The DUA is the product of extensive negotiation with the organizations that contribute data to Vivli, and as such, the agreement is non-negotiable. More than 85 institutions from 25 countries have already signed this agreement.

Does Vivli comply with the General Data Protection Regulation (GDPR)?

Yes, Vivli does comply with GDPR. Please see Vivli’s privacy policy.

What support do you offer users?

Vivli has a dedicated, responsive support team available to answer any questions and help you through the process of submitting or requesting data.

How do I create an account and log in to the Vivli platform?

Logging into the Vivli platform is easy! Check out our quick start guide to help you through the process.

What are benefits of data sharing?

  • Funders are increasingly mandating data sharing. The Gates Foundation, Wellcome Trust and many others are requiring that Individual Patient-Level Data from research they fund is shared. In addition, the updated NIH Data Sharing Policy went into effect January 2023. For many funders, data sharing costs are an allowable research expense and maybe built into future grant proposals and billed to current grants.
  • Top journals such as the NEJM, BMJ, Lancet and other ICMJE journals require that the data sharing statement is made at the time of trial registration. Journals are publishing the data sharing statement at the time of publication.
  • Moral obligations (owe it to trial participants). We owe it to participants of clinical trials who have volunteered to take part in this research for their data to be leveraged to maximize scientific knowledge. Surveys show that most participants want their data to be shared if adequate safeguards are in place.
  • Increase citations. Sharing detailed clinical research data is associated with increased citation rate.

What is the Vivli platform and how is it unique?

Vivli is an independent non-profit organization launched in 2016. Vivli evolved from a project of The Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard (MRCT Center) to enhance access to clinical trials data by promoting data sharing and transparency. In 2013, the MRCT Center and a diverse group of global stakeholders embarked on a mission to define, design, and launch an innovative platform solution for global clinical trial data sharing.

Vivli’s mission is to promote, coordinate, and facilitate clinical research data sharing through the creation and implementation of a sustainable global data-sharing enterprise. Vivli serves to meet the needs of researchers in all parts of the clinical research ecosystem. For those requesting data, Vivli provides managed access to data from completed clinical trials around the globe and facilitates the ability to integrate data from existing platforms and data repositories. For those seeking to contribute data, Vivli provides a secure, flexible, and user-friendly platform to facilitate sharing clinical trial data with the research community.

The Vivli platform provides access to anonymized individual participant-level data (IPD) or the raw data that is collected during a clinical trial. The clinical trials represented in Vivli are global and contributed by a diverse group of data contributors. By serving as a global trusted platform, Vivli increases the discoverability of available data in the wider research ecosystem, and increases the overall capacity worldwide for effective data sharing, aggregation, re-use, and novel analysis of valuable clinical research data to advance science and improve public health. The Vivli platform is a cloud-based platform that consists of a dynamic search engine, a data repository, and a secure research environment.

For more information about Vivli and the Vivli platform, please visit our About page.

What types of data are currently available through the Vivli platform?

Vivli features data from completed interventional studies in a number of therapeutic areas for which anonymized Individual Participant-level Data (IPD) are available as well as data from observational studies.

Requesting access to data

What kind of requests are accepted on the Vivli platform?

The purpose of the Vivli platform is to support research utilizing available clinical data leading to published analysis of a concrete scientific hypothesis. For more information about our members’ data sharing policies, please visit each member’s page on our website.

How do I access data available in the Vivli platform?

Users either can access the data by downloading it or have access to a remote desktop workspace in a secure virtual research environment. On the member’s page, a member will share if the data is available by download or within the research environment. Find out more about the secure research environment.

Once I’ve submitted a data request, how long will it be before my request is approved and I have access?

On average it takes a few months to access data in the Vivli platform, but the timeline will vary depending on the number of data contributors, the number of studies, and your availability to respond to comments. Learn more about the data request process here. Once the proposal is final, the Vivli member(s) will prepare the data for sharing and then upload data to the platform. Additionally, you may find it helpful to review our blog post: 10 tips and tricks for drafting a successful data request.

Can I access studies not listed on the Vivli platform?

To enquire about a study not listed on Vivli or to obtain additional information not included in a study listing, please submit an enquiry through the Vivli Platform. To submit an enquiry or request access to study data, you will need to create a Vivli Platform account. Additional information on how to get started is available in our guide to requesting studies on Vivli.

For more information on Vivli Members, please visit the Member Page. Some Members may require that enquiries be submitted via their own portals.

What tools and software does Vivli provide for data analysis?

As a Vivli user, you have access to a secure research environment, a virtual work-space within the Vivli platform, which contains a bevy of the most popular tools for statistical analysis and manuscript preparation, including SAS, STATA, R, Python, Jupyter, the Microsoft Office suite and a full set of tools and scripts (available on Secure Research Environment page linked above). If your preferred tools are not included in the standard set, the Vivli team may be able to add them for you subject to having the appropriate license and security requirements. Contact for any questions related to the uploading of additional tools, data and scripts.

Sharing data on the Vivli platform

Can I embargo my data set?

You can upload your data on Vivli before it is shared with others. The study would be listed on Vivli’s platform and would make note of the date when the study data will be available. Researchers can still request the data and it will be shared when the embargo period has ended.

Can I delete data I contributed to the Vivli platform?

You may update your data or request that your data is deleted by contacting the Vivli team at

How long will Vivli store my research in the Vivli platform?

At a minimum, Vivli will make data available for researchers for 10 years, unless they are contractually unable to do so. On an ongoing basis, Vivli evaluates its data holdings with regard to maintaining access and reserves the right to discontinue the distribution of a data collections when deemed appropriate.
When materials are deaccessioned, the data are no longer publicly accessible at Vivli, although they may still be preserved in Vivli’s storage vault. Because digital files are assigned a persistent digital object identifier (DOI), the study description is still available to view, but is not searchable through Vivli. Web crawlers are instructed to ignore the descriptions (via the robots exclusion protocol).

For more information about Vivli’s policy, please contact Vivli at

Does my data need to be related to a published article?

No, the data you share does not have to be published. However, the data must be affiliated with completed clinical research. We can meet publication requirements by sharing underlying data.
