Preparing for Clinical Trial Participation
What to Expect If You Join a Clinical Trial
Thinking about joining a clinical trial? Knowing what’s ahead can help you feel more in control and ready to take the next step. Here’s a breakdown of what typically happens—from your first conversation to life after the trial ends.
Questions To Ask Your Care Team
Once you’ve been referred to a study, these questions can help you understand what to expect, how it might affect your daily life, and what kind of commitment it requires.
What Will the Process Look Like?
- What kinds of tests, procedures, or medications are part of the trial?
- Will I need scans, biopsies, appointments, or bloodwork more often than usual?
- How is the treatment given (pill, injection, IV)?
What Are the Risks?
- What short-term side effects might I have?
- Could there be long-term or permanent effects on my health, fertility, or body?
- How will side effects be managed during the study?
What’s the Time Commitment?
- How long will each visit take?
- How often will I need to come in for treatment or monitoring?
- Will I ever need to stay overnight at the hospital?
What Happens After the Trial?
- Will the research team need to check in with me after the trial ends?
- If so, how long will that follow-up last, and what will it involve?
Signing the Consent Form
If a trial looks like a good match, the first official step is signing a consent form. This document confirms that:
- You understand the purpose of the study
- You’ve been told about risks, potential benefits, and available alternatives
- You know your rights as a patient
Keep asking questions until it all makes sense. There’s no such thing as “too many questions” when it comes to your health. You can also take the consent form home to review further before signing. Once you sign, you’ll move on to screening. Be sure to keep a copy of the form with your medical records in case this information can be useful for other healthcare providers.
Screening Appointment
Every trial begins with a screening appointment to confirm you meet the eligibility requirements. This might include:
- Blood tests
- Imaging (like a CT scan or MRI)
- Physical exams
- Health surveys
Each study is different. The research team will go over what to expect during the consent process so you won’t be caught off guard.
Starting Treatment and Regular Appointments
On your first day—and throughout the study—you’ll have regular clinic visits for labs, check-ins, and treatments. How often you come in (and for how long) depends on the specific trial.
Tips to make treatment days easier:
- Bring any medications you take at home, in their original bottles
- Stay hydrated
- Dress in layers for comfort. Wear:
- Short sleeves if you’ll be getting an IV
- A zip-up or button-down if you have a port
- Pack things to pass the time: headphones, music, books, or a tablet
Leaving or Ending a Trial
You always have the right to leave a clinical trial, no matter the reason, no pressure. Otherwise, a trial might end for one of the following reasons:
- You’ve completed the treatment period
- You or your care team decide to stop early due to unexpected side effects or lack of benefit
- You choose to exit the trial for personal reasons
Some participants are in a trial for just a few weeks, others for months or even years. Every experience is unique and your voice matters in every decision.
After the Trial: Follow-Up Care
Just because the trial ends doesn’t mean your connection with the study team does. Some trials require follow-up care to track how you’re doing long-term. This may include:
- Check-in phone calls
- Routine in-person visits
Think of it as one more way to contribute to better care for yourself and others.
Understanding Costs and Insurance Coverage
If you’re thinking about joining a clinical trial, it’s important to understand what it might cost—and what will be covered. Every trial is different, so take the time to talk with your study team and your insurance provider to get clarity upfront.
In many cases, the medicine being studied in a clinical trial is provided at no cost. Travel expenses and other costs may also be paid for by the trial sponsor (the organization or person funding the research). But that’s not always the case.
