Decision Support Tool: Features to Consider in Determining if a Clinical Trial is Phase II or Phase III

November 2022

A working group led by OBSSR, with participants from other NIH Institutes, Centers, and Offices, releases the Decision Support Tool: Features to Consider in Determining if a Clinical Trial is Phase II or Phase III. It is designed to be a resource to help investigators, program officers, and reviewers determine whether a behavioral or social sciences study is better characterized as a Phase II or a Phase III clinical trial.
