Description

Recruitment— Use this field to specify whether you want to search for studies that are open (recruiting participants) or closed (not recruiting participants). You may select one of the following search options:
  • All Studies—All studies, whether they are recruiting new participants or not
  • Open Studies— Studies that are currently recruiting participants, will be recruiting participants in the future, or involve drugs that are available for expanded access. Recruitment statuses for open studies appear in green text in ClinicalTrials.gov search results and study records. These are:

    Recruiting
    Not yet recruiting
    Available for expanded access


    Note: For open studies, the word "Unknown," in brown text, means that a study record with a Recruiting or Not yet recruiting status has not been verified in ClinicalTrials.gov within the past 2 years.
  • Closed Studies— Clinical studies that are no longer recruiting participants because they have enough participants already, because they are completed, or because they have been stopped for some reason. This also describes studies with very specific eligibility criteria that recruit participants by invitation only. Recruitment statuses for closed studies appear in red text in ClinicalTrials.gov search results and study records. These are:

    Active, not recruiting
    Completed
    Terminated
    Suspended
    Withdrawn
    Enrolling by invitation
    Temporarily not available for expanded access
    No longer available for expanded access
    Approved for marketing


    Note: For closed studies, the word "Unknown," in brown text, means that a study record with an Active, not recruiting status has not been verified in ClinicalTrials.gov within the past 2 years.

See Recruitment Status in the glossary for definitions of each status.
