Clinical Trial Phases

Cancer clinical trials involve research at three different phases. Each phase addresses different questions about the new treatment.

Phase I Trials

This is the first step in testing a new treatment in humans. In these studies, researchers look for the best way to administer an experimental drug. They also try to find out if and how the treatment can be given safely, watching for any harmful side effects. Because little is known about the possible risks and benefits, these studies usually include only a limited number of patients who would not be helped by standard treatments.

Phase II Trials

This phase focuses on learning whether the experimental drug has an anti-cancer effect. Again, only a small number of people take part because of the risks and unknown variables involved.

Phase III Trials

This phase compares the results of people taking the experimental drug with the results of people receiving the standard treatment. Studies generally move into Phase III testing only after a drug shows promise in the first two phases. Phase III trials may include hundreds of people around the country.
