E.5 End points |
E.5.1 | Primary end point(s) |
The Change in Drooling Impact Scale (DIS) between baseline and D84. The DIS scale is a questionnaire of 10 questions with a score of 100 points which is completed by the patient's entourage (family and/or caregivers). This scale has a good validity and sensitivity to changes in the context of the evaluation of the drooling in children with CP, with a score difference of 13.6 points considered as clinically relevant (Reid 2010).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The evaluation of the primary efficacy endpoint will be performed for the full analysis set (ITT) and for the mITT analysis set. The primary analysis set will be the full analysis set. All statistical tests will be two-sided and the significance level will be 5%. Mean difference in DIS between baseline and D84 (+/- 5 days) between the Sialanar and placebo group. A 13.6 points change in DIS Scale score will be considered as a clinically relevant change. |
|
E.5.2 | Secondary end point(s) |
Other efficacy endpoints: 2. Change in DIS Scale between baseline and D28. 3. Proportion of responders at D84 (a response is defined as a DIS improvement ≥ 13.6 points). 4. Proportion of responders at D28 (a response is defined as a DIS improvement ≥ 13.6 points). 5. Proportion of good responders at D84 (a good response is defined as a DIS improvement ≥ 28 points). 6. Changes in the number of used bibs or clothing over 7 days (Item 3 of the DIS) at D84 7. Changes in the number of used bibs or clothing over 7 days (Item 3 of the DIS) at D28
Quality of life endpoints: - Change in the DIS 10-point item 9 from baseline. “To what extent did your child’s drooling affect his or her life?” to D28 and D84. - Change in in the DIS 10-point item 10 from baseline. “To what extent did your child’s dribbling affect you and your family’s life?” to D28 and D84. - The change in DISABKIDS instrument from baseline to D84. Safety Endpoints: - Adverse events recorded from baseline to day 84, including: - all AE, - all AE with the exception of dose dependent expected AE related to titration, - all SAE. - AEs leading to discontinuation of study medication - all treatment-related AEs - all treatment-related AEs with the exception of dose dependent expected AE related to titration Adverse events will be collected at every visit from parent or carer and participant where possible. All adverse events will be recorded at every scheduled visit plus outside of visits as required.
Open- label study extension endpoints: - Changes in DIS Scale between baseline and D252 and between D84 and D252 in the previous ‘Sialanar®-arm’ patients. - Change in DIS Scale between D84 and D252 for patients previously taking placebo - Change in the DIS 10-point item 9. “To what extent did your child’s drooling affect his or her life?” between baseline and D252. - Change in the DIS 10-point item 10. “To what extent did your child’s dribbling affect you and your family’s life?” between baseline and D252. - Change in DISABKIDS instrument score between baseline and D252. - Adverse events recorded from D84 to D252
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Secondary efficacy endpoints assessments: proportion of responders at D84 and D28, changes in DIS at D28, proportion of good responders at D84, changes in bib/ clothes over 7 days at D84 and D28 . Patient-reported outcome assessments using general (DISABKIDS) and specific (DIS items 9 and 10) approaches will be analysed to determine if response to therapy and side effects of therapy are accompanied by measurable changes in the quality of life.
Safety will be evaluated by the incidence of AEs, severity and type of AEs.
