Clinical Trials Demystified
Behind the Scenes of Alzheimer's Research
For many families, Alzheimer's clinical trials feel mysterious — maybe even intimidating. You hear about them in the news, you see recruitment ads, but what actually happens if you or your loved one enrolls?
Are they safe?
Are participants "guinea pigs"?
How much time will it take?
Who benefits from the research?
When you're facing an Alzheimer's diagnosis, the word "research" can feel cold and clinical—all protocols and statistics, lacking warmth or humanity. But here's what I learned through six years as my mother's study partner in the Leqembi trials: behind every clinical trial is a community of people choosing hope over helplessness, action over waiting, and connection over isolation.
Clinical trials aren't just about testing drugs. They're about refusing to be passive passengers on a journey you didn't choose. They're about families who look at uncertainty and say, "We're going to do something." And whether you ultimately choose to participate or not, understanding how trials work gives you back something precious: agency.
So let's demystify this together—not just the science and logistics, but the human experience of being part of research that could change everything.
In this guide, we'll answer all those questions and more — giving you a clear look at the science, logistics, and human stories behind Alzheimer's research. By the end, you'll know exactly how trials work, whether participation might make sense for your family, and how these studies lead to treatments like Leqembi and Kisunla.
Section 1 – Why Clinical Trials Matter in Alzheimer's Research
Why Alzheimer's has been one of the hardest diseases to treat
How each FDA-approved drug starts in a lab and ends with real patients
The "pipeline" of research: pre-clinical → Phase 1 → Phase 2 → Phase 3 → FDA review
Examples of major trial successes and what we've learned from failures
Section 2 – How Clinical Trials Are Designed
Types of Alzheimer's Trials
Prevention trials – Target people at risk but not yet showing symptoms
Early-stage treatment trials – Focus on slowing progression in Mild Cognitive Impairment or mild dementia
Symptom management trials – Aim to improve memory, mood, or daily function without changing disease course
Caregiver intervention trials – Test ways to improve caregiver quality of life
Randomization & Placebos
Why placebos are used and how they keep data unbiased
What "double-blind" means (neither patient nor doctor knows who's getting the real drug)
The Timeline of a Trial
Recruitment – How patients are found and screened
Baseline testing – Cognitive exams, MRIs, bloodwork, PET scans
Treatment period – Infusions, pills, lifestyle interventions, or a combination
Follow-up – Safety checks and final evaluations
Section 3 – Who Qualifies for Alzheimer's Trials
Common Inclusion Criteria
Age range (often 50–85)
Diagnosis stage (MCI or mild dementia for many anti-amyloid trials)
Biomarker confirmation (amyloid PET scan or CSF test)
Common Exclusion Criteria
Advanced Alzheimer's
Certain health conditions (e.g., uncontrolled hypertension, bleeding disorders)
MRI findings that raise risk
Use of conflicting medications
Real-Life Story: Meet "Jim"
Jim, 71, joined a Kisunla trial after confirming amyloid plaques.
"I thought I'd feel like a lab rat," Jim says. "Instead, I felt like part of a team working toward something bigger than me."
Section 4 – The Role of the Study Partner
In most Alzheimer's trials, participants must have a study partner — someone who:
Attends key visits
Tracks symptoms and side effects
Helps ensure medication and appointments stay on schedule
Acts as a second set of eyes and ears
Why this role is crucial for accurate data and patient safety.
Section 5 – Safety in Clinical Trials
Institutional Review Boards (IRBs)
What they are and how they protect participants
How every protocol is reviewed for ethical standards
Ongoing Monitoring
Regular labs, MRIs, and health check-ins
Independent Data Monitoring Committees (DMCs) that can stop a trial if safety concerns arise
Real-Life Story: Meet "Lydia"
Lydia's trial was paused mid-way due to a safety review.
"At first, I was disappointed," she says. "But it made me trust the process more. They weren't going to risk our health for data."
Section 6 – Myths vs. Facts About Alzheimer's Trials
Myth: You're just a guinea pig.
Fact: Alzheimer's trials are highly regulated and participant safety comes first.
Myth: Placebo means wasted time.
Fact: Placebo data is essential for proving a treatment works, and you still get extensive medical monitoring.
Myth: Trials only help future patients.
Fact: Some participants see personal benefits, especially in prevention and early treatment trials.
Section 7 – Compensation & Costs
Many Alzheimer's trials cover all medical costs related to the study
Some reimburse travel, lodging, and meals
What's covered vs. what's not
Section 8 – How to Find Alzheimer's Clinical Trials
Where to Look

Who pays for scans, travel, and medications?
What happens when the trial ends?
Section 9 – The Human Side of Research: More Than Data
When my mother enrolled in the Leqembi clinical trial in 2019, I expected to encounter cold medical procedures and endless paperwork. What I didn't expect was the community we found—or how profoundly the experience would change both of us.
Why Families Choose to Participate
The motivations are as varied as the families themselves:
Hope for personal benefit - Access to cutting-edge treatments years before they're available to the public
Leaving a legacy - Contributing to science that could help their children and grandchildren
Staying active, not passive - Doing something, anything, rather than watching helplessly
Connection to purpose - Being part of something bigger than their own struggle
The best medical monitoring available - Regular check-ins, scans, and attention from top specialists
"Even if it doesn't help me," says Tom, 74, "it could help my grandkids someday. That makes it worth it."
The Unexpected Gift: Community
What surprised us most was the bond we formed with other trial participants and their families. In the waiting room before infusions, we swapped stories, celebrated small victories, and supported each other through setbacks. These weren't just fellow patients—they became friends who truly understood.
One study partner told me: "Before the trial, I felt so alone. Now I have this tribe of people who get it. We text each other. We celebrate when someone's MRI is clear. We're in this together."
How Participation Affects Caregivers
As a study partner, I discovered something profound: being actively involved in my mother's treatment was healing for me, too.
The helplessness of caregiving—watching someone you love decline while feeling powerless—is one of the hardest parts of Alzheimer's. But in the trial, I had a role. I was contributing to her care in a meaningful way. I had structure, purpose, and a team of professionals who valued my observations.
Research shows what I experienced firsthand: caregivers who participate in clinical trials often report:
Reduced feelings of helplessness
Better connection with their loved one
Access to resources and support
Sense of hope and forward momentum
The Emotional Complexity
Let's be honest: it's not all positive. There are hard days.
Waiting for safety scan results can be agonizing. The time commitment is real. If you're randomized to a placebo, the disappointment stings. And when the trial ends, there's grief in saying goodbye to that structure and community.
But here's what I tell families who ask me if it's worth it:
For us, participating in the trial wasn't just about whether the drug worked. It was about how we chose to face this disease—together, actively, hopefully. That choice transformed our journey in ways no medication alone ever could.
Different Paths, Same Spirit
Clinical trials aren't for everyone, and that's okay. Some families choose other paths—lifestyle interventions, spiritual approaches, complementary therapies, or simply maximizing quality time together.
What matters isn't which path you choose. What matters is that you choose something—that you refuse to let this diagnosis steal your agency, your hope, or your humanity.
Whether you join a trial or not, you're not alone on this journey. And there's power in making informed, intentional choices about how you'll face what's ahead.
