Cancer Clinical Trials

Medically Reviewed by Sabrina Felson, MD on November 07, 2022

Major pharmaceutical companies continually research and develop new cancer medications and treatments, which must be shown to be safe and effective before doctors can prescribe them to patients. Through cancer clinical trials, researchers test the effects of new drugs on a group of volunteers with cancer. Following a strict protocol and using carefully controlled conditions, researchers evaluate the drugs under development and measure the ability of the new drug to treat cancer, its safety, and any possible side effects.

Some patients with cancer are reluctant to take part in clinical trials for fear of getting no treatment at all for their cancer. This is simply not true. Patients with cancer who participate in cancer clinical trials receive the most effective therapy currently available for their cancer -- or they may receive cancer treatments that are being evaluated for future use. These cancer treatments may be even more effective than the current cancer treatment. The only way to determine if the newer treatment is better than the currently available treatment is by clinical trial participation.

The following websites offer information and services to help you find a cancer clinical trial that is right for you.


This website, developed by the nonprofit Coalition of Cancer Cooperative Groups, is an unbiased cancer clinical trial matching and navigation service enabling patients to search for cancer trials based on disease and location. It has now merged with a cancer decision-support platform called eviti, which contains treatment guidelines.
