Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The objective of this trial is to validate the hypothesis that intranasal insulin improves development in children with Phelan-McDermid syndrome.;Secondary Objective: The secondary objective of this trial is to validate the hypothesis that intranasal insulin improves development in children with Phelan-McDermid syndrome.;Primary end point(s): The primary end point is developmental pace. Development is assessed by the Bayley-III-NL (Dutch version of the Bayley-III, Bayley, 2006) or WPPSI-III-NL (Dutch version of the WPPSI-III, Wechsler, 2009) dependent on the developmental age of the children. Both the Bayley-III and the WPPSI are individually administered tests that provide subtests and composite scores that represent general functioning. Developmental pace is calculated as the difference in developmental age equivalent between two assessments divided by the difference in calendar age in months at the time of these assessments (typically 6 months), resulting in a value for developmental age increase / month.;Timepoint(s) of evaluation of this end point: 6, 12, 18 months after initiation of the clinical trial phase | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The secondary end point is behaviour. Behaviour is assessed by the following questionnaires: Vineland screener, ESSEON, CBCL1,5-5, and Brief-P. To evaluate behaviour in several domains, raw scores are determined. ;Timepoint(s) of evaluation of this end point: 6, 12, 18 months after initiation of the clinical trial phase | — |
