PATIENT GUIDE
Joining a clinical trial involves searching, screening, and enrolling — a process that usually takes a few weeks. Here is a plain-language walkthrough of every step.
Informational only. Not medical advice. Always consult a qualified healthcare professional before making decisions about clinical trial participation.
Start by searching for trials by condition and location on Clinicals AI or ClinicalTrials.gov. Filter for 'Recruiting' status — these are actively accepting new participants. Note the trial ID (NCT number) for any study that looks relevant.
Every trial has inclusion criteria (who can join) and exclusion criteria (who cannot). Common requirements include age range, specific diagnosis, prior treatment history, and general health status. Read these carefully before contacting the study team — it saves everyone time.
Submit a contact request on Clinicals AI or call the contact number on the trial listing. The study coordinator will ask screening questions by phone or email. This is informal — it is just to determine if you might be eligible before scheduling a screening visit.
If initial screening looks promising, you'll be invited for a formal screening visit at the trial site. This may include a physical exam, blood tests, imaging, or other assessments to confirm eligibility. Screening visits are typically free even if you don't enroll.
If you're eligible, you'll receive an informed consent document explaining the study in full detail. Take time to read it carefully. Ask questions — you have a right to understand everything before agreeing. Signing it means you agree to participate, but you can still withdraw later.
After consent, you are officially enrolled. You'll receive a study schedule, contact information for your coordinator, and instructions for your first visit. Keep your regular physician informed — they should know you are participating in a trial.
COMMON QUESTIONS
How long does it take to join a trial?
From first contact to enrollment typically takes 2–6 weeks, depending on how quickly the study team responds and how complex the screening process is.
Do I need a doctor's referral?
Not always. Many trials accept self-referrals — you can contact the study team directly. However, your physician's involvement is still recommended for your own safety.
What if I'm not eligible for one trial?
Eligibility criteria are very specific. Not qualifying for one study doesn't mean you won't qualify for others. Search for additional trials on Clinicals AI — there may be several studies for your condition.
Can I be in more than one trial at a time?
Usually not. Most trials require that you are not currently enrolled in another interventional study, as concurrent treatments would interfere with results.
