Purpose: Teduglutide, a glucagon-like peptide-2 analog, has demonstrated efficacy in reducing parenteral support (PS) among patients with short bowel syndrome with intestinal failure (SBS-IF). This study aims to identify a subpopulation of SBS-IF patients for whom teduglutide has an especially pronounced effect.Patients and methods: Data were from a 24-week, Phase III trial (Study of Teduglutide Effectiveness in Parenteral Nutrition-Dependent SBS Subjects; NCT00798967) that randomized SBS-IF patients with PS dependency to receive teduglutide (n=43) or placebo (n=43). Two prediction models (1 for each arm) were developed for response, defined as 20% reduction in weekly PS at Weeks 20 and 24. Potential predictors included demographics, disease characteristics, and concomitant medications. Patients were then ranked based on the effect score, an individualized predicted response rate difference with teduglutide versus placebo. A subpopulation of patients with a pronounced benefit from teduglutide versus placebo was identified. Baseline characteristics and clinical outcomes were compared between patients included versus those not included in the subpopulation.Results: Six predictors of response to teduglutide were selected: older age, volvulus as the cause of major intestinal resection, baseline PS volume >6 L per week, longer time since start of PS dependency, absence of ileocecal valve, and lower percentage of colon remaining. Higher percentage of colon remaining and volvulus were the selected predictors for response to placebo. A subpopulation of patients more likely to respond to teduglutide was identified as those with the top 60% effect scores. The difference in response rate between teduglutide and placebo was 62% in the subpopulation, which was substantially higher than the difference of 33% in the overall population. Mean PS day reduction was also significantly higher for teduglutide compared to placebo in the subpopulation.Conclusion

Factors including barriers to accessing care, dissatisfaction with support services, and lack of caregiver resources may contribute to this.Objectives: To report caregivers’ experiences of ADHD diagnosis, behavioral therapy (BT), and supportive care for children/adolescents with ADHD.Methods: The Caregiver Perspective on Pediatric ADHD (CAPPA) survey included caregivers of children/adolescents (6–17 years) from ten European countries who were currently receiving/had received ADHD pharmacotherapy in the previous 6 months. Caregivers reported experiences of obtaining an ADHD diagnosis, access to BT, availability of caregiver resources, and level of health care/school support. Pan-EU and country-specific descriptive statistics are reported; responses were compared across countries.Results: Of 3,616 caregivers, 66% were female. Mean age of children/adolescents was 11.5 years; 80% were male. Mean time from the first doctor visit to diagnosis was 10.8 (95% confidence interval 10.2, 11.3) months; 31% of caregivers reported the greatest degrees of difficulty in obtaining an ADHD diagnosis; 44% of children/adolescents did not receive BT. Forty-seven percent of caregivers reported that sufficient resources were av

Objective: To analyze caregiver burden across the concepts of work, social/family life, and parental worry/stress, in relation to selected contributing factors. Methods: The online Caregiver Perspective on Pediatric ADHD survey was fielded in ten European countries. Analysis included children/adolescents (6–17 years) who were receiving/had received ADHD pharmacotherapy in the previous 6 months. Caregivers recorded their child’s/adolescent’s symptoms “on”/“off” medication (ie, when the caregiver reported that the child/adolescent forgot/chose not to take medication, before the onset of medication effect, or medication worn off). Effects of ADHD severity, comorbidities, and medication adherence on each burden outcome were assessed (multiple regression models). Results: In total, 2,326 caregivers were included (children/adolescents’ mean age: 11.5 years, 80% male). Caregivers reported missed/altered work, avoiding social activity, increased parental worry/stress, and strain on family life, despite using ADHD pharmacotherapy. Child/adolescent comorbidities and ADHD severity were significantly related to all burden concepts measured; the stronge

CAPPA included caregiver assessments of global medication satisfaction, global symptom control, and satisfaction with ADHD medication attributes. Overall, 2,326 caregiver responses indicated that their child or adolescent was currently receiving ADHD medication and completed the “off medication” assessment required for inclusion in the present analyses. Responses to the single-item global medication satisfaction question indicated that 88% were satisfied (moderately satisfied to very satisfied) with current medication and 18% were “very satisfied” on the single-item question. Responses to the single-item global symptom control question indicated that 47% and 19% of caregivers considered their child or adolescent’s symptoms to be “controlled” or “very well controlled”, respectively. Significant variations in response to the questions of medication satisfaction and symptom control were observed between countries. The correlation between the global medication satisfaction and global symptom control questions was 0.677
