Cancer Clinical Trial Phases

One of the University of Wisconsin Carbone Cancer Center's greatest strengths is its involvement in groundbreaking clinical trials.
 
Clinical trials are generally conducted in three phases:

Phase I
 
Phase I clinical trials are designed to identify the best way to give new treatments and the most appropriate dose. Information about dosage and side effects will then be used in future studies.
 
Anywhere from 12-50 patients with various types of cancer participate in Phase I studies. University of Wisconsin Carbone Cancer Center is unique in offering Phase I clinical trials as part of a patient's treatment plan since only certain facilities are able to conduct these types of studies.
 
Phase II
 
Phase II clinical trials are studies assessing the effectiveness of a treatment against specific types of cancer. Typically no more than 100 patients participate in each study.
 
Treatments proven to be as effective as the current available therapies will be studied in Phase III clinical trials.
 
Phase III
 
Phase III clinical trials compare the current treatment to the treatment proven to be as effective from Phase II clinical trials.
 
Many patients from across the country participate in these studies. Every patient involved in a Phase III study receives either the new treatment or the current treatment. Patients never receive a placebo in place of the best known treatment available for a given cancer.
