This site (CSDR) is a consortium of clinical study data providers. It is a leader in the data sharing community inspired to drive scientific innovation and improve medical care by facilitating access to patient-level data from clinical studies.

Access to clinical trial data provides opportunities to conduct further research that can help advance medical science or improve patient care. This helps ensure the data provided by research participants are used to maximum effect in the creation of knowledge and understanding.

Researchers can use this site to request access to anonymised patient level data and/or supporting documents from clinical studies to conduct further research.

Next steps

Study sponsorsStudy sponsor means a person who takes responsibility for and initiates a clinical investigation. The sponsor may be an individual or pharmaceutical company, governmental agency, academic institution, private organisation, or other organisation. who have committed to use this site are Astellas, Bayer, Boehringer Ingelheim, Daiichi Sankyo, Eisai, GSK, Lilly, Novartis, Roche, Sanofi, Takeda, UCB and ViiV Healthcare.

Other clinical trial sponsors and funders are invited to join with the aim of transitioning to a fully independent system which allows access to data from clinical trials conducted by multiple companies and organisations. It is hoped that such a system will be put in place as soon as possible.

If you are a study sponsor interested in listing studies on this site, contact information is provided here.


Researchers can submit research proposals and request anonymised data from clinical studies listed on this site.

Researchers can also submit enquires to some study sponsors to ask about the availability of data from studies that are not listed on this site.

It is also possible to request or access study documents without patient-level data.

Information on sponsor’s criteria for listing clinical studies, accessing study documents, and other relevant sponsor specific information is provided in the Study sponsors section.


Research proposals are reviewed by an Independent Review Panel. The study sponsors are not involved in the decisions made by the panel.


Following approval and after the relevant study sponsor or sponsors receive a signed Data Sharing Agreement, access to the data needed for the research is provided on a password protected website.
