The clinical trial enrollment process: what happens next?
Clinical trial enrollment involves information, eligibility assessment and consent, but the sequence depends on the study. A first enquiry does not enroll you, and research-specific screening may itself need consent. Ask the team which stage you are at, what happens next and what decision you are being asked to make.

Key takeaways
- Distinguish an initial enquiry from research screening and enrollment.
- Ask about consent before any research-specific procedures.
- Keep a clear next step and contact after every conversation.

Find a study and verify the contact
Check the official study record, identifier, current recruitment and local site. Read what participants actually do before contacting the team. Save the source and use a verified contact, particularly before sharing sensitive information. A recruiting label helps you find a lead; it does not confirm a place or your eligibility.
Understand first contact and research screening
A team may first ask basic questions about possible fit. Ask whether the conversation is preliminary or part of research screening. FDA guidance distinguishes initial discussion from procedures performed solely to determine research eligibility, which require prior informed consent. Ask what information is needed and how it should be shared securely.
Clarify consent, participation and follow-up
Request the participant information and ask how the consent discussion fits the actual schedule. You may need to understand different stages or documents. Ask what signing each document permits and what remains undecided. If you continue, keep copies, the visit plan and the contact for questions.
Keep track of the stage you have reached
A short note after each conversation can prevent confusion. Ask the team to confirm what has been completed and which decisions are still open. Use its terminology rather than assuming that screening, eligibility and enrollment mean the same thing.
| Check | Question to resolve |
|---|---|
| Enquiry | Is this only a request for information? |
| Screening | Which assessments and consent are proposed? |
| Eligibility | What still needs to be checked by the team? |
| Decision | What am I choosing, and how much time can I take? |
| Participation | Which visits and follow-up are now agreed? |
Discuss care and practical arrangements before deciding
Ask about visit length, travel, home tasks, costs and reimbursement. If the study proposes treatment changes, discuss them with your treating clinician and ask who coordinates care. Do not change medication or routines to qualify on the basis of a listing. Bring a supporter to the discussion if you want, subject to the team’s arrangements.
Plan for either outcome after screening
Ask what happens if you are not eligible or choose not to continue, especially after any research-related procedure or agreed care change. Clarify whether follow-up is proposed and who receives relevant information. If you do join, ask how to raise concerns or discuss leaving later.
Enrollment steps to expect
- Find a study from a credible source
- Verify the official registry or source page
- Contact the research team
- Complete screening questions or assessments
- Review informed consent and ask questions
- Confirm visits, risks, payment, privacy, and withdrawal options
Questions and answers
Does screening mean I am enrolled?
Not necessarily. Ask the team what screening involves and what still needs to happen before enrollment is confirmed.
Does consent always happen after screening?
No. Research-specific screening procedures may require consent first. Ask which discussions and documents apply at each stage.
Who confirms eligibility?
The research team assesses the study criteria. A public listing or a completed enquiry cannot confirm eligibility.
Can I decide not to continue?
Participation is voluntary. Ask about the next care steps and any proposed follow-up if you stop screening or decide against joining.
