The Benefits And Risks Of Participating In Clinical Trials

March 2, 2023

Clinical trials are one of the essential steps in developing medicines and other medical treatments. They are designed to assess a product’s safety, effectiveness, and side effects before the general public approves it. For those looking to participate in clinical trials, there are many benefits. Getting paid to help advance medical science can be a great way to contribute to the greater good. However, risks associated with participating in clinical trials should be considered. This article will explore both sides of the coin; we will discuss the potential benefits and risks associated with participation so you can decide whether it is right for you.

What Are Clinical Trials?

Clinical trials are research studies conducted by CROs where people volunteer to test new treatments or interventions for diseases and conditions. These treatments may be new combinations of medicines, new surgical procedures or devices, or new ways to use existing treatments.

People participating in clinical trials can play a vital role in developing new treatments and contributing to medical science. However, it is essential to remember that clinical trials are research studies, not medical care. The primary purpose of clinical trials is to generate information about the safety and efficacy of new treatments, not to provide therapy for participating patients.

There are also some risks associated with participating in clinical trials. Before enrolling in a trial, these risks should be discussed with a physician or other healthcare professional. Clinical trial participants should also know they may be required to take medication or undergo medical procedures with unknown risks. Before deciding, weighing the potential risks and benefits of participating in a clinical trial is essential.

The Different Types Of Clinical Trials

There are several clinical trials, each with advantages and risks.

  • Phase I Trials

These trials test a new drug or treatment in a small group of people (usually 20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects. Because these trials are early in the research process, a higher risk is usually involved.

  • Phase II Trials

These trials continue to test the safety of a new drug or treatment and begin to look at whether it is effective. They are usually larger than Phase I trials (100-300 people) and last longer (several months to two years).

  • Phase III Trials

These trials test a new drug or treatment in large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, and compare it to standard treatments. They are generally longer than Phase II trials (several months to four years) and often involve multiple sites nationwide or internationally.

  • Phase IV Trials

Post-marketing surveillance studies occur after a new drug or treatment has been approved by the FDA and used by the general public. They help researchers monitor the long-term safety and effectiveness of the medication or treatment.

Pros And Cons Of Participating In A Clinical Trial

The decision to participate in a clinical trial are personal. Before enrolling in a study, there are many factors to consider, such as the type of cancer, stage of disease, treatment options, and the trial’s location.

The potential benefits of participating in clinical trials:

  • Access to new and promising treatments that are not yet widely available.
  • The opportunity to contribute to medical research and potentially help others with cancer in the future.
  • Close monitoring by experienced medical professionals during the trial.
  • The chance to receive state-of-the-art care at leading cancer centers.

There are also some risks involved with clinical trials, such as:

  • Side effects from new treatments being tested can be more severe than standard therapies.
  • Clinical trials may be discontinued at any time if the treatment is not working or is found unsafe.
  • There is no guarantee that you will receive the experimental treatment – you may be randomized to receive standard therapy instead.
  • You may have extra doctor’s appointments and tests during the trial process.

Before deciding to participate in a clinical trial, discussing the potential risks and benefits with your doctor is essential.

How To Find A Clinical Trial?

When finding a clinical trial, the best place to start is with your physician. They will be able to provide you with a list of trials that are currently underway and help you determine if you are eligible to participate. You can also search for clinical trials online through This website is maintained by the U.S. National Library of Medicine and provides information on federally and privately funded clinical trials being conducted worldwide. Once you have found a clinical trial that interests you, you must contact the study coordinator to learn more about the trial and whether or not you qualify to participate.

Things To Expect During Participating In A Clinical Trial

When you participate in a clinical trial, you can expect to be closely monitored by the research team. They will track your progress and collect data about your health. You may also have to take medication or undergo medical procedures during the trial.

Clinical trials are an important way to test new treatments and determine if they are safe and effective. But they also carry some risks. Before you decide whether or not to participate in a trial, these risks should be discussed with you.

Some possible risks include the following:

  • Side effects from the treatment being tested
  • Discomfort from procedures or tests done as part of the trial
  • Time commitment required for participation
  • Costs associated with participating in the trial

Before enrolling in a clinical trial, ensure you understand the risks and benefits involved. Discuss your concerns with the research team and your doctor to help you make an informed decision.


Participating in a clinical trial can be an excellent opportunity for those interested in contributing to medical advancements and advancing their well-being. It is essential, however, to consider the possible risks of participating in such trials so that you are fully informed before making any decision. Weighing your options and researching the potential benefits and risks of participating will help you make an informed decision about whether or not it is right for you.
