The Clinical Research Data Sharing Alliance
Developing Collaborative Solutions

Established in 2021, the Clinical Research Data Sharing Alliance (CRDSA) is a multi-stakeholder consortium that serves the clinical data sharing ecosystem. Our members include biopharma companies, nonprofit data sharing platforms, academic institutions, and service and technology partners. This diverse and growing group of stakeholders comes together with the shared goal of accelerating the discovery and delivery of life-saving and life-changing therapies to patients by expanding the research value of the high-quality data collected through the clinical trial process.

CRDSA is governed by a Board of Directors, with representation evenly balanced between industry and non-profit/academic organizations. A Board-chartered Steering Committee, comprised of 20 senior-level member representatives, governs CRDSA’s Work Groups. The Steering Committee ensures that Work Group activities support CRDSA’s strategic objectives with actionable and achievable deliverables.

CRDSA creates a forum to:

  • Address challenges across the life sciences data sharing ecosystem

  • Ensure the integrity, quality, and usability of contributed data through common data standards and best practices

  • Advance a FAIR data environment to promote consistency, reuse and broad access

  • Drive policy change to support the data sharing ecosystem, facilitating broader access and research value

  • Advocate and promote the value and use of shared data across the stakeholder landscape

  • Develop new and innovative approaches to advance data sharing principles
