We are creating a unified UKRI website that brings together the existing research council, Innovate UK and Research England websites.

Clinical trials data sharing: ReShare

The MRC strongly encourages the sharing of the rich and diverse datasets from clinical trials for use in further research, as this offers valuable opportunities for new research, discoveries and collaborations.

ReShare, at the UK Data Service provides a national repository for research data which MRC funded researchers can use.

UKDS ReShare


We encourage researchers to consider using the UK Data Service (UKDS) ReShare  facility, which is a data repository suitable for clinical trials data. UKDS staff help researchers to prepare and deposit their data.

Researchers who deposit data in ReShare decide whether access is fully open or controlled (‘safeguarded’) and UKDS staff can help with this decision.

Safeguarded access means that applications to use the data must first be approved, which helps to protect the confidentiality of participant data.

UKDS staff will help researchers manage access requests for safeguarded datasets held in ReShare.

If access is approved, UKDS manage release of the data to the researcher under an end user licence.

ReShare offers:

  • A searchable catalogue for listing datasets
  • A permanent data repository
  • A unique DOI (digital object identifier) to identify the dataset
  • End user licenses for researchers accessing data
  • Guidance on preparing data

Credit for data sharing

Research teams who share their data should receive credit for this. For example, data sharing agreements should require that the original research team are acknowledged in publications using the shared data, or that a dataset (DOI) is cited to enable tracking of outputs.
