Cultural, geographical and ethical questions when looking to enroll pediatric patients in rare disease clinical trials

Parents' expectations regarding case management for rare diseases in Switzerland: mixed-method findings from an online survey

AIMS OF THE STUDY

This pilot study aims to enhance understanding by examining parents' specific views on the requirements, content and objectives of case management and advanced care coordination for children with rare diseases during childhood. The findings of this study are expected to offer valuable insights and recommendations for existing and future initiatives in clinical practice and research, with the goal of improving the comprehensive, child-centred and family-orientated approach to case management.

METHODS

This pilot study is part of an ongoing prospective study (SPACE), involving parents and families from various networks in Switzerland. Participants were parents recruited from the Children with Rare Diseases (KMSK) network consisting of families with children with rare diseases. The survey questionnaire covered demographic information; expectations and perceived need for case management; assessment of their quality of life and their child's suffering; and evaluation of interprofessional and interdisciplinary communication. Qualitative data from free-response answers were analysed using Mayring's content analysis and descriptive statistics were used to analyse quantitative data from Likert-scale questions.

RESULTS

The study included 108 respondent families from among the 775 in the KMSK, a 14% response rate. The age of their children ranged from 0.4 to 24 years (mean: 8) and their level of suffering in the past six months varied, with 31.5% indicating intense or very intense suffering. In terms of case management, 15.8% of families reported access while 32.4% expressed a need but did not have access to it. The study identified three categories of parental expectations regarding case management, emphasising the importance of interprofessional collaboration, effective communication and comprehensive support.

CONCLUSIONS

The findings shed light on the high need for case management support with a current undersupply in Switzerland and an association with reduced parental quality of life, highlighting the necessity for diverse support and assistance to effectively manage the challenges faced by families with children with rare diseases.

Pharmacovigilance for rare diseases: a bibliometrics and knowledge-map analysis based on web of science

OBJECTIVES

The aims of this paper is to search and explore publications in the field of pharmacovigilance for rare diseases and to visualize general information, research hotspots, frontiers and future trends in the field using the bibliometric tool CiteSpace to provide evidence-based evidence for scholars.

METHODS

We searched the Web of Science Core Collection (WoSCC) for studies related to pharmacovigilance for rare diseases, spanning January 1, 1997-October 25, 2022. CiteSpace software was utilized to discuss countries/regions, institutions, authors, journals, and keywords.

RESULTS

After screening, a total of 599 valid publications were included in this study, with a significant upward trend in the number of publications. These studies were from 68 countries/regions with the United States and the United Kingdom making the largest contributions to the field. 4,806 research scholars from 493 institutions conducted studies on pharmacovigilance for rare diseases. Harvard University and University of California were the top two productive institutions in the research field. He Dian of the Affiliated Hospital of Guizhou Medical University and Peter G.M. Mol of the University of Groningen, The Netherlands, were the two most prolific researchers. The Cochrane Database of Systematic Reviews and the New England Journal of Medicine were the journals with the highest number of articles and co-citation frequency respectively. Clinical trial, therapy and adverse event were the top three most cited keywords.

CONCLUSIONS

Based on keywords co-occurrence analysis, four research topics were identified: orphan drug clinical trials, postmarketing ADR surveillance for orphan drugs, rare diseases and orphan drug management, and diagnosis and treatment of rare diseases. Immune-related adverse reactions and benefit-risk assessment of enzyme replacement therapy were at the forefront of research in this field. Treatment outcomes, early diagnosis and natural history studies of rare diseases may become hotspots for future research.

Clinical trials in pediatric ALS: a TRICALS feasibility study

Background: Pediatric investigation plans (PIPs) describe how adult drugs can be studied in children. In 2015, PIPs for Amyotrophic Lateral Sclerosis (ALS) became mandatory for European marketing-authorization of adult treatments, unless a waiver is granted by the European Medicines Agency (EMA).

Objective: To assess the feasibility of clinical studies on the effect of therapy in children (<18 years) with ALS in Europe.

Methods: The EMA database was searched for submitted PIPs in ALS. A questionnaire was sent to 58 European ALS centers to collect the prevalence of pediatric ALS during the past ten years, the recruitment potential for future pediatric trials, and opinions of ALS experts concerning a waiver for ALS.

Results: Four PIPs were identified; two were waived and two are planned for the future. In total, 49 (84.5%) centers responded to the questionnaire. The diagnosis of 44,858 patients with ALS was reported by 46 sites; 39 of the patients had an onset < 18 years (prevalence of 0.008 cases per 100,000 or 0.087% of all diagnosed patients). The estimated recruitment potential (47 sites) was 26 pediatric patients within five years. A majority of ALS experts (75.5%) recommend a waiver should apply for ALS due to the low prevalence of pediatric ALS.

Conclusions: ALS with an onset before 18 years is extremely rare and may be a distinct entity from adult ALS. Conducting studies on the effect of disease-modifying therapy in pediatric ALS may involve lengthy recruitment periods, high costs, ethical/legal implications, challenges in trial design and limited information.

ERNICA Consensus Conference on the Management of Patients with Esophageal Atresia and Tracheoesophageal Fistula: Follow-up and Framework

INTRODUCTION

 Improvements in care of patients with esophageal atresia (EA) and tracheoesophageal fistula (TEF) have shifted the focus from mortality to morbidity and quality-of-life. Long-term follow-up is essential, but evidence is limited and standardized protocols are scarce. Nineteen representatives of the European Reference Network for Rare Inherited Congenital Anomalies (ERNICA) from nine European countries conducted a consensus conference on the surgical management of EA/TEF.

MATERIALS AND METHODS

 The conference was prepared by item generation (including items of surgical relevance from the European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN)-The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) guidelines on follow-up after EA repair), item prioritization, formulation of a final list containing the domains Follow-up and Framework, and literature review. Anonymous voting was conducted via an internet-based system. Consensus was defined as ≥75% of those voting with scores of 6 to 9.

RESULTS

 Twenty-five items were generated in the domain Follow-up of which 17 (68%) matched with corresponding ESPGHAN-NASPGHAN statements. Complete consensus (100%) was achieved on seven items (28%), such as the necessity of an interdisciplinary follow-up program. Consensus ≥75% was achieved on 18 items (72%), such as potential indications for fundoplication. There was an 82% concordance with the ESPGHAN-NASPGHAN recommendations. Four items were generated in the domain Framework, and complete consensus was achieved on all these items.

CONCLUSION

 Participants of the first ERNICA conference reached significant consensus on the follow-up of patients with EA/TEF who undergo primary anastomosis. Fundamental statements regarding centralization, multidisciplinary approach, and involvement of patient organizations were formulated. These consensus statements will provide the cornerstone for uniform treatment protocols and resultant optimized patient care.
