Clinical Trials: FAQs

Your decision to participate in a clinical trial involves many factors, including transportation, academic and/or job responsibilities, personal responsibilities, and family support. Remember, you are free to change your mind and drop out of the trial at any time. Please note, most trials require or strongly encourage a safety evaluation (exam and blood test) before you permanently withdraw.

If you have any additional questions that are not answered below, please don't hesitate to reach out to Karen Ahern via email or at (434) 924-1549.

What is a clinical trial?

A clinical trial is a scientific study that tests the effectiveness of a treatment, device, or drug. A trial could test, for example, the effectiveness of blood pressure medication in lowering blood pressure or whether a certain drug could decrease cholesterol.

Why should I participate in a clinical trial?

It's a way to help yourself and to help others. It provides an opportunity for you to help increase knowledge by helping researchers find out if a particular drug or therapy is safe and effective. While it is difficult to predict whether your condition will improve or how much it will improve, participation in a trial may be good for your health. It has been shown, for example, that even patients receiving the placebo (the inactive drug) in clinical trials frequently do better than patients outside of the trials.

Why are clinical trials needed?

Medical science is always looking for better solutions to treat illnesses and diseases. Before a medication or a treatment can be used on a patient, it must be carefully tested in a standardized manner for effectiveness and safety. Most likely, every doctor-prescribed medication that you use was first tested in a clinical trial.

Can anyone participate in a clinical trial?

This depends on the specific research goals of each trial. You must meet the requirements of the trial that you are interested in participating in.

What are the risks?

There are possible risks, such as adverse events or side effects, to consider when participating in any clinical trial. Participants are informed of known risks or side effects before starting the trial. Risks also are explained in the informed consent document. Make sure you fully understand them. There is always the possibility of unknown risk. If any new side effects or risks are discovered during the trial, you will be informed.

What does informed consent mean?

You must be fully informed and consent to participate in a clinical trial. Informed consent involves a discussion between you and the investigator or research team member about what is involved in the trial, its purpose, risks, procedures, your compensation and who you should contact if you have questions. You are encouraged to ask questions during the discussion, so you understand what you are signing. Informed consent also requires you to sign and date the consent form.

What is the role of the Institutional Review Board for Health Sciences Research (ISB-HSR)?

UVA's Institutional Review Board for Health Sciences Research (IRB-HSR) includes health care professionals and members of the local community. The purpose of this committee is to monitor the safety and protect the rights of human research subjects or participants in research. The committee continually reviews clinical trial developments and activities, as well as their risks and benefits.

Are there benefits to participating in a clinical trial?

You may be paid a stipend and/or costs to cover mileage, travel time, and meals. Participants may receive free medical care visits for the study, certain free medications, free diagnostic tests, laboratory procedures, and free parking.

Who will I work with?

Once accepted in a trial, you will meet the principal clinical investigator (the health care provider who is responsible for the trial.) Members of the research team you will see on a regular basis include the clinical trials coordinator(s) and research assistant(s).

What will I have to do to participate in a clinical trial?

Clinical trials vary in what they require of a subject, but typically:

  • You must make a commitment in time and be willing to follow the directions and instructions of the research team.
  • Periodic routine checks generally take ½ hour to two hours. The number of visits and the length of the visits depend on the type of trial.
What happens after I enroll in a clinical trial?

A typical trial proceeds in several phases:

A screening visit:

  • The informed consent is reviewed with you.
  • Blood is tested (if indicated for the trial).
  • Your medical history is taken.
  • You have a physical exam to determine if you meet the trial's requirements (if indicated).
A baseline visit (may be combined with the screening visit).
Routine study visits are periodic visits throughout the study to test blood, administer the study drug and check your condition.
Interim visits are added for unexpected problems or extra tests.
How long do clinical trials typically last?

It depends on the trial; they can vary from one day to a number of months or even years. You will be told the expected length of the trial before you start. This information is discussed with you during the informed consent process.

Will I know the results of the clinical trial?

Usually, you are informed of the results of tests performed during the trial. You will always be informed of results that might influence your decision to remain or withdraw from the trial. Medical information may not be shared if the study is blinded (see glossary) or until the trial is completed.
