Frequently asked questions

What does recruiting mean?
Recruiting means the study is currently enrolling participants. Not yet recruiting means it has been registered but has not started enrolling. Enrolling by invitation means participants are selected by the study team rather than through open enrollment.
How do I join a clinical trial?
Read the full eligibility criteria and contact information on ClinicalTrials.gov, then talk with your doctor about whether a study may be right for you. The study team decides who can enroll.
