CDISC USDM Protocol Exchange

Explore structured clinical trial protocols

Access and learn from real-world protocol data — built for reuse, automation, and interoperability.

Built on the CDISC USDM standard

Why structured protocols matter

Digital protocols power faster, more automated trials

Digital protocols are key to faster, more efficient and more automated clinical trials.

Improve design

Reduce ambiguity and improve protocol quality from the first draft.

Streamline execution

Enable faster downstream activities with machine-readable definitions.

Remove friction

Eliminate manual rework across systems and organizations.

What this is

A shared repository of structured CDISC USDM protocols

Protocol Explorer provides access to a shared repository of structured, USDM-based clinical trial protocols. Anyone can browse and learn from the available protocols. Users who want to add and manage their own USDM-formatted protocols can create an account and contribute to the repository.
