Research Participants and Public

Are you or is someone you know thinking about participating in a clinical trial? Are you interested in finding out more about clinical trials?

Participation in a clinical trial (also called a research study) may be an option for a person with cancer or someone at risk for developing cancer. Before deciding whether a clinical trial is an option for you or someone you care about, it’s important to learn all you can.

What are clinical trials?

Clinical trials are research studies involving people. They test new ways to prevent, detect, treat or manage cancer or other diseases. Clinical trials test whether new approaches are safe and how well they work to see if they should become widely available. Most of the standard cancer treatments used today were first tested in clinical trials, thanks to innovative researchers and to people who volunteered to take part in clinical trials.

How do I find out more?

The Canadian Network of Networks (N2) has developed excellent information about clinical trials, including a video and examples of questions to ask before deciding whether or not to participate in a trial. N2 is a not-for-profit organization that is collaborating with the research community to promote excellence in clinical trials in Canada. N2 has been working together with patients and caregivers to develop information that will help potential participants, families, caregivers and the general public to learn about clinical trials. For more information, visit N2 – It Starts with Me.

The Canadian Cancer Society also provides a wealth of information about cancer and clinical trials. Visit their website at Canadian Cancer Society – Clinical Trials.
