Considerations for development of an evidence dossier to support the use of mobile sensor technology for clinical outcome assessments in clinical trials.

BACKGROUND: Mobile sensors offer enormous potential for the collection of informative clinical endpoints in clinical trials to support regulatory decision making and product labelling. There are currently no specific guidelines on the information needed to enable regulators to review and accept proposed endpoints derived from mobile sensors for use in drug development trials. OBJECTIVE: The purpose of this working group report is to recommend the structure and content of an evidence dossier intended to support whether a clinical endpoint derived from mobile sensor data is fit-for-purpose for use in regulatory submissions for drug approvals. EVIDENCE DOSSIER: The structure and content of a dossier to provide evidence supporting the use of a sensor-derived clinical endpoint is described. Sections include clinical endpoint definition and positioning, the concept of interest, the context of use, clinical validation and interpretation, study implementation, and analytical validity with sensor performance verification in support of the selected sensor. CONCLUSIONS: In the absence of definitive regulatory guidance, this report provides a considered approach to compiling a comprehensive body of evidence to justify acceptance of mobile sensors for support of new drug applications.

Methodological recommendations for comparative research on the treatment of chronic wounds.

OBJECTIVE: To provide specific recommendations to product developers and clinical researchers on the design of comparative effectiveness studies for the treatment of chronic wounds, specifically those pertaining to arterial and venous-disease related ulcers, diabetic foot ulcers, pressure ulcers and burn wounds. METHOD: The recommendations were developed based on a process defined by the Center for Medical Technology Policy (CMTP). After selecting the subject area, semi-structured phone interviews were conducted by one of the authors (SSS) with representatives of payers, manufacturers, clinicians, clinician/researchers and patient advocates. Next, a broad range of stakeholders participated in a meeting convened by CMTP to determine their needs. A technical working group comprising key stakeholders then participated in clarifying recommendations developed by CMTP staff and adding important considerations for their implementation. The resulting draft document was finalised based on public and solicited comment from individual manufacturers; a consortium of product developers and manufacturers; and an alliance of physicians, providers, manufacturers and patient organisations. This article is a summary of the full effectiveness guidance document. RESULTS: To address the needs of patients, clinicians, guideline developers, payers and other post-regulatory decision makers, this work makes ten recommendations to guide comparative effectiveness research for chronic wound care. These recommendations fall into four categories: study design, population, comparators and outcomes. CONCLUSION: This paper suggests that using the recommendations outlined to conduct comparative effectiveness research on treatments for chronic wound therapies would facilitate trials that provide patients, clinicians, and payers with the information they need to make optimal treatment decisions. These recommendations focus on design changes that would have the largest impact in improving the usability of the results by decision makers and provide specific guidance on the design of prospective studies intended to inform decision making by patients, clinicians and payers.
