Finding a Clinical Trial

Approved by the Cancer.Net Editorial Board, 05/2022

Cancer researchers are constantly creating new clinical trials to help find ways to improve cancer treatment, care, and prevention. Many organizations list open clinical trials online to help people find a research study that may be appropriate for them. Below are resources, lists, and searchable databases that can help you find a cancer clinical trial you may be interested in joining. Please note that links will take you to another, independent website. Always talk with your doctor about your clinical trial options.
