|Welcome to the ClinicalTrials.gov Protocol Registration and Results System (PRS).||
This is a test version of the Protocol Registration and Results System (PRS). Creating or modifying records in this system will have no effect on the production (operational) PRS or ClinicalTrials.gov.
The data on this system is occasionally replaced entirely with a copy of the latest data from the production system. [Data last copied from production PRS: Feb 4, 2016] If you had an account on the production PRS at that time, the same login information should work on this system.
WARNING: Do not use the PRS Test System to prepare data for the production PRS. This system sometimes runs a software release that is not fully compatible with that of the production system.
If you notice problems or have questions while using this test system, please contact us using the Contact ClinicalTrials.gov PRS link (in the upper right corner, after logging in).
See Submit Studies on ClinicalTrials.gov for information on how to apply for a PRS account.
See PRS Guided Tutorials for assistance with entering registration and results information in the PRS.
Send email to ClinicalTrials.gov PRS Administration.
