Request Access

Qualified researchers can request access to RDoCdb shared data. To get started, create an NDA account or login to your existing one. Once approved, you'll have access to query and download all data available in the repository. Summary data is available to all. The best place to get started viewing data in RDoCdb is the RDoCdb Data Dictionary..

To request access, follow these steps:

  1. Create an account.

  2. Log in and go to your Data Permissions dashboard.

  3. Complete the access request instructions.


The Data Permissions Dashboard is a single location you can access with your account and use to request or renew access electronically to one or many repositories in NDA, including NDCT, RDoCdb, NDAR, and others. For detailed information on the process or criteria for access, visit Access Review

If you are unable to complete the automated DUC process, you can also complete the PDF manually and email a signed copy to
