A clinical trial is a study of a new or different way to treat
cancer. Often medicines or other treatments that are not yet proved to be
effective with a particular cancer are tested. Such treatments might include
hormonal therapy, immunotherapy, chemotherapy, or new surgical
People participating in clinical trials receive all other recommended
treatments for their cancer and are closely monitored.

Benefits From Finasteride and Dutasteride Chemoprevention
Based on solid evidence, chemoprevention with finasteride and dutasteride reduces the incidence of prostate cancer, but the evidence is inadequate to determine whether chemoprevention with finasteride or dutasteride reduces mortality from prostate cancer.
Participants in trials must meet the specific guidelines that each
clinical trial has in order to be a part of the trial. Sometimes the clinical
trials are conducted at major medical centers. Other times the trial
participant receives treatment by the primary care doctor at home.
