# Ozempic's Impact Beyond Weight Loss: New Alzheimer's Trial Results Revealed | Navigating Ozempic Podcast

In this eye-opening episode of Navigating Ozempic, we examine the groundbreaking EVOKE and EVOKE Plus trials testing semaglutide's effects on Alzheimer's disease. Despite Ozempic's remarkable $18.59 billion in global sales and unprecedented GLP-1 research activity in 2025, these Phase 3 trials delivered surprising results. While the medication improved certain Alzheimer's biomarkers, it failed to slow cognitive decline compared to placebo in over 3,800 participants with mild cognitive impairment or early-stage Alzheimer's.

We explore why researchers pursued this connection between GLP-1 medications and neurodegenerative diseases, what the results mean for current Ozempic users, and how this affects the expanding landscape of GLP-1 research. Learn why 16.4% of all global medical trials currently focus on GLP-1 medications, with Eli Lilly and Novo Nordisk leading innovation in this rapidly evolving field.

Speaker 1 (00:00):
Welcome back to Navigating Ozenpic, the podcast where we break
down the latest developments surrounding this groundbreaking medication. I'm your host,
and today we're diving into some significant news that emerged
just in the past few days. We'll start with some
major developments in the world of GLP one research and development.
According to Clinical Trials Arena, twenty twenty five is proving

(00:20):
to be a landmark year for GLP one trial activity.
In fact, sixteen point four percent of all trials being
conducted globally are happening right now in this year. What's
driving this surge a combination of stronger funding, fewer trial cancelations,
and faster movement from initial planning to actual study launchers.
The United States is leading the charge with thirty four

(00:43):
point one percent of all GLP one trials, followed by
China at twenty seven point two percent. Now, when it
comes to the major players in this space, Eli Leeley
is currently initiating the highest number of trials for GLP
one medications, with Novo Nordisk following close behind. Speaking of
Novo Nordisk, their flagship GLP one product, o Zeenpic, had

(01:04):
an extraordinary year in twenty twenty four, the medication achieved
more than eighteen point five nine billion dollars in global sales,
making it the company's best performing product. But here's where
things get particularly interesting. Listeners. Novo Nordisk recently announced results
from two phase three trials called Evoke and Evoke Plus,
and these results represent a significant pivot in how we're

(01:27):
thinking about azepic and similar medications. According to Novo Nordisk
and Alzheimer's Research United Kingdom, these trials tested whether semaglutide,
the key ingredient in a zepic and wegovi, could help
treat Alzheimer's disease. The trials enrolled more than thirty eight
hundred adults with mild cognitive impairment or early stage Alzheimer's disease.

(01:49):
Here's what happened. The oral version of semagluetide did lead
to some improvements in certain disease recreate lated biomarkers, but
critically those changes did not translate into actually slowing disease progression.
Both the Evoke trial, which focused on people with early
stage Alzheimer's and signs of amyloid protein in their brains,

(02:09):
and the Evoke Plus trial, which included people with additional
blood vessel damage, failed to show that the drug outperformed
placebo in slowing cognitive decline. Now why were these trials
even conducted in the first place. While researchers have been
exploring a connection between type two diabetes, obesity, and dementia risk,
some evidence suggests that people taking GLP ie medications like

(02:32):
semaglutide for extended periods may be less likely to develop dementia. Additionally,
smaller early phase trials had shown some promise, with participants
experiencing slower memory decline and less brain shrinkage. However, these
larger phase three trials tell a different story. Interestingly, the
drug did appear to change certain biological markers associated with

(02:53):
Alzheimer's disease, but those changes simply didn't translate into meaningful
clinical benefits for patients. Alzheimer's Research United Kingdom emphasizes that
while there is some evidence suggesting GLP one agonists might
help reduce dementia risk in people with obesity or type
two diabetes, these medications are not currently approved or recommended

(03:15):
specifically for treating dementia or supporting brain health. This news
also highlights a broader pattern in DLP one research. Another
GLP one medication, exonotide, recently showed no difference in Parkinson's
disease progression between those taking the drug and those receiving placebo.
So while these medications have shown remarkable success in treating

(03:38):
type two diabetes and supporting weight loss, their applications in
neurodegenerative diseases remain uncertain. What does this mean for listeners
taking ozepic or considering it If you're using ozepic for
type two diabetes or weight management. These trial results don't
change the easy established benefits of the medication. However, they

(03:59):
do underscore an important message. Currently, there's no evidence supporting
the use of ozepic or similar GLP one medications, specifically
for dementia treatment or prevention. Looking forward, researchers are shifting
their focus toward combination treatments and real world data analysis
to better understand the long term effects of these medications
and identify which patients might benefit most from them. Thank
