Questions people ask
What does “recruiting” mean?
The study is enrolling participants now. “Not yet recruiting” means it is approved to start but enrolment has not opened; “enrolling by invitation” means the study team selects and invites participants.
How do I know if I can take part?
Each trial page lists who may join and who may not, the ages and sexes it accepts, and its sites and contacts. Only the study team can confirm eligibility, so take the record to your doctor and contact the team listed.
Does it cost anything to take part?
Most trials cover the cost of the treatment being tested and study visits, and some pay for travel or time. Each study is different: ask the study team what is covered before you agree to join.
Where does the information come from?
Every record comes from ClinicalTrials.gov, the registry run by the U.S. National Library of Medicine, as the sponsor submitted it. AzTrials copies the registry every night and links each trial to its official record.
