Considering a Clinical Trial? Here's What You Should Know

Facing a new diagnosis, reaching a treatment plateau, or simply looking for ways to actively manage your health can bring you to an unexpected crossroads. For many, this is the moment the words "clinical trial" first enter the conversation.

It is completely normal to feel a wave of mixed emotions when considering clinical research. You might feel a glimmer of hope at the prospect of a new option, paired quickly with anxiety, confusion, or a barrage of questions. Is it safe? Am I just a guinea pig? Is this only for people who have run out of choices?

If you're asking these questions, you're approaching the decision thoughtfully. Exploring a clinical trial isn't about making a quick commitment, it's about learning enough to decide whether research fits your personal health goals, lifestyle, and comfort level. The more you understand, the more confident you'll feel in whatever choice you make.

Welcome to part one of our four-part clinical research educational series. At Kalo, we believe that health is a collective journey. Over the next few weeks, we will break down the complexities of clinical trials so you can make an informed choice that aligns with your health goals, your values, and your life. Today, we are starting at the very beginning: the "front door" of clinical research.

What is a Clinical Trial?

At its core, a clinical trial is a carefully designed research study involving human volunteers. Its primary goal is to answer specific scientific questions about how a new medical treatment, device, or intervention affects human health outcomes.

Many of today's medical treatments became possible because individuals chose to participate in carefully regulated clinical research. Their willingness to contribute has helped researchers better understand diseases, improve treatment options, and advance healthcare for future generations. However, a new treatment does not just jump from a laboratory bench to a doctor's prescription pad overnight. It must move through a highly regulated, step-by-step process known as clinical phases:

• Phase I: Tests a new treatment in a small group of people (typically 20 to 100) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.

• Phase II: Explores effectiveness and evaluates safety in a larger group of people (usually several hundred) who have the specific condition being studied.

• Phase III: Confirms effectiveness, monitors side effects, and compares the new treatment to standard treatments. This phase often involves thousands of people.

• Phase IV: Occurs after a treatment has been approved and is on the market to gather information on long-term risks, benefits, and optimal use.

  
  

Throughout every single phase, independent review boards, medical ethics committees, and government regulators closely monitor the study. At Kalo, we operate under a strict philosophy: data is powerful, but people always come first. Ethics and safety are never sacrificed for efficiency.

The Different Types of Clinical Research

When people hear "clinical trial," they often picture a patient taking a brand-new pill. While that is a common scenario, clinical research is actually a broad umbrella encompassing several different types of studies.

Interventional Trials

In an interventional study, researchers give participants a specific treatment, drug, device, or procedure to measure its impact on their health. This could mean testing a new treatment for type 2 diabetes, a new asthma inhaler, or a novel approach to weight health.

Observational Studies

In these studies, researchers do not assign any new treatments or change your routine medical care. Instead, they simply observe and gather data on volunteers in their natural environments or during their standard treatment plans to understand how health conditions progress over time.

Prevention, Diagnostic, and Screening Trials

Not all trials focus on treating an active illness:

• Prevention trials look for better ways to prevent disease in people who have never had it (such as testing a new vaccine).

• Diagnostic trials look for better tests or procedures to identify a particular condition.

• Screening trials test the best way to detect health conditions early, before symptoms even appear.

  
  

Why Representation Matters: Who Can Participate?

There is a widespread misconception that clinical trials are an act of desperation, a "last resort" reserved exclusively for the terminally ill. This is a myth. Many trials focus on everyday, manageable conditions like blood pressure, cholesterol, eczema, or respiratory health.

But there is a much bigger reality we need to talk about: medicine is only as safe as the research behind it, and right now, research doesn't reflect all of us.

Over 75% of clinical trial participants in the U.S. are white. Yet, chronic diseases like diabetes, heart disease, and respiratory illnesses disproportionately impact Hispanic, Black, Indigenous, Asian American, Hawaiian, and Pacific Islander communities. Women and older adults are also frequently underrepresented.

When everyone is included, medicine works better for everyone. At Kalo, our purpose is closing this gap. We build trials designed with real lives in mind, ensuring that communities that face the highest health risks are actually represented in the data that shapes their treatments.

Eligibility Criteria

To participate, every study operates under a strict roadmap called a protocol, which defines eligibility through:

• Inclusion criteria: The factors that allow someone to enter the study (e.g., age, specific health condition).

• Exclusion criteria: The factors that protect someone by preventing entry (e.g., a conflicting medication).

These criteria exist to protect participant safety by avoiding known risks and ensuring the scientific results are accurate.

Making a Confident, Well-Informed Choice

As you learn more about a study, you'll hear the phrase informed consent. While many people think of it as paperwork, it's actually much more than a signature. It's an ongoing conversation designed to ensure you understand what participation involves before joining, and throughout the study if questions or concerns arise.

Before you decide whether to participate, the research team should clearly explain every important aspect of the study in language that's easy to understand, including:

• The exact purpose of the research.

• What treatments or procedures you will undergo.

• The known risks, side effects, and potential benefits.

• How much of your time the study will require.

At Kalo, we believe trust is earned through transparency, respect, and clear communication. Every participant deserves to understand exactly what a study involves and to feel supported throughout the process. You have the right to leave a clinical trial at any time, for any reason, with absolutely no penalty to your standard medical care.

The Right Decision Is the One That's Right for You

Every person's healthcare journey is different, which means every research decision will be different, too. Some people feel excited about participating in research, while others decide it's not the right fit at that point in their lives. The best decision is the one that reflects your health needs, responsibilities, comfort level, and personal priorities.

For some, the opportunity to receive study-related care at no cost, receive potential compensation for time, and contribute to a future where medicine represents their community is a powerful motivator. For others, the timing might not be right. Both choices are completely valid.

Taking the Next Step

Making an informed decision doesn’t happen all at once. Now that you understand the basic landscape of clinical trials, the next step is moving from general knowledge to specific exploration.

To do that, you need to know how to advocate for yourself. 

Next week, we’re going to talk about Questions to Ask Before Joining a Clinical Trial. We will give you a practical toolkit: a checklist of the exact questions you should ask the research team and your doctor about logistics, costs, and care before ever signing on the dotted line.

Want to learn more about our Active Trials at Kalo? We’d love for you to see how we provide safe, respectful, no-cost care rooted in real communities.

In gratitude, we thrive!
