What to expect when you join a clinical trial

A clear walk-through of the steps involved, so you know what happens at each stage.

Clinical trials are how new treatments are carefully studied before they become widely available. If you've never taken part in one, the process can feel unfamiliar. Here's a plain-language overview of how a study typically unfolds — every trial is different, but most follow these general stages.

1. Pre-screening

It usually starts with a short conversation, by phone or in person, about your health history and the condition being studied. This helps our team get a sense of whether a particular study might be a fit before you come in.

2. Informed consent

Before any study procedures begin, you'll go through informed consent. This is a document and a discussion that explains the study's purpose, what's involved, the potential risks and benefits, and your rights as a participant. You can ask as many questions as you like, take the form home to review, and you are always free to decline or to stop at any time.

3. Screening visit

If you decide to move forward, a screening visit confirms whether you meet the study's specific requirements. This may include a physical exam, medical history review, and tests such as bloodwork. Not everyone who screens will qualify — the criteria are set to keep participants safe and the research sound.

4. Study visits

During the study you'll come in for scheduled visits. Depending on the protocol, these can involve check-ins, assessments, and monitoring by the research team. Our coordinators walk you through the schedule up front so you know the time commitment involved.

5. Follow-up

After the main part of the study, there is often a follow-up period so the team can check on how you're doing. Throughout the entire process, your safety and well-being come first, and you remain free to withdraw at any point without affecting your regular medical care.

Have questions?

The best way to understand whether a study is right for you is to talk it through with people who run them. Our team is glad to answer questions with no obligation to enroll.
