Why Participate in a Clinical Trial at Drexel?

Drexel University College of Medicine's clinical research program seeks to improve patient care through innovative approaches and new findings. By evaluating medicines, therapies and diagnostic tools, clinical research drives discoveries in health promotion and disease prevention to improve health.

What are clinical trials?

Clinical trials are research studies involving human participants that evaluate a new medical approach, device, drug or other treatment. They are performed with people who have volunteered to help answer a specific health question. For example, a clinical trial might determine whether a certain drug or treatment prevents a certain disease or condition.

Clinical trials are conducted in four phases, with each phase involving a larger number of participants.

Clinical Trials Phases

Who can participate in clinical trials?

Each clinical trial contains enrollment guidelines about who can and cannot participate. These guidelines are maintained to ensure the safety of participants and potential participants. They are also used to ensure that the purpose of the study is effectively answered.

The guidelines are never used to personally reject a person from a clinical trial. Each clinical trial will clearly state both inclusion and exclusion criteria. Inclusion criteria are a list of the factors that allow someone to participate. Exclusion criteria are a list of the factors that will disqualify a person from participation. In order to participate, a person must have all the factors listed in the inclusion criteria and not have any of the factors in the exclusion criteria. Both sets of criteria may contain factors based on age, gender, ethnicity, disease or condition (or lack of), fertility and other health factors.

What does it cost to participate in a clinical trial?

This will depend on the particular trial you seek to join. There are usually two types of costs in a clinical trial: costs for treatment that are considered "standard of care" and research costs that are associated with the research activity.

"Standard of care" costs are those that would have been part of your medical treatment or care if you did not enroll in the clinical trial. These treatment costs include but are not limited to drugs, routine laboratory tests, x-rays, scans, surgeries, routine medical care, and physician charges. You or your insurance company will be responsible for these "standard of care" costs.

Research costs are usually paid for by the trial at no cost to you. However, you will still be responsible for any co-payments and/or deductibles. There also may be additional costs, such as personal time and travel expenses, which may or may not be covered by a clinical trial. Please be aware that each trial is unique. The study team will go over the costs of participation with you before you agree to participate.

What are the benefits and risks of joining a clinical trial?

One way to gain access to promising new interventions is to participate in a clinical trial.

Although participating may not always be beneficial, there is reason to believe participating will be as good as or better than the current standard of care. The current standard of care was the result of past clinical trials, and a new research intervention may become the standard of care in the future.

All those receiving care are benefiting from someone who participated in a clinical trial in the past. By participating in a clinical trial today, you are helping advance medicine and, therefore, helping other patients in the future.

However, all clinical trials have risks. The new intervention being tested may have unknown side effects or other risks, which may or may not be worse than those from existing standard of care interventions. The research intervention may not work for you, even if it helps others. There may be inconveniences such as more frequent office visits and testing, as well as time and travel commitments.

The benefits of a well-designed clinical trial are:

  • The participant may gain access to new research treatment that may not be widely available;
  • The participant may obtain expert medical care at leading medical centers; and
  • The participant contributes to medical research and future medical treatments.

The risks of participating in a clinical trial are:

  • The patient may experience unpleasant, serious and even life-threatening side effects;
  • The treatment may not be effective; and
  • Participation may require more time and attention than receiving standard care (e.g., travel to the research site, additional tests or treatments, hospital stays, complex dosage).

Is it safe to participate in a clinical trial?


Before agreeing to participate, you will be asked to review and sign an informed consent document with your doctor. The consent form will explain the study's purpose, procedures and possible risks and benefits of participation in detail. If new benefits, risks or side effects are found during the course of the trial, you will be told about them so that you can decide whether or not you want to continue participating. Taking part in a clinical trial is completely voluntary and you can choose to stop participating at any time for any reason. Your health care providers will continue to care for you according to current best practices and highest standards of care, regardless of whether or not you continue participation in a clinical trial.


Local, federal and international laws protect clinical trial participants' physical safety and privacy. Several oversight committees approve and routinely monitor trials to make sure that the rights and safety of participants are protected. These committees have the ability to shut down a trial if it is deemed unsafe.

How are clinical trials funded?

Clinical trials are funded (or sponsored) by an array of institutions, individuals and organizations, such as physicians, medical institutions, medical academic centers, foundations, pharmaceutical companies and governmental agencies. The National Institutes of Health (NIH), the Department of Defense (DoD), and the Department of Veterans Affairs (VA) are examples of governmental agencies that sponsor clinical trials.

Clinical trials can be conducted in various places including hospitals, universities, medical offices, community clinics and research clinics.
