Before the U. If these studies show favorable results, the FDA gives approval for the intervention to be tested in humans. Clinical trials advance through four phases to test a treatment, find the appropriate dosage, and look for side effects.
If, after the first three phases, researchers find a drug or other intervention to be safe and effective, the FDA approves it for clinical use and continues to monitor its effects. Clinical trials of drugs are usually described based on their phase. Like Mr. Jackson, you might have heard of clinical trials but may not be sure what they are or if you want to join one.
Here is some information that can help you decide if participating in a clinical trial is right for you. There are many reasons why people choose to join a clinical trial. Some join a trial because the treatments they have tried for their health problem did not work. Others participate because there is no treatment for their health problem.
By being part of a clinical trial, participants may find out about new treatments before they are widely available. Some studies are designed for, or include, people who are healthy but want to help find ways to prevent a disease, such as one that may be common in their family.
Many people say participating in a clinical trial is a way to play a more active role in their own health care. Other people say they want to help researchers learn more about certain health problems.
Whatever the motivation, when you choose to participate in a clinical trial, you become a partner in scientific discovery. And, your contribution can help future generations lead healthier lives. Major medical breakthroughs could not happen without the generosity of clinical trial participants—young and old.
Humans and mice can be very different in the way they absorb, process, and get rid of drugs or treatments. A treatment that works against cancer in a mouse might or might not work in people.
If the pre-clinical studies are completed and the treatment still seems promising, the US Food and Drug Administration FDA must give permission before the treatment can be tested people.
Before a clinical trial can be started, the research must be approved. An investigational new drug or IND application or request must be filed with the FDA when researchers want to study a drug in humans.
The IND application must contain certain information, such as:. The research sponsor must commit to getting informed consent from everyone on the clinical trial. They must also commit to having the study reviewed by an institutional review board IRB and following all the rules required for studying investigational new drugs.
Clinical trials are usually conducted in phases that build on one another. Each phase is designed to answer certain questions. Knowing the phase of the clinical trial is important because it can give you some idea about how much is known about the treatment being studied. There are benefits and risks to taking part in each phase of a clinical trial. Although there are clinical trials for devices as well as other diseases and treatments, drugs for cancer patients are used in the examples of clinical trial phases described here.
The purpose of this phase is to help speed up and streamline the drug approval process. This may help save time and money that would have been spent on later phase trials. Rather, we oversee the people who do. FDA staff meet with researchers and perform inspections of clinical trial study sites to protect the rights of patients and to verify the quality and integrity of the data.
Learn more about the Drug Development Process. One good way to find out if there are any clinical trials that might help you is to ask your doctor. Other sources of information include:. A placebo is a pill, liquid, or powder that has no treatment value. It is often called a sugar pill. In clinical trials that include placebos, quite often neither patients nor their doctors know who is receiving the placebo and how is being treated with the experimental drug.
Many cancer clinical trials, as well as trials for other serious and life-threatening conditions, do not include placebo control groups. In these cases, all participants receive the experimental drug. Ask the trial coordinator whether there is a chance you may get a placebo rather than the experimental drug. Then, talk with your doctor about what is best for you.
