Understanding Clinical Trials

What Is a Clinical Trial?
Clinical trials are research studies that are performed in people to test the effectiveness and safety of a new therapy that has shown promise in laboratory or animal studies. Such a therapy is also commonly referred to as investigational or experimental. The therapy can be a new drug or other treatment approach, such as radiation therapy or gene therapy, or a new combination of drugs or treatment methods. While clinical trials are done to study the prevention of illness, clinical trials are also a valuable option for many people who have been diagnosed with a serious disease, such as cancer. This may be especially true for those in whom the best standard cancer treatments are not working.

Cancer clinical trials are sponsored by government agees such as the National Institutes of Health, National Cancer Institute, pharmaceutical companies, and individual hospitals or treatment centers. People can participate in cancer clinical trials at hospitals, medical colleges, doctors' offices, or community cancer centers. Some clinical trials offer payment, while others do not.

What Is the Purpose of the Trial Phases?
Before a treatment is approved by the US Food and Drug Administration (FDA), it is studied in three stages, or phases, of clinical trials:

Phase I: In a phase I clinical trial, doctors have observed promising results with the new treatment in animal or laboratory studies, but do not know for sure what the effectiveness and side effects will be in people. The purpose of this type of trial is to find out how and how much of the treatment can be given safely.

Phase II: A phase II clinical trial is conducted after a phase I clinical trial. This type of trial is designed to see if the drug is effective against the disease. Patients receive the highest treatment dose that did not cause severe side effects in the phase I clinical trial. Doctors then evaluate carefully the effect of the treatment on cancer, as well as any side effects that occur.

Phase III: A phase III clinical trial is performed after a phase II clinical trial. This type of trial involves the treatment of large numbers of patients and serves to compare the new treatment to the best standard treatment. One group (called the control group) receives the best standard treatment, while the other group receives the new experimental therapy. The patients may not know which treatment they are receiving. If patients experience side effects that are too severe-or if one group's treatment is far more effective than the other-the study will be stopped.

Who Can Participate in a Clinical Trial?
For each clinical trial, there are guidelines stating who can participate in the trial (called inclusion or eligibility criteria) and who cannot participate (called exclusion criteria). These criteria are based on many factors, including type of cancer, stage of cancer, previous treatment received, and patient age and overall health. In addition, a study protocol describes the inclusion and exclusion criteria; the schedule of tests, procedures, medications, and dosages; and the length of the study.

What Are the Risks and Benefits?
There is some risk in participating in a clinical trial, such as the occurrence of side effects. However, there is also the potential benefit of receiving a new therapy that has activity against your cancer. In general, people who enroll in a clinical trial receive excellent, high-quality care. The research team includes doctors, nurses, social workers, and other healthcare professionals. These professionals follow each patient's health closely, before, during, and after the study. Importantly, people who enroll in a clinical trial are free to leave the study at any time, for any reason.


Finding a Clinical Trial

If you are interested in participating in a GI cancer clinical trial, the best first step is to ask your doctor for his or her recommendation. You may also search cancer clinical trials nationally, and discuss these options with your doctor. There are numerous cancer clinical trials listings available, including the following:

NewYork-Presbyterian Hospital
