Clinical Trials: What They Are, What They Do, and How We Can Make Them Better

Clinical trials are the backbone of medical discovery. They’re how we find out if new treatments work, if they’re safe, and who benefits from them. But while they are essential for medical progress, clinical trials often fall short of their full potential—especially when it comes to serving the very people they aim to help: patients.

As someone who lives with chronic pain and has spent years advocating for better research and care, I’ve come to see clinical trials as both incredibly valuable and in desperate need of reform. In this article, we’ll explore what clinical trials are, what they’re good at, what they fail to do, and how we can—and must—improve them.


What Are Clinical Trials?

At their core, clinical trials are research studies involving human participants. They are used to test the safety and effectiveness of new treatments, procedures, or interventions. These could be new medications, devices, types of surgery, psychological therapies, or lifestyle changes.


Types of Clinical Trials

There are several different kinds of clinical trials, each with a specific goal. Some of the most common include:

🧪 Treatment Trials

Test new medications, surgeries, therapies, or combinations of treatments to assess safety and effectiveness.

🧬 Prevention Trials

Study ways to prevent disease or reduce the risk of recurrence—through medications, vaccines, or lifestyle changes.

🔬 Diagnostic Trials

Test new tools or procedures for diagnosing a disease or condition more accurately or earlier than current methods.

📊 Screening Trials

Evaluate the best ways to detect a disease in people who do not yet show symptoms.

💚 Supportive Care (or Quality of Life) Trials

Focus on improving the comfort, function, and quality of life for people with chronic illnesses or those undergoing serious treatments.

🔁 Observational Studies

Participants are observed in their usual setting without assigned interventions. These help researchers understand real-world outcomes, side effects, or disease patterns.


How Do Clinical Trials Work?

Clinical trials usually happen in four phases:

  • Phase 1: Tests safety and dosage in a few healthy volunteers or patients.
  • Phase 2: Looks at whether the treatment works and continues to monitor safety.
  • Phase 3: Compares the new treatment to the current standard of care in a larger group.
  • Phase 4: Happens after FDA approval to track long-term effects.

Trials are strictly regulated and follow protocols to protect participants and produce meaningful data.


What Do Clinical Trials Do Well?

Clinical trials have led to life-changing breakthroughs. Vaccines, cancer treatments, insulin, HIV medications, and countless other interventions were brought to the public through trials. They:

  • Rigorously test safety and effectiveness before broad use.
  • Provide structured ways to assess treatments under controlled conditions.
  • Offer hope and sometimes direct benefits to participants.
  • Create evidence that shapes healthcare guidelines and public health policy.

And when they work well, they uphold ethical standards, maintain participant safety, and deliver trustworthy results.


Where Do Clinical Trials Fall Short?

Despite their value, clinical trials often fail to:

✅ Include the People Most Affected

Many trials exclude older adults, people with multiple chronic conditions, those with disabilities, or those from marginalized communities. Chronic pain patients, for instance, are rarely part of trial design, yet the results are applied to them.

✅ Ask the Right Questions

Trials often focus on what’s easiest to measure (like blood tests or imaging) rather than what matters most to patients (like function, fatigue, or quality of life).

✅ Reflect Real-World Use

Strict eligibility criteria and tightly controlled settings mean trial results may not translate to everyday clinical practice.

✅ Communicate Results Back to Participants

Participants rarely hear what happened with the study they contributed to, a missed opportunity for trust and engagement.

✅ Include People with Lived Experience in Design and Governance

Patients and caregivers are rarely involved in shaping trials—yet their input could make the research more relevant, respectful, and successful.


How Are Clinical Trial Results Interpreted—And What Do They Mean for People with Lived Experience?

After a clinical trial is completed, researchers analyze the data to answer specific questions:

  • Did the treatment work better than the comparison (placebo or standard care)?
  • How safe was it?
  • How big were the benefits? How common were the side effects?
  • Were the results statistically significant (unlikely due to chance)?
  • Were they clinically meaningful (noticeable and important to patients)?

The interpretation is usually done by statisticians and investigators—who may or may not include patients in this process.

For people with lived experience (PWLE), this matters deeply.

A treatment might technically work, but if it doesn’t improve your daily life, it might not feel like a success. For example:

  • A new medication reduces pain scores by 0.5 points on a 10-point scale. Statistically significant? Maybe. But will you notice it? Maybe not.
  • A trial shows improved sleep—but only in lab conditions, not real life.
  • A device works well, but it’s too expensive, hard to access, or complicated to use.

That’s why interpretation must go beyond numbers. It must include patient voices to make sense of what the data means in real-world terms. Involving PWLE in interpreting results ensures that:

  • Benefits and risks are weighed through a patient-centered lens.
  • “Success” reflects more than just statistics—it reflects lived impact.
  • Researchers stay accountable to the people they hope to serve.

How Can We Improve Clinical Trials?

Here are five key steps we can take to improve clinical trials:

1. Include People with Lived Experience from the Start

Bring in patient advisors—not just as tokens, but as real partners—in designing the questions, selecting outcomes, and interpreting results. Patients know what matters most. Trust them to help guide the process.

2. Make Trials More Inclusive

Loosen exclusion criteria to reflect the people who will actually use the treatment. This is especially important for chronic pain, where comorbidities and complex lives are the norm.

3. Prioritize Patient-Centered Outcomes

Measure what matters to patients. If a treatment doesn’t improve how someone feels or functions, it’s not a success—no matter what the bloodwork says.

4. Improve Transparency and Communication

Participants deserve to know the results of the trials they were part of. Share findings in plain language, and invite participants to stay engaged throughout the process.

5. Make Participation Easier

Use telehealth, home visits, community-based sites, and flexible schedules to reduce barriers. Pay people for their time. Respect their contribution.


Final Thoughts: A Call for Human-Centered Research

Clinical trials will continue to be a pillar of medical innovation—but they must evolve. For too long, research has happened to people, rather than with them. It’s time for a more inclusive, humane, and effective model.

We don’t just need better treatments. We need better questions. Better partners. Better science. And above all, better respect for the people living with the conditions we seek to treat.

That’s how we turn clinical trials from a narrow pipeline of innovation into a truly transformative force for health equity, patient empowerment, and lasting change.
