Barriers to and facilitators of paediatric medical device innovation: a scoping review protocol.

INTRODUCTION: The development of paediatric medical devices continues to lag adult medical devices and contributes to issues of inequity, safety, quality and patient outcomes. New legislation and funding mechanisms have been introduced over the past two decades, but the gap remains. Clinical trials have been identified as a pain point, but components of effective clinical research infrastructure are poorly understood. As part of a multimodal research strategy, the Pediatric Device Consortia (PDC) will conduct a scoping review to better understand infrastructural barriers to and facilitators of paediatric medical device clinical research identified in the health sciences literature. METHODS AND ANALYSIS: The following databases will be included for this review: Medline, Embase, Cochrane CENTRAL, Web of Science and IEEE Xplore. Additional grey literature will be sought out through Google Scholar and reviewing the citations of included studies. Included studies will discuss medical devices according to the U.S. Food and Drug Administration classification, focus on the paediatric population (ages 0-21 years) and involve human premarket or postmarket research. All study types that were published in 2007-present in English, Spanish, French or Italian will be included. Using Covidence web-based software, two independent reviewers will screen the resulting titles, abstracts and the full text of potential studies. Conflicts will be resolved by the primary investigator during both phases. REDCap will be used for quantitative and qualitative data charting, generating data tables and narrative synthesis. ETHICS AND DISSEMINATION: This research did not require research ethics board consideration as it does not involve human participants and all data will be collected from published literature. We will share our findings through peer-reviewed manuscripts, clinical and research conference presentations and professional networks available to the PDC.

FDA's pediatric device consortia: national program fosters pediatric medical device development.

OBJECTIVES: This article reports on the progress made in addressing pediatric medical device needs through the establishment of the Pediatric Device Consortia Grant Program. Pediatric practitioners should be aware of both the imperative for well-studied devices for children and the existence of recently created resources to help foster the development of such products. METHODS: This article discusses some of the challenges associated with pediatric device development and describes the implementation of section 305 of the Pediatric Medical Device Safety and Improvement Act of 2007. This statute called for the creation of nonprofit consortia to facilitate the development, production, and distribution of pediatric medical devices. RESULTS: A summary of the accomplishments of the pediatric device consortia is presented. Eleven million dollars have been awarded to 5 consortia since 2009. As of July 2012, they have collectively assisted in the development of 219 pediatric device ideas. The consortia provide innovators with both mentorship and services to help advance proposed pediatric device projects, including assistance with prototyping, identification of potential funding sources, preclinical and clinical trial design, and introductions to potential manufacturers. CONCLUSIONS: Currently, 5 federally funded pediatric device consortia exist to help advance the development of potential pediatric devices. These consortia serve as a national resource for those with ideas for medical devices that may advance the health and well-being of children.

Pediatric cardiovascular safety: challenges in drug and device development and clinical application.

Development of pediatric medications and devices is complicated by differences in pediatric physiology and pathophysiology (both compared with adults and within the pediatric age range), small patient populations, and practical and ethical challenges to designing clinical trials. This article summarizes the discussions that occurred at a Cardiac Safety Research Consortium-sponsored Think Tank convened on December 10, 2010, where members from academia, industry, and regulatory agencies discussed important issues regarding pediatric cardiovascular safety of medications and cardiovascular devices. Pediatric drug and device development may use adult data but often requires additional preclinical and clinical testing to characterize effects on cardiac function and development. Challenges in preclinical trials include identifying appropriate animal models, clinically relevant efficacy end points, and methods to monitor cardiovascular safety. Pediatric clinical trials have different ethical concerns from adult trials, including consideration of the subjects' families. Clinical trial design in pediatrics should assess risks and benefits as well as incorporate input from families. Postmarketing surveillance, mandated by federal law, plays an important role in both drug and device safety assessment and becomes crucial in the pediatric population because of the limitations of premarketing pediatric studies. Solutions for this wide array of issues will require collaboration between academia, industry, and government as well as creativity in pediatric study design. Formation of various epidemiologic tools including registries to describe outcomes of pediatric cardiac disease and its treatment as well as cardiac effects of noncardiovascular medications, should inform preclinical and clinical development and improve benefit-risk assessments for the patients. The discussions in this article summarize areas of emerging consensus and other areas in which consensus remains elusive and provide suggestions for additional research to further our knowledge and understanding of this topic.

What the Orphan Drug Act has done lately for children with rare diseases: a 10-year analysis.

OBJECTIVES: The 1983 US Orphan Drug Act (ODA) provided incentives to stimulate treatment product development for patients with rare disease. This article highlights a decade of ODA contributions to this goal for children with RDs. METHODS: An internal US Food and Drug Administration database was the information source for orphan designations, marketing approvals, and prevalence numbers for 2000 to 2009. Product categorization was based on the disease age of onset for which they received designation. Category 1 products were for diseases with onset exclusively in Childhood; Category 2 products were for diseases with onset at any age; and Category 3 products were for diseases with adult onset only. Disease prevalence distributions were analyzed by using population intervals of 20 000. RESULTS: From 2000 to 2009, 1138 orphan drugs were designated and 148 received marketing approval, of which 38 (26%) were for pediatric diseases. The proportion of approvals for pediatric products increased from 17.5% (10 of 57) in the first half of the decade, to 30.8% (28 of 91) in the second. More products received designation and marketing approval for pediatric diseases with prevalence numbers fewer than 20 000 than for any other prevalence subgroup. The median disease prevalence for all pediatric orphan designations that received marketing approval was 8972. Among the pediatric orphan drug approvals categorized by therapeutic class, the endocrine/metabolic drugs had the largest representation (39%). CONCLUSIONS: The ODA incentives have led to increased product availability for RDs overall, with an increasing number of marketing approvals for children this past decade.
