Qualifying for a Clinical Trial
There are many different phases of clinical trials. Every step will build more information from the previous trial.
Some people qualify for a particular phase because of their health or illness.
Defining the Different Phases
In Phase I, a doctor will provide new treatment to a small group of people. They want to test the safety of the drug.

Researchers will determine the best route to give the medicine. They will also study the possible side effects and find the best dosage. In phase II, researchers determine how the treatment works for a specific illness.
In phase III, the team will compare this treatment with standard treatment.
Researchers see if there are effects of different dosages or combinations of medicines. They’ll see how treatments affect various populations like young, old, and ethnic groups.
In Phase IV, the treatment will get tried on typical patients. They look for side effects not present in the other phases. The researchers will also determine how the treatment worked out long-term.
The FDA will let drug makers market their treatment in this phase. Clinical trials will help save lives and even the lives of participants.
Advantages of Participating in a Clinical Trial
You’ll get to try a new treatment before it’s released to the public. Researchers will use the information they gather and create improved treatments. Learn more about the benefits.
The agency will usually pay for the tests and doctor visits. Always ask about the costs before beginning the trial.
Potential Problems
Any medical treatment will usually carry a degree of risk.
The risk will depend on your overall health and the type of treatment. During a clinical trial, researchers aren’t going to know the effects of the treatment on your body. That’s why they conduct the tests.
Can You Take Your Regular Medications During a Clinical Trial?
During a clinical trial, expect to undergo more tests and exams than you’re used to and follow-ups from doctors.
The researchers and doctors will collect lots of information. You might need to either change or stop your current medications.
You should always talk to the doctor in advance if this is a concern. Find out what you’ll need to stop.
Talk to Your Doctor
Speak with your primary healthcare provider before participating in a clinical trial. Your doctor can help you make an informed decision.
Talk to your doctor about the potential implications.
Consider Participating in a Clinical Trial
Some Americans decide to participate in a clinical trial for different reasons. If you’d like to join a study, make sure you talk to your doctor. You should also find out if you can take your regular medications.
