Guide · Data ownershipUpdated September 29, 2026

Your trial data should leave with you

The sponsor owns the trial data, but ownership means little if the data is hard to get out. Portability means complete exports in open formats, with the audit trail, signatures and study design, whenever you need them. Here is what to check.

  • Open export formats
  • Audit trail and signatures included
  • Configuration export

Key points

  • Sponsors are responsible for trial data and must be able to retain and retrieve it for the required retention period, whichever vendor holds it.
  • Portable data means clinical data in open formats (such as CSV) with a data dictionary, plus the audit trail, signed records and study design.
  • Check export completeness: all forms, all participants, all versions, including deleted or changed values in the audit trail.
  • Agree exit terms in the contract: formats, timelines and costs for a full export at the end.
  • Capture exports CSV and Excel with a data dictionary, raw and decoded files, the audit trail, signed consent PDFs, blank eCRF and ePRO PDFs, and study configurations.

Why it matters

Lock-in happens quietly

Vendor lock-in rarely comes from a single decision. It builds up: data in a proprietary format, an audit trail that can only be viewed on screen, study designs that cannot be reused elsewhere, and exit fees nobody read in the contract. When a sponsor wants to switch vendors, merge data from several studies, or respond to an inspection years later, those gaps become expensive.

The answer is to treat portability as a requirement from the start. Test exports during evaluation, check that they are complete and documented, and write exit terms into the contract. See the EDC RFP template for questions to include.

Retention

Trial records must be kept for years after a trial ends, with the exact period depending on the regulations that apply. Plan how data will be retained and retrieved after the study closes, including if you stop using the vendor.

Exports you can use without us

Clinical data exports as CSV or Excel with an automatic data dictionary, in raw and decoded versions, filtered by date range, site or participant. Signed consent documents export as PDFs with embedded signature data, and study configurations export for reuse in a new study.

  • Open formats with a data dictionary.
  • Audit trail and signed PDFs.
  • Configuration export and import.

Questions to ask

What to ask every vendor

Can we export all clinical data, at any time, without a support ticket? Does the export include a data dictionary? Can we export the full audit trail, including values that were changed? Can we export signed consent documents with their signature evidence? Can we export the study design in a reusable form? What happens to our data at the end of the contract, in what format, how quickly, and at what cost?

Ask for an example export during evaluation and open it yourself. If it takes a vendor project to produce, it will take one again when you need it. See how to switch EDC vendors mid-study.

FAQ

Questions teams ask before they switch

Something not covered here? Ask us directly.

How long must trial records be kept?

It depends on the regulations that apply; many require retention for years after the trial ends.

Can we export while the study is running?

Yes. Exports are available at any time, filtered by date range, site or participant.

Who owns clinical trial data?

The sponsor is responsible for trial data and its retention. Contracts should confirm the sponsor's rights and how data is returned.

What formats should exports use?

Open formats such as CSV, with a data dictionary, plus PDFs for signed documents and blank forms.

Can the audit trail be exported?

In Capture, yes. It can be filtered by participant and date and exported.

Can we reuse a study design elsewhere?

Capture exports blank eCRF and ePRO PDFs and study configurations that can be imported into a new study.

Can exports be filtered to one participant?

Yes. CSV and Excel exports can be filtered to one participant, one site or a date range.

Can I try the exports free?

Yes, in the free sandbox with sample data.
