Mission:

ADvantage Therapeutics is developing novel therapeutics to treat neurodegenerative conditions with a major focus on Alzheimer’s Disease (AD).

We are currently approved for Phase 2 clinical trials in Europe and possess an ILAP Passport designation from MHRA in the UK which may permit simultaneous clinical enrollment and early commercialization in the U.K after phase 2. With a dedicated research team and laboratory at the Vienna BioCenter, ADvantage is developing potentially paradigm-changing therapies to treat AD and other diseases of aging.

About Us


Our work suggests that our lead therapeutic (AD04™) modulates the immune system to provide patients with a unique positive effect on the course of Alzheimer’s Disease pathology. Our vision is to provide patients with a disease-modifying therapeutic for early Alzheimer’s Disease, thereby making the world a distinctly better place.

Our Values


We Put the Patient First

All decisions are made with the best interest of the patient. Period.

We Go Against the Grain

Root-cause explanations — with experimental evidence — drive our work and may overturn widely held assumptions. Knowledge building is in our DNA.

We Do the Right Thing

Integrity is key. We seek win-win relationships with stakeholders inside and outside the organization. We are only as good as our word.

We Have Grit

Entrepreneurs at heart, we thrive taking on significant challenges and breaking new ground. In the words of Marie Curie, “I was taught that the way of progress was neither swift nor easy.”

Previous Next

“One sometimes finds
what one is not looking for”

How a potentially disease-modifying compound for Alzheimer's Disease was discovered.

Over the last 20 years, Alzheimer’s research concentrated on therapies to produce antibodies against different amyloid-beta peptide species, which were shown to accumulate in the brains of Alzheimer’s patients. However, clinical trial efficacy proved elusive.

“The power of Science”

In 2014, the research team led by Drs. Frank Mattner, Walter Schmidt and Achim Schneeberger orchestrated a double-blinded, randomized clinical phase 2 trial with a vaccine candidate against AD in 332 Alzheimer’s patients. In this trial, AD04™ (based on Alhydrogel™) served as a control group.

“ADvantage Therapeutics is born to achieve the mission”

Unexpectedly, the patients from the control group significantly benefited from the AD04™ application. Patients treated with AD04™ saw reduced hippocampal shrinkage—a region critical for memory and spatial orientation—and a corresponding slowdown in cognitive decline.

In 2021, Frank Mattner, Walter Schmidt, Agustin Fernandez and Jeffrey Madden founded ADvantage Therapeutics Inc. to provide Alzheimer’s patients with a transformative, life-enhancing treatment.

Summary of Phase 2:
AD04™, a Unique Compound
with Disease Modifying Activity

Large Group of AD Patients Diagnosed According to Biomarker Enhanced Criteria (Phase 2 Clinical Study)

The 2mg IMM-AD04™ control arm of the trial showed a statistically significant slower decline over the combined 4 other groups on clinical outcomes (Cognition and Quality of life) and MRI hippocampal volume as biomarker.

OUR SCIENCE

Our product candidate, AD04™, is a known immuno-stimulant: this compound has been widely used as an adjuvant in human and animal vaccination programs and has a well-established safety record. However, injection of this compound as single ingredient for the treatment of AD is a proprietary and patented approach.

Our data obtained in patients with early AD indicated that AD04™, applied repeatedly to the subcutis of the upper arm induced a statistically significant slower decline over the combined 4 other groups on clinical outcomes (e.g. cognition and quality of life) and MRI hippocampal volume as biomarker. Importantly, reduced loss of the hippocampal volume correlated with significantly less decline in cognitive measures, e.g., adapted Alzheimer’s Disease Assessment Scale-cognitive (aADAS-cog), but not in functional endpoints supporting AD04™ as a therapeutic compound.

AD04™ tested in the respective clinical trial arm (n=51 patients) was safe and well tolerated. There was neither evidence for autoimmunity nor for hematological abnormalities or hepato-/nephrotoxicity.

A thorough proteomics analysis reveals that the peripheral inflammation caused by AD04™ translates in the brain in a significant change of expression of several proteins associated with mechanisms of lipids elimination. In turn, this leads to a reduction of inflammation in the brain and an activation of microglia to clean up waste molecules.

OUR PIPELINE

Our clinical developments and accomplishments leading to a
consistent success.

The world desperately needs disease-modifying therapies for AD: we combine immunology and neuroscience to create first-in-class therapeutics.

The Klotho ‘longevity’ protein

Klotho is a pleiotropic protein involved in the protection and regeneration of multiple organ systems, among others the brain, heart, kidneys, lungs, and bones. Klotho levels may become diminished by age, disease or genetics, triggering a host of diseases. 3600+ publications have described the importance of Klotho in numerous ways.

A safe, efficacious and adjustable mRNA approach

Supplements and exercise bring modest improvements in Klotho levels, direct injection of the protein is not effective outside the lab, DNA interventions are irreversible and mostly cannot be dosed. Therefore, we have adopted, and protected with numerous patents, an mRNA approach. IV administration triggers the endogenous secretion of the Klotho hormone, that may be modulated depending on the patient’s initial Klotho levels and desired therapeutic effect. Our own preclinical studies have shown efficacy and safety in animal models.

Clinical Development

Our proprietary mRNA is delivered using nanocarriers for repeated administration that are safer than traditional LNPs. We plan for a phase 1 trial starting early 2026.

These developments are hosted by a spinoff company, Klothea Bio Inc. We are proud to partner with Healthy Longevity clinic that has been chosen as a semifinalist in the $101 million XPrize Healthspan competition for its approach to increase health span with our proprietary klotho mRNA therapy.

OUR TEAM

We will sustain a knowledge-building culture that combines leading-edge scientific skill, unencumbered by conventional assumptions, with a passion for bringing paradigm-changing medical treatments to patients worldwide.
