Advantages and Disadvantages of participating in a Clinical Trial?

Introduction:

Clinical trials are a vital component of medical advancements, offering the opportunity to test new treatments and improve healthcare outcomes. For individuals considering participation, understanding both the benefits and challenges is essential to make an informed decision. This article highlights the advantages and disadvantages of clinical trials, alongside key questions to ask before joining, to help you assess whether this path aligns with your health goals and lifestyle.

1) The Advantages

Participating in a clinical trial helps advance research.
When a new treatment is developed, it must go through phase 2 and phase 3 trials, as we discussed in our previous post. Its effectiveness must be proven—usually (depending on the illness)—in a double-blind study. This means that neither the doctor nor the patient knows whether the treatment or a placebo (or a reference treatment) is being given. This process is designed to avoid any conscious or unconscious bias in evaluating the treatment’s effects.

Participating in a clinical trial means closer medical monitoring.
During the study, you’ll see the study doctors regularly. Often, these are renowned experts in the field. You’ll have frequent checkups where your symptoms are carefully examined. You can ask as many questions as you like. This often leads to better disease management during the study—and even after.
In some studies, you may even have teleconsultations, which saves time on travel.

Discover a new treatment before it’s available.
The treatment being tested is only available to study participants. If it eventually reaches the market, you’ll already know whether it works for you. This makes getting a successful prescription more likely. If the treatment doesn’t make it to market but worked for you, you can ask to try a medication from the same family—which may also work for you.

2) The Disadvantages

It may take up your time.
If the study isn’t virtual, you’ll need to travel to see the study doctor. Even if it’s fully virtual, you’ll be required to keep a daily symptom diary. (We recommend doing this anyway—even outside a clinical trial—as it helps with diagnosis and treatment, as we mentioned in a previous post.) You may also need to undergo extra tests (imaging, bloodwork, etc.).

You can’t be sure of the new treatment’s effectiveness or safety.
By definition, a new treatment in a clinical trial isn’t guaranteed to work. In fact, you likely already know that no treatment works for 100% of people—but at least the ones on the market have shown effectiveness in the majority of cases. There’s also a higher risk of side effects. By the time a treatment reaches phase 2, it has already been tested for safety in phase 1 on healthy volunteers, but side effects may still be discovered in patients during phases 2 or 3. The risk is low, but not zero.

You may not receive the treatment being studied.
In many trials, the new treatment must be compared to a placebo to prove its effectiveness. If you’re in the placebo group, you won’t receive the new treatment. The upside? You’re less likely to experience side effects! The downside? Placebos are typically less effective than the actual treatment.
In some studies, all participants are guaranteed to receive the product—just in two different periods: one with the new treatment and the other with the placebo, alternately. (Of course, neither the doctor nor the participant knows which is which, to preserve the “double-blind” setup.)

3) Questions to Ask

Before deciding whether or not to join a clinical trial, here are some questions you can ask the study team:

• What is the goal of this study?

• How long will the study last?

• What are the risks?

• What’s the chance I’ll be placed in the placebo group?

• How does this study differ from standard care for this illness?

• Can I keep taking my usual medications during the trial?

• Can I still see my regular doctor?

• How will the research findings be shared?

• Are there any additional costs?

• Is there financial compensation?

Conclusion:

Clinical trials offer unique opportunities to contribute to research, access innovative treatments, and receive specialized medical care, but they also come with potential risks and commitments. By carefully weighing these factors and asking the right questions, participants can make confident decisions about joining a study. Whether it’s the chance to help shape future treatments or improve personal disease management, clinical trials have the potential to create meaningful impacts in healthcare.
