Overview

The growing availability of real-world data (RWD) creates opportunities not only for innovation in evidence generation, but also for improving the efficiency and potential success rates of more-traditional clinical trials. To varying degrees, sponsors are now regularly using RWD to make data-driven decisions about trial feasibility, based on assessment of planned eligibility criteria. And increasingly, RWD are being used to support targeted, timely, and personalized outreach that may improve the efficiency and effectiveness of the recruitment process.

The recommendations, resources, and case studies in this document provide actionable tools to support researchers in implementing emerging best practices, including resources for:

  • Determining whether RWD are fit for purpose with respect to study planning and recruitment.
  • Optimizing the use of RWD for study planning and recruitment by engaging cross-functional teams and building out organizational systems and processes.
  • Understanding patient and site needs to develop successful and patient-centric approaches to RWD-supported recruitment.

Researchers can use this comprehensive set of work to apply RWD in a way that enhances eligibility criteria and recruitment, potentially resulting in increased efficiency, shorter timelines, and better patient access to research efforts.

Thank you to the experts and key stakeholders from across the clinical trials ecosystem who helped create this set of recommendations and resources, including all project team leaders and members, Expert Meeting members, Recommendations Advisory Committee members, and many others.

Introduction

Focusing primarily on the use of electronic health record (EHR) and insurance claims data for US-based studies of medical products, these recommendations identify considerations that are unique to, or especially important for, the use of RWD in planning eligibility criteria and recruitment. The recommendations can be used to support in-house curation and analysis of RWD sets, as well as to enhance interactions with data partners and technology providers.

We suggest using these recommendations as part of a broader Quality by Design process that focuses effort on activities that are essential to the credibility of the study outcomes, and that involves the broad range of stakeholders in protocol development and discussions around study quality. CTTI believes that increasing use of RWD from early in study planning will not only enhance trial feasibility and recruitment, but also support enrollment of patients that better reflect the populations most likely to use medical products, in alignment with emphasis in the FDA Reauthorization Act of 2017 (FDARA)1 and recent draft and final guidance documents.

DEFINITIONS

Real-World Data (RWD) are data relating to patient health status and/or the delivery of health care routinely collected by a variety of sources.

Real-World Evidence (RWE) is the clinical evidence about the usage and potential benefits or risks of a medical product derived from analysis of RWD.

Recommendations

SECTION I: General Principles for Using RWD

The recommendations below apply both to designing eligibility criteria that enhance the feasibility of recruitment, and to supporting recruitment processes by enhancing patient and site identification. See also specific considerations for each usage in Sections II and III, respectively.

Claims vs. Electronic Health Record (EHR) Data for Planning Eligibility Criteria and Recruitment

These recommendations focus on EHR and claims data, both of which have been successfully used to help plan eligibility criteria and support recruitment. The table below is a starting point, only, for understanding the advantages and disadvantages these two sources of RWD tend to have. The specific advantages and disadvantages of EHR and claims data (and their international equivalents) will vary from one data source to another.

While this document focuses on EHR and claims data, the same considerations can generally be applied to other sources of RWD (e.g., product and disease registries) that can also be highly appropriate for planning eligibility criteria and supporting recruitment. In many cases, it may be valuable to use several RWD sources side-by-side. In working with RWD, it is important to engage individuals knowledgeable about the specific data sources being used.

SECTION II: Using RWD to Plan Feasible Eligibility Criteria

This section provides specific considerations for using RWD to help plan eligibility criteria that fully consider the feasibility of successfully recruiting for the clinical trial.

SECTION III: Using RWD to Support Recruitment

This section provides recommendations for using RWD to support clinical trial recruitment. Though limited, evidence suggests that RWD supported recruitment strategies—such as direct email and letter campaigns to patients identified through claims data, and EHR-supported discussions at the point of care—have the potential to increase recruitment effectiveness (number of relevant patients identified) and efficiency (faster recruitment) for many trials.

SECTION IV: Enhancing RWD Capabilities for the Research Enterprise

To maximize the opportunities afforded by RWD to improve the efficiency and potential success rates of clinical trials, CTTI recommends continued, multi-stakeholder discussion, research, and identification of best practices. Specifically, we recommend addressing the following:

The recommendations in this document should be used in conjunction with the following related CTTI recommendations:

Quality by Design in Clinical Trials

  • When using real-world data to help design eligibility criteria and enhance recruitment, it is important to do so within the broader context of overall study design and conduct. CTTI recommends following a Quality by Design (QbD) approach that engages the broad range of stakeholders and focuses resources on the errors that matter to decision-making.
