of ouders kunnen het studieprotocol niet begrijpen en zich er niet aan houden. • Antibiotica behandeling gedurende de laatste maanden voor deelname aan de studie • Klinische manifestaties van pharyngitis of andere streptokokken infecties op het moment van deelname in de studie • Bekende of verdachte hypergevoeligheid voor penicilline of andere β-lactam antibacterien, een geschiedenis van Amoxicilline-clavulanate- gerelateerde cholestatische gewrichts of hepatische disfunctie
• Geplande electieve chirurgie of andere procedures die algemene anaesthesie behoeven • Elke andere significante ziekte of stoornis die, in de ogen van de onderzoeker, die voor de deelnemer een risico vormen door deelname in deze studie, of die de resultaten van deze studie beïnvloeden, of de mogelijkheid van deelname in de studie. • Deelnemers die aan ander onderzoek in de afgelopen 12 weken hebben deelgenomen en waarbij een investigational product is gebruikt. |
