Join the Pathfinder 2 Study

Please Note: The project is officially ending late June 2024,

and we are no longer taking any new sign-ups.

What is the Pathfinder 2 Study?

Too often, cancer is not found until it is already very serious. Thinking about cancer can feel scary, but trying to find cancer early can help you feel more in control of your health. Early detection increases the chances of surviving cancer.

The PATHFINDER 2 Study looks at how well a new test called Galleri can find cancers early. Galleri is designed to find many types of cancer using a simple blood test. Right now, this test is still being studied and has not been approved or cleared by the Food and Drug Administration (FDA). It is still important to follow your healthcare provider’s recommendations about cancer screening tests, such as colonoscopies or mammograms.

What is Galleri?

The Galleri test looks at a sample of blood for any signs of possible cancer. While it can find the possibility of cancer in blood samples, it cannot tell you your genetic risk of having cancer in the future.

Can I join this study?

If you are 50 years or older, have not had cancer, or have been cancer free for at least 3 years, then you can be part of the PATHFINDER 2 Study. However, if you have participated in a GRAIL sponsored study in the past or are currently part of one, you will not be able to join this study. Please contact the study team if you have questions about joining.

What will I need to do?

• Read and sign an informed consent form that fully explains the study.

• Provide your medical history and allow access to your medical records.

• Get 40 milliliters of blood drawn by a medical professional.

• Fill out survey(s) at different times during the study
