Data Protection

Infographic: Navigating Data Protection and Privacy

Updated: January 31, 2024

Operationalizing privacy is challenging, but there are clear steps you can take to devise an operational policy that supports your business goals. This infographic lays out the important decision points in a logical, step-wise flow.

A Review of Biopharma Sponsor Data Sharing Policies and Protection Methodologies (updated September 2023): This whitepaper updates CRDSA’s 2022 systematic review of data contributor policies and data protection methodologies. This update includes information published by 35 biopharma sponsors. Highlights include:

  • The review now covers 35 biopharma sponsors, a 20% increase from 2022.
  • The consistency of dataset- and documentation-sharing policy commitments establish a reference benchmark for all data contributing organizations.
  • Challenges remain in the areas of data transformation transparency and data protection methodology.

Technology and Innovation

Data Sharing Technology Assessment Framework

Updated: October 26, 2023
CRDSA’s Technology and Innovation Work Group has developed a data-sharing technology assessment framework to support stakeholders in their evaluation of technologies and approaches that advance their data-sharing initiatives, whether they are interested in technologies for external data sharing or support an organization’s internal data reuse. The framework is designed to assist stakeholders in determining the requirements and use cases important to their organization. The resulting assessment scores can be used to compare how well different technology approaches or project scopes meet organizational objectives. The Assessment Framework is now publicly available as an R Shiny application, with an accompanying introduction and guide.

Innovative Trial Design

FDA Draft External Controls Guidance

Updated: August 22, 2023

Innovative trial designs that make use of the totality of available evidence can reduce the burden on patients and meaningfully improve the drug development process. In February 2023, the FDA released for public comment: “Considerations for the Design and Conduct of Externally Controlled Trials for Drug and Biological Products” (Docket FDA-2022-D-2983).

The draft guidance received over 200 responses from industry sponsors, patient advocacy organizations, academic research institutions, non-profit consortia, and patients. In July, CRDSA convened a roundtable panel of experts to discuss issues raised by commenting organizations and explore ways to ensure the expanded use of alternative control trial designs in regulatory submissions. The August 2023 FDA Draft External Controls Guidance: Situation Analysis and Recommendations report summarizes the roundtable discussion, key regulatory challenges, and recommendations.

Secondary Use Standards

“Establishing a Basis for Secondary Use Standards in Clinical Trials”

Updated: March 8, 2023
This paper, published in Applied Clinical Trials, reports on CRDSA’s 2022 survey of biopharma and academic researchers. The paper discusses how common standards can accelerate the reuse of trial data, benefiting both data contributors and the research community. The results of the survey will inform the development of data contribution best practices.

JAMA Oncology: Heterogeneity and Utility of Pharmaceutical Company Sharing of Individual-Participant Data Packages

Date: October 5, 2023
In this original investigation, Dr. Ashley Hopkins (Flinders University) and colleagues, including Frank Rockhold (Duke CRI and CRDSA Board Director) and Aaron Mann (CRDSA), address the utility and completeness of individual-participant data (IPD) and the supporting documents provided from industry-sponsored clinical trials. The study includes IPD packages received from 70 of 91 eligible clinical oncology trials. (77%) for a planned meta-analysis. The analysis indicated substantial variability within the provided IPD packages regarding the completeness of key data variables and supporting documents. To improve the data sharing ecosystem, key areas for enhancement include (1) ensuring that clinical trials are eligible for IPD sharing, (2) making eligible IPD transparently accessible, and (3) ensuring that IPD packages meet a standard of utility and completeness.
