If you’re thinking about joining a clinical trial, here’s what the process usually looks like from start to finish.
Step 1: Find a Study
You might hear about a study from your doctor, see an ad online, or search for opportunities through a research site like Tekton. You can also browse ClinicalTrials.gov, a public database of clinical studies.
If you’re looking for studies near you, you can start with Tekton’s Find a Study page.
Step 2: Initial Contact
When you express interest in a study, someone from the research site will reach out, usually by phone, text, or email. They’ll ask a few basic questions to see if the study might be a good fit.
That may include your age, medical history, current medications, and details about the condition being studied.
This first screening is usually quick. If the study doesn’t seem like a match, the team may suggest another study or ask if they can keep your information for future opportunities.
Step 3: First Visit to the Research Site
If the first screening goes well, you’ll schedule a visit to the research site. This is when things start to feel more real.
During this visit, the research team walks you through the study: what it’s testing, what previous research has shown, what your participation would involve, possible risks and benefits, and how many visits you’d need to make.
This is the time to ask questions. Lots of them. The research team expects it.
Step 4: Informed Consent
If you’re still interested after learning the details, you’ll go through the informed consent process. This isn’t just signing a form. It’s a conversation.
The team will review the informed consent document with you. You’ll learn what treatment or study product you may receive, what tests you may have, possible side effects, your rights as a participant, and what happens if you decide to leave the study.
Take your time. You may be able to bring the document home to review. You can ask to speak with your regular doctor. You can bring a family member or trusted friend to an appointment.
There’s no pressure to decide on the spot. When you’re ready, and you understand what’s involved, you can choose whether to sign the consent form.
Step 5: Screening and Medical Evaluation
Before you start the study, you’ll have a medical screening to help make sure the trial is appropriate and safe for you.
This may include:
- A physical exam
- Blood tests or urine tests
- An ECG or other heart monitoring
- A review of your medical history
- A pregnancy test, if applicable
- Condition-specific tests
The screening visit can take a few hours. Some studies require more than one screening visit.
If the screening shows the study isn’t the right fit, or if you don’t meet all the study requirements, you won’t be able to participate. The research team will explain why and may be able to suggest other studies.
Step 6: Randomization, If Applicable
Many clinical trials use randomization. That means participants are assigned by chance to a study group.
You may receive the investigational treatment, a comparison treatment, standard treatment, or a placebo. A placebo looks like the study treatment but doesn’t contain the active ingredient.
You won’t choose which group you’re in. Depending on the study, you may not know which treatment you’re receiving. This is called “blinding,” and it helps researchers get more reliable results.
The informed consent process will explain all of this ahead of time, so you’ll know what to expect before deciding whether to join.
Step 7: Treatment Period
Once you’re enrolled, you start the study treatment or study procedures. This is when you become an active participant.
What this looks like depends on the study:
- You might take a pill at home
- You might come to the site for injections
- You might receive infusions that take several hours
- You might track symptoms in a diary or app
- You might have regular tests, scans, or check-ins
During the treatment period, the research team monitors you closely. Study visits may include:
- Questions about side effects
- Physical exams
- Blood draws
- Scans or other tests
- Questionnaires about your symptoms or daily life
You’ll usually have a direct contact, often a study coordinator, who you can call between visits if you have questions or concerns.
Step 8: Follow-Up Period
After the treatment period ends, many studies include a follow-up phase. The research team continues checking on your health and safety, even if you’re no longer receiving the study treatment.
Follow-up may involve:
- Clinic visits
- Phone check-ins
- Final medical assessments
This part of the study helps researchers understand what happens after treatment ends.
Step 9: End of Study
When your participation ends, you’ll usually talk with the research team about what comes next.
Good questions to ask include:
- What happens now that the study is over?
- What care options should I talk about with my regular doctor?
- Will I be told anything about my individual results?
- When will the overall study results be available?
- How can I find out what the study learned?
Some studies may offer an open-label extension. That means eligible participants may be able to receive the investigational treatment while researchers continue collecting long-term information. Not every study offers this, so it’s worth asking about.
Step 10: Results
After all participants complete the study, researchers analyze the data. This takes time. Sometimes months. Sometimes longer.
Whether you’ll receive individual results depends on the study. Some studies share results with participants, and others don’t. Overall study results may also be published in medical journals or posted in public databases.
Many participants never see the final results, which can be frustrating after giving time and energy to a study. If receiving results matters to you, ask about it during informed consent.
One More Thing
Throughout all of this, remember: taking part is always your choice.
You can leave a clinical trial at any time, for any reason, without affecting your regular medical care. The research team wants you there only if you want to be there.
