May 20 is International Clinical Trials Day, a global observance that celebrates the launch of the first controlled clinical trial in 1747 by Scottish naval surgeon James Lind. It also honors the volunteers, researchers, and organizations who continue to carry the torch today—testing new drugs, devices, and therapies that improve and save lives.
Whether you’re passionate about health advancements or curious about the perks of participating in a clinical trial, this day shines a spotlight on the critical role clinical research plays in global healthcare.
What Is International Clinical Trials Day?
International Clinical Trials Day (ICTD) is recognized each year on May 20 to commemorate the date James Lind started what many consider the first ever modern clinical trial. His study tested how citrus fruit could prevent scurvy among sailors—a breakthrough that literally changed the course of history.
Fast forward nearly 300 years, and clinical trials are now a vital part of how we get everything from flu shots and allergy meds to cancer treatments and heart implants. No drug or device gets the green light without first going through a series of rigorous trials, typically involving human volunteers.
Why Are Clinical Trials So Important?
Clinical trials are the backbone of medical progress. Every safe, effective product on the market—whether it’s a pill, pacemaker, or patch—was once part of a research study.
Here’s why they matter:
- They help find cures – From life-saving cancer therapies to vaccines and pain relief, trials pave the way.
- They test safety and effectiveness – Trials ensure drugs and devices actually work and won’t cause harmful side effects.
- They offer early access – Some participants can try treatments before they’re available to the public.
- They protect public health – By following strict protocols and oversight, clinical research ensures that what reaches patients is both safe and beneficial.
What’s In It for Volunteers?
Let’s be honest: one of the best-kept secrets about clinical trials is the benefits for participants.
The perks can include:
- Compensation for your time – Many studies pay participants, and some offer thousands of dollars for overnight or extended stays.
- Free health screenings – Think physical exams, lab work, EKGs, and more.
- Free access to new treatments – You could receive cutting-edge therapy before it hits the market.
- Helping others – Your participation could lead to breakthroughs that benefit future generations.
Whether you’re motivated by the money, the mission, or a mix of both, clinical trials can be a smart, meaningful way to contribute to science while taking care of your own needs.
Who Can Participate in Clinical Trials?
You don’t have to be sick to volunteer. Many studies are looking for healthy participants to help researchers better understand how new drugs and devices behave in the body.
Depending on the study, eligibility might depend on:
- Age and gender
- Medical history
- Whether you take medications
- Whether you smoke, drink, or use certain substances
- Your lifestyle or level of activity
There are also studies designed specifically for patients with certain conditions like asthma, diabetes, migraines, or high blood pressure. Researchers are often looking for a diverse mix of people, which means your background and biology could make you especially valuable in a study.
How Are Trials Regulated and Kept Safe?
People often wonder if clinical trials are risky. The truth? Safety is a top priority.
Before a trial can start, it goes through multiple layers of review and approval—from scientific boards to ethics committees. Every detail is tracked, every side effect recorded. Participants are told exactly what to expect through a process called informed consent, which means:
- You know what you’re signing up for
- You can ask questions any time
- You can quit whenever you want—no strings attached
Your health and privacy are protected at every stage.
How to Get Involved on May 20
Even if you’re not ready to sign up for a study, there are still ways to take part in International Clinical Trials Day:
- Share your story if you’ve ever been in a trial
- Post on social media using #ICTD or #ClinicalTrialsDay
- Thank a researcher or volunteer in your community
- Visit a clinical research center near you to learn more
- Explore trials recruiting now (some websites let you search by location or condition)
You might even find a study that fits your lifestyle—and pays well, too.
The Altruism Angle: Doing Good While Earning Extra
Yes, many people are drawn to clinical trials because of the financial compensation, but nearly all volunteers say they also value the chance to help others. That’s the real beauty of clinical trials: you can make a difference while also helping yourself.
Think of it this way: by volunteering, you’re:
- Helping doctors develop better treatments
- Speeding up access to life-saving drugs
- Representing people who share your health profile
Supporting science in action
Celebrate the Progress, Fuel the Future
International Clinical Trials Day is more than a history lesson. It’s a reminder that every medical breakthrough begins with a question, a test, and a volunteer willing to raise their hand.
So, whether you’re curious about joining a study or simply want to honor the progress we’ve made—May 20 is a great day to get involved. Because the future of medicine isn’t just in the hands of scientists—it’s in the hands of people like you.
Ready to Make a Difference?
If you’ve ever thought about joining a clinical trial, there’s no better time than now. Whether you’re interested in earning extra income, accessing new treatments, or simply being part of something bigger, your participation matters.
Clinical trials can’t happen without people like you. Check out the current and upcoming trials conducted by QPS, and be sure to come back often as new opportunities are constantly added. You might be the missing piece in the next big medical breakthrough. Get involved. Get paid. Do good.
