Partnering for a Better Tomorrow
Clinical trial information for patients
Thomas Jefferson University conducts cutting edge research to advance science and medical treatments globally. By participating in clinical research you are investing in yourself, your community, and the future of research. It is our partnerships with our volunteers that help create breakthroughs and further medical knowledge and treatments. We pride ourselves on creating a research environment based on respect, trust, and compassion between our teams and volunteers and work together as one to improve the outcomes of many.
What is a Clinical Trial?
Clinical trials are research studies designed to test the effectiveness of drugs, devices, treatments or preventive measures in humans in a safe environment. Volunteers are the key to research that benefits us all.
With a team of globally renowned doctors and researchers we are here to partner with you for better outcomes tomorrow.
Frequently Asked Questions
What are the benefits of volunteering to take part in clinical research?
By participating in clinical research you may provide important scientific information for developing new disease treatments and further medical knowledge.
Are there risks or side effects in clinical studies?
There may be risks with any clinical study. The risks and benefits are reviewed in detail in the informed consent process. You are encouraged to ask questions throughout the consenting process and while you are in the study. There are no guarantees that the drug or device being studied will be effective. The principal investigator or study coordinator will explain the potential risks and the potential benefits before you sign the consent form and join the study.
What is a human subject?
A human subject is a volunteer participant who is or becomes involved in a research study. A subject can be either someone who is healthy or someone with a particular medical condition.
What is a clinical trial?
A clinical trial is a research study designed to test the safety and/or effectiveness of drugs, devices, treatments or preventive measures in humans.
What is informed consent?
Informed consent is required for participation in all research studies involving human subjects. Individuals are given information about what is involved in the study, including possible benefits and risks. Prospective study participants are encouraged to ask as many questions as they like. Below are some examples of the type of questions to consider before signing a consent form.
- What is the purpose of the study?
- What type of tests and treatments are involved?
- Are there any costs involved?
- What are potential side effects?
- How could this affect my daily life?
- What is involved and for how long?
What other choices do I have? What are their advantages and disadvantages?
If I have any questions about my rights as a research patient whom shall I contact?
All research participants receive a copy of their signed consent form for their own records and contact information is in the form.
What is a blinded study?
A blinded study is done so that neither the researchers' nor the participants' expectations about the experimental treatment can influence the study results.
What is the difference between a single and double-blinded study?
In a single-blinded study participants do not know whether they are in an experimental group or a control group. In a double-blinded study, neither the participants nor the researchers know which participants are in a group.
What is a controlled study?
In a controlled study, participants are assigned either to an experimental group or to a control group. Participants in the control group are used as a standard for comparison. For example, a study may have two groups, an "experimental group" and a "control group." The experimental group is given the experimental treatment under study, while the control group may be given either the standard treatment for the illness or a placebo. At the end of the study, the results of the two groups are compared.
How does randomization prevent bias?
Research subjects are randomized in clinical trials so that bias does not weaken the study results. Bias refers to human choices, beliefs or any other factor besides those being studied that can affect a clinical trial's results. If physicians or participants themselves choose the group, assignments might be personally influenced and therefore unevenly slanted toward one side or the other.
What is an experimental group?
Study participants in the experimental group receive the drug, device, treatment or intervention under study.
What is the difference between a treatment trial and a prevention trial?
A treatment trial tests new treatments (new drug, approaches to surgery or radiation therapy, new combinations of treatments or methods may also be tested). A prevention trial tests new approaches-such as medicines, vitamins, minerals or other supplements-that doctors believe may lower the risk of a condition.
What is a placebo?
A placebo is an inactive agent used for testing against the active drug. The results of the active compound are compared with the placebo to better understand the actions of the active drug.
Can I quit or leave a study at anytime?
Yes. Participation in a research study is voluntary. You may leave at any time for any reason. The principal investigator can withdraw you from the study if new potential risks are reported and if you are no longer benefiting from the treatment
The Maro Family Story
Robert Maro, MD ’56, was given three months to live. But thanks to a clinical trial at Jefferson, he was able to spend an entire year enjoying each day to the fullest.
“Just having my dad around that extra year allowed the young grandchildren to get to know him better,” says Pat, a certified diabetes educator from Moorestown, New Jersey. “He was able to attend the weddings of two of his grandchildren, to go on vacation, go out to dinner with my mom twice a week, and to arrange for closure.”
